Super strange C6 problem this morning.

Came into the garage to leave for work in my other car, and the 4 way flashers were going off on the C6. Took me a second to realize what was happening, but I ran inside to grab the fob. I drove it last night and thought maybe I accidentally hit the hazard light button when I was turning off my radar detector. Well the button was off, and turning it on and back off again did nothing. So I tried to start the car, but there was not enough juice to turn it over. And turning it back off and into accessory mode still did nothing. Also the window came down half way by itself when I opened the door. Turning the car back off again still did nothing. None of the fob buttons would also do anything like unlocking or locking.

So I decided rather than let it die all the way, I would disconnect the battery, and put my charger on it for the day and check back when I get home.

Anyone heard of this before. The car started doing this by itself at some point in the middle of the night or early morning.

The only difference is the car was tuned a last week. Other than that no aftermarket accessories whatsoever.

the newer BCM/modules don't like when voltage drops below 11 if its ~10 volt it will shut down the majority of systems to try to make sure you can drive the rest of the way home 9v your dead

battery looks like it could only be 2 years old at very most, looks like dealer should cover that too

It's a Delco, not the best batteries out there. I've seen the terminals just pull out of the battery.

Optima's are not what they used to be, I'm a big Interstate guy. I use them in all of my vehicles at work and home.

If you're close to me I can get you a hook up.

Optimas blow now.. Well, I know the red tops do first hand. Interstate batteries are really good, also vatozone duralast batteries are pretty solid. I've had the same one in my jag for over 8 years now.

I'd skip the Optima.

I agree with the Duralast, no experience with the Interstate.

Farm and fleet batteries ftw. Same exact warranty as any auto store battery for cheaper. My $100 battery at autozone was $60 at farm and fleet.

You guys are forgetting that corvette C6s eat batteries. They are known for draining batteries dry after a week from sitting. And putting the car in reverse no longer applies because it was supposedly fixed in 06. But they still need to be put on a trickle charger weekly. Sucks. But any new battey would probably be ok for a while.

I told my service guy about it having e85 and not to put gas in it or flash it. He was cool with it. So is the mechanic. Besides they said it was either the bcm or the hazard switch. Nothing to do with the ECM or any tuning. That can be proved.
