I have replaced the battery and alternator. My door locks keep locking and unlocking on the own while driving, all my electrical in my car dim and keep resetting, my gauges are going all over the place. My car will turn itself off. While stopped at a red light, it seems to want to go on its own. While not running, I get in to leave, and my key at times don-€™t want to turn over. Then at times I try to start it and it will tell me theft control and won-€™t crank. When I-€™m out of my vehicle at home, my car will lock itself when the setting is turned off. The problem has been going on for a year but only getting worse now.

My 5th cylinder exploded. I had a P0305 code for 5th cylinder misfire, took into the dealership and they replaced the coil pack on that cylinder on 10/20/2020 and 01/17/2021 the 5th cylinder exploded cause chunks of metal to be thrown through the side and cause a catastrophic engine failure. It was stationary in a parking lot but I was just about to put the car in reverse to drive when I hear a noise and shut the car off. Upon further research there is currently a class action lawsuit against the GM for the high failure rate of 2010-2014 years for vehicles that used the 5.3liter engines; the 6.2 liter engine, the one in my vehicle, was manufactured in the same plant as the 5.3 liter. GM failed to disclose to the public of the known defect to the engines.

Travelling at speed on the highway (60 mph), the engine light comes on and a stabilitrak message is shown. Power to the engine is dramatically reduced. Car shakes violently and it is difficult to get off the highway. A seconday message appears to check throttle body assembly. Very close to getting rear ended. This is a major defect that has to be addressed. It has also occurred on a 2014 GMC Yukon XL that we own.

The vehicle suddenly lost power and the stabili-trac system warning appeared in the dic, then the traction control system warning appeared in the dic, then engine power reduced by 16% in the dic. Drove vehicle to exit ramp and turned engine off. Vehicle restarted with only the check engine light on and no warnings in the dic. The engine did not however run smoothly. I took it to a dealer who clear some codes and replaced the tps. Checked all fuses. No further problem. However a friend has the same vehicle in a 2010 model. Same problem dealer replaced a throttle body. Check out the GM forum at [xxx] this forum shows literally hundreds of complaints about the same problem and in some cases causing accidents. My vehicle was repaired on 1-24-2013, and so far it appears that my problem has been resolved, however it appears GM is not really fixing the problem. I am concerned about this for the next out of town trip I take.
