WASHINGTON - Volvo Cars of N.A. is recalling more than 6,000 MY 2011 S60, S80, XC60 and XC70 vehicles because of a potential stalling problem. 

According to the National Highway Traffic Safety Administration, the software calibration for the fuel cut-off functionality in the engine control module is too sensitive. A sudden engine stall could occur, increasing the risk of a crash. 

To remedy the problem, Volvo dealers will update the ECM and TCM with new software free of charge. 

Vehicle owners can reach Volvo at (800) 458-1552.
