What owners say
Without warning the brakes failed. Vehicle was in motion at time of failure, vehicle could not be stopped and at 30 MPH ran through the red traffic light at a busy city intersection. Fortunately, no accident occurred. Vehicle had to be towed to dealership. Dealer repaired vehicle. Invoice stated: "brake line wore through from steering column rubbing on flexible section."
The vehicle's engine shuts off while driving. Without warning. This happens at various speeds. Loss of brakes and power steering occurs after engine shuts off. This has happened on several occasions at varying speeds. Speed varying between 30 MPH to 70 MPH. Engine will restart (be turned back on after wait time at the ignition) and drive following these incidents, however incidents reoccur. Also upon taking it to a gmc chevrolet dealership for inspection, service department was unable to find any "codes" related to this. Fuel pressure was tested in stationary position and in driving and fuel pressure appeared fine. Dealership noted no issues. Upon picking the vehicle up after inspection the engine cut out again while driving on the way home, again without warning. Incidents occurred on dry roads. Outside temperatures have varied from 50 f to 90 f and length of drive time has also varied from three hours at time of occurrence to only minutes after start up. Incidents happen at random and not every time vehicle is driven.
Steel brake lines have rusted through, causing leakage and total brake failure during application. Calipers and bleeder valves also rusted, preventing new brake lines from being re-attached.
I was driving with my 14month old baby in the car and all of a sudden I had no brakes at all. My parking brake couldn't stop me either so I put the car in neutral and then forced it into park so I didn't crash. The brake lines are completely corroded and I didn't have any notice or idea until the brakes were already gone.
Was driving about 30mph and hit the brake pedal, the brake pedal went to the floor and we ran into a trailer. The brake lines were rusted so bad that they busted, and caused the brake fluid to leak out. The estimate to repair the brake lines alone is $2800.
A dog ran out in front of me I applied my brakes and the pedal went to the floor had it checked at bale chevrolet in little rock ark. Wanted to charge me 6800.00 to repair had it towed back to il. Where I live that cost was 500.00 besides 200 miles that was covered by aaa I,m a 62 yr old woman had my grandchildren with me in little rock ark this experience was the scariest time in my lifetime no warning just all of a sudden no brakes in the worst traffic ever. The money spent on this trip was very expensive not to mention the stress.
Due to corroded brake lines, my brakes failed, causing a crash.
A vehicle in front of me stopped short because a car was making a left turn in front of him. I applied the brakes. I was able to stop but immediately there was a white smoke coming from under the hood and the traction control and brake lights came on. I went to drive a few feet and tried to stop when I realized I had no brakes at all and the white smoke was still coming out. My vehicle was towed to a shop. The brakes line failed because of corrosion. The brake fluid was spraying onto the exhaust manifold creating the white smoke.
The problem: brakes failed while vehicle was running. After a hard brake at a stoplight and driving briefly, the brake pedal went straight to the floor barely stopping the vehicle. Brakes were extremely mushy to non-existent at times. Repair work: local gmc service department indicated the brake line had rusted out and they replaced it for close to $1,600. Per the invoice repairs included: brake system repair/labor, brake flush kit, pipe kit and fluid. (when asked about brake line issues later, the dealership stated they have never heard of any problems regarding them with gmcs.) how it happened: while driving with my wife and children in the vehicle, I had to break hard when I came around a bend to a red stoplight. Though the brakes worked, they felt like they were giving just a little after I finally came to a stop. We preceded another 15-miles with no incident and pulled into restaurant drive-thru. While sitting in the drive-thru lane with the vehicle in gear and my foot on the brake, all of a sudden my foot went to straight to the floor and the vehicle jumped forward. Thankfully there was enough space between my vehicle and the vehicle in front of me so that I didn' hit them. I immediately shifted it out of gear to stop the vehicle from moving forward. At this time I noticed a warning light had come on indicating to check brakes and that the ABS was off. I tested the vehicle in a nearby empty parking lot to see if it was still drivable and the brakes appeared to have only a little bit of 'stoppage' though the pedal was to the floor. I realized it took 50-100 yards to stop the vehicle with brake fully pressed and no gas when we were going 20-25 m/h.
