2019 GMC Yukon Electrical System Problems

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failure at 114k miles required replacement.

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.

The contact owns a 2019 GMC Yukon. The contact stated that while driving at an undisclosed speed, the service trailer brake system warning light illuminated and alerted the contact. The contact stated that there was no trailer brake. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and the contact was advised to take the vehicle to the dealer. The failure mileage was approximately 13,000. The VIN was unavailable.

Tailights are not working as per the dealer (Thompsons GMC of Placerville, CA). Unable to drive the car at night or near sunset.

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 contact owns a 2019 GMC Yukon. The contact stated that the third-row seats electrically controlled failed to function as needed. The contact stated that that the seats failed to move forward or backwards. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the third-row seat unit needed to be replaced. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The contact researched online and related the failure TSB: PIT5550C (Left Side Third Row Seat will not Power Fold/Unfold Seats, Electrical System). The failure mileage was approximately 34,000.
