John it may be helpful to mention that, if it listed is on the DVSA website it will be a reportable safety problem that relates to a required corrective action to protect the safety of the public. This has to be backed up by the OEM taking clear steps to contact owners from a defined VIN range and "recalling" the car to a dealer for an FOC inspection and repair. The most recent owner details in this situation are supplied by DVLA and the OEM should monitor correction rates to define if further follow up contact with owners is needed. Running alongside this, most OEM's will take "policy" decisions on, what they view as non safety critical issues, but where they see unreasonable risk to predicted reliability or durability of a vehicle. With this there is no DVSA reporting, and they will not contact owners to recall cars. However the OEM will notify dealers of VIN details of cars to be checked and modified during "next visit to the workshop". These next visit tweaks are usually, but not always 100% FOC, with the dealer submitting his bill to the OEM.
