POWER TRAIN, ENGINE
I was driving home on the interstate from vacation and I was set on cruise control it was 1 am so not a lot of traffic was on the road thank god. It could have been really terrible if lots of traffic was present as the engine just died without notice! The vehicle was decelerating nothing was working I could not speed up. I was able to get over to the side of the road. I got a notification on my phone that said battery critically low start vehicle to charge battery. Well nothing would start at this point. I lot all power seconds later. I thought that the cruise control was locked up and restarting it would reset it. I called roadside assistance to get a jump and that did not work. I got towed into an auto repair shop. They called me and told me that the engine is locked up that they drained the oil and found metal in it and metal pieces in the oil filter as well. They checked for leaks and said there was none that they could find. They said there was a recall but it was for the exact same symptoms that was diagnosed here but only starting with year 2021. Mine is a 2019 Yukon Denali with low mileage so not sure if all the other Yukons were aged out or already past engine death and that’s why they were not part of this but this should be included in with the open recall considering how everything is the same that is effecting this year that I have and they should pay for a new engine! Clearly the v8 6.2 gmc engines are having major issues I’m just glad I wasn’t going that fast and traffic was slow so I was able to get over safely before catastrophic things happened since there was no warning when this all happened!

AIR BAGS, ELECTRICAL SYSTEM, SEATS
The driver's seat inboard airbag assembly and internal structural wiring harness failed due to a direct short circuit, completely deactivating the vehicle's supplemental restraint system. General Motors has a known engineering bulletin for this issue (#23-NA-085), noting that sharp internal seat frame components slice the airbag wiring harness. Rather than permanently fixing this structural design flaw while under warranty, dealership technicians repeatedly executed temporary, non-compliant field patches, including plastic zip-ties and Velcro tape inside the cushion. These temporary patches continuously failed, leaving the airbags disabled. Furthermore, the vehicle was sold under "Certified Pre-Owned" designation with an active, uncompleted 2020 manufacturer Customer Satisfaction Program Campaign (#N202310850-02) for this exact airbag circuit defect. Component failed & available for inspection: The driver's seat inboard airbag assembly and internal structural wiring harness failed due to a direct short circuit. The components are available for inspection inside the vehicle at the servicing dealership. Safety risk: Safety was put at extreme risk because active Diagnostic Trouble Code B14DC completely deactivates the airbags. This means the airbags may fail to deploy in a collision, leaving the driver completely unprotected in an accident. Confirmed by dealer: The problem has been explicitly reproduced and confirmed by an authorized franchise dealership across seven separate service visits spanning from August 2025 to June 2026. Inspected by manufacturer/others: The components have been physically inspected multiple times by authorized franchise dealership technicians acting on behalf of the manufacturer. Warning lamps & symptoms: The vehicle displays "Service Safety Restraint System" warning message on the dashboard. The warning lamp first appeared on August 26, 2025, at 78,472 miles while the vehicle was strictly within its CPO warranty

ENGINE
engine failure causing vehicle to be unsafe to drive. our vehicle was not included in the L-87 loss of propulsion GMC recall even though it is a 2021 Yukon 6.2L. the engine failure is same as those being recalled. vehicle is currently at Cardinale GMC in Seaside CA waiting repair. the only warning of the impending failure was loud noises coming from engine compartment while driving on the freeway. Cardinale confirmed the problem and our extended warranty is covering repair costs. it seems that GMC should have included our VIN in the recall.

ELECTRICAL SYSTEM, POWER TRAIN
with no warning ,the GMC 6.2L engine failed on my family trip to Colorado. The engine seized at HWY speeds, stopped running, failed to restart and had to be towed to local dealer. This issue is a known GMC defect with numerous reports and a safety recall issue. I was fortunate to be able to move offer in hwy traffic and get to the shoulder where my situation took 8 hours travel time to continue my family trip.

ENGINE, POWER TRAIN
With no warning, my engine 6.2 L stopped running at highway speeds and failed to restart. The power train completely failed for a second time after having a previous engine replaced for the same failure in 2024. I had the car inspected per the recall along with changes in the oil viscosity as recommended along with service inspection. The car left me stranded again on rural highway for over 5 hours in temps that exceeded 98 degrees. The car would not start and went into a power save shutdown and had to be towed to the dealer. I was fortunate to have avoided any traffic on the highway enough to get the car off the road. This is not safe to drive on the highway and GMC has known defect and safety concern with this issue.

VISIBILITY/WIPER, UNKNOWN OR OTHER
On multiple occasions the center screen has been non operational when we start the car and just shows a black screen. The volume knob and screen power button are non-responsive. When this occurs the backup camera is inoperable, which is mandatory safety equipment. the HVAC also cannot be adjusted which could cause a windshield fogging condition which is a safety concern. The vehicle has been to the dealer 3 times for screen problems and the issue has not been resolved. When this occurs the problem persists for a few ignition cycles or for up to a couple of days and then will start functioning again. We have not been able to determine any specific condition that is causing the failure.

SERVICE BRAKES
The recall repair for the brake vacuum pump did not hold for this vehicle. Even after the repair, several years later, the brakes would get hard as a rock, especially at low speeds and there was difficult stopping the vehicle. Due to the special Warranty on this recall, I was able to get the brake vacuum pump replaced at no cost. However, the recall repair failed initially. This is a safety issue.

AIR BAGS
1. Component / System Failed: The Supplemental Restraint System (SRS) / Driver’s Inboard Seat Airbag circuit has chronically failed, leaving the vehicle's primary safety restraint systems disabled. The faulty components and the physical service records documenting the failure are fully available for inspection upon request. 2. Safety Risk: The driver's safety and the safety of passengers are put at extreme, immediate risk. Whenever this failure occurs, the "Service Safety Restraint System" warning illuminates, which completely disables the airbag deployment system. Driving a heavy passenger vehicle (2021 GMC Yukon) without active driver-side airbag protection leaves the operator exposed to severe injury or fatality in the event of a collision. 3. Dealer Confirmation / Reproduction: The problem has been reproduced, diagnosed, and confirmed by an authorized dealership (Quirk GMC in Manchester, NH) on five separate occasions spanning from August 2025 to June 2026. 4. Inspections: The component has been repeatedly inspected by the manufacturer’s authorized dealer technicians at Quirk GMC. It has not yet been inspected by police or insurance representatives, as no crash has occurred. 5. Warning Lamps / Symptoms: The failure is preceded by the "Service Safety Restraint System" dashboard warning lamp and message illuminating. This symptom first appeared in August 2025 at 78,472 miles and has continuously reappeared shortly after every subsequent repair attempt made by the dealership, indicating a continuous, unresolved defect in the vehicle's safety manufacturing or a severe failure in the manufacturer's diagnostic repair procedures.
