Known Problems

The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

The AC system may not blow cold at times. In many cases, replacement of the AC compressor has corrected this issue.

An engine oil leak may develop from the front crankshaft seal. Our technicians tell us a revised front crankshaft seal is available to correct this concern.

Water leaks may be noted from the front and/or rear roof area. Our technicians recommend to inspect the roof ditch and sunroof - Check all grommets and plugs, reseal roof seams, and replace the sunroof drain tubes if necessary.

The check engine light may come on due to failure of the Variable Camshaft Timing (VCT) solenoids. The VCT solenoids will need to be replaced if they are the reason the check engine light came on.

The automatic transmission may fail prematurely. Transmission overhaul or replacement may be necessary to correct this concern.

The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

The AC evaporator can develop a refrigerant leak. The AC system will not blow cold air if this happens.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

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 front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn too thin, replaced to correct this issue.

The front or rear differential may develop an abnormal noise due to worn bearings or another internal fault. Our technicians tell us that a complete overhaul of the affected differential is commonly necessary to correct this condition.

The power door lock actuators may become slow to operate or stop working completely and require replacement.

Difficulty starting the vehicle may be caused by a defective vehicle immobilizer (anti-theft) control module.

If the engine is excessively noisy on startup (after the engine has been off for several hours) and the noise lasts more than four or five seconds, turn off the engine and check for correct engine oil level. If the oil level is correct, the noise may be caused by the timing chain tensioner. Kia released an updated timing chain tensioner to solve this problem.

The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.

There are reports of premature clutch wear on cars equipped with manual transmissions.  Clutch replacement on these vehicles can be quite costly.

Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. The affected door latch should be replaced to correct this concern.

The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.

The head gasket has a high failure rate due to cooling system problems. Subaru is aware of the problem and has extended the warranty to 8 years/100k miles on many vehicles.

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.


Damaged engine mounts can lead to vibration and roughness felt in the steering wheel. A rattle in the dash and engine area may also be heard. Replacement of damaged mounts will commonly correct these issues.

Vehicles may develop a start and die out condition or a transmission that defaults to second gear. Our technicians tell us that the transmission control module (TCM) may be at fault and require replacement. Our technicians tell us that if the TCM is replaced the pinion factor should be reset and the quick learn procedure performed.

The steering wheel position sensor may fail, resulting in the service stability message being displayed.

Various electrical issues may develop related to the body control module (BCM). There have been reports of water damage to the BCM caused by clogged or damaged sunroof drains. It is recommend to periodically inspect the sun roof drain for debris and clean as necessary.
