FUEL/PROPULSION SYSTEM
On July 14, 2026, I experienced a serious fuel system failure with my 2023 GMC Denali. That morning, I filled the vehicle with a little over 20 gallons of fuel at a gas station approximately two miles from my home. Later in the day, I made a short trip to my neighborhood swimming pool, roughly 1.5 miles round trip, with no unusual noises or warnings from the vehicle. Approximately two hours after returning home, I entered the vehicle to run an errand. When I shifted into reverse and began backing out of my carport, I immediately heard a scraping noise on the concrete. I stopped the vehicle and inspected underneath. At that point, I discovered that the entire fuel tank had fallen out of the vehicle and was resting on the ground. I contacted roadside assistance, and the vehicle was towed to the dealership. The dealership informed me that the fuel tank support straps were missing, which allowed the tank to detach and fall. I personally searched along all the routes I had driven earlier that day and did not locate any straps or debris. The tank itself showed no impact damage, suggesting it dropped cleanly rather than being torn loose by road contact. Although the vehicle is relatively new, my bumper to bumper warranty expired in September 2025, and I was charged for the repair. I have included photos taken before and during the tow, as well as the dealership’s invoice. I am extremely concerned about the safety implications of this failure. If the tank had fallen while I was driving at interstate speeds (approximately 70 mph), it could have caused a catastrophic fire hazard, loss of vehicle control, or danger to other motorists. I do not know how long the vehicle had been operating without fuel tank straps, nor why there were no warnings or indications of a structural issue. I also question why the dealership did not treat this as a manufacturing or assembly defect, given that fuel tank straps should not detach under normal use. ...RAN OUT OF CHARACTERS...

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
The car just died while going 55mph on the highway. Complete shutdown but luckily both the steering and brakes worked. After stopping it wouldn’t start again. I had my three children in the car aged [XXX], [XXX], and [XXX]. It was a horrific experience. GMC did some repairs to the engine that took over two months and then the car had a few more warnings pop up just a few weeks later. GMC now says there is a misfiring in one of the positions. I’m terrified of driving this car with my children as I don’t know when it will shut off again and how bad it will be!

Engine seized while driving on the highway. This is the same engine that is being recalled and GM has said that the vin is not covered. The vehicle stopped running on a major highway with my [XXX] old son in the car. The dealership is saying this is the exact issue that is part of the larger investigation for GM v8 engines. There were no warning lights at all prior to the engine seizing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We're in the waiting period for our 3rd engine. 1st engine failure, while driving on interstate at 70+ MPH, engine stopped running, causing a very unsafe condition for family and surrounding vehicles. Engine failure 2 days later, towed to dealership for inspection, replacement engine was installed ~4 weeks later. 2nd engine failure, while driving on interstate at 75+ MPH, engine seemed underpowered and would rev upwards of 6000+RPMs, not exactly unsafe, but not usual operating conditions either. Returned to dealer, upon inspection, total engine replacement was recommended.

ENGINE, FUEL/PROPULSION SYSTEM
The engine in my 2022 GMC Yukon XL equipped with the 6.2L L87 V8 experienced a sudden loss of power while traveling at interstate speed. The vehicle had previously received the GM L87 engine recall remedy. Despite the recall being completed, the engine failed, leaving me and my family in a dangerous situation. The vehicle is currently at a GMC dealership and is available for inspection upon request. The sudden loss of engine power on a busy interstate created an immediate safety hazard. Traffic was traveling at highway speeds, and the vehicle rapidly lost the ability to maintain speed, increasing the risk of being struck from behind or being involved in a serious collision. My family was in the vehicle at the time, making the incident especially concerning. The GMC dealership has confirmed that the engine failure is related to the L87 engine issue and advised that the repairs will be covered under the applicable warranty/recall-related coverage. Additionally, after the original recall service was performed, an expanded recall was added to my VIN, further indicating that the original remedy may not have fully addressed the underlying defect. The vehicle is currently being inspected by the authorized GMC dealership. Prior to the engine failure, there were no warning signs indicating an imminent catastrophic failure. The recall service had already been completed, leading me to believe the vehicle was safe to operate. The engine nevertheless failed after the recall remedy, raising concerns that the corrective action may not be sufficient to prevent future failures

POWER TRAIN, ENGINE, ELECTRICAL SYSTEM
While driving about 70 mph in the express lanes, the vehicle suddenly lost power and drifted like it went into neutral. There were no warning symbols. The vehicle could not restart even while coasting. After stopping, it locked itself in park and would not shift out of park. My family and I were trapped on the express lanes for over an hour in a dangerous location. The vehicle stayed stuck in park even on the tow truck. The dealer confirmed metal in the oil filter, a blown main fuse, and knocking when starting. The recall inspection and remedy were already done, but the failure still happened. The vehicle is undriveable and the required recall repair cannot be completed because the replacement engine is on backorder with no ETA.

ENGINE AND ENGINE COOLING
The contact owns a 2021 GMC Yukon XL. The contact stated that while driving 55 MPH, several unknown warning lights illuminated, and the check engine warning light started blinking. The contact pulled over and became aware that the vehicle was shaking. The vehicle was turned off and restarted; however, the failure persisted, with smoke coming from the vehicle. The vehicle was repaired under NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); but the repair failed to fix the vehicle. The vehicle was taken to the dealer, where it was diagnosed, and it was determined that the camshaft needed to be replaced and that cylinder #8 was damaged and had detached. The manufacturer was notified of the failure. The failure mileage was 116,204.

