that seems like a dangerous thing at 4-way stop intersections where people sometimes have a hard time deciding who gets to go first.

Driving out north yesterday I was on the highway and came to a left turn with no stop, so I was rolling slowly waiting for a gap in oncoming traffic to make the turn. A gap opens up big enough for two cars to turn safely. I initiated the turn (still rolling slowly, motor on) and pressed the gas. For a good second or so, I'm sitting in oncoming traffic with ZERO acceleration, pedal unresponsive. Had it been a smaller gap in traffic this would have been terrifying. Not sure if it is due to the Auto Start/Stop, or the throttle tuning, or both, but I'm writing a letter to BMWNA because this is a potential safety issue.

I really wish at the very least it would turn off only when at a complete stop, there are tons of instances when driving when I need to slow down to less than 5mph but not stop fully, and then accelerate again.

I’ve watched the reviews of the X1 where the reviewers called it out for a delay in certain circumstances between applying the throttle and getting the response that was expected, and that’s with the engine running. I personally noticed it on a test drive of a 2023 when I found out how long it waits to kick down after you floor it as if to pass at a moderate speed.

Our older X1 has a small throttle delay from a stop or a slow roll, but putting the transmission (not the drive mode) into sport gets rid of it. So it’s something that’s been deliberately programmed into the throttle or transmission tuning, for some reason, and no car software update has ever addressed it. Kind of a bummer that they seem to be continuing that tradition in the new one.

Yeah, my 430i had it too, but in certain instances it seems worse in the X1.

I have had this in the X1 a couple of times. It is super annoying and dangerous just sitting there in traffic with no response. I also used to get it with my M135i so it is not exclusive to the X1. Happily never experienced anything even remotely like it with my M4. I think it is just a matter of the way the engine lags sometimes and interacts with the laggy DCT. Two lots of lag gives you the situation where you sit there with nothing

The brake hold is also a factor, because in my F30, when I took my foot off the brake, the car would restart. But if the brake hold is on, that doesn't happen.

I have my Auto Hold turned off. I tried it once out of curiosity, but I’m undecided if I like it or not.

can auto hold stay turned off until the drive choose to turn it back on?

Yes. On the throttle delay issues that does seem really poor. My wife noticed a bit of a hesitation on a roundabout, was when she was rolling and the engine hadn’t stopped so it wasn’t a stop start issue. I suspect it’s something to do with the DCT clutch maybe, either way it’s not a good thing.

I think a small part of it may be the DCT, but mostly software tuning. Only because in sport mode the throttle response is so much better, almost perfect.
