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.

Latest Aug 27, 2007
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.

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.

THESE LEAKS START AS PIN HOLES AND THEN GROW SO MILLIONS COULD BE DUMPING GASOLINE ALL OF OUR ROADS THAT IS FINDING ITS WAY INTO OUR AIR AND WATER. THIS PROBLEM IS AS SERIOUS AS THE GAS STATION TANKS OF YEARS AGO AND FOR SOME REASON IT IS GOING BY UNNOTICED. I WOULD LIKE A RESPONSE TO THIS COMPLAINT.
