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 anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
Problems with the anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The the key and ignition lock cylinder must be replaced to correct this condition.
The outer tie rod ends on the steering linkage may wear causing excessive free play in the steering and uneven tire wear. If the worn tie rod ends are replaced, the wheel alignment should be checked and adjusted as necessary.
The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
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.
