“All of the brake lines are completely rusted out. My wife had a complete brake failure while driving my daughter to school. Brake line over frame leading front to back failed and completely emptied the master cylinder of brake fluid, result car would not stop. This must be made into a recall, as the possibility of a major accident and loss of life is very probable.”
NHTSA complaint #10427003, filed 2011-09, 75,000 miles“I was driving home at night after getting gas in the middle of the gas shortage during the major snow storm in the north eastern united states. As I was approaching a light I pressed on the brakes and it went straight to the floor. I then brought it to a mechanic and when it was placed on a lift they noticed the entire bottom of the car was rusted including the brake lines. They ended up replacing the entire brake line system due to excessive rust.”
NHTSA complaint #10538363, filed 2013-09, 67,000 miles“I was traveling down a city street and went to stop at a red light. I applied the brakes and the pedal was very soft so I pushed a little harder and the pedal went to the floor. I had to swerve into a gas station parking lot to avoid an accident and apply the emergency brake to stop the vehicle. I crawled under the vehicle and saw that there was brake fluid dripping from the floor and the hard lines under the driver side floor. It is getting taken to the dealer tonight to have the issue fixed. …”

NHTSA complaint #10565437, filed 2014-02, 136,000 miles“After stepping on my brakes aggressively to stop for a dog crossing the road. I received a brake stability notice on my dash. Since I was in the middle of the road, I put the car into drive to get over to the side of the road. The car did not slow down after I pumped the brakes, and tried to throw the car in reverse to reduce the speed. I coasted into a parked subaru on the side of the road and because of the rear impact the subaru that I hit pushed into toyota highlander in front of it. Therefore three cars affected by the accident. …”
