What the owner should do?

If you read about a recall that you think may affect 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.

If you wish to know more about eventual problems of a specific car (e.g. real mileage, potential traffic accidents damages, odometer rollback, repairs, etc.), then we suggest going to HPI-Check.
