DETROIT (WWJ/AP) – General Motors is recalling nearly 27,000 Buicks and Cadillacs in the U.S. to fix a problem with the automatic transmissions.

The recall affects Buick LaCrosse full-size cars and Cadillac SRX crossover SUVs from the 2013 model year.

The Buicks were built from April 25, 2012 through March 6, 2013. The Cadillacs were built from May 29, 2012 through Feb. 18, 2013.

The company says a software problem can cause the transmissions to inadvertently shift into sport mode. That can unexpectedly override any slowing effect from the transmission, increasing the risk of a crash.

GM says no crashes or injuries have been reported.

GM will begin notifying owners later this month, and dealers will reprogram the transmission control module free of charge.

For more information, Cadillac owners can call 1-866-982-2339, and Buick owners can call 1-866-694-6546.
