Fuel Supply Line Improper Attachment — Fire Risk Recall 21V422 (2021)
warning light; recall notice; repeated dealer repair
Catastrophic2021
OPEN HOURS MON–FRI | 9AM–6PM
2020-2026 Cadillac XT6 has 12 NHTSA recalls covering transmission, fuel, airbag, and camera defects. California owners may qualify for a refund or replacement. Free case review.
You paid a premium for three rows, a luxury badge, and the peace of mind that comes with a Cadillac. The XT6 — GM's answer to the Acura MDX and Lincoln Aviator — promised a refined, technology-forward crossover that could carry your family in comfort and keep them safe. For many owners, that promise has held. But for a significant number, the XT6's six-year production run has been shadowed by a set of defects that no luxury buyer should encounter: a nine-speed transmission that shudders and lurches during ordinary acceleration, an airbag system recalled in the very first model year, fuel lines that can separate and risk fire, and a rearview camera so prone to failure that NHTSA launched a probe before GM issued a recall. Twelve formal NHTSA recall campaigns span the 2020-2025 model years — an unusually high number for a single nameplate in a six-year window. The defects range from a fuel tank rollover valve that won't seal in a crash, to a 2023 transmission sun gear that can literally separate from the half-shaft and leave the vehicle rolling away in a parking lot. Owners of the early LGX 3.6L V6 models have reported timing chain rattle and oil consumption; later LSY 2.0T buyers have encountered fuel pump control module failures that cut the engine without warning in live traffic. Across all years, the automatic emergency braking system has been documented under a preliminary information bulletin — not a full recall — that GM has revised at least six times through 2025 without a durable fix. If you are an XT6 owner who has made repeated dealer visits for any of these issues, California's Song-Beverly Consumer Warranty Act may give you the right to a replacement vehicle or a full refund. Understanding what went wrong — and documenting it correctly — is the first step.
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.
airbag warning light; passenger airbag may not deploy; SRS warning; occupant detection fault
A defect in the roof-rail airbag inflator that may degrade curtain performance in a side collision directly impairs occupant safety — the core standard for Song-Beverly lemon-law eligibility. If a dealer performed the recall repair (RRAB module replacement) but documented a return visit for the same airbag system warning or incomplete remedy, that pattern supports a lemon claim. The 2020 MY scope means owners who purchased the vehicle new have been living with this risk since launch.
GM will notify owners, and dealers will replace the suspect RRAB modules, free of charge. The recall began September 3, 2020. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-333-4223, or Buick customer service at 1-800-521-7300. GM's number for thi
engine stalls while driving; vehicle will not start; loss of power; fuel pump recall
An engine stall caused by a manufacturing burr in the fuel pump jet nozzle creates a sudden loss of motive power — a safety defect under Song-Beverly whether or not the vehicle has been involved in a crash. If the recall remedy was delayed due to parts unavailability (documented in multiple 2020-2021 owner complaints), the out-of-service days during that wait period count toward the 30-day cumulative threshold under California law.
GM will notify owners, and dealers will replace the fuel pump module. The recall began November 16, 2020. Owners may contact GMC customer service at 1-888-988-7267, Buick Customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.
transmission shifts unexpectedly; hesitation; harsh shift; transmission warning
Missing bolts in the start-stop accumulator can cause sudden transmission fluid loss and immediate loss of vehicle propulsion — a safety defect. The 2019-2020 scope captures all first-year XT6 buyers. Owners who experienced a loss-of-drive event before the recall remedy was available, and who visited the dealer without a permanent fix, may have accrued qualifying repair attempts under Song-Beverly's lemon presumption.
GM will notify owners, and dealers will inspect the start-stop transmission accumulator and replace it if any bolts are missing, free of charge. The recall began December 15, 2020. Owners may contact GMC customer service at 1-888-988-7267, Buick Customer service at 1-866-608-8080, Chevrolet customer
warning light; recall notice; repeated dealer repair
A fuel supply line that can separate and leak fuel creates a fire risk — placing this firmly in Song-Beverly's safety and health impairment standard. Owners of 2021 XT6 models with this recall should confirm the remedy was performed; any dealer visit documenting the open recall or incomplete repair extends the out-of-service calculation and may support an expedited buyback request citing fire risk.
