OPEN HOURS MON–FRI | 9AM–6PM
Porsche Cayenne E-Hybrid has 15 NHTSA recalls (2019-2024) plus hybrid system, charging, and suspension TSBs. California lemon law rights explained.
You paid $90,000 or more for a Porsche Cayenne E-Hybrid. The badge promises Stuttgart engineering, a 17.9 kWh battery that lets you commute on electrons, and a twin-turbocharged V6 ready to launch when the grid runs thin. Instead, thousands of owners have spent mornings waiting for a jump-start because the 12V auxiliary battery died while the HV pack sat fully charged in the garage. Others watched the PCM screen go dark in reverse (twice) and heard a dealer call it a 'software thing' that's 'normal.' Some plugged into their home Level 2 charger and received nothing but a 'Charging Interrupted' message on a car that cannot perform its core PHEV function.
The 2019-2024 Cayenne E-Hybrid (E3 platform) carries fifteen NHTSA recalls: seatbelt buckle failures, two brake warning-lamp software defects, a steering column detachment risk, a rear axle recall that required a second recall to fix the first one's incomplete repairs, charging cable overheating, front axle control arm cracking, a fuel pump fuel-leak risk, and two distinct rearview camera failures spanning six model years. Above these recalls sit TSB-documented defects the NHTSA complaint database confirms: PASM compressor failures aggravated by the PHEV's extra battery mass, a hybrid system warning that strands owners in combustion-only mode, a 12V parasitic draw unique to the E-Hybrid's HV gateway, and OBC module charging failures distinct from the cable recall.
Under California's Song-Beverly Consumer Warranty Act, you don't need a single dramatic event. You need documented repair attempts (multiple visits for the same defect, or substantial time out of service) within the warranty period. Many owners who treated each problem as an isolated inconvenience have been building a lemon-law case without realizing it.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
driver seat cushion loose; seat fastener recall; seat may not stay secured
backup camera blank; screen goes black in reverse; rearview camera distorted
front suspension noise; stabilizer bar loose; vehicle pulls or clunks
brake pedal problem; reduced braking; unexpected braking; brake warning light
brake pedal problem; reduced braking; unexpected braking; brake warning light
transmission shifts unexpectedly; hesitation; harsh shift; transmission warning

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
driver seat cushion loose; seat fastener recall; seat may not stay secured
A rear seatbelt buckle that can break under crash load is a direct occupant-safety defect. Under Song-Beverly, any recall-backed safety defect that remains unrepaired after a reasonable number of warranty attempts — including delays in dealer parts availability — may support a claim. 2019 Cayenne E-Hybrid owners who experienced repeat buckle or belt engagement issues before the recall remedy was applied should document every dealer visit, including any 'parts on order' notation.
Porsche will notify owners, and dealers will replace the passenger rear seat belt buckle, free of charge. The recall began November 30, 2018. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AJ09.
backup camera blank; screen goes black in reverse; rearview camera distorted
FMVSS-111 non-compliance means Porsche acknowledged a safety defect: the backup camera failed to display promptly in reverse. For 2019 Cayenne E-Hybrid owners, if the camera delay persisted after the AKA0 software update or required multiple dealer visits, each visit counts under Song-Beverly. This recall's narrow 2019 MY scope means owners of that year have a documented, manufacturer-acknowledged defect.
Porsche will notify owners, and dealers will update the related software, free of charge. The recall began April 19, 2019. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AKA0.
front suspension noise; stabilizer bar loose; vehicle pulls or clunks
Loose shock absorber forks can cause unpredictable handling changes at highway speed — a clear Safety-tier defect. On the heavier Cayenne E-Hybrid, suspension component stress is higher than on the gas variant, increasing the risk profile. 2019 owners who returned to the dealer for recurring suspension noise or handling complaints after the AKA2 remedy should document those visits as potentially linked to this or the related trailing-arm recall (iss-07).
