What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Tire tread separation on passenger rear side occurred on 8/28/09 in st. Augustine florida. The vehicle was a mazda b2300 (2001). The driver lost control of the vehicle, spun around 180 degrees on i95, went into the ditch & collided into the guardrail on the passenger side.
The frame, suspension, and brake lines rusted through prematurely. The brake lines were replaced all around before 75,000 miles. Before 80,000 miles the truck has been declared non-repairable as the frame and suspension have rusted through at inspection. Truck was lightly used since 2001 and had not hit 80,000.
The entire frame rusted out from under my truck. While driving down the street, the spare tire fell away from the bottom of the truck, ripping off the left side of the bumper. I have been to numerous garages about repair and none will touch it.
Discovered the right rear spring hanger had rusted off the frame of the truck. Further inspection has found the frame is so badly rusted that repair of the spring hanger is not possible due to the overall condition of the frame. Simply put, the frame has rotted and pieces fall of as you drive.
When the cruise control was activated the vehicle suddenly accelerated on its own. The contact was able to slow the vehicle down when he depressed the brake pedal. The vehicle was taken to the dealer for diagnostic testing.
The contact stated that after taking the vehicle in for regular service, the technicians advised him that the frame and the brake lines were severely rusted. The vehicle was repaired for the frame. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 90,000.
He also stated that the check engine light was currently illuminated. He had not taken the vehicle to the dealership or called the manufacturer to-date. The vehicle had not been repaired at the time of the complaint. The current mileage was 166,197. The failure mileage was approximately 165,500.
While driving between 2-3 mph out of a parking lot, the brakes failed. The contact had to apply the parking brake in order to stop the vehicle. The dealer stated that there were no recalls for this failure.
