“Noticed a puddle of fluid on the garage floor. Investigated and found it to be brake fluid. The entire reservoir emptied on the floor after a day. I had a hole in one of the brake lines under the drivers side. Looking under the truck all the line were terribly corroded and could break at any time . Taking it to my mechanic next week to replace all the lines. 9/1/2015”
NHTSA complaint #10761851, filed 2015-09, 98,000 miles“Brake line burst when I pumped brake pedal prior to start of trailering a horse trailer. Gmc dealer stated brake lines were rusted through. Dealer had inspected vehicle week before during tune-up and did not notify me of rust or issues with brake and fuel lines rusting in GM trucks. I found reported issues with rusting brake lines in GM trucks per my own research. Brake lines are being replaced at my expense.”
NHTSA complaint #10549643, filed 2013-10, 70,000 miles“I had a minor vehicle accident when I applied the brakes they went straight to the floor. I hand my vehicle towed to shop and it was found that the brake lines had rusted thru in the bracket on the firewall.”
NHTSA complaint #10851483, filed 2016-03, 130,000 miles“I drive a company truck during the week and make a habit of driving my Sierra once a week as well. I was going down the driveway to the main road when the pedal fell to the floor. No brakes whatsoever. I used the emergency brake to come to a safe stop. I looked under the hood to realize that the brake lines were rusted and had blown a hole. This truck is not that old and I do not live in a northern state where salt corrosion is an issue. I baby my truck and keep it up. I later did a search on the web an found out that thousands of others are having this issue as well. …”
NHTSA complaint #10644320, filed 2014-10, 174,233 miles“When traveling through an intersection at a green light another vehicle illegally entered the intersection. I saw the vehicle and attempted to stop but when I hit the brakes the pedal went down to the floor and no braking action occurred. I was told I blew a brake line. The car was repaired of the damage from the accident but I had to pay for the brake line repair. After getting the truck back I brought it back to the repair shop for an alignment within a few days. While the repair shop was driving the car in for the alignment a second brake line blew. …”
