2022 GMC Yukon engine problems

“Vehicle: 2022 GMC Yukon AT4, 6.2L V8 (L87) Mileage at Failure: 159,605 My 2022 GMC Yukon AT4 experienced a complete engine failure at approximately 159,605 miles. The engine seized and could not be manually rotated. The vehicle was inspected by Wallick's Auto Service, which confirmed that the engine was locked up and the oil level was only approximately half a quart low. In July 2025, Green GMC performed the GM recall remedy related to potential engine failure on the 6.2L L87 engine. Rather than replacing the engine, GM's approved remedy consisted of changing the engine oil, oil filter, and oil fill cap. Despite having the recall performed and continuing regular oil changes, the engine failed approximately 15 months later. The most recent oil change was approximately 4,100 miles before the failure. The vehicle was subsequently towed to Green GMC for evaluation. GM declined financial assistance toward the approximately $16,856 engine replacement I am concerned that the recall remedy did not adequately address the underlying engine defect and that my vehicle experienced the same type of catastrophic engine failure the recall was intended to prevent. I am…”

“The engine completely quit while driving on the freeway going 65-70 mph in the number 1 lane. Tried getting the vehicle to restart and nothing happened. Took vehicle back to dealership and they stated the vehicle needed a completely new motor. The same incident just recently happened after they replaced the whole engine, and they are indicating it is the same issue, and claiming will need a new engine.”

“I am filing a complaint about a serious safety issue with my vehicle. While I was driving on a highway with my spouse and children in the vehicle, the engine began downshifting, the check engine light came on, and an “engine oil hot” warning appeared. The engine then suddenly shut down. With traffic behind us, I had to pull off onto a dirt road in a rural, secluded area. This put my family in a frightening and dangerous situation. The vehicle had to be towed to a dealership. After inspecting it, the dealer told me it needs an engine replacement. This would be the second engine replacement for a vehicle that is less than four years old. I have owned this vehicle for only two and a half weeks and have already had to take it to the dealership twice for major repairs. It is unacceptable to make payments on a vehicle this new that has proven so unreliable, especially when it can shut down without warning while my family is traveling. I am requesting a prompt resolution to both the safety issue and the repeated engine failure.”

“April 2026-Yukon shut down on highway (needed apparent fuse replaced) May 2026- Yukon went in for new engine *was in for 68+. Between the two stays. July 2026- (7/7)- got vehicle back, had two dents on the front and a. back dented fender. Towing was hired by GM, not us. -July (7/22) -vehicle shut down on me at a stop sign in an intersection. Was brought in and fixed a voltage sensor (220.00+). Also discovered a blinker issue (per the dealership the LEDs are shorted, etc. quotes 900.00+ for the whole unit).”

“Persistent lifter/valvetrain tapping noise, particularly around 1,500 RPM. 2022 Yukon 88,000 miles. Engine consumes more than 2 quarts of oil in between oil changes. Was told by dealer in the past that this was in normal range.”

“My engine has failed twice. I am now on my third engine. The vehicle stalled while driving on a highway, was in the shop for nearly 3 months and was "fixed" with same 6.2 engine. Eight months later it stalled again was in the shop for 2 months with a new engine. I was informed that they still don't know the issue and they just put the same type of engine. A bandaid was placed in my vehicle and I'm suppose to feel safe in it.”
