What the owner should do?

You can check if your specific car is affected by a recall by entering your Vehicle Identification Number (VIN) on the NHTSA website. The VIN is a unique code that identifies your vehicle and can be found on your car's registration, insurance documents, or near the base of the windshield on the driver's side.

Check recalls by VIN

If the recall involves your car, you should make immediate contact with a dealer or workshop that’s been officially authorised to perform repairs on behalf of the manufacturer and ask for the details.