Porsche will notify the owner, and a dealers will replace the shock absorber forks, free of charge. The recall began April 19, 2019. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AKA2.
brake pedal problem; reduced braking; unexpected braking; brake warning light
A brake pad wear warning that never illuminates can allow pads to wear to metal-on-rotor contact without driver awareness — a direct safety defect under Song-Beverly's broad coverage of defects impairing safety. 2019 E-Hybrid owners who had brake pad replacement or brake noise complaints should check whether the AKA1 cluster software update was applied; if their brakes were damaged due to the warning failure, that strengthens the claim.
Porsche will notify owners, and dealers will update the instrument cluster software, free of charge. The recall began April 19, 2019. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AKA1/AKA0.
brake pedal problem; reduced braking; unexpected braking; brake warning light
This recall (AKB8) supersedes 19V115, meaning Porsche needed a second attempt to fix the brake-pad warning lamp failure — itself a pattern relevant to lemon law. Owners of 2019-2020 Cayenne E-Hybrid who had the AKA1 fix applied under 19V115 and then received a second recall notice should document both dealer visits; two recall remedies for the same safety defect are strong evidence of repeated repair attempts under Song-Beverly.
Porsche will notify owners, and dealers will reprogram the instrument cluster, free of charge. The recall is began December 13, 2019. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AKB8. Note: This recall supersedes recall 19V115 and includes vehic
transmission shifts unexpectedly; hesitation; harsh shift; transmission warning
An ATF leak from a defective weld can cause transmission slippage or failure if fluid level drops before the leak is detected. For Cayenne E-Hybrid owners, the ZF 8HP shares ATF circuits with the hybrid drive unit, making an ATF leak a more serious reliability concern than on a conventional automatic. If the dealer inspected but did not replace the pipe, or if ATF loss symptoms recurred after the ALA5 repair, document those visits — each adds to the repair-attempt record.
Porsche will notify owners, and dealers will inspect the transmission oil pipe and replace it if necessary, free of charge. The recall began September 8, 2020. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is ALA5.
front suspension noise; stabilizer bar loose; vehicle pulls or clunks
A stress-corrosion lock nut failure on the rear trailing arm can lead to wheel camber changes or, in severe cases, wheel detachment — a catastrophic safety scenario. Porsche later issued a follow-up recall (22V040 / iss-10) specifically because the AMA9 repair was not consistently executed, indicating a known repair-quality problem. 2021 E-Hybrid owners who received both AMA9 and ANA1 repairs have documented evidence of two separate remedy attempts for the same defect cluster.
Porsche will notify owners, and dealers will replace the lock nuts, free of charge. The recall began on June 18, 2021. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AMA9.
airbag warning light; passenger airbag may not deploy; SRS warning; occupant detection fault
An improperly calibrated occupant classification system can cause the front passenger airbag to fail to deploy in a crash — a life-safety defect. For Cayenne E-Hybrid Coupe owners (specifically named in 21V318), the AMB0 remedy (installing a missing seat-back heating element) must be verified complete on the repair order. If a dealer closed the recall without installing the heater, the defect remains uncured and the owner retains full Song-Beverly rights for that uncompleted repair.
Dealers will install a heating element, free of charge. Owner notification letters were mailed June 25, 2021. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AMB0.
sticky steering; steering wheel feels stuck; increased steering effort; steering recall
A failed screw connection between the steering column and steering box can cause complete loss of steering control — one of the most dangerous defect categories under California lemon law. If a 2021 Cayenne E-Hybrid owner experienced any steering-feel change, unusual steering effort, or clunking from the column before the AMB4 screw replacement, those symptoms should be documented. Dealers who dismissed the complaint without checking the steering column connection may have failed to repair a known safety defect.
Dealers will install a new screw, free of charge. Owner notification letters were mailed August 24, 2021. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is AMB4.
front suspension noise; stabilizer bar loose; vehicle pulls or clunks
This recall exists because the prior AMA9 repair (iss-07) was not consistently verified for rear axle alignment — a quality-control failure by the manufacturer's dealer network. Owners who had both AMA9 and ANA1 recalls performed have effectively documented two repair visits for the same rear-axle structural defect cluster. Under Song-Beverly, this pattern — original recall, improper repair, second recall to correct the first — is compelling evidence supporting a buyback claim.
