You can add me to the list. Either it turns on and then immediately hesitates like it’s not getting enough fuel and then recovers normal idle RPM. Or it turns over and runs for a second and goes off. Happens every 10-15 times I drive. I wish BMW would issue a recall because I mentioned this to my dealer and they couldn’t diagnose it.

I wonder if there is any connection to this issue and this other thread. Anyone else with both issues?

I had a very first batch begin of last year and had a recall on fuel pump and some software.

Mine guess would be the fuel pump

Welp, I finally gave up and took the car to the dealership. Of course the thing started fine every time for them. ¯\_(O_o)_/¯ Guess I am going to try the fuel cleaner mentioned above and see if that helps.

Had this happen to me about a year after use. 24K miles. I took it into service and they replaced the fuel pump saying the pressure was too low at the initial startup.

They installed a gauge to monitor the fuel pump pressure when it was stalling or dropping RPMs at startup, and found the pressure to be too low during those times through this method. They replaced the pump and monitored the pump pressure again and it was all good.

I think you might be better off just having the pump replaced.

I just wanted to give a quick update on my experience here so far with the Lucas lubricant. So after the dealership said they couldn't find anything I ordered this stuff (link above) off Amazon. I have run through 2 tanks of gas so far (using the Lucas lubricant in both tanks), and the car has not died on startup. The dealership even agreed that since they can't reproduce the problem that the Lucas lubricant was good stuff and worth trying.

Sorry mine friend but you don't need this on new car!

Fuel pump is most likely the problem. It was a issue from the gecko.

While I don't disagree with you, but when the dealership can't replicate it and won't do anything about it, what else am I left to do?

Just make a video and keep reporting
They can't fix it it's a lemon for you and get a new one

Just a general assumption/question... could it be shitty gas quality?

No. I am using 93 octane, usually Shell. Its evidently a low pressure fuel pump issue. Will let you know, I am getting a new one installed on Friday.

Described the repetitive problem. They agreed that it sounds like a fuel pump issue. We shall see.

I had both high and low pumps replaced about 2 weeks ago and haven’t had issue since. Yet. Can’t say whether was low or high but the combo so far works.

Car was in for a couple things. They didn’t reproduce until about 5 days in an I got a text from Foreman telling me he reproduced both. The immediate shut down and also the multi cranks before start. So that helped bmw say yes to replacements! Back in shop now
For other issues but so far the starting issue seems solved. For now.

Thought I was but no. They couldn't reproduce issue so will have to wait. Should be a recall on this as so many reporting it.

Most likely it will, mine died in mid cornering

That was coupe years ago, it was one of the first on the market.
