2021 Audi S6 Review

Checking if a car has a recall is simple. Just type the car's VIN number into the NHTSA website (https://www.nhtsa.gov/recalls). If there's an unrepaired recall, you'll see it there.

If a recall shows up, just call your local car dealer. They'll know about the recall and will work with the car maker to fix it for free (if the recall happened within 10 years of the car being first sold).
