I bought my car [XXX] it had 7 miles. I loved my car. Then in January 2021 things just went crazy. It started with park light on. My forward brake assist warning didn’t work, my back up camera in and out . My braking and stability were on and off. Then weird codes like. Engine at half power, unable to shift soon and speed control out. Then if I hit a bump message went away and speed control back on. I’ve taken care into another GMC dealer because dealer I bought my car at , closed up and took off!!
While in motion- blind spot sensors turn on when they should not and vice versa. Traction control has failed multiple times while driving. Predictive braking has activated improperly multiple times while driving. Cameras went out and then battery completely died. Was told fixing battery would fix vehicle. This has proven to be untrue. Vehicle is currently in for service for third time. Remains under warranty, as I have had it three months.
