BEFORE YOU BUY

What to check on this car

Confirm the recalls were fixed

This model has 2 open NHTSA recalls (including the forward collision avoidance). Recall repairs are free at the dealer, so ask the seller for proof the remedy was performed, or verify by VIN at nhtsa.gov before you buy.

Have a mechanic check the forward collision avoidance

Owners report problems with the forward collision avoidance more than anything else on this model. Call it out specifically during a pre-purchase inspection.

Watch for a pending investigation

NHTSA has an open investigation covering this model. A recall can follow an investigation, so check nhtsa.gov for the latest before you commit.

  • Test-drive the basics

    Cold start, full-lock steering both ways, firm brakes with no pulsing, smooth shifts, and every electronic feature. Warning lights should come on at key-on, then go out.

  • Check the title and the VIN

    Confirm the title status in hand matches the listing, and that the VIN matches across the dash, door jamb, and title. VINly does not show ownership or accident history, for that, run a paid report like Carfax.

  • Ask the seller the right questions

    Why they are selling, any service records, accident or panel-repaint history, how many owners, and whether any open recalls were completed.

See the full used-car inspection checklist. None of this replaces a hands-on inspection by a mechanic.