Dealers will inspect the rear axle, adjust the alignment as necessary, and replace any prematurely or unevenly worn tires, free of charge. Owner notification letters were mailed March 10, 2022. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is ANA1.
tail light out; exterior light warning; reduced rear visibility
Hazard and parking lights that fail to illuminate after engine shutdown create a direct collision risk when the vehicle is parked on a roadway or in a poorly lit area — a FMVSS-108 non-compliance Porsche acknowledged. The 10-second gateway shutdown window that prevents light activation is a software defect. 2024 Cayenne E-Hybrid owners who experienced this before the APB1 software update should document any parking-related incidents or repeat visits to preserve their Song-Beverly rights.
Dealers will update the gateway control unit software, free of charge. Owner notification letters are expected to be mailed September 26, 2023. Owners may contact Porsche's customer service at 1-800-767-7243. Porsche's number for this recall is APB1.
EV propulsion warning; power loss; high-voltage cable recall
A charging cable that overheats residential outlets at Porsche's factory-set 100% charge configuration poses a genuine fire risk — Porsche acknowledged this through a safety recall covering essentially all Cayenne E-Hybrid production years. If an owner received the replacement cable but the vehicle continued to exhibit charging interruptions or thermal warnings, that follow-on symptom may indicate the separate OBC/BMS issue (iss-17) and constitutes a new, uncured defect supporting an additional lemon-law claim.
Owners are advised not to use the 220V/240V compact/portable charging cable and only use the 110V home charging cable or public charging stations. Dealers will supply a new 220V/240V compact/portable charging cable with an incorporated temperature sensor, free of charge. Owner notification letters w
sticky steering; steering wheel feels stuck; increased steering effort; steering recall
A cracked front axle upper control arm can break suddenly, causing complete loss of front-wheel steering and wheel control — a Catastrophic-adjacent safety scenario. However, the root cause is a manufacturing defect (installed with pre-existing cracks) rather than an operational fire/fatality risk, making Safety the correct bin. 2024 Cayenne E-Hybrid owners should confirm the ARB2 replacement was performed and insist the repair order documents the part was verified crack-free post-installation.
Dealers will replace the driver side left upper control arm, free of charge. Owner letters were mailed September 13, 2024. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is ARB2.
engine stalls while driving; vehicle will not start; loss of power; fuel pump recall
A fuel leak from improperly tightened high-pressure fuel pump fasteners creates an under-hood fire risk — a well-established lemon-law priority defect under Song-Beverly. For Cayenne E-Hybrid owners, the 3.0L turbo V6 (and 4.0TT V8 in Turbo S E-Hybrid) both rely on the same high-pressure fuel system. Owners who noticed fuel smell, saw the check engine light, or had dealer inspections related to fuel-system odors before the ASA remedy should preserve those records as part of a potential claim.
Dealers will inspect and tighten the screw connections and replace the high pressure fuel pump and fuel lines as necessary, free of charge. Owner notification letters were mailed November 19, 2025. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is ASA
backup camera blank; screen goes black in reverse; rearview camera distorted
This broad fleet recall (covering 2019-2024 Cayenne E-Hybrid across all production years) demonstrates that Porsche's rearview camera software defect was persistent and not resolved by the earlier 2019 camera recall (iss-02). Owners who experienced repeated backup camera failures across multiple dealer visits between 2019 and 2025 — prior to the ASB2 remedy in early 2026 — have a documented multi-year repair-attempt history for the same safety system. That history is directly relevant to a Song-Beverly claim if the camera failures substantially impaired use during the warranty period.
