Brake System Failure 62 MPH Top Speed Service ESC Service Brake Trailer System These warnings appeared on 04/30 and my brakes became extremely hard to use to stop my vehicle. I had my two young children in the car, I was able to go up hill and shift it into park after driving 15 minutes basically with no brakes. It was towed to Hendrick Chevrolet, where they replaced the master cylinder. On May 5th I was driving the car and the service brake assist light came on with the message. I then had it towed to Hendrick where it stayed until July 28th. The dealership stated that it was an external leak in the master cylinder. Now for the 3rd time the brakes are making a squealing noise and the service brake assist light is on again. I do not feel safe in this vehicle.

Vehicle lost all braking capability while in motion. Vehicle rolled to a stop with no brakes with warnings for brake system failure, no front collision active. Upon restarting the vehicle the warnings didnt not go way for 1hr. 2 hours later the warnings cleared from the information system but codes remains. Vehicle was taken to Uptown Chevrolet, Slinger WI and was informed of a bad battery as the "cause" of the issue. A bad battery should not result in the loss of braking capability on any vehicle!

Unknown but there was many lights on at the time of brake failure. I was driving home from Florida to NJ with my four young children in the vehicle on a 65mph highway when all these lights came on, the brakes completely stopped working and it told me it was reducing speed to 62mph for safety because the brakes were failed. It also stated service svc. By the grace of god I was able to off-road it a bit to get it to slow down to a stop. The second time it happened was in my driveway parked. Inbetween the two incidents I brought my vehicle for regular service and asked them to look at the brakes again for me as this is a major safety concern as well as my transmission slipping and they complete refused and only changed my oil.
