The alternator failed randomly while driving down the road. The vehicle only has 26500 miles. There was no lights on prior to the car stalling. When it failed my whole car started to flash every warning at the screen to me. My car then stopped working and I barely was able to coast into a parking lot. Luckily I was not on the highway and no one was behind me when the car stopped working. The problem was confirmed by the dealer it was the alternator. What sucks though is that the alternator killed the battery. The battery is not covered by warranty so it is $507 to replace a battery.

This vehicle has completely lost power and stalled on the freeway twice. The first time, I was with my wife and children when it happened on the highway. The vehicle stalled in the far right lane of traffic and it wouldn't restart. We had to risk our lives and push the vehicle off the freeway and onto the shoulder while other vehicles raced by. We are fortunate that we did not die or become seriously injured. The second time the vehicle stalled on the highway, my wife was crossing the highway and the vehicle once again lost all power and shut-off. She is fortunate that she was not killed in a T-bone collision. The first time, there was a dash warning stating to SERVICE ESC. The second time, there was no warning lights or dash illumination of a problem beforehand. The vehicle has been taken to the Chevrolet dealership twice. They ran a diagnostic and stated the starter was pulling too many amps which caused the vehicles fuse block to blow, resulting in total failure of all vehicle components. Total repair cost for first repair was approximately 1,000 dollars. We are awaiting the service advisors diagnostic for this second incident. The first repair is covered under a 2 year unlimited mile warranty so hopefully when they replace the starter and fuse block this time, they will also find the root cause of the problem. I feel as if our lives and well-being are in jeopardy since the first incident and we no longer feel safe driving this vehicle which has stalled twice during highway conditions. I am confident that we will no longer be GM consumers due to these life risking incidents.
