Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Similar to recall campaign #wqk-47 the hard brake line near my gas tank has corroded and leaked all of my brake fluid. Had I been on the highway this could have been catastrophic. The vehicle was in motion, I noticed the brake pedal was traveling farther than normal. When I got home, there was almost no braking ability left in the car, pedal went to the floor. Checked master cylinder, it was empty, added fluid, pressed on brakes, could hear the fluid leaking out. Checked around car to find fluid. This is a common problem on Subaru's and there is a recall for newer wrx's for the same issue.”

“Hello, I've been having extreme problems with the antilock brake system in my 2004 Subaru Impreza wrx. It'll kick in at unneeded times, where I will lose control of the car and the car will continue to lurch forward. This can be a frightening experience, especially if there's a car in front of me. In the winter, I have to pull the ABS fuse, which believe it or not, actually helps my braking distance. If I leave the ABS enabled and hit a patch of ice, I'll lose total control of the brakes and continue to glide. …”

“Driving south on south dixie highway traveling at 45 MPH. Upon noticing the red light the brakes were applied. When the brakes were applied there was no response from them at all. I had to redirect the course of the car to avoid hitting other cars at a red light. As I turned to the right I came upon a curb and the front left tire as well as the left rear tire hit the curb. The front suspension of the car was damaged. The car was not driveable after the accident. It was towed to bird road Subaru in miami. I have been feeling fluttering in the brake pedal for 2 days prior to the episode.”

“Metal connector (that is under the car chassis) joining the brake pipes (lines) for the rear brakes rusted through. With the rusted connector, brake fluid leaked through the holes resulting to brakes not to engage and stop the vehicle when the brake pedal is stepped on. Brake pedal would bottomed all the way to floor when it is stepped on. Failure of the brake connector almost resulted into the rear ending of another vehicle. Picture of the rusted connector is available upon request.”

“2004 Subaru Impreza wrx - during braking, if a bump or rough piece of road is encountered, the brake pedal goes limp, drops to the floor, and brakes cease to function until pedal is released and brakes reapplied. Re-application of the brakes resume full functionality.”
