BMW admits ASS destroys your F30

I'm headed for Munich tomorrow to ED my MY12 ZSL 335i.

I stopped by a local dealer today while running errands to see if they had any F series key fobs (they didn't).

They only had one launch MY12 left -- an Alpine White ZML 328i.

I am excited, of course, about getting my car before the end of the week, so I sat for a moment in their car...to take in the ambiance. :-)

Hmmm....looks like the printed owner's manual is in the glove box. Let's take a look. Wow! There's a Quick Reference booklet! Cool, I'll be able to read that the first night in the hotel instead of digesting the whole Owner's Manual...strange that this document isn't on bmwusa.com in the "My Car" section of Owner's Manuals. Let's check out the index at the back to see what's in it. No index, but there's a an "Appendix" saying that any updates to the Owner's Manual can be found in this appendix.

Odd, there's an update about "Fuel consumption," reading, in part, "Certain vehicle components may experience additional wear as a result of this system."

Man, did they bury that! A hugely important disclosure concealed in an appendix of a shortened reference, designed to be used maybe once or twice. It's as if they didn't want anyone to see it -- but they covered themselves by printing the disclaimer somewhere. It's like all those footnotes about the wheels made of butter you see in the brochures; the have to disclose that BMW wheels and tires are pothole bait because if they don't, they'll get sued. (In Mass., everything BUT cars come with an implied warranty of merchantability. IOW, products have to be useful for their intended purpose. I wish this applied to BMW wheels and tires.)

You even have to know what "system" they are talking about because they don't even bother to name ASS in this "update." (Take a look for yourself; I took cellphone photos of the front and back covers and the appendix page of the guide.)

If ever there was a reason to code your F30 to remember the last position of ASS (I couldn't resist) or turn it off every time you start the car, this cryptic reference tucked away in an appendix of an obscure document is it. This is, I fear, deliberately designed to mislead consumers.

Shame on you, BMW.

Auto start stop has been used in other brands for years now with no major known problems. I use it and i'm generally happy with it, but then again I will only have this car for 3 years

So who exactly is this ass that destroyed my BMW.
I always figured it was the ass who decided to equip it with RFTs.

Shame on you, BMW.
You mean that ASS button? If you try to switch it off every time you start the car, I can see how that button can have additional wear.

There's no question that it would cause additional wear on the starter, plugs, wires and maybe a few other components. Will it matter? Likely not. It's probably the difference between the starter failing at the 200K mile mark and the 150K mile mark... which for those of us who don't keep our cars for 15+ years just doesn't matter.

1. I never buy the first model year of a new car, I would rather have them sort the bugs out first.
2. If going with a brand that I don't know well, a new model, etc, I will often lease.

I leased. We'll see how this car does over 3 years. If it is a rock star then maybe I will buy one and drive for 7+ years in 2015. At that point I would assume there will be even more reliability data.

Haven't hybrids like the Prius been using Auto Start-Stop technology since it was introduced in the late 1990's? I'm definitely not claiming to be any sort of expert on the Prius by any means but if premature engine component wear-failure on hybrid vehicles doesn't seem to be discussed very often (especially compared to topics such as battery replacement) then you would think BMW's implementation of an A.S.S. system would not seriously impact anything prematurely. I for one am fine with the system on my car in most situations (and can turn it off in the other scenarios where I want to).

Hybrids use a totally different system to restart the car. The large electric drive motor is used to start the gas/diesel motor, not a ring and pinion arrangement.

As long as we still have the option to disable ASS it doesn't bother me too much.
