Most Recent Complaints
I was driving and parked the car at the store. After checking out I went to the car got ready to leave and started backing out and the car would not turn to the left at all. I took it to the shop and was told they do not see anything wrong with my car but a steering message is coming up.
Passenger side front seat. When occupied, airbag sensor located inside the seat is malfunctioning. My husbands safety is at risk when he's in the car. He tries moving the seat up, back, etc. Sometimes works and the airbag sensor works. We are fearing that if there were any accident or need, that his life would be in danger if the airbag didn't deploy. This shouldn't be at the consumers expense as this is a safety issue. This has been ongoing for over 6 months.
