Auto Stop/Start - uncomfortable acceleration

Auto Stop/Start - uncomfortable acceleration
Most people hates this auto stop/start function but sometimes it's really useful depending on the traffic conditions.
I have noticed that it's very uncomfortable whenever I lifted my foot off brake to start and go. The vehicle attempts to accelerate and move forward (only a short distance though) as soon as the engine auto started.
Cayenne moves a little bit forward but very fast so I feel like that I lose a control over the vehicle as like an unintended acceleration, e.g., a recall of Lexus/Toyota.
Not comfortable at all since the vehicle moved although I didn't step on the gas pedal.
Anyone had this type of an acceleration issue when the auto start function engages?
It's for 2012 Cayenne V6.
Thanks!

I suppose it depends on the grade; uphill, flat, downhill would likely make a difference. I very much dislike the auto stop/start feature, perhaps only because that's not how I'm used to driving an automatic. I've not encountered any sudden movement based on the restart but then I don't tend to allow the vehicle to sit 'in gear' when I'm stopped. I hold the brake until it's time to go.
At least with 2015 (and 2016?) and previous model years you can disable the stop/start. 2017 loses the option to disable it.

I hate it and never use it in my 2014 GTS. The times I have tried it though, definitely no surge forward or anything like that.
If you truly can't shut it off in newer model years, it would be a deal breaker for me considering another Cayenne.

On my wife's macan she saved the off mode with her key memory. I use it on and don't mind it so not sure if it saves to the memory when saving you seat settings to the key

What model year? Pre-2017 there were options. As of '17 there's no option to control it in the MFT, nor does it appear to be able to remember it with the key.

In my 2012 I hit the center console button once when I bought it to turn it off and it never came back on, no matter which key is used.

Thanks for all nice comments.
I turned off the function. I carefully checked the battery status during the vehicle is in the auto stop mode.
I noticed that the battery voltage continued to go down really fast especially at night & at the low outside temperature. This is another reason to turn off the auto/stop function.
Although it must be well designed for any circumstances, I think that there should be no benefits (by frequent stop/start) to batteries, ignition coils, spark plugs, etc.

Yeah, Start/Stop sucks ***** all the way around.
The OP can turn it off permanently in his 2012, but 2016+ Cayenne owners are stuck with having to turn it off every damn time we get in the car. The start/stop BS, inability to stay in SPORT mode, and having to hit navigation CONFIRM every time I get in -- these really make me hate Porsche (and many new cars) with all my heart. At least the seat-belt buzzer goes off after a minute or two; many cars don't do that...
Maybe my next car will be a nanny-free 1978 911.

While driving/idling at night, in the cold, there's going to be a LOT of things pulling on the electrical system. Heater blowers, vent actuator motors, wire defrosters in windows, all the running lights, the headlights, etc. The engine stop/starting doesn't seem likely to add 'enough' load to be a problem. Assuming the battery is in good condition. 3-5 years is the typical replacement cycle.

I don't like the auto stop/start feature. That alone is reason enough. I don't need vague worries about wear to justify it.
