Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Rear seat belt behind driver does not retract properly. Dealer suggested replacement. Claimed it couldn't be fixed. I have had to replace the rear seat belt on the passenger side twice on this vehicle. The rear seats are used infrequently thus, the rear seat belts are used infrequently. Rear seat belts to be virtually useless three times on the same vehicle seems like a safety hazard to me.”
NHTSA complaint #10100042, filed 2004-11, 78,000 miles“Consumer was able to remove the key from ignition without the vehicle being in park. The consumer stated that she could shift the gear lever to all gears when the key was not in the ignition and engine in an off position. The vehicle rolled down the hill and ran over a mailbox damaging the vehicle and back while the gear lever was still in park. The rear seat belts does not retract and had to be manually pushed back into the mechanism.”
