Example complaints
Air bags: “I broadsided a pick up truck that ran a stop sign. Enough damage was done that my vehicle had to be towed and likely will be written off by the insurance company as totaled. I was diagnosed with blunt trauma to the chest wall with contusions. My airbag never deployed.”
NHTSA complaint #10525157, filed 2013-07, 160,000 milesBody and structure: “Chassis is rusting out. Drivers side rear spring shackle, bracket fell off and need to be replaced costing me about $500.00. Mazda b2300 is also a Ford Ranger which also has similar issues. My truck has about 170,000 miles on the odometer. The drive train is strong; idles and runs smooth, does not burn oil.”
NHTSA complaint #11573912, filed 2024-02Brakes: “My Mazda b3000 pickup would not stop at a red light causing an accident. When I engaged the brake the front end shook and then there were no brakes. The day of the accident there was a light rain but I had not driven through any puddles, therefore I don't think it was due to wet brakes as I have been told. Ultimately my brakes did not work, I only have 30k miles on the vehicle, and I will fear driving it once the body has been fixed. I have never had a vehicle that wouldn't stop and I feel there is something mechanically wrong. …”
