2020 Cayenne Downshift Issues Low Speeds

Hey, I'm new to the forum. This is my 1st Porsche.

I just got a 2020 Cayenne (base model). When downshifting (especially from 2 to 1), the car "jerks" forward. This is most noticeable at 12 mphs as the RPMs go from 900 to 1200 even if I'm on the brake. It happens at 3 to 2, but 2 to 1 is more pronounced. When braking at low speeds the car seems like it's "fighting" the shift. To compensate, I've been braking harder. I can't believe this is the way Porsche intends the transmission to operate.

Porsche advised that: (1) this is "the way it is" and (2) all the Cayenne models have this "feature" and will "improve" over time as it is a smart transmission that adapts to your driving.

I've seen a few similar posts on Rennlist.

Is something I should make a stink over or is this just "the way it is".

@PMSnyder, I am new to the forum as well and concerned that no one replied to your request. I just joined and posted some questions but it seems that the forum is not very active compare to the Macan forum that I am part of where there are a few very active members including myself who jump in all over any new posts and helping right away. I wish I could help you but I do not have the new Cayenne yet (2020) but with my 2014 base when this behavior was happening it was the transfer case and it was replaced even out of warranty. I realize that the transmission is not the same since they changed the manufacturer but this behavior to me sounds like a transfer case and not normal. The only advice I can give you is to go to the dealer and drive another base.