Dealers will update the driver assistance software, free of charge. Owner notification letters were mailed February 13, 2026. Owners may contact Porsche customer service at 1-800-767-7243. Porsche's number for this recall is ASB2. Vehicle Identification Numbers (VINs) involved in this recall will be
PASM warning light on; ride height incorrect or vehicle leans; air suspension drops to lowest setting; compressor runs continuously; yellow or red suspension warning; car sits lower on one corner; rough ride on highway
An air suspension defect that persists across multiple dealer visits — even with each visit resulting in a different partial fix (software update, then compressor replacement) — counts as repeated attempts to repair the same defect under Song-Beverly. If the vehicle spent substantial time out of service across these visits, that independently supports a lemon-law claim. PHEV owners should document every visit where PASM was noted on the repair order.
PASM compressor inspection and duty-cycle fault code retrieval via PIWIS III; PASM control module software update; compressor replacement if duty-cycle DTC is active. Covered under Porsche warranty during warranty period; post-warranty cost is significant ($1,500-$3,000+ depending on extent).
charging interrupted mid-session; charger trips breaker; 240V cable warm or hot to touch; charge indicator never reaches 100%; 'Charging Interrupted' alert on PCM; charging cable smells warm; outdoor outlet or EVSE trips
Charging failure that prevents the vehicle from operating in its advertised EV mode constitutes a defect affecting use and value under Song-Beverly. If a dealer replaced the recall cable but the thermal cutoff persists due to the BMS calibration issue, the owner has documented a second, uncured defect — each shop visit strengthens the repeated-attempt count.
Recall 23V841 remedy: dealers supply a new 240V cable with integrated temperature sensor; owners advised to avoid 100% setting on non-dedicated circuits. For BMS-triggered cutoffs (non-cable): HV battery management software update via PIWIS III addresses threshold recalibration. Persistent cases may require OBC module inspection.
Service Hybrid System warning on dashboard; EV mode unavailable; car drives only on combustion engine; reduced performance warning; hybrid system limited operation message; yellow or orange hybrid warning light; PCM shows hybrid system fault
When the dealer cannot duplicate the warning and closes the repair order without a confirmed fix, that visit still counts as an attempt under Song-Beverly — a 'cannot duplicate' closure does not reset the counter. Owners should ensure the repair order specifically mentions the 'Service Hybrid System' complaint even if no fault codes are stored at time of visit.
BMS and hybrid control module software update via PIWIS III (first-line); if DTC P0A1F present, HV battery state-of-health evaluation required. Porsche covers BMS update under warranty; HV battery replacement is a warranty item within the 8-year/100,000-mile hybrid warranty.
vehicle will not start after sitting 2-3 days; 12V battery dead; need jump-start repeatedly; battery warning light; all electronics dead after short storage; battery tested OK but drains overnight; car won't wake up from sleep
A 12V drain that leaves the vehicle inoperable after brief parking constitutes a defect that substantially impairs use — a key Song-Beverly trigger. If the dealer replaces the 12V battery multiple times without applying the HV gateway software fix, each replacement is a distinct repair attempt. Owners should demand the repair order specifically note the HV gateway software update, not just a battery swap.
HV gateway module software update via PIWIS III; 12V AGM battery replacement if below recovery threshold; verify parasitic draw after 30-minute sleep. Covered under Porsche warranty; post-warranty 12V battery replacement is approximately $300-$500 at dealer.
harsh downshift at low speed; shudder when accelerating from stop; jerk when transitioning from electric to gas; hesitation on tip-in; rough engagement when braking lightly; transmission bangs into gear; torque surge on electric motor engagement
Transmission shudder and harsh shifting that recur after a TCM calibration update are among the most straightforward Drivability/Reliability lemon-law claims — each return for the same symptom adds to the repair-attempt count. Owners should use the exact language 'harsh shift' or 'shudder on electric-to-gas transition' on every repair order to ensure the visits are linked to the same defect.
TCM calibration update and hybrid drive unit software flash via PIWIS III. Verify smooth low-speed tip-in and brake-release after update. If harshness persists after software fix, valve body inspection may be warranted.
