XC60 and XC70 vehicles because of unexpected engine stalling.According to the National Highway Traffic Safety Administration, Volvo is calling back 6,046 2011 S60, S80,
"The software calibration for the fuel cutoff functionality in the engine control module is too sensitive," said NHTSA. "Sudden engine stall could occur, increasing the risk of a crash."
Volvo clarified that the problem arises when the driver is braking "during city driving and/or releases the accelerator pedal."
"The engine idle speed may drop, resulting in a sudden engine stall without any prior warning," it said. "If this condition occurs, the transmission control unit will enter a temporary protection mode in order to prevent damage to the vehicle's transmission. When starting the vehicle again, the driver can operate the vehicle safely home or to an authorised Volvo repair facility, but may experience a louder than usual transmission and a harder gear engagement."
The recall is expected to begin on 10th December.
