“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.”Owner report · Air Bags · Jan 2025
