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.

WHEN THIS CAR STALLS IT WILL FIRST NOT HOLD A STEADY IDLE. THERE ARE OTHER TIMES WHEN THIS CAR WILL BE WATING ATA A LIGHT AND THE IDLE WILLL KICK UP TO OVER 2000 RPM. WHEN THIS HAPPEND THE ENGINE WILL TRY TO ENGAGE AND THE CARE WILL LURCH FORWARD. THE STALLING PROBELM HAS BEEN ONGOING SINCE THE VEHICLE WAS NEW. DURING THE WARRANTY PERIOD THIS WAS ADDRESS BY A DEALER IN DAVIS, CA. AT THE TIME THE DEALR SAID THIS WAS HAPPENING BECAUSE OF A FAULTY "PROCESSOR" IT WAS REPLACED AND THE CAR RAN OKAY FOR A FEW MONTHS. HOWEVER, THE PROBLEM RETURNED. I DID NOT CONTACT THE DEALER AGAIN ABOUT THE PROBLEM. THE WARRANTY PERIOD EXPIRED . THIS PROBLEM CONTINUED. I LEARNED TO LIVE WITH IT AND DRIVE THE CAR. OVER THE YEARS VARRIOUS MECHANICS HAD LOOKED AT THE CAR AND ATTEMPTED TO MAKE ADJUSTMENTS TO CORRECT THE IDLE, BUT THE PROBLEM ALWAYS RETURNED. I THOUGHT THIS PROBLEMS WAS UNIQUE TO MY VECHICLE, BUT I AM AWARE OF A JUDGMENT AGAINST FORD IN A CALIFORNIA COURT IN WHICH VEHICLES WITH THE EFT SYSTEM HAVE BEEN KNOWN TO STALL. THIS REPRESENTS A SIGNIFICANT SAFETY ISSUE AND I WOULD LIKE TO SEE A RECALL ISSUSED SO THAT FORD CA REPAIR THESE VEHICLES REGARDLSS OF AGE.*AK
