2022 GMC Yukon: check engine light

Filed Sep 29, 2026 · Engine, Fuel system · AL

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.

Sunday XXX, we were riding in our 2022 Yukon Denali with my wife driving on [XXX] at the speed limit of 75 mph when the vehicle stumbled for a moment then returned to normal operation... a few seconds later the engine just died. No drive information center warning or check engine light, no funny noises or catastrophic banging. It just quit running. There was traffic on the highway but with my wife's quick reaction we were able to get off the highway to the breakdown apron without crashing. We called AAA and had the vehicle towed to the GMC dealer (Oxendale GMC) in Flagstaff. We were at this point about 200 miles from home in [XXX] City. On Wednesday, XXX, the service writer called us and informed us the engine was seized and would have to be replaced. We were aware of the NTHSA recall and had taken our vehicle in on XXX to have the recall (N252494000) and at that time we passed the pico test and the oil was upgraded to the higher viscosity and oil fill cap changed. We were sent on our way with no advisory the recall may not have fixed the underlying problem. GM has agreed to replace the engine. We filed a complaint with GM (GM case #XXX) Since this happened, we have been looking into this situation and discovered ours is not an isolated case. A lawyer told us that here have been more than half a million vehicles recalled and an unknown number of catastrophic engine failures just like our, but NTHSA has received less than 1000 complaints. I wanted to make sure that my experience was conveyed to you. An additional note - we special ordered this vehicle new and began to have recurring electrical problems with it shortly after we took delivery. GM offered us a buy-back or a 100,000-mile warranty to keep the vehicle. Since then have had the vehicle serviced at regular recommended intervals by Brdley Chevrolet in [XXX]. We have repair invoices for every service and Recall repair done. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Had a check engine light come on a couple months ago and vehicle went into Reduced Accelaration safety mode. Come to find out, it was a faulty Valve Body. I came out of pocket for $2,800 to get it replaced because GMC said the Valve Body/Special Coverage was not assigned to this VIN. Even though it was a 2022 with 60,000 miles on it fitting every criteria of the exact recall (mind-blowing). Now fast forward to now, the same check engine light and reduced acceleration fault is active associated with a Transmission Control Module Fault. This truck is entirely too new and taken care of to be dealing with these types of major issues. It’s been a severe inconvenience for my wife as it’s her daily driver. To make matters worse, the lack of support and assistance from GMC has made us go from very loyal customers and supporters, to now seeing how quickly we can get away from this disaster of a vehicle and Customer Service.

I was driving on the Northeast extension at roughly 70 mph in the passing lane and my car lost forward power and went into reduced acceleration mode. The check engine light is on, violently shakes when parked, with additional dashboard notifications saying Service ESC, service traction control, and forward collision system unavailable. I had my engine replaced in September due to the recall.

Gateway system module failed during the L87 recall service.The major L87 recall (ECM update) is a major, high-load software update that frequently causes the Gateway Module to "brick" or stop communicating during the update process resulting in failed module immediately following the service. (TSB) speak to this, The L87 recall is a safety-critical repair, a failure of a module directly caused by this repair should be covered under a recall warranty or GM warranty. Safety can be affected as warning lights will not work due to this failure. Timeline of events. As soon as warranty service was completed before leaving bay lights were not working like Onstar etc, app wouldnt connect to car, 1-2 hours after leaving service engine light came on in car. Never had an engine light on before. Took back to dealer who said it was a computer issue they corrected it. 2 hours later engine light was back on. My car has been at the dealer since Monday when they called to say the GSM had internal failure and wanted to charge me to replace it despite this internal failure being in response to the warranty service that was provided, There are Technical service bulletins about this issue, this has been a known issue with GM vehicles, My timeline shows strong evidence that the failure is a direct result of the recall repair.

GM needs to extend the GSM repair/recall or extend coverage for this repair when this happens. This is just another thing GM is not taking responsibility for.

My 2022 GMC Yukon with the 6.2L V8 engine is covered under recall 25V274000 for connecting rod and crankshaft defects that can cause engine failure. Approximately three months ago, Wiesner GMC dealership performed the recall inspection and stated the vehicle passed. Recently, the engine suddenly began misfiring on cylinder 6. The failure was sudden and severe—the vehicle started shaking significantly, the check engine light illuminated, and multiple safety sensors began deactivating. The vehicle was clearly unsafe to drive. An independent repair shop diagnosed oil leaking into the cylinder and stated the condition is consistent with internal engine component failure—the same type of defect the recall is meant to address. When I contacted the dealership to have it re-evaluated, they stated my vehicle is no longer under standard warranty and I would be responsible for repairs. After escalating to GM customer service, they confirmed extended coverage exists under Special Coverage N252494003 (10 years/150,000 miles) if the diagnostic confirms the issue is related to the recall defect. The fact that my vehicle passed the recall inspection three months ago and is now exhibiting the exact failure symptoms the recall was designed to prevent raises concerns that the inspection procedure may not be detecting all affected engines. The component (engine) is available for inspection. This defect poses a serious safety risk as the sudden loss of power and deactivation of safety systems could cause a crash.

After only 47,000 the Yukon started with hard starts and triggering a check engine light. Owner suggested fuel issues, the dealership suggested a bad wire. They adjust the "bare wire", and mentioned that the fuel pumps on these vehicles have issues and they would order one- but give them a holler when we have additional problems. The Yukon continued to hard start, evolving into stalling when started. The dealership was alerted but due to lack of engine codes being stored the dealership couldn't help us. Eventually when driving 57mph, the Yukon cut engine on a busy route, driver was able to get the Yukon to the shoulder and attempted restart- the Yukon was dead. AAA attempted to battery jump the Yukon without success. We were without our Yukon for 8 weeks, being placed in random trucks that couldn't support our family size. Upstate Chevy of Attica was not help in the process. We did contact GM directly and received a case number 9-14907008493. The engine was replaced. The Yukon still doesn't seem to be 100%, with some slow to starts. We are asking for compensation toward another GM full size SUV. We are GM friends and family and have purchased several vehicles over the years. We'd like to trade our suv now for a new 2025 without engine issues- but since our Yukon was gutted, that is now noted on a carfax which devalues our trade.
