2024 c63s hybrid battery issues
Have had a c63s e performance a couple of months. Past two nights, park it, battery is full. Wake up and go down and the hybrid battery is drained to zero. Thoughts?

Not noticing anything thus far. Charge seems to be retained overnight for me. Let me know if it resolves or what the dealership ends up saying. All the best.

Sounds like something is keeping the vehicle awake, draining the battery, the temperature also might affect it, doesn't sould like a big issue might be some software glitch keeping systems alive when it should be in standby or hibernate mode.

Had something similar happen on another car because of the dashcam wired into the ciggy port. Is anything plugged into any of the ports / usbs?

That could be it too but for OP it is the E Performance battery not simply the 12V that is getting drained.

Was having the same problem. Service advisor recommended checking pre-entry climate control settings. If you have "activation when unlocked" checked, try turning that off and see if it fixes the issue.
