Specifications show one example EPA configuration for this model year; other engines, drivetrains, and trims exist and the records below cover all of them.
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.

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.

  1. Drive one straight highway stretch and one slow parking lot.Wander or a shimmy over bumps at speed, and heavy or dropped assist at low speed, are the two faces of this vehicle's steering cluster. A clunk on turn-in points at the linkage.
  2. Watch the airbag warning light through a full key cycle.It should light on start and go out within seconds. A light that stays on, or never lights at all, means the system needs attention. Run the VIN for inflator recalls specifically.
  3. 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.
  4. Run the VIN against open recalls before you negotiate.This vehicle has 4 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.
  5. 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.
