“While under vehicle to replace gas filter it had become evident to me that the brake lines where they enter the ABS unit were fairly rusted. As I investigated further to areas not easily visible I had discovered that all the hydraulic brake lines are extremely rusted and imminent failure is evident. In mentioning this to a friend he suggest I check on line as he had heard of this problem. …”

NHTSA complaint #10498601, filed 2013-02, 75,000 miles“When applying brakes, pedal unexpectedly went to floor & barely avoided collision.

NHTSA complaint #10328143, filed 2010-04, 59,990 miles“I was driving on 58 west in stuart va when we came around a curve and an 18 wheeler was broken down in the middle of our lane. Two vehicles were stopped behind the truck. I quickly applied the brakes and the pedal went to the floor. I was able to maneuver between the stopped traffic and the oncoming vehicle in the opposing lane to avoid a crash. A brake line had blown causing the brake failure. I had already experienced brake failure in another GM model, and was questioning how it was possible that one person could have two separate brake line failures on two separate but similar vehicles. …”
NHTSA complaint #11110963, filed 2018-07, 176,000 miles“I recently experienced a total brake failure after driving to the grocery store today. Yesterday, I realized that to stop, I had to press the brake pedal almost all the way to the floor. I knew something was wrong because my brakes had been working just fine. Today I noticed the same problem and reported it to my boyfriend, who conducted a visual inspection at the brake lines and underneath the driver side seat, brake fluid was leaking out rapidly and was puddling underneath the vehicle. Had I not stopped, I would have been in a serious accident. …”
