Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Tried to stop at red light ,and the brake pedal went all the way down I had to jump the curb not to hit another car. My husband came and looked at the truck and saw the brake lines were rusted through and fluid was coming out. He put a whole can of brake fluid in so that I could move the truck down the street to a service center. Again the repair man said all the brake lines are rusted out. We repaired one a summer ago with the same issue.”
NHTSA complaint #10574775, filed 2014-03, 94,000 miles“I have a 2001 yukon Denali that has the problem detailed in investigation # pe05020. The ABS activates at low speed. I had brought this to a dealer for repair. They fixed the drivers side but the problem persists. They assume the pasenger side ABS sensor now has a problem. I have also had the front brake drums replaced twice on this vehicle and it only has 21,000 miles on it.I have had an accident with thhis problem in the winter.”
NHTSA complaint #10129076, filed 2005-07, 15,000 miles“We have noticed that our cars anti-lock brakes activate when we get to a low speed of about 5 MPH, causing our stopping distance to be increased, which almost caused us to rear-end another car. We bought the car used about 3 months ago and noticed this problem on thanksgiving of this year. There is a recall for this problem through NHTSA campaign id number: 05v379000. We called Gmc hotline and they say it isn't covered by the recall. I see the recall has been revised several times already. Can anything be done before an accident does occur?”
NHTSA complaint #10438646, filed 2011-12, 159,000 miles“Brake line ruptured while driving in the mall parking lot - pedal went straight to the floor, thankfully still had some (tiny) brake left to stop. Looked under the truck and saw brake fluid dripping underneath. All brake lines look completely rusted out making the vehicle undrivable.”
NHTSA complaint #10494460, filed 2013-01, 155,000 miles“Parking brake never works. Had complete system replaced at dealership 3 years ago. Did not improve the stopping capabilities. Other individuals with the same vehicle identify have explained that this is a problem they also experience. I am afraid that there is no backup brake system in the event of a primary brake system failure.”
