General Motors announced a recall Friday of more than 400,000 sedans in the U.S. because of a transmission problem that causes cars to roll when they're supposed to be in park.
GM said the recall applies to 426,240 Chevrolet, Pontiac and Saturn sedans to repair a condition in which the transmission gear position may not match the gear on the shifter. If left unfixed, GM says drivers may think they're still in park, but their vehicles are rolling.
The company said this is a potential problem in certain cars with four-speed automatic transmissions built from 2007 to 2010, including Chevrolet Malibus, Saturn Aura and Pontiac G6 models.
Additionally, nearly 50,000 of the same models are being recalled in Canada, Mexico and other countries.
The transmission problem has results in four crashes, but no injuries, according to GM.
Owners of the cars are being asked to bring them to GM dealerships, where mechanics will reinforce the shift cable end fitting to prevent it from fracturing.
Earlier this summer, GM recalled more than 400,000 Chevrolet Cruzes for engine trouble.
