Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I had been driving on the expressway, I exited and stoped at a drive up window. As I pulled up to the window my brake peddle went to the floor, I had to put it in neutral and use the emergency brake to get the car to stop. After inspection I found that a line within the cluster of four had failed under the drivers side front door. All the lines needed to be replaced due to severe rust.”
NHTSA complaint #10575831, filed 2014-03, 140,000 miles“The brake light came on in my car and when I took it in to the mechanic, I was told the brake lines were corroded. Brake fluid was leaking through the lines and if I had driven for even another hour, I would have had no brakes. I had the lines replaced, which had to be custom built. The repair cost me $1188.”
NHTSA complaint #10566333, filed 2014-02, 105,226 miles“The brake tubing mounted along the frame towards the ABS and away from the ABS are very rusted flaking etc. They have not busted jet but could any moment, I'm having them changed. As many people had busted tubing for me it is a safety issue, I'm an mechanical engineer and I understand the defect.”
NHTSA complaint #10630442, filed 2014-09, 168,000 miles“While operating the vehicle on a highway I pressed the brake pedal and suddenly the brake pedal sunk and I lost brakes. I nearly lost control of the vehicle and almost drove into a guard rail. After further inspection I observe the front drivers side brake was corroded causing it to break. This appears to be an issue with Gmc and the company should be required to rectify the situation. Using stainless would prevent incidents like these and possible injuries or deaths.”
NHTSA complaint #10717680, filed 2015-05, 178,700 miles“Had just backed our bay boat into it's spot after hauling it on i95,the blue route and pa turnpike .when I released the emergency brake to pull away from the boat,the service brake light appeared,and immediately lost most of my braking power .I found that one of the brake lines had ruptured .if this had happened on the highway ,towing the boat,it would have been catastrophic. I didn't realize how common a problem this has been until I found untold numbers of other owners on the web with the same issue.”
