Takata recall. Passenger seat, passenger detect sensor (pps) stopped working. No physical damage. Passenger present light says, passenger air bag off. Air bag dash light always on. I checked wiring under the seat and can not visually see any damage to the wiring going to the seat cushion sensor or the seat buckle sensor.
The car traction control failed and the vehicle had the service stability system come on. The abs light was lit and the vehicle would not accelerate or turn easily. The vehicle went into the ditch. This vehicle had headlights prior to the incident with bulbs popping out inside and moisture. After the repairs were done by the body shop the new headlights have had that same problem. The airbags never came out, and there is a message displayed indicating they needed service. It was never addressed by the body shop. Also prior to the incident the steering had an issue causing pain to my shoulder. The diagnosis was wrong after the steering service light remained after a gear replacement and the same issue caused pain. Time passed and the shoulder got worse. There has been 2 wheel sensors with issues. The dealer never told me that there was a special warranty for the timing belt when I bought the car. I am also now having issues with the computer screen. I cannot change the time anymore.
