Dead Battery Systems

Over the course of the last week we’ve had to jump start our TLX at least 20 times. AAA came out to jump once and checked battery, starter and alternator and showed all good. Had to jump it after that visit. Today took the car to Acura dealer and they can’t find any problems either.

Here’s a list of symptoms that we’ve noticed

1. Key FOB activates one ground light on right side mirror from inside the house.
2. Key FOB occasionally not working (batteries replaced in both FOB’s)
3. Jump start with Buick LaCrosse takes about 10 minutes of battery charging.
4. Starter clicks and lights go off when starter button depressed.
5. Jump start with BMW 328i starts the car up immediately.
6. Jump start with portable jump starter is immediate
7. Radio plays even if car doesn’t start

Any ideas out in Acura land? ECU?
