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 Jul 7, 2008
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.

ON 3/22/2012 WITHIN A FEW HUNDRED FEET OF LEAVING A DRIVEWAY, THE RIGHT WHEEL SLOWLY SEIZED (WITHIN 100 FEET), ABS AND ESC WARNINGS APPEARED AND THE CAR BECAME IMMOBILIZED. THE CAR WAS FLAT-BEDDED TO THE DEALER FOR REPAIR. THE RIGHT STEERING KNUCKLE AND RELATED WHEEL/PARTS WERE REPLACED. ON 6/23/2012 AT ABOUT 25 MPH, THE ABS, ESC WARNINGS SHOWED, THE CAR PULLED TO THE RIGHT ON BRAKING. THE CAR WAS PULLED OVER AND PARKED, AND AGAIN FLAT-BEDDED TO THE DEALER. THE LEFT STEERING KNUCKLE AND RELATED PARTS WERE REPLACED. IN SHORT, THE RIGHT STEERING KNUCKLE FAILED, AT LOW SPEED FORTUNATELY, AND THREE MONTHS LATER THE RIGHT FAILED IN THE SAME MANNER. HAD THESE FAILURES OCCURRED AT HIGHER SPEED, THEY WOULD HAVE PRESENTED A SERIOUS STEERING CONTROL PROBLEM. *TR

NOT A FAILURE, BUT I NOTICED A SIGNIFICANT LABELING DISCREPANCY ON MY 2009 MERCEDES BENZ SLK300. THE TIRE LABEL ON THE DRIVER'S DOOR INCORRECTLY LISTS THE OEM TIRE SIZE AS 205-55-16 FRONT AND 225-50-16 REAR. THE VEHICLE IN REALITY IS FITTED WITH 225-45-17 FRONT AND 245-40-17 REAR; THESE ARE NOT OPTIONAL TIRES/WHEELS EITHER - THEY ARE THE STANDARD SIZE AND WERE LISTED ON THE WINDOW STICKER AS SUCH. THEREFORE, IT IS ALSO NOT CLEAR TO ME IF THE SIZE DISCREPANCY ON THE LABEL ALSO MAY MEAN THAT THE LISTED TIRE PRESSURE DO OR DO NOT APPLY TO MY VEHICLE. *TR

They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

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.
