Known Problems

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).

Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.

Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

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.

The sky slider sunroof may not open. A software upgrade for the control module is available which should correct this concern.

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.

Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Low fluid level in the differential or transfer case can result in bearing failure. Damaged bearings commonly cause a whine or growl type noise.

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 service 4WD system light may illuminate with no fault codes stored in the final drive control module (FDCM). Our technicians tell us a software update for the FDCM is available to correct this concern.

The door molding may become loose on one or both front doors. Our technicians recommend to replace the molding if this occurs.

The power window motor commonly fails in the front and rear doors. This may require replacement of the complete window regulator assembly which will include the window motor.
