Recall 04V060000: Steering Column Lock Defect

DEFECT: On certain passenger vehicles equipped with electronic column lock systems (ECL), when the ignition switch is turned to "lock," the ECL prevents turning of the steering wheel. When the vehicle is started, the ECL unlocks the steering column. The vehicle is designed so that if the column fails to unlock when the vehicle is started and the customer tries to drive away, the fuel supply will be shut off stopping the engine. This prevents the vehicle from being driven when it cannot be steered. However, if voltage at the Powertrain Control Module is low or interrupted, the fuel shut off may not occur and the vehicle can be driven while the steering column is locked. If this occurs, a crash could occur.


REMEDY: On vehicles equipped with an automatic transmission, the dealer will disable the steering column lock by removing the column lock plate. When the ignition key is removed, the transmission shifter will lock, but the steering column will not lock. On vehicles equipped with a manual transmission, the dealer will reprogram the powertrain control module. The steering column on these vehicles will continue to lock when the key is removed. The manufacturer has reported that owner notification is expected to begin during the second quarter of 2004. Owners may contact Chevrolet at 1-800-630-2438.
