2020-2026 Defender: DC-DC power loss, airbag risk, engine fire, Pivi Pro blackout. CA lemon law may entitle you to a buyback. Free review.
You paid six figures for a Land Rover Defender. The badge promises capability, prestige, and a vehicle that takes you anywhere without compromise. Instead, many 2020-2026 Defender owners have found themselves stranded — not on a trail, but on the freeway — when the mild-hybrid (MHEV) system cuts all drive power without warning. If that has happened to you, you are not alone, and you may not have to keep living with it.
The L663 Defender entered the U.S. market in 2020 as a modern, technology-laden reimagining of an iconic nameplate. It carries Jaguar Land Rover's Ingenium engines, a 48-volt mild-hybrid system (MHEV) on most trims, and the Pivi Pro infotainment platform. All three of those systems have been the subject of confirmed NHTSA recalls affecting every model year from 2020 through 2026. In total, the Defender L663 has accumulated at least nine NHTSA recall campaigns since launch — covering electrical propulsion failure, engine oil fire risk, airbag non-deployment, rearview camera blackouts, engine stalls, and a defective fuel tank on brand-new 2026 units.
California law — the Song-Beverly Consumer Warranty Act — gives you rights when your vehicle cannot be repaired after a reasonable number of attempts. For Defender owners dealing with unresolved safety recalls, repeated dealer visits, or a vehicle sitting at the dealership while Land Rover develops a remedy that does not yet exist, those rights may be worth exploring.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
Vehicle suddenly loses all drive power while moving; exterior lights go out; 12-volt system fails to charge; dashboard warning lights; vehicle stranded without warning
Open recall with no remedy as of filing date — a vehicle that loses all drive power without warning and cannot be repaired presents a strong substantial-impairment and reasonable-number-of-attempts argument. MHEV buyers who have suffered repeat stalls or been unable to get a remedy may have ripe claims.
Remedy under development as of Jun 28, 2026; interim owner notification mailed June 17, 2026; no repair currently available
Airbag warning light illuminated; driver airbag may not deploy in a crash; SRS fault codes
Entire model-year range 2020-2026 affected. Airbag non-deployment is a safety-critical defect; combined with no final remedy available, this supports lemon-law claims for any Defender owner whose airbag warning light has not been resolved or who received only the interim lubricant treatment.
Interim remedy: dealers apply protective lubricant gel to connector terminals; final remedy not yet available as of Jun 28, 2026
Oil leak onto hot engine or exhaust components; burning smell; smoke from engine bay; oil warning light; fire risk
Two separate NHTSA fire-risk recalls on the engine oil system affect consecutive model years (2020-2024 combined). Owners who suffered oil leaks, return visits, or unremedied fire risk have strong multi-visit claims. 2023-2024 owners may have been subject to both recalls.
23V044000: inspect/replace engine cam carrier and related components. 24V450000: replace oil filter housing, filter, and o-rings.
Center touchscreen goes dark or stays blank when vehicle starts; rearview camera image not visible; infotainment system freezes or reboots during driving; Pivi Pro system unresponsive
Pivi Pro infotainment instability is one of the most widely reported owner grievances on the L663 Defender. NHTSA confirmed a formal recall (25V016000) for the blank-screen/FMVSS 111 violation. Owners with repeated infotainment failures, multiple dealer visits, and ongoing software updates that fail to fully resolve issues present strong lemon-law candidates — particularly where the system controls critical safety functions (reverse camera, ADAS displays).
Dealers update touchscreen software (25V016000 remedy); broader Pivi Pro instability complaints addressed by progressive OTA/dealer software updates
3D surround-view camera stops working; rearview backup camera image does not display; camera system warning on Pivi Pro screen
Second independent FMVSS 111 violation on the Defender platform (alongside 25V016000). 2024 model year owners may face both camera-system recalls simultaneously.
Dealers replace the NFSM
Engine shuts off unexpectedly while driving at speed; no warning before stall; vehicle loses power and coasts; may not restart immediately
Engine stall while driving is a per-se safety defect and a strong lemon-law trigger. 2020-2021 buyers who experienced unexpected stalls, particularly those who required multiple dealer visits before the OTA/dealer fix was applied, have viable claims.
Connected Diagnostic Services and OTA diagnostics functionality disabled via dealer visit or OTA update (21V424000 remedy)
Brake lights, tail lights, and turn signals stop working; rear lights fail to illuminate; warning light on dashboard; other drivers cannot see vehicle
Complete rear lighting failure while driving is a safety defect affecting visibility to other drivers. Defender X trim buyers with this issue who experienced repeat light failures or multiple dealer visits have viable lemon-law grounds.
