I started receiving an error message that driver assist is reduced drive with car at 50k miles (i have an onstar diagnostic report and phone call made that day). It shut my car down and activated the parking break. I called Onstar at that moment it happened and they found nothing wrong with the car. It continued to happened several times after and each time I took it to the dealer they were unable to diagnose the problem. One time I was told there was a bulletin on it from GM, but not for the year of my car so they were not able to make the repair. When it finally started giving me the error all the time, they finally found it was the thermostat - $1600 and GM would not cover the part under warranty because I now had over the warranty miles even though it happened and was reported prior to that point. I have several people tell me with the same vehicle they too are having the problem - and it is costing each consumer $1600. GM knows it is a problem because it is all over the internet. There should be a recall and our costs reimbursed if we have had to make the repairs on our own.

When the vehicle is already in motion, it automatically shifts out of drive and I am left in the middle of the road unable to accelerate for a few seconds until the vehicle automatically shifts back to drive. This happens after pulling out of my gravel driveway which is a slight incline, and onto a highway. The cause is unknown.
