BEFORE YOU BUY
What to check on this car
Confirm the recalls were fixed
This model has 3 open NHTSA recalls (including the tires). 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 electrical system
Owners report problems with the electrical system 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.
