hey so lately its been draining the battery if i dont drive it for 2 days and now the battery is shot(least of my concerns)
it gave me the annoying security light so i did the relearn and and cranked up but wont start, i switched the key off and the security lighs blink again and i have to do the re learn again just to try and get it to crank up again but it fails to fire up. i did this thing over and over no luck.
any tips?
thanks

 

When the BCM is faulty it can cause a battery drain from my understanding. I would check the BCM for signs of water intrusion clean and re-seat the connectors and put it back in. If you still have the issue then I would try replacing the BCM.

 

Could also be a bad ignition cylinder. A chip in the cylinder passes the VAT code to the BCM which must match what's stored in the BCM.

 

my radio draws the radio on my car..2.2 amps which is to much,3 diff radios do it,it could be the amp,but I don't have another one to test..my ignition had to be replaced too..it didn't learn the key until you left it on for 15 min...

 

It turned out to be a faulty battery. I was surprised. It's not even a year old. But yea something is drawing current. The right side fuse panel has a bcm fuse blown and every time I swap it, it blows instantly. I think it's time to go to ththe rapists and get my bcm changed. But I'm broke. Cant afford 400+$ on this. I'm gna disconnect the battery every night till I figure something out. Next time I go in to fix the recall on the ignition switch I'll see if they can give me a deal

 

I got my switch changed out.they sell them on ebay for like 70 bucks..
