Agreed with Mountain.


Also, thanks to 16WhiteSS for that bit of HMI info.

It happend to me several times, and after a long examination and countless trips to the dealership, i found that I love my car so much I am sleep walking and sitting in it for hours a night! LOL

I took mine in yesterday after jump starting it, they put the car on their machine and it came back that it was at 400 cca instead of the 760 cca, so I get a new battery on Monday, of course they told me that my car was setting up for too long of which I know that is BS, but hey I get a new battery.

Jumped the car, drove around at 50-55 for about 30 minutes and the car is back up to 12.4 volts.

I’ve read some of the battery drain posts on the forum, but haven’t seen anyone with an issue similar to what is going on with my car. I think I found the problem and would like to post it here in case anyone else has this issue.

If all the lights are off in the garage, the car is locked and “sleeping”, I can see the back light on the LCD screen for the gauge cluster turns on for 30 seconds, then off for 5 seconds, and keeps repeating this behavior. I tested this a couple times by unlocking, turning on the ignition, then back off, locking and storing the key in its normal spot. It is repeatable and sometimes the steering wheel lights would flash every time the LCD backlight came on. It’s very hard to see with any amount of light and even hard to see before your eyes adjust to the darkness after turning the lights out. One off the tests the back light stayed off longer, about 20 seconds instead of 5.

My car is a 2016 Camaro 2SS 6 speed, 4700 miles and the only mods are Mishimoto catch can and SLP skip-shift eliminator. Both mods have been on the car for 6 months+ before having this issue.

I'm going to make an appointment at the dealer tomorrow and will post the results.

Sorry to revive an old thread, but I am having exactly same issue!
I did some parasitic testing and found Fuse F16 DISPLAY is draining over 502mA.

Anyone know if I can just buy an HMI at any dealership and replace mine without the need of reprogramming?

I imported my 2017 ZL1...

Thanks

All these electronic stuff these cars have now.


Give us a car built like 1969 only with our engine and performance we have in the c6!

A few weeks after taking delivery in March, I had an issue with it holding a charge. It was also leaving the Infotainment screen on. I got into it and did a software update and problem gone.
