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.
The intake manifold gasket can develop external engine oil or coolant leaks. In some cases the failed gasket will leak coolant internally. The manifold gasket will need to be replaced to correct this issue.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
if my car is parked on a hill and i have to put it in reverse it does a really hard jolt or a kick. while im driving it does it again around 30 mph and again around 60 mph. sometimes if im at a stop light it kind of jerks as i start to take off.
The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.
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.
