Couple of weeks ago the wife tells me her lights suddenly shut off on their own on her way to work, then popped back on about
2mins later. So I trade cars with her, drive it for a week and nothing happens to me. Trade back to my old truck and life is
good again- I just figgered it was operator error.

Well, 2 days ago she said... "The lights are ok, but now the security light popped on and the battery light is also, and it says check engine what do I do." Well, as we were talking the lights went back off. I again swapped cars with her. I called on-star,
they ran a check and said they found nothing. I was driving today
and was considering swapping back to my old truck when it finally
happened to me.
Security light/battery light on, a chime signal and a check engine light, and again after a few mins they went back off.
Luckily I was close to home so I just took it home.
Being though all the Chev dealers are closed I did some research
on 2002 Chev electrical problems and came up with hundreds of reports. Same thing, some cars as new as 20thou miles, some well
over 100k. All the same repair-

1. Change the key lock assembly $200.00-$350.00 depending
on car. and if that doesnt fix it-
2. Change the BCM at $400.00-$800.00.

Can You Chev guys tell me if GM is doing anything to help the
owner offset what appears to be a very expensive defect.
Oh, I forgot to mention- the fix is perhaps only temporary
as GM is replacing the defective parts with the same poorly
designed parts that have a known failure rate.
Can you shed any light on this subject??

Thanks for you time...

Sorry that it happened to your wifes car. See a few that had a problem with the Lock and Cylinder assy, if it's not under warranty you may just have to cover the cost. Sucks!

Check your battery connections to make sure you dont have any acid leaking out of the positive post.

Thanks for the replies...
It's not under warranty anymore.

Looks like this is going to be a life changing event for me.
I have been a Chev guy since I bought my 1st NEW CAR in
1975. In fact I still drive a 1986 S-10 Blazer while my
newer S-10 (2000) sits safely in my garage most of the time
only comming out to play when towing my boat out of town
or a long road trip.

I have resisted buying Toyota only because I try to buy
American Made products whenever given the choice. But
depending on how Chev/GM handles this for me may push
me over to Toyota for my next purchase.

This electrical issue is well documented on various web sites
with hundreds of complaints to GM. So far they have resisted
doing much to make it right for the consumer.

Enough crying in my beer for now. Too many fish out
there that need catching.

There's no such thing as an "American car" anymore. Buy a Toyota. You'll be very happy.

Come on over to the dark side. Buy a Toyota.

i drive a dodge truck now... before that- i was GM loyal...

After reading your last post, all I can say is good luck and I hope the cost isn't to extreme. Sometime taking a vehicle to the dealership really sucks when it comes to cost but you have no choice but to have them work on and reprogram the vehilce.

Classic Chev resolved my Impala
issue today.... KINDA
To the tune of $500.00 out of my wallet.

Defective BCM, imagine that.

Just as the hundreds of reports suggested.

Thanks for your replies (emails recvd).
I know I was kinda hard on you and the entire
GM family. But as you can imagine I have a
rather bitter taste in my mouth for GM now.
Knowingly NOT standing behind their defective product.

If you know of any "Secret" GM plan to help offset
my costs involved today I would appriciate
hearing about it. From the internet posts
I have read, several people have had GM pay at
least a portion of the cost for the BCM.
My 30 plus years of GM loyality took a severe knife
in the back the last few days.

Ok, this will Offically -END- my 1st rant of 2008 and
hopefully my last.

Carry-on!

note to self: Consider TUNDRA in your next truck purchase.
