2012 Jeep Wrangler Problems

Water May Leak From A-pillar on Side Doors

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

Throttle Position Sensor May Fail

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.

Updated Pressure Cycling Switch Available to Fix Frozen AC Evaporator

The AC evaporator may freeze after extended use of the air conditioner. The output may feel low due to the restricted evaporator. Once the ice buildup melts, the AC operates normally. A revised low pressure cycling switch is available which may fix this concern.

2012 Jeep Wrangler Recalls

Exterior Heated Mirror Failure

The heated outside rear view mirrors may develop corrosion in the wiring connectors that supply power to them. This can cause a fire hazard. Dealers will modify these wire connectors to provide a separate power feed free of charge to resolve this concern.

Potential Transmission Fluid Leak

The power steering system and automatic transmission each have associated fluid lines. 2012 & 2013 Wrangler models equipped with both of these options are being recalled because a power steering fluid line can rub on one of the transmission oil cooler lines and wear a hole in the transmission line, causing a leak. Loss of transmission fluid can result in failure of the transmission to operate, increasing the risk of a crash. Dealers will replace the power steering return tube assembly to correct this concern.

 

The Driver's Front Air Bag may not Deploy as Expected

The clockspring is a coil of wire located behind the steering wheel, it allows the steering wheel to turn and still maintain the electrical connection between the steering column and the rotating steering wheel. Certain right hand drive models are being recalled because the circuit inside the clockspring could break. This could result in illumination of the airbag warning light and/or no-deployment of the driver's front airbag in the event of a crash. Dealers will replace the clockspring and add a steering wheel dust shield to correct this concern.
