We recently took the vehicle in for work to be done on it, and the repair shop said that the seat belt tensioner had not been replaced in the vehicle, and the air bag system had been rigged to not trigger the airbag light to come on and that the module on it was bad, which may cause the airbags to possibly not deploy. They let me know that it is illegal for either of these things to be tampered with. …”
