The steering rack may fail causing a loss of power steering fluid as a result the steering may become hard to turn.
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.

Door would not automatically unlock from the remote or when the master lock switch was opened and the window would not work.
Left Rear Door Module (Part #: 25654368) was bad -- Symptom: door would not automatically unlock and the window would not work.
troubleshooting: pried off the plastic cover behind the door handle (start at the hinge side), removed single screw and then starting at the bottom pulled off the door covering (It is held in with plastic snaps), found 12v going into the door module and deduced the module was the problem; found one on ebay motors ...
The cam sensor interrupter (magnet) may become demagnetized and/or fall off of the camshaft gear causing the Check Engine Light (Service Engine Soon) light to illuminate. On higher mileage vehicles it would be advisable to replace the timing chain and gears if this problem were to occur as the timing cover must be removed to replace the interrupter.
The upper intake manifold may develop an internal coolant leak causing one or more cylinders to fill with coolant. This can cause the engine to "hydro-lock" and not turn over. Removing the spark plugs will allow the engine to turn over pushing the coolant out of the spark plug holes. Replacing the upper intake plenum and gasket is commonly required to correct this condition.
The engine can be very difficult to start after this problem has been repaired, it can be helpful to clear as much of the coolant from the intake manifold and cylinders as possible before reassembling the intake manifold.