Dealers replace rear light assemblies
No pre-crash symptom; risk of fuel leak and fire if vehicle is in a collision
Manufacturing defect on brand-new 2026 model year. Owners who were sold a vehicle with a defective fuel tank and required a dealer tank replacement before the vehicle performed as warranted have a strong new-vehicle lemon-law argument.
Dealers replace the fuel tank
12-volt charging warning; 'Stop Safely Electrical Fault Detected' or similar dashboard message; sudden loss of drive power while driving; exterior lights go out; vehicle fails to keep 12-volt system charged at start-up
Open recall with no final remedy: a mild-hybrid vehicle that can lose all drive power and exterior lighting without warning presents a strong substantial-impairment argument under Song-Beverly. Because this is the second DC-DC converter campaign on this vehicle line in five months (26V248 in April 2026, 26V599 in September 2026), a California owner with prior converter or 12-volt charging complaints, repeat dealer visits, or extended out-of-service time while awaiting a remedy has a well-documented repair-attempt record; each visit for the same power-loss condition counts toward the reasonable-number-of-attempts threshold.
Software update (load balancing, start-up stability fix, protective limp-home mode); final remedy not yet available as of Sep 30, 2026, interim letters expected November 13, 2026
open
The DC-DC converter may malfunction due to an electrical overload during high power demand, and a software error can cause the converter to stop functioning at vehicle start-up. Failure of the DC-DC converter results in loss of 12-volt system charging and can lead to complete loss of drive power and exterior lighting. Companion campaign to 26V248: covers later-specification (phase 2) MHEV DC-DC converters and excludes vehicles already in recalls D126/H575.
open
The driver's air bag clockspring connector may corrode, which can cause the air bag not to deploy as intended.
closed
The fuel tank was improperly manufactured with walls that are too thin.
open
The DC-DC converter can fail due to an internal fault in the boost control microchip. A failure of the DC-DC converter will result in a loss of 12-Volt system charging and can lead to complete loss of drive power and exterior lighting.
closed
The touchscreen in the center console may go blank at vehicle startup, resulting in the rearview camera image not displaying as intended. Fails to comply with FMVSS No. 111 Rear Visibility.
closed
The Near Field Sensing Module (NFSM) may overheat and cause the 3D surround camera images, including the rearview camera image, not to display. FMVSS No. 111 Rear Visibility violation.
closed
The oil filter housing can crack and leak oil into the engine compartment.
closed
The engine cam carrier oil channel may be blocked, which can lead to an oil leak.
closed
Driver and front passenger seat belt pretensioners may be damaged, preventing proper occupant restraint.
closed
The seat belt automatic locking retractors may deactivate early, which can prevent the child restraint system from securing properly.
closed
A voltage spike, triggered by a bright light shining on the rear of the vehicle, can cause the turn signals, brake lights, and tail lights to fail.
closed
The Powertrain Control Module (PCM) may unexpectedly switch off while the vehicle is in motion, resulting in an engine stall with no warning.
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 — often called the lemon law — applies to new and certain used vehicles purchased or leased in California that come with a manufacturer's warranty. If your Land Rover Defender has a defect that substantially impairs its use, value, or safety, and the manufacturer or its authorized dealers have been unable to repair that defect after a reasonable number of attempts, you may qualify for a repurchase, replacement, or cash settlement.
A 'reasonable number of attempts' is not fixed at a specific number. For safety defects — like loss of drive power at highway speed, an airbag that may not deploy, or engine fire risk — California law can presume a lemon with fewer visits than a non-safety defect. The law also recognizes situations where your vehicle has been out of service for 30 or more cumulative calendar days.
Importantly, if Land Rover has issued a recall but no remedy is available, you may not need to wait indefinitely. The absence of a repair after notification of a safety defect is itself relevant to a lemon-law analysis.
Under Song-Beverly, if your claim succeeds, you are entitled to have your attorney's fees paid by the manufacturer — meaning you typically do not pay out of pocket to pursue a claim. This is a general summary only and does not constitute legal advice. Whether your specific situation qualifies depends on the facts of your case.
“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.
If your dealer tells you they cannot reproduce your Defender's problem, do not accept that as the end of the road. Here is what to do:
1. Document every symptom the moment it happens. Photos, videos, screenshots of warning messages on the Pivi Pro, and the date and mileage at the time. Even a short phone video of a dark screen or a warning cluster is evidence.
2. Request a repair order for every visit, even if the dealer says they 'found nothing.' The date, mileage, and complaint description on that repair order are the foundation of a lemon-law claim. Ask the service advisor to write your complaint exactly as you describe it.
