On a 2002 Chevrolet Impala, the security light comes on while driving. Following this event various electrical abnormalities occur. Dashboard warning lights all flash together, dash goes dark. Sometimes when you start the car the security light comes on and the headlights flash as if they were icc flashers. There are numerous complaints about this on the internet. Chevrolet doesn't seem to have any finite fix for this and randomly replaces the BCM and ignition switch as possible causes. Most people report having the exact same problem over again several days later"?" due to this erroneous reporting I thought I had a battery problem and the garage changed my alternator. At a cost of $306 dollars. Which I now believe was totally un-necessary.

Starting 2/05 I have had the "security" warning light and my engine fail to start on 3 separate occasions. I had to replace the BCM the first time but have now been told that there is a tsb on this issue and that, per GM, I need to replace the ignition switch and associated parts to prevent my vehicle from shutting down on the road. If that is not a safety hazard I don't know what is. GM knows about this but will not stand behind it's defect until a major accident happens. They should do a recall and have these all repaired before a major accident does take place. They should be held accountable before a life is lost because of a well known documented flaw.

Problem with message center, security lite comes on then battery lite, then service vehicle soon, then air conditioning would not turn on, started funny, did not start turning over when I first turned the key it started to turn over about 1 sec after turning the key and started ok then. All of this happened a the same time for the first time. Prior to this I reported a popping/snapping noise when you turned the key. The chev dealer said this was normal (3 weeks prior to the problem).
