BMWs manual I think says you only need to drive about a minimum of 100 miles a month to keep the batt charged...

SO if thats the case how come they dont give you a new Batt and see what it fixes on your car?

...I guess because now I ordered a new car and they don't want to mess with my old car. The "too short" commute of 8 miles a day is a pathetic excuse (the engine is running 20-30 minutes per day). My other cars never had any issues with it. I mean, a car for $65,000 should be able to handle this, or am I missing something here?

Dude 8 miles is fine... my mom drives 3 mins to work a day. about 1.5 miles each way. Her mercedes is doing fine. 1300 miles in about 4 months...

I'm pushing 41K miles. Car is driven plenty. I have what appears to be the battery issue as well.

Mine's going in next week. We'll see what happens...

mine was acting up recently more than usual,i also have new symptom now:more often than not sound mute occurs along with "anti-trap window deactivated" message that appears only for a split second,however,anti-trap feature is operational when i test it right away,which makes me think it is definately "voltage drop" related.
I am taking my car in next week for reg maintenance(22K miles),check engine/increased emissions message,creaking back seat and clicking/tapping sound from steering column upon unlocking the car.
Will post results.

It's baaaack...

Clearly this issue only happens in colder temperatures. I didn't happen at all last Spring or this past Summer. This morning, it was about 38 degrees (F) and just a mile or so from my home, with the seat and steering wheel heaters on, the radio cut out two or three times during a downshift.

This afternoon, it happend a bunch of times on my way home. Same temperature, same scenario. Mostly on downshifts but I think it happend briefly on an upshift too.

I think the good news is it seems to be happening more frequently so it might be easier to duplicate at the dealership. Something tells me I'm going to be getting a new battery...

Rudy,you are not alone-mine started to act up again today-first time since last winter/spring...has to be colder temperatures...i did not have seat heating or steering wheel heating on though.I almost forgot about this issue...but it came back!

Mine happend for about 5 days last year during the winter. Never happened again...It will be interesting to see what winter brings...

It's back and it's at its worst! Anybody has been able to fix it? Now it's happening more often than not...Rudy,please...
