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.

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.

FUEL SYSTEM, GASOLINE:STORAGE

10,000 units potentially affected
The defect: THE FUEL FILTERS WERE PRODUCED WITH AN INCORRECT THREADED FITTING. THE INCORRECT FITTING IS SIMILIAR ENOUGH IN SIZE THAT THE FUEL FILTER MAY APPEAR TO BE CORRECTLY THREADED ONTO THE FUEL LINE.
The risk: REPLACE THE FILTERS WITH THE CORRECT FILTERS.
The remedy: THE IMPROPER THREADING COULD CAUSE A GASOLINE LEAK WHICH MAY RESULT IN AN UNDERHOOD FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.

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.
