The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
The steering may develop a clunk type noise from the upper intermediate steering shaft. Our technicians tell us that you should check with your local GM dealer to find out what the latest repair is for this condition.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
Flex fuel vehicles can develop fuel calibration issues resulting in illumination of the Check Engine Light and/or lack of power. This commonly occurs if only short trips are taken after changing fuel type from E85 to gasoline or gasoline to E85. In most cases, the fuel calibrations can be reset for gasoline using a properly equipped scan tool.
The engine light was on and the car seemed to be running fine. That is when i went in to hook it up to the diagnostic machine. We found out it was the oil pressure sensor. You do have to order the part through GM, but it is only $10.00. my husband fixed it in about 10 min.
my car will stall for a couple of days before my service traction control message comes up and right after then my engine power is reduced message comes up i took my car to a shop they said my trottle body needed to be cleaned but it is still doing the same thing.
Wires broke on side of shifter. This part will fix it. GM #13583923 or acdelco #pt3923 around 20 bucks. It has 6 wires on it but all you have to do is cut 2 wires off that you dont need. It took me about an hour to fix this.
