“Brakes suddenly gave out. Pedal fell to floor and when I took it to be repaired I was told all the brake lines rotted out. I don't understand this because by vehicle was garage kept. My total bill was $875.00.”
NHTSA complaint #10586332, filed 2014-05, 170,000 miles“Sitting at a stop light the brakes failed. Holding the brake while waiting for the light to change, the pedal all of a sudden went to the floor. When I began moving I had to keep the truck below 30 MPH to allow the brakes to work with increased stopping distance factored in. After about a 5 mile drive home, checked the brakes and noticed a leak from rusted brake lines near the driver's door. Truck cannot be safely driven until rusted lines are replaced. No ability to make a regular stop much less an emergency stop in the present condition.”
NHTSA complaint #10859894, filed 2016-04, 222,000 miles“I have a 2003 truck that is regularly serviced at GM dealerships and another professional shop. I alternate shops to make sure I am getting the best service and making sure any problems are caught before they are serious. I wash my truck on a regular basis always getting the underbody/chassis washed off. So, the vehicle is taken care of and kept up.the incident above luckily happened when I was backing up my truck to connect to a trailer. The brake lines burst under the driver side leaking oil all over when the brakes were applied lightly.. …”
