THE PASSENGER SEAT BELT DOES NOT CLIP OR WILL COME UNDONE AT ANY GIVEN TIME. I MADE THE DEALERSHIP AWARE OF THE CONCERN WHEN THE VEHICLE HAD APPROXIMATELY 39,000 MILES. THEY STATED THAT SINCE IT WAS OUT OF WARRANTY IT DID NOT QUALIFY FOR PRODUCTION DEFECT. THIS IS A SAFETY CONCERN THAT COULD ENDANGER THE LIFE OF A PERSON IF WEST BELT FAILS DURING A CRASH.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Chevrolet Sonic verdict →
