Brake failure. Metal brake line between master cylinder and caliper developed a leak due to corrosion of the metal brake line. Mechanic said all metal brake lines were rusted and corroded and needed to be replaced. I understand there is an investigation underway on these faulty lines. The replacement of these lines was very expensive and was definitely a premature failure in my opinion. Luckily my 20 year old son noticed the brake pedal was going to the floor while on the interstate and was able to safely exit the highway. If the line would have failed a few minutes earlier, he would have been in a crash.

While making a sudden stop, a hydraulic line serving the front brakes ruptured causing complete loss of front brakes. This is the third hydraulic brake line failure on this vehicle. The first two lines to fail were on the rear axle. All of the remaining hydraulic brake lines are heavily rusted and pitted, they all are at risk of failure at any time. This problem is widespread on this year and model vehicle. It poses a serious risk to the drivers and to the persons and property of others. Every one of the owners should be notified that their vehicle may require replacement brake lines. Whose responsibility it shall be is up to NHTSA, but the need for information is great. This is a heavy weight vehicle for ordinary consumer use. Most such users are unprepared for a brake failure of this kind. Interestingly, GM does not offer replacement parts. Precision formed lines are available on the aftermarket. The local Chevy dealer uses non-corroding copper-nickel replacement line, and fabricates the lines locally. The same brake line metallurgy was used in high end european cars (Volvo and Porsche) beginning in the 1980S.

While driving on the highway at 55mph I was near my exit and activated the brakes and the pedal went to the floor. I was fortunate to have the room to change lanes and pass my exit and downshifted to slow and eventually stop. I had tried to apply the parking brake and the cable snapped on the spot. After getting the car to a mechanic I was told that every brake line was corroded and most were failing. The mechanic also said it isn't recommended to replace just the leaking lines because once the pressure is restored, the remaining lines would then likely fail. The vehicle is currently in the shop and I am waiting for what I am sure will be a sizable repair bill.

ABS system activated and prevented the car from slowing down. Lifted my foot off the brake and tried again, it seemed to work. This has happened multiple times and ABS system activates incorrectly at about 5 miles per hour.

Brake warning indicator light illuminated. Noticed fluid low. Checked and found leak in brake line due to corroded/rusted line.

- Wilmington, DE, USA

Pulling up to a stop sign I attempted to brake, but the brake pedal dropped to the floor and only offered a minuscule amount of stopping power, I limped 1.5 miles home using downshifting. Brake lines are completely rusted out and apparently burst, brake fluid container under hood was completely empty. I cant even think what would have happened if I had been on the highway and they failed.
