Gateway computer?

 

Our family owned a 2005 Acura TL and the battery would go dead if we let it sit for 4 -7 days. This is a known defect with the bluetooth devices in some Acura's. Even though the car is off and fob (s) are miles away the defective part causes the car to keep searching for a blue tooth connection. A small drain for sure but over 4 -7 days it drains the battery. Once new blue tooth components were changed the problem went away.

Just picked up a used 2013 ES350. To be safe I will put one of the mini jump start batteries in the trunk. Fingers crossed.

 

Wow, You guys are the best. My battery died and I charged it to find it did it again when the light would not go off. Put it on Manual rather than Auto and everything was fine. The I walked around and opened the Doors to see if the Open Door Light cam on. All cam on instantly except the Driver side. It was delay and sometimes for a long time. BAM - that was it. Ordered one on Ebay for $14,00 and will replace it tomorrow. Thanks guys. You lead me to the problem.

 

Did the dealer ever isolate the cause of the battery drain? If so, what was the fix? Thanks!!!!

 

I found this today. Not sure if it covers your model or not.
