Air bags
134 reports3 crashes1 related recall
“WHEN ADJUSTING THE DRIVER AND PASSENGER SEATS, THE AIRBAG LIGHT ILLUMINATED. AFTER RESEARCHING ONLINE, I CONDUCTED TROUBLESHOOTING.

Seats
18 reports1 fire
“THE PASSENGER SEAT OCCUPANCY MAT WAS REPLACED BY RECALL ON 10/28/2016. ON 10/2018 I NOTICED THAT WHEN THERE IS A PASSENGER IN THE SEAT WITH THEIR SEAT BELT ON THE AIR BAG WAS OFF, IN 1 WEEKS TIME THE PASSENGER SIDE SEAT BELT LIGHT WAS ON ALL THE TIME AND THE AIR BAG IS OFF ALL THE TIME WITH OR WITHOUT SOMEONE OCCUPING THE SEAT. REGUARDLESS IF THE CAR IS IDILING OR GOING DOWN THE RODE. AT LEAST BEFORE THE RECALLED MAT SENSOR WAS REPLACED THE SEAT MAT SENSOR WORKED MOST OF THE TIME. NOW IT DOES NOT WORK AT ALL. I TOOK IT TO THE DEALERSHIP AND THEY TESTED THE OC3 MAT (PASSENGER SIDE MAT SENSOR) AND SAID THERE ARE MULTIPLE CODES FOR THE OC3 MAT AND THEY FOUND INTERNAL FAULTS AND IT REQUIRES REPLACEMENT AGAIN. THEY SAID THIS RECALL IS NO LONGER UNDER WARRENTY AND I NEED TO PAY OVER 1500.00 TO HAVE IT REPLACED. IT IS UNSAFE FOR ME TO HAVE A PASSENGER IN MY CAR IF WE GOT INTO AN ACCIDENT THEIR AIRBAG WOULD NOT BE ON, THERE FOR THEY WOULD HAVE NO AIRBAGS TO DEPLOY TO TRY AND PROTECT THEM. HOW IS THIS MY FAULT? THEY REPLACED MY MAT SENSOR WITH ANOTHER FAULTY ONE THAT IS WORSE THEN THE FIRST ONE. HOW LONG ARE THE WARRENTIES FOR RECALLS AND THE PARTS REPLACED? I HAVE THE…”
