On higher mileage vehicles timing cover oil and coolant leaks, front crankshaft oil seal leaks, and valve cover gasket leaks are common. Our technicians recommend replacing the timing chain and gears if the timing cover is removed for resealing. It is also recommended to inspect the oil pan gasket and replace the drive belts and tensioners at this time.
A high pitched whistle type noise may be noted from the engine at idle. The repair for this condition can include replacing the idle air control motor with an updated part.
A hard or no start condition may be noted in low ambient temperatures which can be caused by corrosion at the engine coolant temperature sensor. If this is the case the coolant sensor and its pigtail should be replaced with updated parts.
A rattle may be noted from the rear brakes when driving on rough roads. If the rattle is eliminated with light brake application replacing the rear brake pads with a revised part may correct this concern.
Automatic transmissions can exhibit a variety of shifting and noise concerns due to failure of internal components. Our technicians tell us that due to the fact numerous updated parts are available for this transmission a complete inspection of all internal parts should be performed if the transmission is disassembled for overhaul.
The connector on the input and/or output speed sensors on the automatic transmission may become damaged causing intermittent loss of speed control. Our technicians tell us there are wiring repair kits available to repair this issue.
A faulty transaxle input speed sensor can cause the automatic transmission to default into a "limp-in" mode. Our technicians tell us there is an updated input speed sensor available to correct this condition.
Carbon buildup on the top of the piston is common. Over time this can lead to symptoms varying from light ticking to knocking noises. Performing a fuel injector cleaning procedure can often help the condition by removing some of the piston top deposits.
A slight engine knocking noise may be noted on light acceleration after a cold start. Our technicians tell us there is powertrain control module (PCM) software update available which may correct this issue.
The brake lights may stay on and the cruise control may not function due to the brake pedal not returning to its fully released position. Our technicians tell us that if a complete inspection of the brake system reveals no fault there is a brake pedal return spring kit to correct this issue.
