GM Recalling 33,700 Vehicles Over Software Issue
GM said the problem may cause the transmission to unexpectedly slip from manual to automatic mode. The U.S. automaker said there are no reports of crashes or injuries related to the issue.
Dealers will reprogram the transmission control module free of charge.
The Detroit company also recalled 48 compressed natural gas-powered versions of the 2011-model Chevrolet Express full-sized vans to repair a potentially incorrectly built pressure relief vent pipe that could allow natural gas into the passenger compartment and increase the risk of an explosion or fire.
GM said all the vans, which were sold to three U.S. fleet customers and one dealer, have been inspected, and there were no reported crashes, injuries or fires related to the issue.
