Recalls, owner-reported complaints, investigations and safety data

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.
0
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 May 15, 1979
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.

STEERING: STEERING WHEEL/HANDLE BAR

Oct 4, 1978
32,000 units potentially affected
The defect: THE LOWER STEERING SHAFT ASSEMBLIES CONTAIN COUPLING RIVET PINS WHICH WERE NOT RIVETED SECURELY ENOUGH DURING MANUFACTURE. CONSEQUENTLY ONE OR BOTH OF THE PINS COULD LOOSEN FROM THE FLANGE OF THE FLEXIBLE COUPLING DURING VEHICLE OPERATION. IF ONE PIN IS LOOSE, FREE PLAY WOULD RESULT. IF BOTH PINS WORK LOOSE, LOSS OF STEERING CONTROL WOULD OCCUR. ALSO, THE SHAFT ASSEMBLY MAY NOT CONTAIN A METAL REINFORCEMENT BETWEEN ONE OR BOTH OF THE RIVET PINS AND THE RUBBER FLEXIBLE COUPLING. AS A RESULT, THE RUBBER FLEXIBLE COUPLING COULD TEAR AND PRODUCE A NOISE OR LOOSE FEELING IN THE STEERING SYSTEM.
The remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE STEERING SHAFT ASSEMBLY, WITHOUT CHARGE TO OWNER.

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.
