Known Problems

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

A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.

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.

Loose or worn suspension and steering components can cause a wobble or shaking in the steering wheel. It may happen at a certain speed and subside as the vehicle accelerates through the range. Tire balance can contribute to this as well.

If water leaks into the passenger compartment and under the passenger side carpet, an heating, ventilation and AC (HVAC) drain hose is available.

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.