The infotainment screen on my 2021 GMC Yukon was previously replaced at the GMC dealership, and this will be my second replacement. It has now cracked even though there was only very light contact. This doesn’t seem like normal wear and tear. I’d really appreciate it if the screen could be inspected, as I suspect there might be a manufacturing issue with these screens. I’m quite concerned about this problem because it almost caused injury to my six-year-old. Please understand my worries, I’m sure many other parents are facing similar concerns with these screens. The cracked glass can be dangerous, especially for families with children.

FUEL/PROPULSION SYSTEM
My 2021 GMC Yukon XL recently suffered a failure of its fuel pump control module. This occurred at just 44,000 miles, mere weeks after my manufacturer warranty expired in June of 2026. This issue goes far beyond a financial inconvenience or a matter of consumer reimbursement; it is a severe, life-threatening safety hazard that GM has failed to permanently resolve. My Experience: Sudden Power Loss While Towing The gravity of this part failure became clear during a recent drive. I configuration-matched this vehicle—a heavy-duty Yukon XL with a 6.2L engine and a 4x4 towing package—specifically for its capacity to safely haul heavy loads. While traveling with a trailer attached, the vehicle experienced a sudden, catastrophic loss of engine power. Without warning, the engine sputtered and died. Had this occurred on a steep incline, a blind curve, or in heavy highway traffic, a catastrophic multi-vehicle collision would have been entirely unavoidable. Critical Safety Hazards and Concerns •Inability to Maintain Speed, Loss of Vital Assist Systems, & Compounded Towing Risks Systemic Failure and Inadequate Remediation What makes this situation entirely unacceptable is that this specific vehicle was already subject to previous GM safety campaigns regarding this exact component (including Safety Recall #N212332040 and subsequent Emission Recall #N252516900). GM is fully aware that their supplier produced defective modules that are prone to premature internal short-circuits. Yet, their remediation strategy has been entirely inadequate. By managing this through piecemeal, phased rollouts and limited VIN inclusion lists, they are leaving dangerous vehicles on the road until the point of failure. Drivers are effectively acting as crash test dummies, waiting for their engines to die in dangerous environments before GM acknowledges that their specific VIN was fitted with the defective supplier part.

ENGINE, POWER TRAIN
Issue Description: The vehicle experienced a failure of the Dynamic Fuel Management (DFM) system, resulting in a collapsed lifter. This caused a cylinder misfire and a sudden loss of engine power while driving at highway speeds. Safety Concern: While traveling at highway speeds, the sudden misfire and loss of power created a dangerous condition. The vehicle could not maintain speed or accelerate properly with surrounding traffic, significantly increasing the risk of a collision. Failure Details: The issue was diagnosed as a collapsed lifter related to the DFM system. This caused persistent misfiring, rough engine operation, and severe drivability issues. Repair Outcome: Due to the extent of internal engine damage caused by the lifter failure, the vehicle required complete engine replacement.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS, UNKNOWN OR OTHER
On [XXX] brake system failure, service ESC, Forward Collision system unavailable and check engine lights came on the dashboard and the vehicle had no brakes. Taken to dealership and Conley GMC advised the Main Module was burnt out. $1200.00. Car was “fixed” and sent out. The next morning all the check engine light along with all other failure lights came on after module was replaced. Taken back to dealership and they advised that everything had to be manually programmed which was done and sent out. [XXX] same dashboard errors were up again. Taken back to dealership and they advised they needed to reprogram manually that was done and sent out. The next morning all lights were back on. It was the weekend so they wouldn’t take the car or provide a rental. May 23rd car was taken back to dealership and Conley advised the master cylinder was bad and had to order parts. $4300.00 in repair cost along with 2.5 week at the dealership and $150.00 in rental cost. I found online that GM knew of this issue with the 2022 GMC Yukon XL vehicles and a recall was made however this vehicle VIN number was not included in this recall. I notified Conley GMC and they stated they were not informed of this issue. I made a claim with GM and told them of this issue and my safety concerns and they advised that because this was not included in the recall that there was nothing they could do and they would not be covering financial assistance or reimbursement and they called this an inconvenience instead of a real safety issue as each time my vehicle had no working brakes. No working brakes causes safety concerns for everyone in the vehicle as well as other vehicles. All work orders are at Conley Buick GMC in Bradenton, Fl.

ELECTRICAL SYSTEM
The large central infotainment touchscreen (which controls climate control/AC, navigation/maps, audio, backup camera, and all primary vehicle functions) has repeatedly failed by going completely dark/blank without warning on my 2026 GMC Yukon Denali XL purchased new on [XXX]. The screen has gone dark on three separate occasions. First failure occurred prior to [XXX]; vehicle was taken to Champion GMC (7885 W Grand River Rd, Brighton, MI 48114) for repair and returned to me. The screen failed again shortly after. Second repair attempt was made on 06/22/2026; vehicle was returned and the screen failed again immediately. The vehicle is currently at Champion GMC for a third repair attempt as of 06/29/2026. Safety risk: Loss of the screen eliminates access to the backup/rearview camera, speedometer display, climate controls (heat and AC), navigation, and warning indicators — all while operating the vehicle. There is no warning, message, or dashboard indicator prior to each failure. The screen goes dark suddenly and without notice. The problem has been confirmed and repair attempted three times by Champion GMC. The vehicle has not been inspected by police or insurance representatives. The component is available for inspection upon request, as the vehicle is currently at the dealership INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