Dealers will inspect and replace fuel supply lines as necessary, free of charge. Owner notification letters were mailed on July 1, 2021. Owners may contact Cadillac customer service at 1-800-458-8006 and GMC customer service at 1-800-462-8782. GM's number for this recall is N212335590.
brake pedal problem; reduced braking; unexpected braking; brake warning light
Missing brake fluid reservoir warning label is a federal safety-standard compliance defect (FMVSS 135), but its practical impact on vehicle use is low absent actual brake fluid contamination. Under Song-Beverly, this recall alone is unlikely to anchor a lemon claim, but combined with other 2022 XT6 defects documented in the same period, it forms part of the overall repair-visit history relevant to the lemon presumption.
Dealers will inspect the brake fluid reservoir cap and replace it, if necessary, free of charge. Owner notification letters were mailed June 30, 2022. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is N222369130.
front suspension noise; stabilizer bar loose; vehicle pulls or clunks
A toe link that separates can cause sudden and unpredictable handling changes at any speed — a loss-of-control safety defect under Song-Beverly. Owners who experienced unusual rear-end handling or steering pull before the recall was announced may have made dealer visits that were misdiagnosed; those visits should be reviewed as potential qualifying repair attempts for the toe-link defect.
Dealers will inspect the left-rear suspension and replace the fastener if it is loose or missing, free of charge. Owner notification letters were mailed July 11, 2022. Owners may contact Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recal
fuel smell; fuel leak; reduced fuel range; fuel filler or fuel tank recall
A fuel tank rollover valve that fails to seal during a rollover crash creates a fuel-spill and fire hazard — Song-Beverly's highest-priority safety category. If GM cannot confirm completion of the remedy (fuel tank replacement where valve is dislodged or missing), the vehicle remains in a defective condition. Owners who experienced fuel odor or difficulty filling the tank before the recall should review those dealer visits as potential qualifying events.
Dealers will inspect the fuel tank and replace the fuel tank shell if the rollover valve is found to be dislodged or missing, free of charge. Owner notification letters were mailed July 27, 2022. Owners may contact Cadillac customer service at 1-800-458-8006 and GMC customer service at 1-800-462-878
warning light; recall notice; repeated dealer repair
An illegible tire-pressure certification label is a federal compliance defect (FMVSS) but does not, on its own, substantially impair the vehicle's use, value, or safety under Song-Beverly. This recall is most relevant as part of a broader repair history that, combined with other powertrain or safety defects on the same 2023 XT6, may meet the lemon presumption threshold.
Dealers will replace the vehicle certification label, free of charge. Owner notification letters were mailed October 12, 2022. Owners may contact Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N222381690.
backup camera blank; screen goes black in reverse; rearview camera distorted
Federal law requires a functioning rearview camera on vehicles sold from 2018 onward; a camera that fails intermittently or completely creates a real rear-visibility hazard. If a 2020-2021 XT6 owner had the camera recall repaired but the camera continued to fail (documented in multiple post-repair NHTSA complaints), each return visit for camera failure counts as a separate repair attempt toward Song-Beverly's lemon presumption.
Dealers will replace the coaxial cables, free of charge. Owner notification letters were mailed January 18, 2023. Owners may contact Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N222378380.
transmission shifts unexpectedly; hesitation; harsh shift; transmission warning
Half-shaft disengagement from the transmission causes sudden loss of drive power and creates a vehicle-rollaway risk when parked — both are clear safety impairments under Song-Beverly. The 2023 model year scope means buyers of new XT6s experienced this defect within their first model year. Owners who placed the vehicle in park without applying the manual parking brake before the recall remedy was available may have faced rollaway risk; any dealer visit related to sudden power loss or grinding noise should be preserved.
Dealers will replace the sun gears, free of charge. Owner notification letters were mailed on July 27, 2023. The remedy is expected to become available August 31, 2023. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer servi
warning light; recall notice; repeated dealer repair
A windshield that is not properly bonded to the vehicle body can detach during a crash, increasing occupant ejection risk and degrading airbag performance — a critical safety defect. 2024 XT6 owners who noticed wind noise or water intrusion before the recall was announced should document those dealer visits; they may constitute qualifying repair attempts if the condition was present but not correctly diagnosed.
Dealers will inspect the windshield and apply primer and urethane sealant. If the windshield is damaged, the dealer will replace it. Repairs will be performed free of charge. Owner notification letters were mailed November 14, 2023. Owners may contact Cadillac customer service at 1-800-458-8006 or G
warning light; recall notice; repeated dealer repair
Failure of turn signal, high-beam, and hazard warning indicator lights violates FMVSS 101 and 108, and creates a practical safety concern for driver situational awareness. Under Song-Beverly, an instrument cluster that requires a software update and continues to malfunction after the update constitutes a recurring defect. Owners whose instrument cluster also went blank — a more severe symptom reported in 2024 NHTSA complaints — face a stronger safety impairment argument.
