7,558 of Volvo Motors’ model year 2012 S60 sedans made between November 18, 2010 and May 5, 2011. The fuel pump software of these Volvo S60s may not be able to read certain pumps or components accurately, which could lead to an improper amount of fuel transfer to the pump unit. This could cause hesitation and/or stalling due to lack of fuel even if the fuel gauge reads as having a sufficient amount of gasoline in the engine. This can be very dangerous during certain driving conditions. To contact the National Highway Traffic Safety Administration, call (888) 327-4236.
