Volvo Cars of North America is recall a small number of 2011-13 model year S80 sedans, said the National Highway Traffic Safety Administration (NHTSA). According to the safety agency, certain models of the sedans with automatic transmissions may be unable to downshift from higher gears, possibly resulting in an unexpected engine stall and thereby increasing the risk of a collision.

NHTSA says the problem is due to a transmission software error in the Volvo S80. While this current recall affects less than 1,500 Volvo sedans, the 2012 model of Volvo S80s were also recalled for wiring issues earlier this year.

Volvo wil notify owners affected by this latest automatic transmission safety issue and request that they bring their recalled S80 vehicles to local dealerships. Mechanics there will update the S80's transmission control module free of charge.

For more information, consumers may call Volvo's toll-free customer support line (800-458-1552) and reference Volvo's internal recall campaign number: 255.
