Dealership relationships are huge. It's no different than the rear bumper clip issue on the X5's. There are constant reports of it occurring yet there was never a recall. My dealership was great and fixed it with no questions asked as they were aware of the problem, but others haven't been so lucky.

Again, just a guess.
If you check the '13 brochure online, all 7s minus the 750Li/750xLi have 90 AH batteries, those two now have 105. If this information is accurate it looks like BMW has realized there was a problem and put a different battery in. It's strange the AH7 and the 760Li still have 90AH batteries, again according to the brochure.

Brought my car in for service. One of my complaints is the infamous “Increased Battery Discharge” problem. Just got a call from my advisor stating I left my headlamps on for two and half hours at one point. I said that’s impossible because I always have them set to “Auto”. Nevertheless, he said he “charged” the battery and that it appears to be fine now (which I don’t believe because since having the problem, I’ve gone on several 45+ minutes drives, which should have “charged” the battery, after which I was still experiencing the problem). ANYWAY, what I’d like to know is, hypothetically, if the headlamps were in the manual “on” position (which they were not), does the car automatically cut them off as a precaution after a certain amount of time? We have a Lexus that does so… Can't believe this bs. :|

As I mentioned earlier, my SA told me that I cannot leave the key fob in the car. It must be removed and the doors locked while in the garage. This somehow shuts everything down so that there is no draw on the battery. Knock on wood, since I have been taking the key fob out of the car, I have not had any problem. I have not been locking as suggested; guess I’m a rebel, lol.

Bottom line----- Do not leave your key fob in the car while it is parked in the garage at night. Remove it and lock the doors.

Thank you for your insight, but I don't leave the key in the car and always lock the car, I also always leave the headlamp switch on Auto; have no reason not to. Going to ask to view a print out of where they're stating I left my lights on; complete rubbish, absolute lies; honestly can't believe it's gotten to this point.

Ok, just wanted to throw that out there again in case it can help you or someone else.

I would be interested if they will show you any type of print out. While following this forum, I have heard statements like this before that the SA said the car shows this or that. Maybe someone with actual experience can confirm/deny what the car can actually report.

Cannot begin to describe how upset I am.

Shop foreman said I left my parking lights on and the battery won't be covered. I said I always leave my lights on Auto. He said parking lights are activated by the turn signal stalk and showed me how to turn them on. I said I didn't even know about the feature, much less how to activate it, and that the car should cut off anything accidentally left on after a certain amount of time - to prevent battery drain. He said not with the parking lights. Got nowhere with asking for the printout; he said the report is BMW property and confidential!? Service advisor said a new battery would be $700 ($325 + labor for installation and programming)!? Absolute BS. Dishonoring warranty work on a $100k+ car with a mere 22k miles on the clock / 2 hours labor to "program" a battery. Are we in the twilight zone or something? WHAT THE HELL IS WRONG WITH THIS POS COMPANY (AND ITS DEALER NETWORK)? Can't help but think that this is some big joke. Taking this up with the General Manager (Service Manager is useless, as I know corporate to be too). Even if I drop $700 on a new battery, I'm not letting this go. Can't believe it's come to this. Complete disgrace. Total shame. Any advice / insight welcome.

Otherwise, does Mercedes or Audi have these battery problems, and if so, how do they handle same?

If your 2011 has less than 50k miles, it's covered bumper to bumper including all the wear and tear items which includes a faulty battery! It sounds like you have a ****ty SA.

Thumbs down

I agree with coole65i, this is BS. I am even more skeptical now that they will not show you the printout. Good luck with the General Manager. Hopefully he/she will have some common sense and recognize that you are a good customer and take care of this. Not to mention compensating you for all of your wasted time on this. Keep us posted.

TOTAL Crap!!! Go to another dealer, and then file a major complaint with BMWNA! No, Audi and Mercedes do not have battery issues. Audi has their own issues, and personally I would be more comfortable in an S-Class. We've had 3 S-Classes between 1998 and 2008, and they were very, very reliable. Our one S500 was a 3rd car, and would honestly sit outside sometimes for weeks & weeks....and she started right up every time. We used to go back and forth from Germany and Sweden, and we always left our S-Classes at the airport, because we never had to worry about battery issues!!