PCM screen freezes mid-drive; touchscreen unresponsive; navigation disappears; backup camera won't load through PCM; audio mutes spontaneously; PCM reboots unexpectedly; screen goes black while driving; voice command unresponsive; PCM takes 2+ minutes to boot
PCM failures that require three or more dealer software flashes for the same freeze symptom establish a repair pattern under Song-Beverly. On the Cayenne E-Hybrid, the PCM freeze also disables hybrid mode status displays — elevating the defect from a pure infotainment issue to one affecting the vehicle's PHEV functionality. Document each visit with the specific complaint and PCM software version installed.
PCM 6.0 software update delivered via dealer PIWIS III OBD flash. Hard-reset PCM after update and verify camera, audio, navigation, and hybrid display restoration. Units with repeated freeze after multiple software updates may require head unit replacement.
Level 2 charging fails to start; charge indicator light does not illuminate; 'Charging Interrupted' message on PCM; charging session stops after a few minutes; car shows not charging despite connected cable; J1772 inlet does not engage; charge stops before battery full
A Cayenne E-Hybrid that cannot reliably charge via Level 2 is unable to operate as a plug-in hybrid — the advertised PHEV capability is substantially impaired. California buyers paid a premium for EV functionality; persistent charging failure directly supports a Song-Beverly claim for defect substantially impairing use and value. Multiple no-fix service visits for the same charging fault build the required repair-attempt pattern.
OBC firmware update via PIWIS III (first-line); verify full Level 1 and Level 2 charge cycles post-update. If fault persists, OBC module hardware replacement required. Hardware replacement covered under Porsche warranty; post-warranty OBC replacement is a significant cost.
no sound from speakers; audio cuts in and out; Bose or Burmester system silent; audio works for a few minutes then stops; bass channel gone; treble only; system shows audio playing but no sound; audio lost after PCM reboot; surround sound disabled
Premium audio system failure on a $90,000+ vehicle constitutes a defect substantially affecting vehicle value under Song-Beverly. While audio loss alone rarely triggers lemon-law eligibility as a sole defect, when it occurs alongside other documented defects (PCM freeze, 12V drain, hybrid warnings), the cumulative repair-visit count across all defects can establish the substantial-impairment pattern. Each audio-related visit should be documented separately on its own repair order.
PCM audio amplifier firmware update via PIWIS III; test all channels after update. If audio loss persists, audio amplifier module replacement. Covered under Porsche warranty during warranty period.

Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act protects Cayenne E-Hybrid owners when a warranted defect is not repaired after a reasonable number of attempts, or the vehicle spends substantial time out of service for warranty repairs.
You may have a claim if: your backup camera failed repeatedly before Porsche's second recall (ASB2) finally addressed it — two recalls for the same defect pattern supports a multi-visit repair history; your 12V battery has died multiple times and dealers replaced the battery without applying the HV gateway software fix; the 'Service Hybrid System' warning returned after one or more dealer visits closed as 'no fault found'; or your vehicle spent 30 or more cumulative calendar days at the dealer across all warranty repairs.
Song-Beverly entitles you to a replacement vehicle or full repurchase — including down payment and monthly payments made. The manufacturer pays your attorney's fees if you prevail, so qualified lemon-law representation is typically available at no out-of-pocket cost to you.
Relevant warranty coverage: Porsche's 4-year/50,000-mile bumper-to-bumper warranty, plus an 8-year/100,000-mile HV battery warranty under California regulations. Defects that first appeared within the warranty period may still be pursued. General information only; not legal advice. Law as of Jun 30, 2026.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
The Cayenne E-Hybrid's most frustrating defects — 12V drain, hybrid warnings, PCM freeze, PASM faults, charging failures — are intermittent. Dealers routinely close repair orders as 'unable to duplicate.' Here is how to counter:
1. MEASURE THE PARASITIC DRAW. For 12V drain: ask the dealer to measure parasitic current after a 30-minute sleep cycle. PHEV spec is <50mA; excess draw is objectively measurable, not an opinion. Put this spec in writing when you drop off the car.
