Apr 08, 2025

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

-Automatic transmission failed. Slipped, skipped, and bucked while driving. -Taking a left turn into traffic transmission hesitated and just started slipping almost causing an accident. -Dealer confirmed torque converter failed and transmission needed replacement. -No warnings. No towing. Just 89,000 highway miles commuting to work. No heavy loads or abuse. -Had to replace the transmission, not covered under warranty due to mileage. Not available for inspection.

Transmission failed while driving down the road. Trasmission reved up while driving and would not go faster then the car started slowing down. Thank goodness this was not on an interstate or it could have caused an accident. Check engine light came on as I was getting to the shoulder of the road.

2019 GMC Youkon with 94,659 miles. I am the second owner of this vehicle. I purchased it used in February 2025. Check engine light came on in route to work on March 5, 2026. Immediately took vehicle to Auto Zone to scan for codes. Multiple codes were returned. I drove it directly to a repair shop for further diagnostics. Return Results were massive lifter failure and cam shaft damage. Why would the check engine light not come on sooner to prevent TOTAL FAILURE. Vehicle was towed to a GMC certified mechanic where it was confirmed that all Lifters and cam shaft were damaged beyond repair and must all be replaced.

Driving out a town 400 miles away, with a young passenger in my car on [XXX] in rush hour traffic, i started hearing a slight ticking sound then moved into a full blown knock on my drivers side ( I recorded it). within minutes, my oil light came on and my dash notification reading "engine overheating idle" with the knocking really load. I had to cross 3 lanes to traffic quickly to get to the shoulder of the road, which was NOT a safe place. I smelled smoke and cut the the engine off. I popped the hood to see that there was now no coolant (that is all I knew to look for). I immediately called OnStar Roadside assistance. 2 hours later, I was towed to a local hotel room. Car completely dead. not lights, couldn't lock it, nothing. I had to pay a large fee (almost $2k) to have my car towed back to NC from AL not to mention having rent a rental car to get us home. the car is now at a GMC dealership in Monroe NC. of course the Powertrain extended warranty doesn't cover the Battery replacement, belt replacement and water pump replacement so now I'm out of pocket $1300 just to get those install to be able to try and start the engine to further diagnose if my I have complete engine failure AND without transportation.

SEAT BELTS

1 complaint

The seatbelt on the second row driver side captain chair no longer works. It started not retracting about a year ago and now it won’t retract or pull out so it is stuck and cannot be used. The $85k Yukon is only five years old, seat belts should last longer than that. GMC wants us to pay $500 to fix a safety concern seat belt. I would understand if the vehicle was 10+ years old but we are still less than 100k miles and we just hit 5 years.

ELECTRICAL SYSTEM,SERVICE BRAKES

1 complaint

Received a message on driver information system that states service trailer brake system. When towing a trailer, the trailer brakes are inoperable and pose a safety risk in the event of a sudden brake event. GM apparently has a service bulletin published for this message which indicated a replacement of the connector in the wire harness should be performed. Although I don't tow trailers often, I should be able to rely on this feature in my vehicle. My vehicle only has 70,000 miles and this is too soon for such a part to become faulty.

THE VEHICLE WAS TOWED IN TO THE DEALER ON 01/13/2020 AND WAS ALSO TRANSPORTED TO THE SAME DEALERSHIP AGAIN ON 02/20/2020. A TSB WAS PERFORMED BY THE DEALERSHIP WHEN IT WAS TOWED IN THE FIRST TIME THAT OBVIOUSLY DID NOT FIX THE ROOT CAUSE OF THIS PROBLEM. NORMALLY THE PROBLEM WILL GO AWAY AFTER A PERIOD OF TIME AND THEN THE DEALERSHIP CLAIMS THAT THEY WERE NOT ABLE TO REPRODUCE THE CUSTOMER'S COMPLAINT. I DO HAVE VIDEO FOOTAGE OF THE ISSUES I EXPERIENCED ON TWO OCCASION AS PROOF.
