Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was traveling on a two lane county road located in oldham county kentucky and upon approaching a curve, I attempted to apply the brake to slow the vehicle but the brake pedal went to the floor and provided no braking action (severely rusted brake lines burst and resulted in total brake failure ). The curve was followed by an intersection with a stop sign in my lane. Luckily there were no vehicles in front of me and no opposing traffic at that moment, which enabled me, through the use of gears and the emergency brake, to get the vehicle stopped just beyond the stop sign. …”
NHTSA complaint #10557441, filed 2013-12, 177,880 miles“2003 Gmc Yukon Xl Denali brake lines rusty and burst while wife was driving and lost brakes. This caused a very dangerous situation. About a year ago the dealership replaced several brake lines due to the same problem. Also they replaced the calipers due to rusted bleed valves. They are using substandard materials and making a very dangerous situation for people that drive GM vehicles.”
