VISIBILITY/WIPER, SEATS
1.The driver side mirror tilts up or down every time the vehicle is started requiring readjustment before driving. My wife was almost hit by oncoming traffic when she did not remember to readjust the mirror before merging with traffic. 2. The driver seat bolster inflates every time the vehicle is started. The vehicle cannot be driven without deflating the bolster. These have been reported to the dealer 3 months ago with no resolution from them or GMC.

Drove vehicle to town and back, 20 mile round trip. When entering my property, the Engine stalled while pulling into driveway. Upon cranking, was very hard to start. When taking the next trip after engine stall, vehicle died in motion at 60mph approaching a traffic intersection with no warning, leaving very little time to navigate to the shoulder and off the roadway. Engine will not crank over, suspect Engine has failed again, currently at dealer awaiting diagnostics. No lights, warnings, noises or indications of Engine failure were observed during the drive cycle.

FUEL/PROPULSION SYSTEM, ENGINE
My vehicle was one of the vehicles that was subject to the engine failure recall by GM. I took it to the dealership for the “repair“ where I was told the oil was changed to a different weight. Last night, I was driving down the road and all of a sudden my car just stopped. It still had power, but the engine had stopped. I tried to restart was unable to.

I towed it to the GMC dealership, they confirmed the engine is seized, but they have been very secretive, they did not tell me whats wrong, they been some what ignoring me, I dont have a car its been few days, no one reached out to tell me whats happening, no offer to give me a loaner, when I kept bugging me they said we're opening the enigne to send the broken part inside to the GMC headquarters, I asked to know what's the issue what's happening but I'm worried they will do another short cut, I need your help on what to do next

ENGINE, ELECTRICAL SYSTEM, SERVICE BRAKES
2023 Yukon Denali XL 6.2l: GM oil change recall performed (October 2025) and GMC dealership noted no issues. Prior to recall oil change, at aprox 5k miles interval (45K total miles), check engine oil light on dash and was over 1 quart low. Next oil change at aprox 50K miles, no check engine light came on, but certified mechanic drained and measure oil level, 1.5 quarts low. Engine often sounds odd at cold start, ticking sound. Now an oil change is $100 more, due to special oil, but not compensated for extra cost. Brake calibers failed. February 2026, engine light on, then off, then hood latch dash light warning now on and off. Huge safety concerns with the 2023 GMC Yukon 6.2L.

ENGINE
I was on the interstate and when I was passing a vehicle in the middle lane the engine lost power, shifted to N. I tried going back to drive it would not shift. Stopped the suv and tried restarting it. When I pushed on the brake and tried to start it the whole vehicle would loose power to all my screens. I had this vehicle towed in back in September 2025 due to not cranking over when starting. They did the recall for the engine at that time. The engine light would randomly turn on but would go back off within the same day.

ENGINE, UNKNOWN OR OTHER
POST-RECALL 25V274 ( & EA25007, EA25001) EXHAUST INTRUSION WITH CARBON MONOXIDE POISONING HAZARD Following the complete engine replacement under GM recall N252494000, my vehicle has developed a severe and persistent exhaust intrusion that allows toxic exhaust fumes, including carbon monoxide (CO), to enter the passenger cabin. CO levels have measured a peak of 83 PPM and consistent reading between 20-37 over multiple tests. PATTERN OF POST-RECALL EXHAUST SYSTEM FAILURES Vehicle has been in for service 6 times, over 100 days, as part of the engine replacement plus (metal found in the oil pan). Since recall, the vehicle has had an exhaust smell and noise rattle issue with the following exhaust system components deemed failed and been replaced: 1. Radiator cap (leaking onto exhaust) 2. Exhaust muffler (replaced TWICE - June 2025 and August 2025) 3. Exhaust clamps (leaking) 4. Left exhaust manifold (warped) Critical Finding: Despite replacement of virtually the entire exhaust system, the defect persists. This suggests a fundamental design or installation defect related to the engine replacement procedure, NOT isolated component failures. Documented Carbon Monoxide Levels: Between January 30 and February 3, 2026, I conducted 15+ tests using a professional-grade Klein Tools ET180 Carbon Monoxide Meter. Results: • Peak reading: 83 PPM • Multiple readings: 40-72 PPM sustained for 6+ minutes directly at my [XXX] daughter's car seat position • Testing method: Vehicle started via remote start, CO meter placed in cabin, readings recorded over 10-15 minute periods Health Impacts to Family: • Wife and [XXX] daughter consistently experience dizziness, headaches, and nausea when riding in vehicle • Daughter now refuses to ride in vehicle because it makes her feel sick • Symptoms consistent with carbon monoxide poisoning Independent service station verification on January 30th confirmed "vehicle is dangerous to operate with children inside and needs immediate service."