3. Check NHTSA's recall database at nhtsa.gov/recalls for your VIN. Several Defender defects — including the DC-DC converter failure and the airbag clockspring recall — have no available remedy yet. If your vehicle has an open recall with no fix, document that the dealer acknowledged the recall but could not complete a repair.
4. Note the intermittent nature. Electrical faults and Pivi Pro software failures are often intermittent by design. 'Could not duplicate on inspection date' does not mean the defect does not exist — NHTSA confirms these defects through complaint data and formal recall filings.
5. Track out-of-service days. California law considers cumulative days without a functioning vehicle. Every day your Defender is at the dealer — or every day you are told parts are not yet available — counts.
6. Request loaner or rental documentation. Land Rover's obligation to provide alternate transportation during extended repairs is relevant to your claim.
The L663 Defender has accumulated a recall record that is difficult to explain for a vehicle at its price point. Two separate open recalls with no available remedy as of June 2026 — one for complete loss of drive power, one for potential airbag non-deployment — represent an unusual situation: Land Rover has officially acknowledged these safety defects exist, notified owners, and then told them there is currently nothing a dealer can do to fix the vehicle.
For owners in that position, the question of whether California lemon law applies is worth a genuine legal analysis. The cases that tend to be most straightforward are ones where the defect is confirmed by a recall, the repair history documents multiple visits, and the remedy remains unavailable — all three of which apply to a meaningful number of current Defender owners.

If your 2020-2024 Defender MHEV (mild-hybrid) has lost all drive power while moving, the most likely cause is a DC-DC converter failure covered by NHTSA Recall 26V248. A microchip fault inside the DC-DC converter can cut the 12-volt charging system, causing the entire drivetrain to shut down without warning. As of June 2026, Land Rover has notified owners of the defect but does not yet have a repair available. If this has happened to you more than once, or if your dealer has been unable to complete the recall repair because no parts are available, that situation may support a California lemon-law claim.
Yes. NHTSA Recall 26V389, issued June 2026, covers 2020-2026 Land Rover Defenders. Moisture can corrode the driver's airbag clockspring connector terminals, potentially preventing the frontal airbag from deploying in a crash. If your airbag warning light is on or you have received a recall notice, bring the vehicle to a Land Rover dealer. Note that as of June 2026 only an interim remedy (lubricant gel applied to the connector) is available — a permanent fix is still under development. If your airbag light has returned after the interim treatment, document that visit.
For 2023 and 2024 model year Defenders, yes — NHTSA Recall 25V016 specifically covers a software defect in the Pivi Pro system that causes the touchscreen to go blank at vehicle startup, blocking the rearview camera image required by federal law (FMVSS 111). The remedy is a dealer software update. A separate recall (NHTSA 24V678) covers the Near Field Sensing Module overheating and disabling the surround and backup camera system on 2024 models. Owners of other model years who experience repeated Pivi Pro freezes, reboots, or unresponsive screens should document each dealer visit, as software defects that require multiple repair attempts can contribute to a lemon-law claim.
The Defender has been subject to two separate NHTSA fire-risk recalls affecting the engine oil system. NHTSA Recall 23V044 (2020-2023 models) covers a blocked cam carrier oil channel that can cause an oil leak near ignition sources. NHTSA Recall 24V450 (2023-2024 models) covers a cracking oil filter housing with the same fire hazard consequence. Additionally, 2026 Defender owners are subject to NHTSA Recall 26V263, which covers fuel tanks manufactured with walls too thin to withstand a collision without leaking fuel. If you smelled burning, saw smoke from the engine bay, or noticed an oil warning light, bring the vehicle in and reference these recall numbers.
California's Song-Beverly Consumer Warranty Act may entitle you to a vehicle repurchase, replacement, or cash settlement if your Defender has a defect that substantially impairs its use, value, or safety and has not been repaired after a reasonable number of attempts under warranty. The Defender's documented recall history — including two open recalls with no available remedy as of June 2026 — is relevant context. Whether your specific situation qualifies depends on your repair history, the nature of the defect, and your warranty status. A lemon-law evaluation is typically free, and if your claim succeeds, the law requires the manufacturer to pay your attorney's fees.
An unexpected engine stall while driving — where the Defender shuts off with no warning at speed — was the subject of NHTSA Recall 21V424, which covers 2020 and 2021 Defenders with six-cylinder engines. A software defect in the Powertrain Control Module (PCM) can cause it to shut down while the vehicle is in motion. After a stall event: note the exact date, mileage, speed, and road conditions; bring the vehicle to a dealer with a written description of the event; ask the service advisor to check for open recalls by VIN; and keep every repair order. If the stall has happened more than once, or if the dealer's response was 'could not duplicate,' that documentation may be important for a potential lemon-law claim.
