| Electrical System problems |
On 3/14/26, on I-75 in troy, michigan at 70mph the vehicle, with 4000k miles on the odometer completely shut off. I pushed to restart the engine and it would not restart. My whole family was in the car and we were on a curve. I was able to coast to a flat shoulder. The vehicle would not restart or shift out of park. Onstar took seven hours to tow the vehicle. The dealer is installing a new l87 6. 2l engine. I do not have the vehicle back yet. I received an economy car as a loaner. The dealer says gm will not extend the factory warranty despite the engine replacement. My family could have been easily killed.
The infotainment screen which controls the a/c, heating, defrost, cameras and all other info for the vehicle does not come on in th vehicle. This began happening after owning the vehicle for 3 days. After taking to the dealer, delray GMC, we were informed by the service personnel on our second trip in for the recurring problem that general motors knows this is a problem and are selling the vehicles with this factory engineering design defect and currently there is no repair. Living in florida this is a problem in the extreme heat with no a/c, being from illinois, when we return this will be a serious problem, not knowing if we will or will not have access to heat, cannot control the temperature or the defrost on the vehicle and having a infotainment center that is non functional. We consider this a hazard to our safety and feel that gm is fraudulently selling consumers defective vehicles knowing this may be a safety hazard.
