Known Problems

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

The fuel pump may fail causing the engine to stall and not restart.

On some models the hood release cable breaks at the hood release handle.

The remote keyless entry system may not work intermittently. Our technicians suggest upgrading the software in the wireless ignition node (WIN) to correct this concern.

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

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.

An abnormal noise from the timing chain area is likely due to a failed timing chain tensioner. This condition is generally caused by lack of oil to the timing chain guides and the guides will need replacement. 

The check engine light can illuminate and set a P0008 trouble code when this issue occurs. This is due to the Camshaft and Crankshaft Sensors detecting that the engine timing is out of specification. 

The power steering pump and power steering hoses tend to develop leaks, particularly in the V6 models.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

Owners have reported a number of prematurely worn front wheel bearings. As the bearing fails, a rotational humming or grinding noise may be noted from the front as vehicle speed increases. Replacement of the bearing would be necessary to remedy this condition.

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.

The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.

The cup holder in the center console may break.

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 automatic transmission shifter may fail, or a wire may break near the shifter causing the ignition key to become stuck in the ignition lock cylinder.

An engine misfire at idle (rough idle), accompanied by illumination or flashing of the Check Engine Light, could indicate a problem with one or more of the intake valves. Revised intake valves & valve locks are available to address this concern.

One or more of the power window regulators (one in each door) may fail causing the window to fall into the door and not roll up.

Sometimes the Check Engine Light illuminates because the computer detects misfires. Subaru released an improved spark plug wire set to solve the problem. The ignition coil should also be inspected for carbon tracks or short circuits between the contacts

The common problem for ignition misfires are ignition coils going bad. Replacement of the bad ignition coil is necessary. These should be fixed as soon as a problem is detected. Otherwise the misfire can cause damage to other components.

There have been numerous complaints of early transmission failure, even with with normal servicing. Issues start with a whining noise, overheat warnings, and an inability to accelerate. The most common solution is replacement of the transmission. Late 2014 model year Patriots changed to a non-CVT transmission.

The accelerator position switch may fail intermittently resulting in sluggish acceleration or lack of power.

The evaporative emission (EVAP) system may illuminate the vehicle's Check Engine Light due to intermittent failure of the charcoal canister purge control solenoid valve or canister failure. Upon failure of the charcoal canister, debris may circulate around the EVAP system causing other emission control problems.

On some models a void in the rear window seal may cause a water leak. Water may be present on or under the carpet. The seal will need to be replaced if that is the source.

If you experience rough shift and/or shuddering during gear shifting, software updates to the powertrain control and transmission control modules (PCM and TCM) are available which may address these problems. On higher mileage vehicles, a mechanical failure may exhibit similar symptoms. Proper diagnoses should be performed before any repairs or software upgrades are attempted.