2. REQUEST PIWIS III HISTORICAL FAULT CODES. PIWIS III logs DTCs even after they self-clear. If the dealer says 'no codes,' demand the stored fault-code history — not just current codes. For 'Service Hybrid System' warnings, specifically request DTC P0A1F and HV gateway freeze-frame.
3. USE EXACT SYMPTOM LANGUAGE ON EVERY REPAIR ORDER. Write: 'backup camera does not display in reverse,' 'Service Hybrid System warning appeared on [date] at [mileage],' '12V battery discharged after X days parked,' 'harsh shudder on electric-to-gas transition,' 'Level 2 charging interrupted.' Vague entries ('electrical issue') let dealers link visits to separate defects.
4. VIDEO AND PHOTOGRAPH EVERY EVENT. Film PCM freeze with the odometer visible. Capture the charger status light and PCM 'Charging Interrupted' screen together. Phone timestamps are evidence.
5. TRACK EVERY OUT-OF-SERVICE DAY. Song-Beverly counts calendar days at the dealer for warranty repair. Parts back-orders on PASM compressors and HV battery diagnostics count. Request a loaner vehicle in writing.
6. PUT PORSCHE ON WRITTEN NOTICE. After two or more unresolved visits, send written notice to Porsche Cars North America before the next appointment. Retain proof of delivery.
The Porsche Cayenne E-Hybrid's fifteen-recall record across six model years tells a story of a complex plug-in hybrid platform that Porsche's warranty and recall infrastructure struggled to keep pace with. The two-recall sequence on rear axle trailing arm (21V271 + 22V040) and the six-year gap between rearview camera recalls (19V111 and 25V896) are the clearest indicators that some defects were not resolved on first attempt at the manufacturer level — before they even reached the individual owner's repair record. Add the PHEV-specific TSB issues that don't appear in recall data at all (12V drain, OBC charging failures, hybrid system warnings, PASM aggravation from battery weight), and this vehicle presents one of the richer lemon-law documentation opportunities in the Porsche lineup. Owners who kept repair orders are better positioned than they may realize.
— The Margarian Law team
If your Cayenne E-Hybrid has had repeated dealer visits for camera failure, 12V battery drain, hybrid system warnings, or charging failures, you may have options. Margarian Law has handled thousands of lemon-law cases and offers a free review of your repair orders — no obligation. A qualifying buyback or replacement comes with manufacturer-paid attorney fees.
The 'Service Hybrid System' warning on the Cayenne E-Hybrid (2019-2023) is frequently caused by an overly tight cell-voltage monitoring calibration in the early HV battery management software rather than a genuine battery failure. The BMS triggers protective warnings — and forces the vehicle into combustion-only mode — when battery cells are still within normal operating range. Porsche issued a technical service bulletin (TSB HV-SVC-WARN-2022-001) directing dealers to update the BMS and hybrid control module software via PIWIS III. If your dealer closed your repair order as 'no fault found' because the warning was not present at the time of inspection, insist they retrieve stored PIWIS III historical DTCs — particularly code P0A1F. If the warning recurs after a software update, request an HV battery state-of-health evaluation, which is covered under Porsche's 8-year/100,000-mile HV battery warranty. Multiple visits without a confirmed fix each count toward a potential lemon-law claim. []
The 12V auxiliary battery drain on the Cayenne E-Hybrid is a documented PHEV-specific defect. The hybrid control module's HV gateway stays partially active during vehicle sleep, drawing parasitic current that exceeds the 12V AGM battery's capacity to sustain — owners typically find the battery dead within 48-72 hours of parking even when the high-voltage battery is fully charged. Porsche issued TSB 12V-DRAIN-EHYBRID-2020-001 to address this: the fix is an HV gateway software update via PIWIS III to implement proper sleep-mode logic, followed by 12V battery replacement if the battery has been discharged below recovery threshold. If your dealer is only replacing the 12V battery without applying the HV gateway software update, the parasitic draw will continue to drain each new battery. Ask specifically for the gateway software update on your repair order. Repeated 12V battery deaths that require jump-starts are a defect substantially impairing vehicle use under California Song-Beverly law. []
