Example complaints

“I went to put on my brakes, I first started to stop then my brake pedal went all the way to the floor. I hit a vehicle in front of me. The collision shop that I had it repaired at said the brake lines were rusted. After further investigation I read a lot of complaints about this same defect in chevy and Gmc trucks.”

“I have a 2006 Gmc Sierra with the same ABS issues that are recalled for older vehicles. Abs engages at low speeds when coming to a stop increasing stopping distances. I took it to dealer and they replaced the rear brakes. Truck has only 41000 miles on it, I wouldn't think the rear drum brakes would be worn out. I drove it home last night and to work today. Same problem still exists. Will recall be extended to include my vehicle someday?”

“When I went to start the truck in the morning, I put my foot on the brake pedal and it went to the floor. Got out and saw the brake fluid on my driveway. Examined the truck and found a steel brake line had rusted through and others had significant rust.”

“There is no warning the pedal goes to the floor and you don't stop. I had a 5th wheel trailer hooked to my 2006 Gmc 2500 ext. Cab long bed Sierra p/u with 62,459 miles on it. I was able to stop it with the trailer brakes and a scratch on my front bumper from a tractor trailer that was in front of me. I have owned over 200 cars + trucks since I started driving. I do all my one work on them and I never had a brake line fail, I will be 70 this year. It is ridiculous for an 8 year old truck to have rusted brake lines to fail. …”

“Brake pedal went to floor almost causing an accident before the vehicle came to a stop. Before the service light came on. The service light did come eventually at which time we checked the master cylinder which was extremely low so we filled it thinking that was the problem. The next day we noticed brake fluid dripping and after checking realized that at least one of the brake lines were were rusted through in several places and all of the other lines are terribly rusted and probably on the verge of leaking also. This is a truck that we usually pull our camper with. …”
