Known Problems

An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. To help prevent this issue from occurring, the cam follower should be inspected every 10,000 - 15,000 miles. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. 

To correct this issue one or all of the following will need replacement: the camshaft, high-pressure fuel pump, and/or the cam follower.


One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.

Reverse gear failures and noise in the manual transmission models are common.

Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.

The water pump and/or other cooling system may develop a coolant leak. Oil leaking from the  valve cover gasket is also common.

A damaged water pump impeller may cause an engine overheating condition. Our technicians tell us the repair should include replacement of the water pump, thermostat, and flushing the cooling system.

Throttle body failure is not uncommon and can lead to shifting issues with the automatic transmission and other drivability concerns.

Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.

Due to an ignition component and/or engine coolant temperature sensor failure, the Check Engine Light may illuminate. Replacement of the failed component will be necessary to correct this concern.

Condensation in the heater case may cause a musty odor from the heating, ventilation and AC (HVAC) system after sitting for two hours or more. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.

Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.
