Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Seat belts/airbag lights keep coming on. They have replaced the harness in the seat, belt buckle, reset the light and now they say the seat belt module now has to be fixed. I believe this is from the recall that has not been done on the car which is the airbag module. The light came on when you sat in the seat or just driving along”

NHTSA complaint #10991133, filed 2017-05, 50,000 miles