Dealers will update the instrument panel software, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact Cadillac's customer service at 1-800-458-8006. GM's number for this recall is N242447940.
Shudder or shake at 40-60 mph during acceleration; lurching jerk on 1-2 upshift; 5th-9th gears locked out intermittently; high-pitched whine on deceleration; flashing 'D' on gear indicator; transmission fluid leak; loss of drive momentarily after shift
Under Song-Beverly, a recurring transmission shudder or gear-engagement failure requiring multiple dealer visits qualifies as a defect substantially impairing use, value, or safety. If the dealer performs a fluid service under TSB 23-NA-072 and symptoms return within normal use, each repeat visit with the same complaint code counts toward the presumption. Owners should retain all repair orders with transmission-related DTCs and request documentation of any fluid-change or torque-converter replacement.
TSB 23-NA-072: GDS2 diagnosis, ATF drain/refill with specified fluid; if TCC damage confirmed, replace torque converter. Early 2020-2021 units with 9T65 hardware issues: full transmission unit replacement per discontinued pilot program.
Rattling or ticking noise on cold start that diminishes after warm-up; check engine light with timing-related codes (P0008, P0009, P0016, P0017); engine rough idle after cold soak; excessive oil consumption (quart or more per 1,000 miles); oil level over-full dipstick reading from condensation in short-trip driving
Song-Beverly covers engine defects that substantially impair use or value. An LGX timing chain tensioner failure producing check-engine codes, rough running, or oil-starvation risk at highway speed may support a lemon claim if the dealer cannot achieve a durable repair after two or more attempts. Owners should record each repair order citing timing chain or oil-consumption diagnosis, and note whether GM's goodwill replacement criteria were triggered.
TSB 19-NA-070: inspect and replace timing chain tensioners as needed; for oil consumption, per GM bulletin 01-06-01-011Q: document oil loss across defined interval and replace valve stem seals or short-block as warranted.
Engine cuts out suddenly at speed without warning; check engine light with fuel system DTCs; delayed or hard starting; vehicle stalls in traffic or at intersections; FPCM found failed at 20,000-40,000 miles; dealer documents 'known GM issue'
An engine stall without warning at highway speed is a safety-impairing defect under Song-Beverly regardless of whether a formal recall has been issued at the time of the repair. Owners who experienced stall events and returned to the dealer two or more times before the 2025 FPCM recall may have a claim based on those prior repair attempts. Backorder delays that extend the vehicle's out-of-service period also count toward Song-Beverly's 30-day cumulative out-of-service threshold.
Replace fuel pump power control module; GM dealers may require part to be on backorder (documented owner complaints about extended waits). 2025 recall remedy: FPCM replacement at no charge.
Center touchscreen goes completely black while driving; display freezes and requires dealer or manual reboot; audio stops playing in cold weather; key-detected chime absent; speedometer or instrument cluster blanks out simultaneously; screen reboot cycle repeats after short interval
Infotainment failure may seem minor, but when the display also controls navigation, backup camera output, and vehicle alerts, Song-Beverly's 'use and value' standard can encompass repeated display failures. If a software update fails to durably resolve the issue and the owner returns two or more times within 18 months, a lemon claim becomes viable for this defect alone or in combination with other issues.
TSB 21-NA-188: radio software update V158 (OTA or dealer-applied). If display unit itself has failed, replace display module. Soft reset (hold power/mute button) as temporary workaround.
Automatic emergency braking activates abruptly with no obstacle present; 'Forward Collision System Reduced' or 'Service Driver Assist' message on DIC; amber AEB Disable icon illuminates; adaptive cruise control disengages unexpectedly; near-collision events from false ADAS braking while backing or at highway speed
Unexpected autonomous braking that causes or nearly causes a collision is a safety defect under Song-Beverly regardless of whether NHTSA has escalated to a formal recall. The persistent PIT5551 bulletin revisions spanning 2020-2025 without resolution indicate GM has not achieved a durable fix — multiple dealer visits for the same ADAS complaint strengthen a lemon-law argument substantially.
Clean front radar sensor; if condition persists replace radar module (~$600); reprogram ADAS control module. Some owners report recurrence after repair.

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 — the state's lemon law — applies to any new vehicle purchased or leased in California that has a defect the manufacturer is unable to repair after a reasonable number of attempts. For the Cadillac XT6, the law is directly relevant to several documented defects.
