There are 2 owner-reported air bags & restraints complaints for the 2018 Chevrolet Sonicin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2018 Chevrolet Sonic. The contact stated that while a 95-pound passenger was seated in the front passenger’s seat, the air bag system was deactivated. The vehicle was taken to the local dealer who was unable to determine a failure and indicated no failure was found. The manufacturer was notified of the issue. The failure mileage was 15,000.
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.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
