According to the automaker, the vehicles with the faulty oil pressure gauge may not alert the driver of a low oil pressure situation. Without being warned of a low oil pressure situation, the driver may continue to drive the vehicle until it stalls, increasing the risk of a crash.
Volvo is in the process of notifying owners of the affected vehicles. The solution requires a Volvo dealer to update the vehicle's software so that the oil pressure gauge functions normally. Dealers will provide this service free of charge to S60 owners affected by the recall.
