GM Recalling Colorado and Canyon Trucks
July, 2011General Motors will replace a defective shift cable clip in about 9,000 Colorado and Canyon trucks equipped with automatic transmissions. The current clip may allow the cable to move out of position. If that happens, placing the shift lever into "Park" will appear to be successful, but won't actually put the transmission into park mode. The problem may not be immediately noticeable, because a driver could still turn off the ignition and remove the key, usually a signal that system components are where they should be.
But the truck can still roll, because "Park" hasn't truly been achieved.
Colorado and Canyon truck owners should start receiving notices in mid to late July, 2011.
