Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

ON 10/24, 2001, WHILE DRIVING MERCEDES S-420 WITH 65 MILES PER HOUR ON PENNSYLAVANIA TURNPIKE, PASSANGER SIDE WHEEL WITH TIRE AND WHEEL CAP SEPARATED FROM THE CAR AND FLEW OUT TO THE OPPOSITE SIDE OF ONCOMING TURNPIKE. AFTER THE CAR WAS TOWED TO SUN MOTOR CARS, INC. AT 4444 CARLISLE PIKE, CAMP HILL, PA,(717 737-3030) IT WAS FOUND OUT THAT THE 4 BOLTS FIXATING THE WHEEL TO CAR WERE CUT AND SHEARED. AND ONE HOLE WAS RUSTY. THIS MIGHT SUGEST THAT MANUFATURER USED SUBSTANDARD BOLTS WHICH COULD NOT WITHSTAND THE PRESSURE. I HOPE NO OTHER PEOPLE HAD SAME EXPERIENCE LEADING TO THE INJURIES AND DEATH. *AK

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
