Thank you for the response Regarding the parking brake I have read that since it is an electronic brake it has caused battery drain since it is engaged while the car is off.
No, it doesn't use power just to keep the brake on. There is an actuator that activates a physical brake mechanism that sits inside the rear wheels, instead of the traditional cable. It's only using power for a few seconds right after you hit the switch. This is a common feature on new cars, my previous car had one as well.

the EPB yellow light soon goes out on it's own, not sure how quick but probably like any of the electric system (like lights etc) that maybe on that turn off automatically (usually after 30 seconds if set that way) (I'll try to remember to watch for it next time I turn the car off). I know it's never on when I get back in the car when parked overnight even though I've never touch the EPB switch.
Interesting. If i do not disengage the pking brake, and let it do its thing, when i stsrt the vehicle it is lit up until i disengage it or press the throttle to auto disengage. Hmmm

Correct but the light does go off after a while and comes back on after start
Agree. Some of the posts seem to confuse whether the light and or brake stays on. I'm sure the brake stays on, but as you said -not the light. I don't know exactly how it works, but as Quix said, I don't think it is using any power after the car is turned off.
