STRUCTURE:BODY
The vehicle was parked and turned off for approximately 45 minutes on a residential street along the curb in front of a house when the rear window suddenly shattered. I was inside a nearby house at the time. A landscaper working in the area reported hearing a single loud pop and then my vehicle’s alarm sounding. He stated he was not close to the vehicle and did not see any object strike it. When I inspected the Yukon, the entire rear window had exploded outward and inward, leaving no glass remaining in place. Glass was scattered both inside the cargo area and outside behind the vehicle. The upper liftgate section had also popped open, which is consistent with the sudden pressure release that occurs during spontaneous tempered‑glass failure. There are no impact marks, dents, or paint damage that would indicate a rock strike or external force. Given the circumstances, the debris pattern, and the absence of an impact point, this appears to be a spontaneous failure of the tempered liftgate glass, likely due to internal stress or a manufacturing defect. I am requesting that the dealership inspect the liftgate assembly, confirm the cause, and consider warranty coverage for the glass replacement and any related components.

SERVICE BRAKES, ELECTRICAL SYSTEM, POWER TRAIN
On June 25, 2026 my 2023 GMC Yukon Denali with 53,456 miles was brought to an authorized GMC dealership after displaying a Service 4WD warning light and exhibiting a groaning noise when shifting into Drive and Reverse. The vehicle was diagnosed with the following brake system fault codes: P25A2, C0511, C0517, C1595 and C1596. These codes indicate brake control module failure and wheel speed sensor faults which are safety critical components. The dealership confirmed these findings but stated the repairs are not covered under the GMC powertrain warranty. Given that these are safety critical brake system failures on a nearly new vehicle with only 53,456 miles, we contacted GMC Customer Care on July 1, 2026 to request coverage under goodwill warranty as we believe these failures constitute a manufacturing defect. A case was opened however after 7 days no case advisor has been assigned and no decision has been made despite two promised timelines not being met. The brake system failures on a nearly new vehicle represent a serious safety concern as these systems directly affect the vehicle's ability to stop safely. The vehicle has been at the dealership since June 25, 2026 and remains unrepaired.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
As I was driving the automatic emergency brakes went off and stopped me so hard and fast that I feel like I got whiplash. The seatbelt yanked me backwards, smacking my head against the headrest, I have an instant headache from it and my neck and shoulder still hurt 20 minutes later. It scared me and my child half to death, my heart was pounding and I could have been rear ended. I was driving about 40mph and was in no way in any harm/needing to break (specially this hard) for anything when this happened. This is not the first time my car has unnecessarily automatically slowed down quickly but this is the first time it’s ever been this abrupt and severe. I will be taking my car to be inspected for this issue and if my neck and shoulder still hurt in the next day or two, I will also be going to the doctor about the incident.

ENGINE AND ENGINE COOLING
The contact owns a 2022 Chevrolet Yukon. The contact stated that while driving at an undisclosed speed, an abnormal knocking and ticking sound emanated from the engine before the vehicle stalled. The vehicle was towed to a local dealer, where it was diagnosed with total engine failure, requiring replacement. The vehicle was not yet repaired. The contact stated that the current engine was a replacement engine from a previous failure, which was tested prior to installation but also failed. Additionally, the contact stated after the failure, the transmission could not be shifted into Neutral, forcing the tow operator to drag the vehicle onto the flatbed truck. The manufacturer was not yet notified of the latest failure. The failure mileage was 45,000.

ENGINE
My 2022 GMC Yukon (6.2L L87 V8, VIN [XXX]) is covered by recall 25V-274 / GM N252494000, "L87 Engine Loss of Propulsion." In May 2025, at about 65,800 miles, the engine lost power and shut down while I was driving, then developed a loud knocking noise and an intermittent low-oil-pressure warning. The dealer (The Faricy Boys Automotive, Salida, CO) found excessive metal in the oil sample and replaced the entire engine under this recall in June 2025. The original engine serial was [XXX]; the replacement serial is [XXX]. On XXX, at about 93,000 miles — roughly 27,000 miles after the recall repair — the REPLACEMENT engine GM installed began making the same knocking noise. A dealer (Turner Automotive, Montrose, CO) has confirmed the engine is failing and has ordered a second replacement engine. The recall remedy GM performed did not fix the defect; the engine GM installed to cure the recall is now exhibiting the same failure mode (knocking / loss of propulsion). When the engine failed on XXX, GM Roadside Assistance refused to cover towing despite the engine's replacement coverage, and I had to pay roughly $484 out of pocket to tow the vehicle about 74 miles to the nearest dealer. This is a safety issue: the defect causes loss of motive power, and in my first failure the vehicle shut down while I was driving. I am reporting this because the recall remedy itself appears defective, consistent with NHTSA Recall Query RQ26001 regarding the adequacy of the remedy for campaign 25V-274. Please associate this report with that recall and that investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, ENGINE
The contact owns a 2023 GMC Yukon. While the contact's wife was driving approximately 5-10 MPH on a city street and approaching a stop sign, the vehicle experienced a failure and became inoperable. The contact stated that while the driver was attempting to restart the vehicle, the battery warning light and engine warning light illuminated, and the "Low Battery - Start Engine" message was displayed. The vehicle was towed directly to a dealer to be diagnosed. The dealer was unable to determine the cause of the failure but provided an estimate for the valve springs inspection. The vehicle was not repaired. The manufacturer was notified of the failure and was working with the dealer to determine how to repair the vehicle. The failure mileage was approximately 71,481.

