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.

YESTERDAY 20TH JULY DEALERSHIP TOLD ME THAT FRONT PASSENGER SEAT AIRBAG MODULE, FRONT PASSENGER AIRBAG PLATE IN SEAT AND SOMETHING ELSE AIRBAG IS WRONG. TOLD ME NOT COVERED UNDER WARRANTY IN WHICH SINCE IT IS A 2018 I COULDN'T BELIEVE IT. THEY SAID BECAUSE HAVE 62,000 MILES IS WHY. I SAID THIS IS A SAFETY ISSUE THEY ACKNOWLEDGED THAT BUT SAID I WOULD NEED TO HAVE IT REPAIRED WHICH WOULD COST $1300 WITHOUT TAXES. I CALLED GENERAL MOTORS AND HAVE A CASE NUMBER. HOWEVER, NOT GM NOR THE DEALERSHIP NESMITH CHEVROLET, BUICK, GMC SEEM TO FEEL THIS SHOULD BE A RECALL OR A SAFETY ISSUE THAT THEY SHOULD BE LIABLE FOR!
