2011 Cruze 107,000 KM same issue as the rest of you, Stabilitrak, clock resets to 24hr time, Limp mode, the only other difference is I put on winter tires and have a tire senor monitor alarm that re -flashes. Does this neg. ground bolts fix work? I have replaced the battery, asked GM tech to have all the connections re-tightend on the battery cables. They replaced the Throttle Position Sensor because of Code P2135. With a $400.00 bill, Still not fixed? This is a common problem that GM fails to recognize as a defect. Back to the dealer in the morning they're at a loss, any help from anybody? I can't even trade this thing off on a new dart because of this issue!!
