NHTSA complaint #10031382, filed 2003-10, 31,500 miles“Driving to work, my brake pedal began to get soft but I made it to work safely. At work, I popped the hood a found the brake reservoir was empty. I had not noticed any leaks on my driveway before so I was confused at this leakage. I was able to refill the reservior and tested my brakes at lunch and they seemed better. But before driving home I noticed there was a puddle under the car. I drove home, with my brakes getting softer at each brake application. Once home the leaking continued. The source of the leaks is the brake lines rusting. …”
NHTSA complaint #10189706, filed 2007-05“The contact owns a 1999 Buick Century. The contact was driving approximately 50 MPH when the check engine and track off warning lights illuminated. The vehicle was later towed to a local mechanic where the contact was advised that the ABS sensor and other wires were bound by electrical tape and the fuel and brake lines were corroded. In addition, there were missing plugs which prevented water from entering the vehicle on both the driver and passenger sides. Both the brake line and the transmission were leaking fluids. …”
