General Motors has issued a recall for certain 2011 Chevrolet Colorado and 2011 GMC Canyon trucks with 2.9 or 3.7 liter engines and four speed automatic transmissions. According to the recall, the trucks may have been built with an automatic transmission adjustment clip that may not keep the shift cable in the correct position. The shift lever may not show the correct position of the transmission gear resulting in drivers thinking the vehicle is in park when it is not. This condition could result in the vehicle unexpectedly rolling away or the driver may not be able to start the engine. Owners wanting more information on the recall can contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
