The traction warning suddenly comes on then the stability service warning jumps on....automatically lowering my speed while I'm on the freeway driving. When I pull over and turn the car off then turn it back on...the light goes away. This happened several times. Dealership can not find anything wrong. It happens when I hit a pot hole or speed bump

The screen mentions the stabilitrak isn't working and the truck looses power and shuts off. The transmission isn't shifting properly. The truck looses power out of no where al so saying the traction control isn't working. It happens all at random times.

My wifes vehicle which is our family vehicle has had several reoccurring issues. We have brought the vehicle to the dealership several times and have not resolved the problem as it is still on going. The problem does not happen all the time but is extremely scary. While driving the vehicle will alert that you are about to have a collision but there is nothing in front of you just a vehicle to the side of you and will break on its own. This has happened numerous times but the dealership has not been able to replicate the problem. We also had service stabilitrak, traction control off and the service traction control lights come on the dash while driving. When these came on the vehicle started to shake horribly and the RPM's dropped to under 1000 while still going 40 mph. I have also had on a few occasions the backup camera say vehicle guiding lines unavailable while reversing and while driving randomly the vehicle with say park assist off then disappear after several minutes. Just 2 weeks ago I went to start the vehicle and it said service theft deterrent system and would not start until I disconnected the battery and waited a few minutes to reconnect the battery and re-start the vehicle. We brought the vehicle to sheehan GMC in lighthouse point Florida 4 times for these specific issues and received no resolution. After contacting GMC we received no assistance until I filed lemon law which then they sent an engineer who stated after a 2 hour inspection there was no replication of problems and vehicle is operating as normal. This vehicle is a death trap and not safe to drive my family in. I will not purchase another GM product.
