Known Problems

Occasionally, the anti-lock brake (ABS) warning light may illuminate. This could be due to a faulty rear wheel speed sensor. The sensor design has been updated and revised parts are available to correct this problem.

 

The driver's door latch assembly can break internally, which causes the door to stay closed. The interior and exterior door handles do not work to open the door. Our technicians note that the door panel must be removed while the door is closed (likely damage will occur) and the latch assembly must be drilled in a specific spot for the door to open.

A long cranking time before the engine starts might require a PCM software update and replacement of the fuel pressure regulator.
The car may drift to the right because the camber (alignment setting) is set unevenly. A 4-wheel alignment will be needed to reset the camber angle.

If the brake pedal feels hard the first time it is pressed in the morning, it could be due to a problem with the vacuum supply hose for the brake booster. A revised brake booster hose is available to address this concern.

One or both of the rear sway bar end links may break resulting in a knocking noise from the rear of the vehicle.

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

The computer can misinterpret a low battery voltage and can cause a false Check Engine (MIL) light to come on. Updating the PCM can correct this issue.

If the engine is knocking or pinging when accelerating, the PCM may need updated software.

The PCM can misinterpret data from the air fuel sensor and set a false Check Engine (MIL) light requiring a PCM update to repair.

Plugged moon roof drains can cause a water leak inside the car. The water will usually leak onto the driver's or passenger's head when the car turns a corner.

A faulty Electric Load Detector (ELD) can cause the head lights to dim and/or illuminate the Check Engine Light. A failed ELD will require replacement.
