How recall repairs work

  • Repairs are free at any franchised Mazda dealer — regardless of the vehicle's age or whether you bought it new.
  • Bring the NHTSA campaign number; it's printed on each recall above and on the sheet you can print here.
  • Call ahead: some recalls are announced before parts are available, and the dealer can tell you when yours are in.
  • Your VIN tells the dealer whether your exact vehicle is affected — the free check accepts one and never stores it.