The Song-Beverly Act creates a rebuttable presumption that a vehicle is a lemon if: (a) the same defect has been subject to repair four or more times within the first 18 months or 18,000 miles, or (b) the vehicle has been out of service for 30 or more cumulative days during that same window. The 18-month and 18,000-mile thresholds are not a hard cutoff — defects that appear later can still qualify if the manufacturer has had a reasonable number of attempts to fix them.
For XT6 owners, qualifying defects may include:
If your XT6 qualifies, GM must offer you a choice: a comparable replacement vehicle or a full refund of the purchase price (minus a reasonable offset for mileage driven before the first repair attempt for the defect). The manufacturer is also responsible for paying your attorney's fees if you prevail — which means a qualified lemon-law attorney can typically represent you at no out-of-pocket cost.
Preserve every repair order, recall notice, and service communication. If GM has told you the vehicle is repaired and the same problem returned, that conversation should be documented in writing.
“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 most frustrating phrase any XT6 owner hears at the service counter is: 'We drove it and couldn't reproduce the problem.' Here is how to build a record that makes that defense impossible.
1. Capture the symptom with your phone. Transmission shudder and AEB phantom braking are intermittent; a short video of the event — dashboard, speedometer, and all — gives the dealer's technician an objective record that cannot be dismissed as owner perception. Upload the video to a cloud service and note the date, time, speed, and road conditions in the file name.
2. Ask the dealer to pull all DTCs — stored, pending, and history. The XT6's 9-speed transmission, fuel system, and ADAS modules log fault codes even when the symptom is intermittent. Request a printed DTC readout with every service visit. If the dealer says 'no codes found,' ask them to document that in writing on the repair order.
3. Request open-recall status in writing. All twelve NHTSA recall campaigns for the XT6 should be disclosed at each service visit. If a recall remedy was not performed, ask the advisor to note the reason (parts unavailability, owner declined, etc.) on the repair order. Parts-backorder delays count toward your Song-Beverly out-of-service accumulation.
4. Insist on a GDS2 test drive for transmission complaints. TSB 23-NA-072 requires a specific scan-tool-monitored driving maneuver (0-30 mph launch at 15-20% throttle) to capture ISS oscillation data. If the dealer is not performing this protocol, they are not diagnosing the issue per GM's own published procedure. Ask them to note the diagnostic method used.
5. For the Forward Collision / AEB concern, ask the dealer specifically about PIT5551. This is a 'Preliminary Information' bulletin, not a standard TSB, and some dealers may not proactively look for it. Asking by bulletin number forces the technician to acknowledge the documented issue.
6. Track calendar days out of service. California's Song-Beverly Act creates a rebuttable presumption of lemon status after 30 or more cumulative days out of service. Keep a simple log: date dropped off, date picked up, reason. Loaner vehicles do not reset the clock.
Twelve recall campaigns in six model years is a significant record for any vehicle, and the Cadillac XT6 has not earned that distinction through bad luck. The recall map reveals systemic quality lapses across multiple systems — fuel delivery (three separate campaigns), airbags, camera hardware, transmission components, and instrument electronics. The 9-speed transmission shudder, meanwhile, has never been formally recalled despite being the single most-reported owner complaint across every model year. GM's decision to address it through a series of TSBs and a short-lived pilot replacement program, rather than a recall, means thousands of owners have navigated that repair process without the notification rights a recall would have provided. The AEB phantom-braking bulletin, still in 'preliminary information' status after five years and six revisions, is perhaps the most telling detail: GM cannot yet tell its own dealers how to definitively fix a safety-critical driver assist system on a vehicle it continues to sell. For buyers in the used-vehicle market, the 2020-2021 models carry the most recall exposure. For owners already living with these issues, California law provides a meaningful remedy.
— The Margarian Law team
If your Cadillac XT6 has been to the dealer multiple times for transmission shudder, engine stall, camera failure, or any of the issues covered by NHTSA's twelve recall campaigns — and the problem keeps coming back — you may have options under California's lemon law. Margarian Law has handled thousands of lemon-law cases across every major automaker and offers a free case review. There is no out-of-pocket cost if we take your case.
