It is not the emergency brakes. It works like this when coming to a stop with nothing around. As someone suggested, perhaps not all of us have cars that are calibrated correctly. I'm glad your car doesn't have this problem.

I was posting recently that mine does this, but for me, it only happens when starting from a stop and then trying to creep with my foot partially on the brake. It just abruptly stops

Ours never abruptly stops … unless there’s bushes or something that the parking sesnsors see and think is a wall! I suspect if anyone’s having the car abruptly stop itself, it’s your automated emergency braking, not auto hold…

It’s not. I can’t speak for everyones vehicle. Mine is not emergency stopping. Mine is stopping in a way it never did prior to 3.1/Auto Hold despite my driving style, well established, not changing.

I park daily in an entirely too small garage with aids strategically set up, including a foam block that I hit with my hood periodically, which orients me into the two inch window in which I can park my car and successfully close the overhead door without hitting the rear. Passengers must enter the passenger side only outside of the garage, as the passenger side doors cannot open. In other words, it’s tight. Warning tones coming out of all the speakers. It has never stopped on its own.

Similar speed starting from a stop and attempting to creep slow, it now stops abruptly post-3.1.

You should take it in and ask the dealer to check it out… it should only come to an abrupt stop if it either senses an obstruction or you’re driving without a seatbelt on and lift off the seat.

Yes, of course. But I’m posting about it to see if I’m alone. Also my curiosity to know why. I think the pressure sensing posited above is interesting. I’ve always thought mine had odd brake pressure/feel.

Again, no, it happens with nothing around and it is not emergency braking. As for taking it in to the dealer, it is a minor inconvenience and I'm not gambling on what condition the car will be after they try to "fix" it

Also, I'm pretty sure emergency braking isn't even operational at the super low speeds where this happens.

Emergency braking is most active at lower speeds. I’ve had mine come to an abrupt halt when it sees a bush or a tree close behind me, or even the street when backing down an angle driveway. All I can tell you is auto hold never takes affect unless I bring the car to a complete stop and then push a little bit harder on the brake pedal so if you’re experiencing the car stop by yourself, it isn’t auto hold.

Yeah, if you’re feeling weirdness in the brake pedal, take it in. Mine feels perfectly natural and I can’t tell when it switches from region to mechanical brakes.

This is my take…
The auto hold holds the car in place. My BMW and ID4 do this. When engaged, my bimmer holds its place without creeping, or slipping on a hill. The ID4 behaves the same. With the auto hold on, it does not creep nor slip.

The auto hold holds the car in place. It does not brake the car.
I don't know the correct terminology but my ID4 stops itself when it senses while in motion. Let's call that an emergency brake. Does the auto hold come on AFTER the emergency brake? I don't know but I am guessing it does.

I realize I may not be adding anything useful to the discussion here. I am sorry for that. But as far as I can tell, MY ID4's auto hold is just as good, or bad, as my ICE bimmer's.

Agree with you… I think that I’ve always been confused by folks who think that Auto Hold causes the car to stop on its own, and suspect they’re confusing it with other functions in the car, like AEB or how it jumps into Park if you aren’t wearing your seatbelt while backing up and lift out of the seat (some folks are used to doing that).

Spitballing: what if the car thinks it’s supposed to be stopped based on one input, but another input says it’s not, and it stops as a programmed reaction.

A question I’ve always had about Auto Hold: what happens if I get rear ended? If it’s mechanical and has stopped based on a certain light brake pressure, does it know immediately apply more pressure? If there are sensory inputs and computer logic that says “if car is supposed to be stopped but is not stopped then stop” that are in play during a rear end collision, then it’s not out of the realm of possibility that that same logic (which was not present prior to Auto Hold), could be faulty in certain circumstances.

@d287 would it make more sense to address the semantics of the question as “the general software enhancements related to braking, including Auto Hold, released in version 3.1”? Whatever you want to call this, two members here have reported an unexpected braking behavior.

I don’t know what happens when you get rear ended (and hope never to find out) but I’ve felt it adjust the brake pressure when stopped on a steep incline. It seems to sense the wheel rotation and increase brake pressure accordingly.

That's true. And as a general rule, unexpected behavior is to be avoided while driving or braking.

I don't think anyone here is not believing or dismissing the problem with auto hold after the 3.1 upgrade. That is certainly not my intention.

This is a very interesting question.
I don't know how it really works but if I were programming the logic, the brake system's response would depend on if the auto hold was on or off before the impact.
If the auto hold was off, the car would simply roll forward.
If the auto hold was on, there would be skid marks.

In the end, to me, to auto hold or not auto hold is a personal choice, like Travel Assist. I like TA, but I know many here enjoy driving without any assistance.

If you like or want to use the auto hold and if it doesn't work for you as expected, it is time to visit the dealership. All someone like me can do is give one data point that the auto hold can work without sudden braking.

Like @LeFennecFox feels, it’s not really all that big enough of a deal to me to schedule a special appointment. I’ll mention it the next time I’m in. I know how to make happen (creep slow from a stop), and I know how to make it not happen (creep as fast as the car wants to from a stop). I’m more interested in the talking about it part of it here on VWIDTalk. I’m not one to come on here and slam VW for stuff, especially when they’re honestly only little quirks.

I disabled Auto Hold, as well.

I can tolerate no Auto Hold while out driving. For maneuvering in our parking garage, having no Auto Hold is essential.

I use it all the time. Doesn't bother me while parking in the garage going forward or reverse. YMMV

And this is why Volkswagen created the option to put it in the pulldown menu.

I just wish they’d do the same for “Creep” mode… drove a Polestar yesterday and it is such a nice way of setting it up…

They have a “One Pedal Drive” mode with Off / Low / Standard - this is like D vs B. (Our B mode is in between low and standard.)

Then they have “Creep” mode with Off / On. Creep off is like auto hold but it stops itself without need for the brake pedal, and Creep on works just like ID.4.

The thing VW does better is make it easier to change D/B on the fly with the shifter. Polestar requires you to go two taps in the touchscreen to change this, meaning you’re not going to do it as easily while driving. (I often find myself changing D to B when approaching a downhill or traffic or something.)

Again, I'm glad your car doesn't have this problem. As far as I'm aware, you've never driven my ID.4, so please stop telling me I don't know I'm talking about. I've already proven to myself that the car brings itself to a lurching halt without emergency braking and only in B mode not in D mode (which certainly also shouldn't affect emergency braking). It is clear to me from this thread that this is my car doing something it is not supposed to do, and that's good news. But still my car (and seemingly others) also have this problem.

Yes, sounds like, you have an issue… which is why I suggested you take to the dealer! Also, try using D mode in low speed maneuvering… May not make a difference but I usually drive in D, especially in the driveway. And how do you know it isn’t emergency braking?