No — these are two separate defects, and understanding the distinction matters for repair documentation. NHTSA Recall 23V841 (remedy ARS9) covers the 220V/240V portable compact charging cable: the cable itself lacks an adequate thermal sensor, causing it to overheat residential outlets when used at 100% charge. The remedy is a replacement cable with an integrated temperature sensor. Separately, a TSB documents on-board charger (OBC) module failures that prevent Level 2 J1772 charging sessions from initiating or completing — presenting as 'Charging Interrupted' even with known-good charging equipment. If you received the replacement cable under the recall but your Cayenne E-Hybrid still will not charge, the OBC module is likely the cause. That is a distinct, uncured defect requiring firmware update or hardware replacement. Document each charging failure on a separate repair order so the two defects are tracked independently. []
Yes. Under California's Song-Beverly Consumer Warranty Act, a 'cannot duplicate' or 'no fault found' dealer closure does not prevent that visit from counting as a repair attempt — it is still a warranty service call for the documented complaint. For the Cayenne E-Hybrid, the most common cannot-duplicate scenarios involve the 'Service Hybrid System' warning, PCM screen freeze, and 12V battery drain, all of which are intermittent by nature. To protect your claim: use specific complaint language on every repair order (not 'electrical issue' — use exact symptoms such as '12V battery discharged after 3 days parked' or 'Service Hybrid System warning appeared on highway'); ask the dealer to retrieve PIWIS III historical DTC logs before closing the repair order; and document the odometer reading, date, and any verbal statements from service advisors. Each visit where you report the defect and the dealer performs any inspection — even concluding they found nothing — is a documented attempt. If you have three or more such visits, or if the vehicle has spent 30+ days at the dealer, consult a lemon-law attorney. []
There are actually two separate NHTSA recalls for rearview camera failure on the Cayenne E-Hybrid, issued six years apart. NHTSA Recall 19V111 (remedy AKA0, 2019) addressed a software delay causing the backup camera image to be late or absent for 2019 model year vehicles. NHTSA Recall 25V896 (remedy ASB2, notified February 2026) covers a broader failure — the rearview camera image does not display at all when the vehicle is placed in reverse — across 2019-2024 Cayenne and Cayenne E-Hybrid. If your camera has been failing repeatedly between 2019 and 2025 and you did not receive the ASB2 remedy, contact Porsche customer service at 1-800-767-7243 using Porsche recall reference ASB2. Additionally, if your PCM 6.0 screen freezes while driving, the camera display may fail as a consequence of the PCM freeze — a related but distinct TSB issue that requires a separate PCM software update. Document both issues separately on repair orders. []
The Cayenne E-Hybrid rear axle issue began with NHTSA Recall 21V271 (remedy AMA9), which addressed stress-corrosion cracking in the rear trailing arm lock nut on 2021 model year vehicles. The cracking could allow the rear axle alignment to shift unexpectedly, creating a handling safety risk. Porsche directed dealers to replace the lock nuts. However, Porsche then discovered that dealers were not consistently verifying rear axle alignment after performing the lock nut replacement — leaving some vehicles with misaligned rear axles after the supposed fix. This triggered a second recall, 22V040 (remedy ANA1, 2022), requiring dealers to inspect alignment, correct it if needed, and replace prematurely worn tires caused by the misalignment. For 2021 Cayenne E-Hybrid owners: if you had the AMA9 repair but experienced unusual tire wear afterward, the ANA1 alignment check may not have been completed. Both repair visits count as separate attempts under Song-Beverly. Contact Porsche at 1-800-767-7243 and reference both AMA9 and ANA1 to confirm your VIN's status. []
