Have a battery drain issue on my 2008 Honda Accord. I have changed the starter, battery, alternator. Everything in the car is stock no stereo/amp/sub.
Iv looked into the ac relay and replaced it. Any other people run into this issue ? Car does have a air bag light on and side air bag. Iv noticed that the car locks on its own when I get out if I have my windows rolled down and they will go up on there own. Iv noticed that the doors will keep trying to lock when the battery is “low”

 

I recently traced a similar issue on a TL (platform cousin to your Accord) to the hands-free Bluetooth module. When driven daily the battery was able to hold enough charge to start in the mornings, but over a long weekend the module drained enough for a no-start condition.

 

Windows and locking is definitely after market. Do a parasitic draw test, a tester at harbor freight is $10 and you get to keep it invest in fuses for the thing as you'll burn them out by mistake.
50ma is average draw with car turned off

let us know how it goes

 

fixed the battery drain prob, the driver door control panel switch for the power widows and locks was causing the draw, I replaced it with a used one from eBay and problem solved.
