2024 GMC YUKON Complaints

Vehicle started making a knocking noise. Made a service appointment. While on the highway, engine suddenly died causing the vehicle to shift into neutral. After stopping on the shoulder, vehicle locked into Park and would not shift back into neutral or start again for tow truck driver. Towed to nearby dealer who said the engine is beyond repair and has to be replaced. Estimated time to get engine and replace is 4 to 6 weeks.

2024 Engine failed while moving at 70mph out of state. De-accelerated rapid as I was changing lanes and was almost hit by two vehicles. Once of the interstate, I made it to the shoulder of an exit ramp that was a blind spot. Cars exiting to this ramp almost always had to veer to keep from hitting me. I purchased this vehicle in October 2024, never knew anything about a recall, was never disclosed to me about recalls. To this day, if I enter my VIN, there is no recall and I have never received any communication stating this vehicle was on recall. I complained to the dealer twice about unusual noise from vehicle, which they dismissed. I took it back to the dealer because my oil light indicated I was "low", this oil is too low, my concern was a leak. Took into GMC dealer, they stated we did not see any leak. Now this. Problem, GA law states in order to qualify for buyback, 24,000 miles or under 2 years. Well, I have 24,986...this automatically disqualifies me. SMH The options I was given are all a NO WIN for me! I was almost killed on the interstate, not to mention the level of stress and issues this car nightmare has caused me. $100k vehicle and I still owe 87K

1.XXX XX— GM Recall Notification (Recall No. N252494000) I received official notification from General Motors of Recall N252494000 affecting my vehicle. I brought the vehicle to [XXX] as directed to have the recall remedy performed. 2. XXX — First Report of Engine Propulsion Issues I reported engine propulsion concerns to Jim Ellis. This was my first formal complaint regarding the performance of the vehicle following the recall remedy. 3. XXX — Oil Type Change Performed by Jim Ellis Jim Ellis performed an engine oil type change, switching to 0W-40 oil, and advised me that this change would serve as the fix for Recall N252494000. I accepted this remedy in good faith. 4. XXX — Low Oil Warning Light Activated Approximately nine months after the recall remedy, and well before the end of the recommended oil life cycle, the low oil warning light activated on my dashboard. This is abnormal and indicative of excessive oil consumption. I returned to Jim Ellis, who performed a fresh oil change and placed my vehicle on a 6,000-mile oil consumption test — an acknowledgment that an oil consumption problem exists. 5. XXX — Active Engine Misfires, Jerking, and Flashing Check Engine Light While operating my vehicle on Sunday, May 31, 2026, I experienced severe engine jerking and misfires. The check engine light began flashing — not steady — which I understand to indicate an active and serious engine misfire event. I was genuinely concerned for my personal safety and immediately parked the vehicle. It has not been driven since. 6. XXX — GM Corporate Case Opened I contacted GM Customer Care and was assigned Corporate Case Number INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On our way home from vacation our engine failed and stranded us. This is the second engine that has failed and the vehicle only has 30220

I would like to document it took 7 trips to set the monitors after a failed smog check. That is 21 time going from 55 miles a hour to coasting to 20 miles a hour. on a freeway. Three times per trip at 2:00 - 3:00 in the morning. Also my Catalytic Converter went out at 26,000 miles. It should last 70,000 - 100,000 miles or 10 years. Catalytic Convertor was replaced by dealer. Will i have to replace it every 26,000 miles?

Engine failed- threw a rod Available for inspection Engine failed in the middle of a 6 lane interstate with 70mph speed limit. Locked up. Loss of power. No warning. Engine replacement needed- confirmed by dealer. This is the second engine replacement in less than 2 years Vehicle purchased in June 2024 Engine replaced June 2025 Vehicle taken to Glockner of Ironton Ohio in Aug 2025, Jan 2026, Feb 2026 and March of 2026 due to a knocking and ticking noise in motor. I was consistently reassured it was a normal sound per GMC. Engine locked up in the middle of the interstate may 15, 2026

My engine ticks, and during the winter, I noticed white smoke coming from exhaust pipes in cold and warm weather. I believe there may be an issue with my engine. My vehicle is not on the list provided, and I’m concerned that the dealership responsible for my oil change package will not identify the problem, possibly because newly hired mechanics may lack the experience to make an accurate diagnosis. I’m afraid my vehicle will be overlooked intentionally.

For the third time, my vehicle died on me while I was driving; 2 of those times were on the highway going highway speeds. The last (3rd) time, I was towing my travel trailer/RV on the highway. In all incidents, the engine stopped propelling the vehicle. I could see and hear the engine revving but I failed to accelerate. After various warnings on the dash, I was able to pull safely off the road and then the engine just stopped, and nothing else worked. It failed to restart. This could have been a potentially dangerous situation because had I not been able to safely pull over, I would have been rear-ended. My vehicle was not part of the L87 recall for the 6.2L GM engines but the symptoms sound the same as those that were. The recall probably should have been expanded beyond the dates that GM originally included.

Had my oil changed Wednesday and noticed a new noise. Brought to dealership, this particular year is known for 6.2 L engine failure but was told mine wasn’t in the recall. Well I was told today I have engine issues and they are replacing

First incident April 9 2024 not even a month after purchased. Vehicle dashboard lit up light a Christmas tree all warning lights while driving on highway. Vehicle shook and sputtered and turned off. The vehicle was serviced explanation given was loose spark plugs on a new vehicle. 2nd incident roughly month after recall repair for engine propulsion campaign. February 26 and 27 2026 . While driving the following lights came on Engine failure ,Brake failure , Service Transmission now unable to shift soon. I was terrified because I could not control the vehicle. I had the vehicle towed to the dealership. The answer to the issues was Battery failure. Third incident April 17th 2026 I driving on highway 70 miles check engine light comes on flashes dashboard goes dark. Vechicle sputters and shut down. I restarted the vehicle the warning on the display disappeared and the vehicle restarted. I reached returned the vehicle again to the dealership because the problem resumed slowing down even though I’m depressing the gas. Vehicle is shifting and dragging. Resulting unexpected lurching. My vehicle has been at the dealership since end of April 2026 it remains there currently. My representative stated a code indicating misfiring has appeared 18 times. Also everyday my vehicle keeps saying software update even I installed the update and it says complete. I know GM is not updating my vehicle software everyday. That indicates there is a computer issue as well. My anxiety level is through the roof at this point. I complained before about this same failures in a Cadillac Escalade prior to it lurching forward and crashing. I filed a complaint before February 2024 . There is something really wrong with GM engines and software. I know I’m not the only one experiencing these problems
