ASTON MARTIN DB9, DBS, VIRAGE, RAPIDE & VANQUISH (2008–2016)
What the hazard is
If the vehicle accidentally moves from the parked position it may pose a risk of injury to the driver or other persons and possible damage to property.
What to do
Owners will be notified by direct mail. Owners will be advised to contact their nearest Aston Martin Dealer to arrange an inspection of the vehicle. The software update for the Transmission Control Module (TCM) will be completed at no cost to the owner.
Defect
A communication error between the Engine Control Module (ECM) software and the Transmission Control Module (TCM) can cause the transmission park pawl to be held out. When the transmission park pawl is held out, this can let the vehicle roll away from its parked position. This problem can occur when all of the following conditions are met: a) the vehicle key is removed from the ignition control and the engine speed is more than 450 rpm; b) the driver does not select Park; c) the driver does not engage the park brake; d) the vehicle is not parked on level ground; and e) there is a communication error between the ECM and the TCM.
