One problem related to anti-theft controller has been reported for the 2009 GMC Canyon.
Anti-theft system would not allow the truck to start, then once started the entire dashboard components failed no speedometer, fuel, temp or air conditioner would work, also the traction control went into alarm. . . GMC people said they could not see any alarm codes and failed to repair the anti-theft system. . . Recommended I get on-star to help identify the problem. . I did, it failed again and on-star saw the codes however GMC says they cannot trust on-star findings, even though they recommended them which is costing me $30. 00 a month to monitor their vehicles warranty. . Still driving a truck that sometimes does not start and the entire dashboard shuts down while driving. . . Very dangerous.
