“Lost total braking at red light at busy intersection,45 MPH with the grace of god avoided a broadside hit, just missed a child on a bike, this was caused by a rusted brake line. What happen to the safety back-up in this design ? This is wrong. In so many ways. In the USA we need to hold our safety to its highest. How many will die before this problem is resolved .”

“I was driving down the road with my wife and granddaughter when all the brakes ,I mean all the brakes went, and a service brake lights came on at the same time.I managed to drift to a stop, otherwise we would have hurt someone or been killed. No warning. I had to pay 1900 for the repair which we cannot afford since I am on disability. It still scares us.”

“Brake lines are leaking so I took truck to the dealer and they advised me the lines were corroded and it would cost me $1200. To $1500. To fix and it was not safe to drive. Lucky I noticed the leaking before my brakes failed me. I don't know why this was not recalled and fixed at no cost by GM dealer. Please let me know GM's responsibility here.”

“I was applying brakes and a front brake line blew out. The truck had a tough time stopping almost hitting another vehicle, I had it towed to a repair facility and they replaced the line $300. The repair facility stated to me that it was very common for chevy vehicle to have bad brake lines. To replace the rest of the lines it would cost me $ 900 to $1200. Chevy should of recalled these vehicles for bad brake lines.”

“Pulling out of parking lot and when merging into traffic I pressed on the brake pedal and it went completely to the floor without any braking action. The pedal came back up to normal position and I pressed it again harder the second time while simultaneously shifting into first gear. The pedal went to the floor again but locked up the wheels and the vehicle gradually came to a stop.”
