Who wants to have to push a button every time you get in your car or let up on the brake at every stop, or adjust how hard you depress the brake when stopping? Instead of driving becoming a better experience over time, it is the opposite. Any way you look at it, ASS makes your car a POS.

"BMW of North America issued a recall for more than 105,000 of its vehicles over concerns their starter motor could overheat, posing a fire risk.

The recall involves certain BMW model year 2019-2020 X5, X7, 2020 3 Series Sedan, X6, 2020-2021 7 Series Sedan, 2020 8 Series Convertible, 8 Series Coupe and 2020 8 Series Gran Coupe vehicles."

Not a concern with these vehicles. Besides being beefed up, the starter motor is only used for cold starts, the others are done by the MH system.

The recall is not for the starter motor not being able to start the engine but rather if it can't then it could overheat/cause a fire under the right conditions if a person keeps trying it. The fix is a software update to prevent the continual use when not starting.

It should be the same. Does anyone with an ICE G60 have any inputs?

I don't think the conditions include the amount of pressure on the brake. As I recall, the interior of the vehicle has to be close enough to the set temperature, the oil temperature of the engine has to be high enough, the steering wheel can't be too far from centre, and the starter battery has to have sufficient charge.

The AC runs very, very low when the engine is off. It's not good at all in hot, sunny weather (especially when you've just started driving and things have yet to cool down). I could restart the engine if it got too hot in the car by turning the steering wheel a bit. On the old 3-series you could deactivate ASS with a dash button. Some coding tricks would have it remember the setting between restarts.

When setting off from a standstill the engine restart is pretty subtle, and is done by the time you get your foot off the brake and onto the gas. You can tell it happened but it's not a big deal. The same system in the 4-cylinder cars I've tried is a lot more noticeable. With either engine, if the car is not moving at restart it is quite jerky - unpleasantly so, IMO.

When I had the N55 I left the auto-start-stop enabled. Mostly it wasn't a big deal. If I were stuck in stop-go traffic in the hot sun I would occasionally disable it, but mostly I left it on.

I thought I was the only one that noticed the rough restart using the mild hybrid system at a standstill. Not noticeable if accelerating when the engine is off, but noticeable when starting at a standstill (if it times out and restarts the engine).

What's crazy is that the 12v starter motor seems smoother on cold start than the 48v starter generator restarting at a standstill.

Wonder if this can be fixed with a software update. Most mild hybrids don't have this issue, the start is almost imperceptible even from a standstill. Was smooth under all circumstances on latest S580 and Range Rover.

Honestly I could give a rats ass about the starter. By the time it breaks I probably won’t own the car anymore.

The ASS is stupid shit, period. Look at us talking about “the sweet spot” on the brake pedal. I’ve also found this sweet spot and its pathetic that I have to waste any thought on this so i can save a drop of gas and some liberal weenie can talk about how they’re saving the planet.

Yes I want my V8, I want my 550hp. I want my 212inch long car. And I want the car to shut off only when I shut it off.

Endless threads, complaints, work arounds, etc. The ASS is annoying and makes you feel like shit sitting in a stalled hot car at a red light. I tried to get used to it, but can’t. 10 months of owning my 760 and can’t get used to this stupid shit.

I’m so happy BMW added an off button, and I welcome a way to not even have to push that off button, because I know when I forget and the car stalls, it will be annoying.

F-you ASS!!!

Is there anything else you would like to add?

Can confirm. I tested a 550e and specifically paid attention to ASS transitions. The only way I could tell B58 kicked in/out was observing jumping consumption figures on the screen. I'm sure your ear gets trained with time, but it was a very pleasant surprise.

Concerns about the long-term engine health still stand though.

That’s definitely reassuring. I really never thought to pay attention during my 540 test drive. I think I was too intoxicated over the Star Trek like dash and low end torque to notice that. It did seem to start out on battery and transition to the engine during the initial move forward, if I recall correctly.

Yesterday while driving for no reason the roof shade opened by itself while driving. My wife was with me and asked why I opened it. Told her both hands were on the wheel as I was making a turn. She finally agrees this vehicle has got problems.

So there's that...LOL

PHEV is completely different from the mild hybrid. Mild hybrid uses a belt starter instead of a motor in the transmission. Really like the idea of the PHEV, I would have gotten that had it been available when I got my 530i.

The new mild hybrids, at least I6's/V8's, I think starting with the 2023 X7 no longer use a belt system but rather have the motor in the transmission.

I checked, and the 530i and 540i now have an ISM in the tranny. Not a BSM. Also when I test drove the 530/540 I did not notice any jumping when going from a stop to start on the freeway traffic.

So my 2024 530i has an ISG? I posted on another thread here recently and there is a ton of conflicting information out there. A lot of sources are saying BSG and some are saying ISG (including Wikipedia). I definitely see a starter generator on the belt system under the hood.
