Engine failure at 38k miles No service lights on dash. GM says 4 months to get replacement motor with very little help on getting rental car

While traveling on the interstate my vehicle shuttered and lost power we went to a friend’s neighborhood and the vehicle stalled when we pulled in no lights had come on until then and a knock had started. With no where to pull over I finally got the vehicle started and drove it straight to our friends house and left in on the side of the street. I had to take there vehicle home and called ONSTAR to tow it to the dealership. I have to pay for the over mileage because I was out of town when it happened.

The vehicle has experienced numerous losses of power, it has nearly stalled during normal operation, there is a horrible knocking noise coming from the engine. I have had the vehicle into the dealership who state they are unable to recreate the issue, and since the vehicle has been turned off the recorder shows noting either. They have performed an inspection and changed the oil, but the vehicle still has the issue. It knocks and shudders like it's cold, it comes very close to stalling and then seems to recover, this has happend twice while making left hand turns, it has completly lost power even while depressing the gas, but again they indicate they can't recreate it, so there is nothing they can do. I am scared for my safety, and that of the child I drive daily. There have been several i

The vehicle underwent a recall inspection on September 8, but on October 2, the vehicle still experienced a serious engine failure. The vehicle was undrivable, and the dealer inspected it and opened a TCA case. However, General Motors stated that it had passed the recall test and was not covered under special warranty, and asked me to pay $5,000 for vehicle repairs. I believe this is an engine malfunction related to the recall, and the manufacturer should replace the engine for me free of charge and refund my 5,000 .

vehicle keeps stall and loose power , I've been to the dealer many times and they replaced many parts (paid out of pocket)and the problem still , so after all of that and the struggle for months that i need to replace the engine . so i did replace the engine that cost me over 6k (out of pocket) and the problem is still , i went back and forth to the dealership and couldn't figure it out or reimburse me for anything.

The same motor in this truck is part of one of the biggest national recalls in GM history. With that said my truck experienced the exact same issue where the engine rods warp or bend when they heat up causing to damage the crank shaft and the motor to seize. This is exactly what happen to my truck, but yet my trucks vin number is not part of the national recall? I was also told that I would receive assistance for the repair and a rental reimbursement and I am yet to receive neither. Something doesn't seem right and it needs to be investigated further. On top of all that, this has been ongoing since March of 2026. The truck was bought at West Palm Beach Cadillac and is currently still at the service center at Island GMC in Staten Island NY.

The engine of this car failed at high speeds on [XXX], in [XXX], at 40,000 miles. GMC claimed the lifters in the 3rd cylinder failed and they were replaced under warranty. The lifters in the 3rd cylinder failed again, at high speeds on [XXX], at 77,000 miles. GMC claimed the lifters and crank shaft needed to be replaced. After paying for the repair and getting the car back, the engine locked up and failed within 30 miles of being fixed at 77,000 miles. Prior to these issues, there were no warnings and no symptoms. The car supposedly was not included in the engine recall by GMC. Two of the three incidents happened at speeds of 75 mph, the third occurred on a highway and speed of 55 mph.

I am writing to formally file a complaint regarding a serious and ongoing issue with my vehicle that has placed my safety at risk and resulted in significant inconvenience and financial burden due to General Motors’ failure to honor my warranty in a timely manner. While driving on the highway, my vehicle suddenly began losing power and displayed flashing warning messages indicating that it would not shift into gear or out of gear and that power could be lost. This created an extremely dangerous driving situation and posed a serious safety risk to me and other motorists. I brought the vehicle in for warranty service, but General Motors was unable to honor the warranty repair in a timely manner. As a result, I was without my vehicle for several months while it sat undrivable on the dealers

Engine oil level drops significantly well before the oil change interval. Vehicle consumes excessive oil without warning lights or leaks. Risk of engine damage or failure if oil level is not closely monitored. Condition discovered during normal use.

Vehicle has 56000 miles currently and at 47000 transmission had to be replaced due to defective valve body. At 56000 miles, motor was replaced due to broken lifter. The vehicle currently will not start.

While driving the vehicles went into limp mode with a transmission issue. Vehicle was towed to the dealership where I was informed the transmission body valve has failed. Vehicle has been out of service for 3 week so far, still not fixed.

On May 23, 2025, I purchased a 2023 GMC Yukon XL VIN: [XXX] from the GMC dealership.
 At the time of sale, I specifically asked about the active GM engine recall. They assured me the vehicle had been inspected and was unaffected. On October 30, 2025, the engine catastrophically failed on a highway while my family — including my two small children — were in the vehicle. This created a dangerous emergency situation as I had to avoid high-speed traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At around 7pm on Sunday October 18th I was driving on an interstate at about 80mph in the far left lane (of 3 Lanes) when, without any warning whatsoever, the engine power completely shutoff and the car went into neutral. The dash screen said to start the engine due to no power or low battery. I hit the start button and all the lights including all controls, blinkers, dash lights shut off. So with no blinkers, no lights, no power brakes, no power steering we were coasting in the fast lane of a usually unsafe stretch of an interstate at night. Luckily, I was able to navigate without any power to the right shoulder (lucky this was a stretch that had a shoulder) and coast to a stop. I had my wife and 4 kids in the car with me. The car was dead and said the engine battery was low. When the en

The contact owns a 2023 GMC Yukon XL. The contact stated that while driving 75 MPH coming to an intersection and attempting to apply the brakes, the vehicle failed to stop as needed. The message brake system failure and speed limited to 62 MPH were displayed on the instrument panel. The vehicle continued and drove through the intersection. The parking brake failed to stop the vehicle. The vehicle ended up stopping in a ditch and was towed to the dealer to be diagnosed. The contact was informed that the battery terminal had detached, causing 20 different modules to fail. The battery cable was tightened. The manufacturer was made aware of the failure and opened a case for a possible buyback. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage

The contact owns a 2023 GMC Yukon XL. The contact stated that while driving approximately 25 MPH and depressing the brake pedal, the vehicle failed to respond. Several unknown warning lights were illuminated, and the message "You Have no Brakes - Do Not Drive Over 40 MPH" was displayed. The contact allowed the vehicle to roll to a stop. The contact turned off and restarted the vehicle, but the failure persisted. The contact parked the vehicle. The contact stated that the failure had not caused an accident because the contact was driving early in the morning and there was less traffic on the road. The contact stated that her husband started the vehicle later in the day, and the warning lights were off. The vehicle was driven to the dealer to be diagnosed. The dealer diagnosed the vehicle an

While driving through rain on a long car trip, the wipers suddenly became completely inoperable. We could not see and were on a highway causing a serious safety issue. We had to drive very carefully off the next exit ramp. Tried turning on and off the car, no luck. Tried toggling the rain sense on the display and finally wipers came back on. About 20 miles down the road the same thing happened. Wipers became inoperable. We had to exit highway 4 times to try to wait and toggle for wipers to come back on. Immediately had it checked my a mechanic at our destination and he could find no cause for the incident. Our best guess is there is some computer glitch that needs to be fixed and I predict there will be a recall. Hopefully not before a disaster.
