NHTSA recalls: verify this VIN
A recall that applies to a model is not proof that a specific car has an open recall. Whether this VIN is affected, and whether the repair was done, is shown by NHTSA's VIN lookup. Check it before you bid.
No campaign list is stored for this generation. Look the VIN up with NHTSA.
Check this VIN’s recall status at nhtsa.gov/recalls →Manufacturer bulletins (TSBs)
Technical service bulletins are the manufacturer's own guidance to its dealers. A bulletin is not a recall and does not mean a repair is free. Coverage depends on the manufacturer's terms and the VIN.
