General Motors is recalling 26,582 model year 2013 Cadillac SRX crossovers and Buick LaCrosse sedans to fix a software problem that could allow the vehicles' transmissions to slip suddenly from manual to automatic mode.
Information posted on the National Highway Traffic Safety Administration website said that the software problem may cause the transmissions to inadvertently shift to sport mode, removing any transmission-related engine braking effect.
The NHTSA said that the risks of a crash are increased if engine braking is unexpectedly removed.
GM said in a statement that the issue was discovered on a 2014 engineering development vehicle.
The company hasn't received any complaints about the problem, it said, adding that it has no reports of crashes or injuries related to the problem.
GM said dealers will reprogram the transmission control module for free.
The LaCrosses were manufactured between April 25, 2012, through March 6. The Cadillac SRXs were built from May 29, 2012, through Feb. 18.
In a separate matter, NHTSA also posted a safety recall for 48 model year 2011 compressed natural gas versions of the Chevrolet Express full-size van.
The recall was issued because an improperly built pressure release vent pipe could allow natural gas to vent into the passenger compartment, increasing the risks of an explosion or fire.
