Certain vehicles equipped with Active Body Control (ABC) the sensors on the front struts may not operate within tolerances. As such, the sensor signal may not be accurately transmitted to the Electronic Control Unit (ECU). A variation in the transmitted values can result in one front strut adjusting to a value while the other does not adjust and presenting the driver with an uneven front suspension. This situation could have an effect on the vehicle's directional stability, possibly resulting in a vehicle crash with injuries or death. Correction: Dealers will inspect and replace affected AZ-sensors

On certain vehicles equipped with an 8-cylinder engine, corrosion may occur in the inner steel portions of the Active Body Control's high pressure distribution hose due to extensive exposure to humidity. This may result in ABC hydraulic fluid leakage near the catalictic converter which could cause a fire. Correction: Dealers will install a corrosion resistant ABC high-pressure distribution hose.

Certain vehicles may experience instrument cluster backlighting malfunction. There are three distinct failure modes. (1) Vehicles built between 06/2000 and 11/2000 may contain a defective transformer that could cause an electrical short. (2) Vehicles built from 01/2002 to 04/2002 could have incorrect dielectric layers inside a capacitor that could lead to fluctuating current levels. (3) Vehicles built between 05/2004 and 09/2004 may have incorrect light emitting diodes (LEDs). Correction: Dealers will replace the instrument cluster module.
