general problems of the 2019 GMC Yukon

Driving out a town 400 miles away, with a young passenger in my car on hwy 459 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.

The air conditioning system in my vehicle failed in April 2025. My dealership service department diagnosed the problem as a refrigerant leak requiring the compressor to be replaced. I had the $2400 repair made replacing both the compressor, condenser and the a/c system was charged. 2 months later, I am having the same issue again - failure of the a/c system due to a refrigerant leak requiring the condenser to be replaced. A quick google search identifies a recall on the 2019 Yukon xl noting a "refrigerant leak due to thermal cycling". Though this is the precise year, make, model and distinct problem that I am experiencing, my specific VIN has not been included on the recall. We are in the height of summer, currently experiencing temperature that feel like 104-107 degrees in east tennessee thus is has become a safety issue for myself, 4 children and husband to travel in our primary/only family vehicle. I find it unbelievable that a vehicle of this caliber has a basic (air conditioning) system failure after 6 years; however, it is incomprehensible to spend $2400, have it repaired, know there is a recall for the precise vehicle and concern, have it fail again and be expected to spend another $2400 because my specific VIN is not included. It is simply preposterous. I am requesting that my specific VIN be included on this recall, please.

The engine continues to slip and slows down when driving. The following codes are returned back from the onstar diagnostics, transmission control module requested malfunction indicator lamp illumination. The dtc is an informational dtc. The dtc indicates an emission related dtc set in the transmission control module. The vehicle has only 132,000 miles, and I have maitain the vehicle in excellent shape. With maitainance, the transmission should last at least 300,000 miles. The engine and transmission system is not performing as expected. An issue has been detected in the transmission system that transfers power from the engine to the drive wheels.

Service trailer brake system keeps coming on while driving. Dealership says nothing wrong although they replaced fuse. Still happening. Only thing that seems to work is pulling off road and restarting vehicle. That is only a,temporary "fix". Comes back a few days later. This is a safety issue as 1) distracts me while driving 2) I pull an 8,000lb travel trailer with the vehicle.

Vehicle caught fire in my driveway and burned to the ground. My wife and I drove to dinner and came home around 830pm on Friday night (03/26/2021). The next morning (Saturday, 03/27/2021), I was walking past the front door around 8am and noticed flames coming out of the grille (under the hood) when I looked outside. Told my wife to call 911 and I ran outside and tried to put it out with the fire house, but it was too late and the fire took over. The fire marshall stated it was an electrical system failure that caused the fire.
