2019 GMC YUKON Complaints

Was driving home at highway speeds and my 2019 yukon denalis engine just shut off in traffic and had to come to a stop in the middle of traffic and it wouldn't restart, had to have it towed to dealer and they told me the engine was siezed.

Catastrophic engine failure to the GM 6.2L engine. Mechanical issue - cam or crankshaft came apart. Safety to myself and/or others as I was driving on the road in traffic when the issue occurred and had complete loss of power. I was able to avoid traffic and get the SUV to the shoulder of the road. The issue was confirmed by my auto service provider. No warning lamps or messages prior to failure. Once failure occurred, the check engine light started to blink.

There was a problem with the catalytic converter that I was not aware of when I purchased the vehicle. There were no issues with performance for a few days until the engine began misfiring on the interstate and it forced me to pull over during heavy traffic. This was all in a week and the dealer has refused to take any responsibility despite being a Chevy Certified Dealer. I am now getting the vehicle repaired by my local mechanic due to the need for this vehicle. I have made General Motors aware of the situation.

Transmission failed at 90,100 miles. Left me stranded in middle of a busy intersection as I was making a left turn, it was like it was in neutral no matter how much I tried to accelerate. Very dangerous situation, scary and helpless feeling as cars approaching and I could not get out of their way. Near miss accident. This should not be happening at this low mileage

Total engine failure with no warning. Vehicle has approximately 106,000 miles. While driving on Monday [XXX], the car began shaking violently and the engine light began flashing. Fortunately I was only about a mile from a GMC dealership, so I pulled into Rice GMC Buick in Knoxville, TN. They informed me that there was a catastrophic engine failure and that a complete replacement would be necessary at a cost of $15,000 dollars. I live 100 miles away in Chattanooga, TN. I understand that cars experience some level of wear and tear, but a total engine failure at just over 100,000 miles when the car has been serviced at all regular intervals is very unusual. I recommend my case be referred to active investigation #PE25001. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car was clicking when it was first started up, a short time later it started to shake terribly which forced my [XXX] son who was driving the vehicle at the time to pull over, on a major toll-way in heavy traffic. Engine light started to blink and traction control light came on. I immediately took the car into the dealer and was told I need new lifters ($3800 + Tax) and most likely a new engine (they quoted me $15,865). From what I am reading this issue is common place with the 6.2L engine...frightening and very lucky my son was not injured. I have filed a case with GMC - Case #[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The message "Battery System failure" was displayed on the instrument panel. The contact stated that the GMC App diagnosed the vehicle with Stabili-trak Stability Control System Failure. The vehicle was towed to a local dealer where it was diagnosed with metal shaving in the engine which caused the noise. The contact was informed that the engine needed to be replaced. The vehicle was not repaired due to the cost and remained at the local dealer. Upon further investigation, the contact related the failure to an undisclosed NHTSA Investigation. The manufacturer was made aware of the failure. The failure mileage was approximately 115,000.

GMC engines are faulty and puts people at risk when they malfunction. The first time the vehicle lost power, It was spitting and sputtering as i was driving with my family in the car. The vehicle Left us sit along side the road of a major highway in freezing temps. The lifters malfunctioned costing 5000 dollars in repairs. Once again started having loss of power and the vehicle shut completely down while driving down the road with my family in it. So no engine means no power steering an etc . Again left us sit along side the road. The main bearing has went in the motor. Now costing us 16,000 in repairs For new engine. Now we are at the cost of 21,000 in repairs. This is a known issue with the v8 engines a yet GM has done nothing to fix or compensate people for their loses. I’m stuck with this vehicle now cause I’m so upside down at this point it’s disgusting. Also sad an auto manufacturer doesn’t NOT stand behind their product as it puts people and their family’s at risk. They NEED TO BE held accountable for this issue as thousands of people have had this issue. I don’t have the other repair bill on me at this time do to the car is in the body shop from a deer accident. But I do have one an can provide it at a later date if needed. Thanks

We received an alert/warning that is nearly constantly beeping and servicing the trailer brake system. We have never used the wiring or towed anything, and the trailer brake system is unused. The beeping is near constant, even after we “dismiss” the alert and is very distracting when driving.
