Exactly. For me at least, this has occurred more frequently in the past couple of months. This past couple of days, I have disabled the Auto-Stop-Start because I've encountered too many situations lately where I'll be creeping in city driving traffic and the car comes to an intense jolting stop and the engine stops.

Sometimes a period of a second or more where it doesn’t pick the gear and engage...but I’ve never experienced that with the QX30. I think those of you that are experiencing the jerking symptoms either should take your car in to be checked out by the stealership or just haven’t 100% figured out the nuances of the tranny, no offense intended. Based on E or S mode, you can gauge pretty closely when the tranny is going to be shifting up or down. It’s moderately consistent in a couple different acceleration scenarios. If yours isn’t acting that way (predictable), I highly suggest having the dealership look at it while you’re still under warranty
Wanna trade cars? In all seriousness, city driving in first and second gear is highly unpredictable. Keep in mind, one of the cars I had before this was a Mercedes-Benz GLA, so I'm not new to the world of DCTs. The E mode in that car felt gutless, but still refined. Just a follow-up questions:
You mentioned you almost exclusively drive in S mode. What specifically made you stop using E mode? Was it a lack of power or poor shifting characteristics?
Ifou're driving during rush traffic, how does your car handle 0-35 MPH and then back down to a complete stop? My QX30 will exhibit the jerky feeling in 1st, between 1st and 2nd, and then have a smooth, seamless upshift until 4th. When idling back to a complete stop, downshifts from 2nd to 1st results in an unrefined jerk.
I think I might just have to drive 90 miles to the closest dealership and take the service manager for a drive.