The most common cause is Torque Converter Clutch (TCC) shudder in the 9-speed automatic transmission, documented in GM Technical Service Bulletin 23-NA-072 (replacing earlier bulletin PIP5608J). The shudder typically occurs between 40-60 mph during the 4th-5th gear upshift or under steady throttle in 8th-9th gear. GM's diagnosis requires a GDS2 scan tool monitoring Input Shaft Speed oscillations during a controlled 0-30 mph drive. Depending on severity — categorized as Normal, Degraded, or Damaged — the remedy is either a transmission fluid drain/refill with specified ATF, or full torque converter replacement. On early 2020-2021 models with the 9T65-designated unit, GM ran a separate transmission-replacement pilot program that has since ended. If you have had the fluid changed and the shudder returned, request a second repair and document each attempt carefully — recurring transmission problems that resist repair are among the strongest lemon-law grounds under California's Song-Beverly Act.
Yes. NHTSA Recall 22V709 (campaign 22V709000) covers 2020-2021 Cadillac XT6 models equipped with the optional Surround Vision system. The defect: coaxial cable connectors for the rearview camera were improperly crimped at the factory, causing the camera to fail intermittently or completely in reverse. GM dealers replace the affected coaxial cables at no charge under the recall. NHTSA opened an investigation (PE22006) before the recall was issued, based on owner complaints documenting blank screens with a red X or warning triangle in reverse. If your vehicle had the recall repair performed and the camera is still failing, that is a recurrence — each dealer visit for the same camera issue after the recall repair is a separate qualifying repair attempt under California's Song-Beverly lemon law. Request a printed repair order for each visit and note the NHTSA complaint number in your records.
This is called phantom or false AEB (Automatic Emergency Braking) activation, and it has been a documented issue across all 2020-2025 XT6 model years. GM's internal bulletin PIT5551 — most recently revised as PIT5551R in April 2025 — identifies the front radar sensor as the likely culprit: contamination, moisture, or internal module degradation can cause the Forward Collision Alert system to trigger braking with no obstacle present. The bulletin has been a 'Preliminary Information' document for its entire five-year existence, meaning GM has not issued a definitive diagnostic or repair procedure. Dealers typically clean the sensor face first; if the condition persists, the radar module itself (~$600 part) may be replaced. However, recurrence after repair is reported. Unexpected autonomous braking creates a collision risk from following vehicles and may constitute a safety defect — the most protected category under California's Song-Beverly Act — even without a formal recall.
Engine stall on the XT6 has two separate causes that owners and dealers sometimes conflate. The first is covered by Recall 20V639 (2020 MY): a manufacturing burr in the low-pressure fuel pump's jet nozzle that can block fuel delivery, causing a sudden stall. The second — which affects 2020-2024 models across both LGX V6 and LSY 2.0T powertrains — is fuel pump control module (FPCM) failure. The FPCM is a separate electronic component that commands fuel flow; when it fails, the engine cuts out without warning, often in traffic. Multiple owners and dealer technicians have described this as a 'known GM issue.' GM issued a recall covering FPCM failure on multiple Cadillac models including the XT6 in 2025; owners with prior stall events that were misdiagnosed or unrepaired should review those records. Under Song-Beverly, an engine stall creating a traffic safety hazard qualifies for the expedited two-repair lemon presumption for safety defects.
Yes — the 2022 Cadillac XT6 has a fuel system recall (22V446) covering the fuel tank rollover valve on AWD models. The valve may not properly seal during a rollover crash, allowing fuel to leak and creating a fire risk. Dealers inspect the fuel tank and replace the tank shell if the rollover valve is found dislodged or missing, at no charge. The 2022 XT6 also carries two other recall campaigns: 22V392 (missing brake fluid reservoir warning label) and 22V427 (improperly torqued left-rear suspension toe link that can separate and cause loss of control). Together, three recalls on the 2022 model year means any owner making dealer visits during that period has repair-order documentation that could support a Song-Beverly lemon claim if combined with other recurring defects. Check your VIN at nhtsa.gov to confirm which campaigns have been remedied on your specific vehicle.
California's Song-Beverly Consumer Warranty Act entitles you to a replacement vehicle or a full purchase-price refund (minus a mileage offset) if GM cannot repair a defect after a reasonable number of attempts. The law creates a rebuttable presumption that your XT6 is a lemon if the same defect has been repaired four or more times within the first 18 months or 18,000 miles, or if the vehicle has been out of service for 30 or more cumulative days. For safety defects — such as engine stall, unintended AEB activation, or a transmission that causes sudden power loss — the standard drops to two repair attempts before the presumption applies. The XT6's documented recall and TSB record across transmission, fuel, camera, and ADAS systems means many owners may already meet these thresholds without realizing it. A free case review with a Song-Beverly attorney costs nothing: if your case proceeds, GM is required to pay attorney fees when you prevail. Gather every repair order, recall notice, and loaner-vehicle record before your consultation.