On 12/22/2025 I took my 2023 GMC Yukon in for the L87 recall. After receiving information that my vehicle passed the recall they told me that the oil would be change to from OW-20 to OW-40 and that my oil changes would go up in price (double the price) due to the oil being a high performance oil. On 01/05/26 exactly two weeks and 616 miles later our engine and lights completely stopped working while driving it on the road!!! The vehicle would not start or switch into neutral so we could get the vehicle off the road due to blocking traffic! The vehicle was towed the GMC dealership and had to have a new engine replacement. We were out of our vehicle for 31 days. Now our vehicle rear view camera guidelines have stopped working and now have to put that under warranty claim.

ENGINE
On two separate occasions, while driving at approximately 60 mph on New York parkways, my vehicle unexpectedly shifted into neutral and lost power without warning. During the first incident, a message appeared instructing me to “press start to continue.” I was able to restart the vehicle and drive home. Two days later, the same failure occurred again under similar conditions. This time, after pulling over and pressing the start button, the vehicle shut off completely and became totally inoperable. The vehicle had no power and would not restart. At the time of this second incident: - I had my [XXX] child in the vehicle - The outside temperature was approximately 20 degrees - Recent snow made it difficult to pull fully off the parkway - Police assistance was required to ensure our safety - We waited nearly two hours for a tow truck due to the hazardous roadside conditions This situation was frightening, dangerous, and completely unacceptable in a modern vehicle with approximately 24,000 miles. When GMC evaluated the vehicle the following day, I was informed that it requires a full engine replacement. A catastrophic engine failure at this mileage — combined with repeated, sudden loss of power at highway speeds — represents a serious safety defect that substantially impairs the use, value, and safety of the vehicle.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
Following a catastrophic engine failure in my 2023 GMC Yukon XL Denali, I discovered that the vehicle could not be shifted into neutral once the engine failed. This prevented the vehicle from being moved out of traffic if it had stopped in an active lane. The inability to place the vehicle into neutral after a loss-of-power event creates a serious safety hazard, particularly on high-speed roadways. In the event of a failure occurring in traffic, occupants may be left stranded in a travel lane with no ability to push or reposition the vehicle, significantly increasing the risk of a rear-end or multi-vehicle collision. This condition occurred immediately following the engine failure and was not accompanied by any prior warning or instructions to allow safe vehicle repositioning. I am unaware of any manual or mechanical override that would allow the vehicle to be shifted into neutral under these conditions. This design behavior represents a safety defect because it compounds the danger of a propulsion loss by preventing drivers from removing the vehicle from harm’s way.

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
I am reporting a catastrophic engine failure involving my 2023 GMC Yukon XL Denali, which was subject to a GM-issued recall related to engine failure. On January 10, 2026, at approximately 1:00 a.m., while traveling at highway speed (approximately 65+ mph) on a multi-lane highway, the engine suddenly failed without warning, resulting in a complete loss of power. I was forced to make immediate evasive maneuvers to reach the shoulder while avoiding semi-trucks and other vehicles. The sudden loss of power created an extremely dangerous situation for myself, my passengers, and surrounding traffic. After the engine failure, the vehicle could not be placed into neutral, preventing it from being moved out of traffic if it had stopped in an active lane. This design issue significantly increased the risk of a collision. I was stranded on the roadside for several hours in cold conditions awaiting a tow. The failure was later confirmed by an authorized GMC dealer, who diagnosed the engine as failed and replaced the entire engine assembly. The vehicle and replaced components should be available for inspection through the dealership. The manufacturer had previously issued a recall for this vehicle related to engine failure, and I had requested a buyback prior to this incident due to safety concerns. That request was denied unless the vehicle experienced a failure. There were no warning lamps, messages, or symptoms prior to the failure. The only warning message appeared after the engine failed, indicating an engine overheating or “engine hot” condition, which occurred after power was already lost. This incident represents a serious safety defect that resulted in loss of propulsion at highway speed with no advance warning.

Vehicle was taken to dealership and test was run. Service manager notified me it passed and told us about change of oil. Then recently engine stopped on us twice on the interstate with no power. We finally got it to the dealer and while they were test driving it lost power and they had to have it towed. Now we have been told we are needing a new engine and have not been given any time line. We have also read that many time the solution even on the new engine is not fixing all issues. We just want a safe vehicle returned to us.
