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.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV)

Sep 21, 1978
218,500 units potentially affected
The defect: THE INVOLVED VEHICLES CONTAIN EMISSION CONTROL SYSTEMS THAT UTILIZE A PULSE AIR REED VALVE TO PERMIT AIR FLOW FROM THE AIR CLEANER TO THE EXHAUST MANIFOLD ON NEGATIVE PRESSURE PULSATIONS. THESE REED VALVES MAY FAIL UNDER COLD WEATHER CONDITIONS, CAUSING A BACKFLOW OF EXHAUST GAS INTO THE AIR CLEANER AND FUEL INDUCTION SYSTEM ON POSITIVE EXHAUST PULSES. THIS CAUSES AN OVERLY RICH AIR/FUEL MIXTURE, REDUCED FUEL ECONOMY AND REDUCED ENGINE PERFORMANCE. CONTINUED VEHICLE OPERATION MAY RESULT IN ENGINE STALLING OR OVERHEATING OF THE EXHAUST SYSTEM.
The remedy: THE DEALER WILL REPLACE THE PULSE AIR SYSTEM REED VALVE AND SILENCER WITHOUT CHARGE.

Aug 7, 1978
400,000 units potentially affected
The defect: THE WINDSHIELD WIPER DRIVE LINKAGE ON THE AFFECTED VEHICLES MAY FRACTURE DUE TO METAL FATIGUE AS A RESULT OF REPEATED FLEXING OF THE DRIVE ARM ACROSS A STRESS SENSITIVE AREA. THIS CONDITION WILL RENDER THE WINDSHIELD WIPER SYSTEM INOPERATIVE.

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.
