How to read this file. Complaint records are unverified owner submissions to the federal safety agency. Counts are raw, not adjusted for sales volume or vehicle age. Recall campaigns apply to the model; only a VIN check shows whether this car is affected or repaired. Parts shown are named by an editorial note or listed as a search directory; none is a diagnosis. Full methodology.
Fault profile
Complaint-component records on this vehicle, grouped by family. A complaint naming two systems counts once in each.
Complaints are owner-reported and not verified by the agency.
When it fails
The timing of this vehicle's reported failures, from the complaint file itself. A cluster tells you what to expect and when; it is shaped by reporting behavior as well as by the vehicle.
Vehicle age when the failure occurred
Years between the model year and the owner's reported failure date. Based on 852 of 855 complaints with a usable failure date.
Odometer when the failure occurred
Owner-reported mileage at failure, in 20,000-mile bands. Based on 249 of 855 complaints reporting a plausible odometer (500 to 500,000 miles; unverified).
Known issues
The component families with the most complaint records against this vehicle. Counts, crash and fire figures belong to the whole family, not to any single named issue. Parts listed are related system parts, not a diagnosis.

Recall campaigns
Safety-recall remedies are normally provided at no charge. Under US federal law the mandatory free remedy applies when the vehicle was no more than 15 years old at the time the defect was determined; manufacturers often cover older vehicles voluntarily. Canadian rules differ. Confirm eligibility with the manufacturer using the VIN. Each campaign number links to the federal record.

Before you buy this vehicle
A test-drive checklist generated from this vehicle's own complaint and recall record.
- Sit in it with the engine off and test everything that has a switch.Windows, locks, lights, the cluster, the radio. Electrical faults are this vehicle's story and the hardest to see on a drive: an intermittent no-start waits for the second week of ownership. Ask for the battery's age and whether any control module has been replaced.
- Cold-start it yourself and listen for the first thirty seconds.Knocking, ticking that fades as it warms, or blue or white smoke on startup are the sounds of this vehicle's engine cluster. Check the oil level and the coolant color, and ask whether the engine or its head gaskets have ever been out.
- Drive it from a dead stop, twice, on a hill if you can.Shudder, hesitation, or a lurch under light throttle is how this vehicle's largest complaint cluster shows itself. Then ask for the transmission service history in writing; repeat repairs are a pattern, not a fluke.
- Run the VIN against open recalls before you negotiate.This vehicle has 10 recall campaigns on file. An open recall needs VIN-specific confirmation. Many are quick, no-charge fixes and worth negotiating over; an unresolved do-not-drive advisory, or a remedy the manufacturer has not yet made available, should stop the purchase until it is resolved.
- Ask the dealer whether the warranty extension on file still applies to this VIN.The manufacturer issued 1 warranty extension for this vehicle (see the service bulletins section). Extended coverage often runs by years or miles from the original sale, and a repair the seller paid for may have been free.
- Ask for the service history in writing, then read it against this page.The complaint families above are where owners of this vehicle report trouble. Repairs in exactly those systems are evidence the car had the problem; no such repairs could mean it never developed it, or that it was never fixed. The test-drive items above are how you tell those apart.
Parts search directory
The generic parts list for this vehicle has its own page: a search launcher for every system, filtered by fuel type and era but not by engine, trim, or brake type. It is not a diagnosis and not a fitment guarantee.
