As I was coming to a stop sign with 2 vehicles in front of me, doing less then 5 mph I stepped on the brake peddle. It actually felt as though the car lurched forward and bumped the car in front of me. I reported it to the dealership they could not duplicate the problem. My insurance company covered the damages but I still had to pay the deductible($500). This problem has occurred on 2 different occasions when I depressed the brakes going around a curve. Have not reported the last 2 but am concerned. Is there anyone else that's experienced this problem????

I bought a 2013 Volt 2 weeks ago. While at the CVS drive through today the car started to beep warning lights when off, brake pedal went to the floor and the car started moving forward. The brakes completely stopped working, no pumping or anything. I made it into a parking space to await for a tow truck and turned the vehicle off. When I turned the vehicle on the error messages were gone and the brake pedal felt solid again. I started to move the car and the errors came back and brakes failed again..

Errors were

"Service StabiliTrak"

"Service Brake Assist"

The experience was scary. I towed it to the dealer. After 2 1/2 days I called the dealer and got a hold of my service rep. He told me that they ordered a new master cylinder from the manufacturer but that it was on back-order and could be a couple weeks. I have read on the forums that others have had this replaced as well. Unacceptable quality management, putting customers and their families lives at risk. Not that Chevrolet has any kind of image problem but they could have at least gave me a comparable rental or something.
