Model Years Affected: 2000, 2001, 2002, 2003, 2004, 2005

Engines Affected: 3.4L V6, 3.8L V6

Average Mileage: 117,921 mi (35,000 mi - 236,772 mi)

Verified

The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.

    NOT STARTING and SECURITY LIGHT is problem--no problem with engine stalling
    every month or so--SECURITY LIGHT comes on and stayed on for few minutes
    6 months ago, 3 months ago
    when key turned to start car--no sound--not start
    all electrical devices work
    wait---then start after 3 to 15 minutes--engine has NEVER stalled
    then last week, not start, rotate through messages
    3 minutes, 15 minutes later--still not start
    half hour later, car started, but CHECK ENGINE LIGHT came on and stayed continuously each time engine was started
    Mechanic charged retail to replace ignition lock cylinder $ 225.90, almost that much to remove and replace, plus diagnostic fee, and recoding and reprogramming fee
