WASHINGTON — General Motors is recalling 26,582 2013 Buick LaCrosse and Cadillac SRX vehicles because a software problem may lead to a loss of engine braking, according to the National Highway Traffic Safety Administration.

"A software problem may cause the transmission to inadvertently shift to Sport mode, removing any transmission-related engine braking effect," said NHTSA in its summary of the reason for the recall. "If engine braking is unexpectedly removed, it may increase the risk of a vehicle crash."

There are no reported customer cases nor are there any known crashes or injuries related to the condition, said GM in a statement on Wednesday. The company said the defect could allow the vehicles to slip from manual to automatic mode unexpectedly.

The affected vehicles were manufactured from April 25, 2012 through March 6, 2013.

GM told federal safety regulators that the problem was discovered on January 9 on a 2014 Cadillac SRX engineering development vehicle. On February 23, the issue was confirmed to exist on "certain high-content level 2013 LaCrosse vehicles," GM said.

"These vehicles are equipped with the Driver Shift Control (DSC) feature, commonly called Manual Mode, that allows the driver to shift the automatic transmission similar to a manual transmission," said GM in documentation filed with NHTSA. "The transmission software in these vehicles may cause the transmission to shift from DSC (manual) mode to Sport mode (automatic shifting) unexpectedly. If the driver had used the DSC (manual) mode to achieve engine braking, engine braking would be cancelled.

"DSC mode can be re-engaged by moving the shift lever to Drive and then back to the DSC mode."

GM dealers will reprogram the transmission control module. The recall is expected to begin on March 28. Owners can contact Cadillac at 1-866-982-2339 or Buick at 1-866-694-6546.

Edmunds says: If you own one of the aforementioned 2013 Buick LaCrosse or Cadillac SRX vehicles, it should be a fairly quick fix next week.