Thank you for all of the support, Gentlemen.

Can't believe it's come to this. Have owned Mercedes-Benz, Land Rover, Lexus and Chevrolet and I've never had to deal with any of this nonsense; not referring to just this, but to the ownership experience as a whole.

Will keep you posted.

Good news: General Manager of dealer states they’re going to goodwill the battery. Crazy I had to take it up with him and crazy they’re “goodwilling” it instead of “warrantying” it, but such is the game corporate plays. Thank you for your support everyone.

Could a software issue have cause this? At one point I noticed a key data report stated there was a new “Software Integration Level” available, but whenever I ask my service advisor he states there are no updates. How do I find out what my car has and what’s available?

Glad to hear they are taking care of it, no matter what they call it. Sorry can’t help with the software question.

You shouldn’t have to keep your 100k car on a battery tender when you don’t drive it for a few days.

True but what can we do right. I had similar issues with my e92, actually had to call out roadside assistance twice because my car wouldn't start and my BMW dealer refused to address the issue.

Potential solutions for BMW:

1. Add bigger batteries
2. Add integrated power cords
3. Remove electronic and electrical features from cars
4. Run more items off the engine than electric motors (like steering)
5. Have features draw less power (be more efficient)

Any others I'm mssing?

I had issues with an older car before and I bought one of those $75 Costco power starters. It's got the leads for jumping any battery, a light and a built-in air compressor as well. I used to charge it every six weeks and then just keep it in my trunk. It weighted less than 20 pounds and saved my behind numerous times. Even better I jump-started at least a half-dozen other vehicles in the time that I owned it. No having to pull your car up to theirs, open the hood, rev your engine, etc.

True it's a pain to keep in your car the whole time but it might just save you from having to call roadside assistance and wait. And no, this should never be a topic of discussion for THE premeire luxury sedan from a premeire luxury brand!

My BMW dealership did the same for me. supposedly they eat the cost of it. A code came up on mine saying that the interior lights were left on, so the factory warranty wouldn't cover it. It's such BS, but since I only had my car for 3 months they took care of it.

My experience is that interior lights time out after 20 min or so, unless engine is on. I'm not sure if this goes for all lights, like trunk etc.

ALSO, when experiencing the “increased battery discharge” / “charge battery” problem and the car is started with the side view mirrors folded in, there are times the mirrors do not deploy upon driving off or pressing the button on the driver’s door, where it takes 5-10 minutes of driving before they can be deployed. This is EXCEPTIONALLY dangerous and I don’t understand why it happens when other features work (i.e.: windows, seats, instrument cluster, radio, HVAC, heated and cooled seats) even under the “increased battery discharge” / “charge battery” situations. Is there any way to “code” this so power goes to the mirrors upon startup, without needing to drive 5-10 minutes with them folded?

Not a good situation. Can you manually (I mean physically) push the mirrors out as an override. I would be very wary about driving a car without the mirrors - I'm worried I forget to do a side check.

Since purchasing my 7 3wks ago and reading these forums..I've been getting more and more paranoid about the 7. To reduce my chances of the battery dying I have since purchased a battery tender and leave it on once a week. While I was doing more research I came across this:

"To save energy and reduce the vehicle’s fuel consumption, this system controls the times at which the alternator charges the battery. Conventionally, a car’s alternator runs continuously and thus charging is always available to the battery; in the 7 Series, it charges only when the vehicle is decelerating or braking; otherwise, it freewheels, drawing virtually no power from the engine. An electronically controlled clutch, somewhat similar to that used with the air-conditioning compressor, is added to engage and disengage the alternator."


If I am to read this correctly, the only time the battery is charged during driving is when decelerating or braking. Does that mean that when I'm driving at a constant speed on the freeway for a distance of say 30/40 miles, the alternator never kicks in and the battery isn't charged? I've noticed during freeway driving that the regenerative meter rarely goes into the blue. If that is the case, am I better off in stop and go traffic?? I hate the fact that I do have to use the tender at all. The best part? My neighbor came over and asked me if my car was a plug in hybrid!
