2009 MDX Power remains on after turning off car and opening door.

Hello All,

So I have a 2009 mdx with navi, and it seems that the car is not cutting power to things like the radio after I have turned off the car and opened the door. For example, I can enter the car with no keys and turn the radio on and listen to music. My Battery is dying overnight and its getting really annoying.

Any ideas?

What I have already tried - I pulled the fuses for the radio (inevitably the radio, locks, and interior lights), I have tried to reset by removing the battery. Any other ideas?

Thanks a million, this forum is great!

Hey I recently had a similar problem with my '09 acura MDX so I went to the dealer and had them run a draw test. Turned out the bluetooth was running when my car was off. Sadly the only solution was to replace the bluetooth component or disable it.
