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.

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.

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.

LOSS OF POWER STEERING, LOSS OF ELECTRONIC STABILITY CONTROL, LOSS OF ALL TRANSMISSION GEARS FORWARD AND REVERSE, LOSS OF AUTOMATIC HEADLIGHT CONTROL, LOSS OF INSTRUMENT CLUSTER GAUGES INCLUDING TACHOMETER, ENGINE OIL PRESSURE, AND ENGINE COOLANT TEMPERATURE, LOSS OF HEATED SEAT FUNCTIONALITY, LOSS OF HEATING, VENTILATION, AIR CONDITIONING, AND LOSS OF INFOTAINMENT/STEREO SYSTEM. THIS PROBLEM HAS OCCURRED ON TWO OCCASIONS NOW, THE FIRST ON 01/13/2020 AND THEN AGAIN ON 02/20/2020. 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.
