Jump / Jerk / Lurch Shifting into R, and then again Shifting into D :(

Hello everyone,

I have a service appointment with my dealer tomorrow.

This past winter my car started doing the following:

If parked overnight on a very, very, very slight incline (my homeís driveway), upon startup and shifting into reverse, the car jumps and jerks backwards (while my foot is of course still on the brake). Furthermore, I do allow the car to warm up for a minute.

I know that this happens to all vehicles when parked on a steep incline, but Iíve had the car since new, itís never done this before, and it also only happens when cold out and upon cold start up; not again later in the day.

Then, in addition to the above, once the vehicle is out of the driveway, I shift into drive to make a left turn, and as I let off the brake the car moves / coasts a small amount and then jumps or lurches forward (while turning) and subsequently smooths out, with no further issue. This jump or lurch is shocking and violent.

Anything come to mind that I can relay to the service advisor / shop foreman?

Awful how I feel the need to consult this [most knowledgeable] forum on matters first before visiting the dealer; youíd think that a clear description of same would be sufficient to get down to the bottom of things with them; but no, not with our vehicles.

Thank you very much.

My 2012 has sane issue, dealer cant find reason. File has been sent to Germany no answer. It also happens more when I use spirt or sport plus. The vehicle shifts extra hard, kinda jerking from 1st to 2nd gear and also with foot on brake at stand still it lurches forward

Many thanks for your post.

Please kindly keep me posted with any updates you hear back from the dealer.

Best of luck.
