[begin rant]

This was the rabbit hole that I didn't want to go down, but I saw a $3 handheld clicker/counter at a big box store a couple of weeks ago... so I got it. I just wanted to see just how many times the engine stop/start occurs.

Each time the engine stopped, I clicked it once. I don't click if the engine stops for more than 5 seconds.(like at an actual red light)

Over the last 10 days, the counter reached 286 over a total distance of 167 miles driven. That means the engine stopped and restarted unnecessarily for more than 28 times per day on average.

The majority stops are less than 2 seconds long, thanks to all the stop signs in my area. Pardon my French, but that's total connerie. At this rate, the engine will perform auto stop/start for no good reason more than 10,000 times in a year.(based on my expected 6000 miles per year) At best, in a year, it will save me a couple gallons of gas or about $6.50 based on this week's gas price.($3.18/gal for premium at the local Costco)

Well.. guess I'll just have to make sure it's deactivated each time I get into the car.

I've never stayed at a Holiday Inn Express, so I can't possibly smarter than BMW engineers or perform brain surgery. Having said that, does it really take engineer to realize that 10,000 extra unnecessary engine stops and restarts can't possibly be a good thing?(for the longevity of the engine or the environment)

The engine and starter is designed to take a huge number of interactions for this very reason. Have starters failed more because of the stop/start - NO.

Why well as above they are engineered to meet the requirements of the car in a very detailed way from the power surge the benefit or for the EU models adding extra power into the mix (Extra 11bhp and even faster starts the US doesn't get).

Enjoy the car stop worry about shadows and chill out.

Start/stop tech isn't new. My 2014 328 has it (88K miles and still going strong). Hybrids have had this tech even longer.

Show me on owners forums where there has been any alarming uptick in failures of starters or other engine parts? I've never seen anyone in the 3-series forums posting that it actually happened to them - only that the sky "may" be falling.

BMW launched this system in 2007. 16 years ago. That says everything you need to know.

That's true... I guess the only thing that it will screw up is me

I had a Prius a few years ago and even the frequent engine on/off annoying to no end.

Guess my next vehicle will have be a full EV.

I bet the OG 2007 system is smoother than what’s in our brand new x1’s. Talk about going backwards…

Always in sport mode, 0 start stops.

Not a chance. The U11 X1 stop/start is much smoother than my '14 328. The issue isn't how smooth the stop/start is. The issue is the transmission hesitation and, for me, that the "stop" kicks in before the car comes to a full stop. But the actual stopping/starting of the engine is noticeably better than my last car.

so it's not normal when my X1's engine automatically stops and restarts, even after being driven for half an hour, the whole car shakes a little as if it's restarting from a freezing cold morning?(like a gas-powered lawnmower starting up) The tech at the dealer said that it was normal....

My 328 was much more noticeable when restarting, and the dealer told me it was functioning normally. My X1 is much smoother; but the dealer told me it's normal for the engine to shut down before the car comes to a complete stop, like when pulling into my garage. So I try and remember to shift to L when pulling in.

Overthinking this...just put it in sports mode if you're concerned about future starter failures...mind you, it's under warranty. I doubt most of us will own this vehicle beyond 4 years anyway...and wait a sec, don't you have a 7 year warranty? So who cares if the starter did fail due to a bazillion stop/starts

It's so strange they decided to cut the engine while still rolling. Our 1st Gen only cuts out at a full stop. It's even better implemented in our Toyota where you apply a little extra brake pressure at a stop to cut the engine. There are definitely times it'd be better to have a choice to keep the engine on. Really surprised it cuts out before it's stopped

Not only that, but in my 328, if you only have the brake depressed 1/4 or 1/2 way, it won't shut down. You have to put good pressure on the brake pedal for the shutdown to occur. I preferred that.

YUP! Thats how the Toyota works too
