Is my car affected?
Being on this list means your year, make and model fall inside campaign 24V839000. It does not mean your individual car does: a campaign covers a range of VINs built in a specific window, and cars either side of that window are untouched.
Check the 17-character VIN from the driver-side dashboard or door jamb against NHTSA's lookup. If it is covered, the dealer must do the work free of charge, regardless of the car's age or mileage.
