Known Problems

On the 2.7L V6 and 2.4L 4 Cylinder, a defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

If the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.

    Parking lights not turning off intermittently or all the time. The common problem is with the cabin fuse box.  Complete replacement of the assembly is necessary to fix the problem.

Problems with the accelerator pedal position switch may cause the Check Engine Light to illuminate; an improved switch is available to fix this problem.

Concerned about safety, the NHTSA is investigating reports of rust forming at the front suspension mounting points, the frame, and the sub-frame. Some of these vehicles may have been recalled for this issue. For more information, please click here»

The timing belt can fail prematurely; if it fails while driving, it can cause catastrophic damage to the engine. Be sure that the timing belt is inspected and replaced according to the manufacturer's recommended schedule.

Premature timing belt failure may result in serious engine damage. When replacing a broken timing belt, it is important to inspect and possibly replace the crankshaft position sensor; it is often damaged when the timing belt breaks.
