Defect
On certain vehicles, the tire pressure monitoring system (TPMS) warning light may not turn on when the tire pressure is low. Driving a vehicle with low tire pressure could lead to poor handling and/or a tire failure.
Safety Risk
Poor handling or a tire failure could cause a loss of control and increase the risk of a crash.
Remedy
To reduce the safety risk, Aston Martin recommends that you should check the tire pressure and ensure that it matches the pressures listed on the tire and loading information label located inside the driver's door jamb. Aston Martin will notify owners by mail and advise you to take your vehicle to a dealership to update the TPMS software.
