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.

HAVE HAD MY VEHICLE AT THE SHOP FOR TRANSMISSION ISSUES SEVERAL TIMES. TWO OF THE TIMES, ISSUES WERE DUPLICATED AND PARTS REPLACED, BUT SAME ISSUES CONTINUE AS SOON AS I GET IT BACK. MY COMPLAINT WHEN I TAKE IT IN IS ALWAYS THE SAME. NORMALLY WHEN I ACCELERATE FROM A DEAD STOP FORWARD OR REVERSE, THE TRANSMISSION MAKES A THUMPING NOISE. IT HAS STEADILY GOTTEN WORSE. A LOT OF TIMES NOW IF I TAKE MY FOOT OFF GAS FOR A SECOND, AT FASTER SPEEDS, AND THEN PUT FOOT RIGHT BACK ON GAS, IT MAKES THE SAME THUMPING NOISE AND SOMETIMES A GRINDING NOISE LIKE IT'S STUCK BETWEEN GEARS. THIS LAST TIME I TOOK IT TO THE DEALER, WAS TOLD THERE WAS NOTHING THEY COULD DO AND WOULD MOST LIKELY GET WORSE AS VEHICLE GETS OLDER.

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.