VISIBILITY/WIPER
The vehicle is equipped with “rain-sensing windshield wipers” but they do not work due to poor design. They should not have failed this quickly (33,000 or so miles). The windshield wipers must be manually activated because of this defect, but since the manufacturer thought they would be automatic, they made the manual activation very hard to access. It is very dangerous trying to activate them while operating the vehicle because A) your eyes are off the road for an extended period in poor conditions and B) the control is in a hard-to-reach area. You have to turn the nob 6-7 positions to put the wipers on low or high, and for the first 5 positions the windshield wipers don’t activate.

SEAT BELTS, ELECTRICAL SYSTEM, EXTERIOR LIGHTING
The panoramic sunroof has a substantial leak, even though the 2023 vehicle only has 33,000 miles on it. The drain lines are clear but water continues to significantly leak out of the rear passenger seatbelt housing onto the seatbelt. There is also significant water drainage through the rear interior lights onto the upper legs of rear passengers (children in car seats), causing a severe electrical hazard. The leaking caused by the drainage defect affects the interior lighting, the seatbelts, and is a potential electric hazard. This seems to be a common occurrence and the manufacturer should repair their defective products. The drainage pipes are obviously either not assembled correctly or the materials don’t hold up. This should not be occurring in a $55,000 vehicle with 30,000 miles. I have multiple videos I can provide but the file sizes are too large to upload, so I took screenshots. I am going to pay for the repair but I should be reimbursed by GMC.

ENGINE
My car started making a knocking noise under the hood 2 days prior to it breaking down (6/19 & 6/20). On 6/21/26, I was driving down the interstate WITH my kids in the car and it shut down on its own. Lights came on my dash and the vehicle quickly slowed itself down and when I pulled over to a complete stop, the vehicle shifted into neutral and shut off. I was not able to crank it back up and had to pay a tow company $243 out of pocket to tow it to our local dealership in town. My insurance only covers $200 for towing. I am a week without a vehicle and just found out Friday (6/26) that a new motor will have to be ordered but it is on back order with no idea on when it may arrive. I cannot get an answer from GM or my local dealership on if a rental will be provided. I cannot make 2 car payments but I also have a job and cannot proceed without having a vehicle to drive. This has put me in a bind for a week already with no solution in sight. I expect GM to fix my problem asap since it is theirs to fix!!

ELECTRICAL SYSTEM
The center screen (infotainment), which shows controls for cabin climate (A/C, heat) and many more functions of the vehicle fails to turn on at random times. It is available for inspection. The external air temperature is in the upper 90s; temperature inside the car’s cabin is easily 115 or higher. This makes safe operation of the car not possible. Additionally passengers cannot occupy the vehicle safely at these extreme temperatures. The problem has been reproduced by dealers. UNKNOWN whether the components have been inspected by the manufacturer. No warning lamps or lights.

ENGINE
This truck has the 6.2 GM engine. While driving it late at night at approximately 28mph the engine blew, leaving the truck in the lane and unable to move. This was very dangerous since there was no warning and it just died. The truck receives regular maintenance by GMC and was tested to see if it was a “bad engine” and we were instructed that it wasn’t. GM said it will take 4-8 weeks to get an engine and the value of the truck to trade in is very low due to “marketing issues” which in my opinion is their issue not mine. I am battling stage 4 cancer and just had an operation and need a car to go to the doctors. They have officially said that they don’t have a truck to loan me. This has been going on for years apparently and the government is not doing anything to rectify it for the US tax payers per my research. I need a truck and GM said that they would get back to me within 24-48 hours, we are way past that. What is the government going to do, these trucks are not safe. What if I was traveling late at night to snowmobiling and it blew, it would be a different story. Need some help

POWER TRAIN, FUEL/PROPULSION SYSTEM, ENGINE
Engine overheated and performed an emergency shutdown while driving through Atlanta on my way to vacation with my family. We lost propulsion and had to cross 5 lanes of traffic to find a shoulder to pull over to. The engine shut down and we were left stranded 500 miles from home with our 3 children in a boiling car. The vehicle was inspected and passed the recall test 6 weeks prior to this incident. After the first failure we attempted to extend our power train warranty to which we were told it had too many miles by GM. The GM dealership and service center where the vehicle was towed confirmed the engine needed to be replaced and GM confirmed it falls under their extended warranty. However, GM refuses to cover any additional expenses incurred from their engine failure.

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 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.
