In 2007, with a little over 50,000 miles on my car, the airbag light came on. I went in to the dealer and they said it was a loose wire and reset it. Since that time, I've had six other incidents up through 2014 with the airbag light coming back on and every time they've reset it, it has come back on. I have even had a module replaced but it did no good. The last time I went in, they wanted to replace the pad assembly for $1,000 but wouldn't guarantee it would work. They also said it might be the harness but that part couldn't be obtained. They also said they couldn't guarantee that the airbags would work!!! I have looked at other complaints from several websites and see that there are are dozens of other people with the same problem. This is a serious defect and should be recalled. I have no airbags. My car has been in a minor traffic incident where the airbag probably should have deployed when the car hit the curb but didn't. This is very dangerous.
Airbag wire harness is worn down due to it being located under drivers seat,causing the airbag light to come on and either intermittently stay lit or remain on continuously. Therefore, there is no way to know whether the airbags will deploy or not according to the service rep. The repair is not covered under extended warranty, even though it is a vital piece of safety equipment, and due to poor design it is regularly damaged. I had this issue addressed in 2005, it occurred occasionally after that until last year when the light came on and stayed on all the time. I have been on the internet and there are many complaints about this very same issue occurring with this vehicle dating from 2001, when there was a recall issued, all the way to 2006 when the model was replaced by a different one. According to the remarks, people have had collisions where none of the airbags deployed , or the curtain airbags didn't. There also was a recall in canada. How can a manufacturer get away with such poor quality design for such an important piece of equipment?.
The air bag light stayed on after starting the car - all else seemed ok. I called the dealer and he said it was not important that a connector had probably just come loose and that the air bag would probably still work if needed. When I took it to the dealer he removed the driver's side seat and said he found a broken wire and repaired it - at a cost of about $56 - for a car that has a "bumper-to-bumper" warranty. It was suggested that we must have put something under the seat that caused the wire to break when the seat was moved - this seat automatically moves every time the car is started and stopped. About six months later the same thing happened again. This time it was the passenger's seat that had a broken wire under it. This seat is moved less frequently, but it is a power seat. As far as I know the only thing under that seat was a box of tissues. Again I was required to pay for the repair. I believe this to be a design defect in that anything that is allowed to get under the seat will cause this wire to be severed and prevent the side air bags from deploying. I have never had a car that had any problem with items under the seat. Also this design has a sort of "pan" or depression under each seat that traps any loose article left on the floor when the car is stopped and it slides under the seat. It never slides back out when accelerating. This seems to just make the problem worse. I do not believe that any normal item left on the floor of the car should cause this damage and debilitate the air bag system.
