My vehicle has a very rough idle-vibrating at idle or stopped and not shifting properly-gear slipping. There is sluggish acceleration or jerking and the problem worsens while at a stop light/stop sign or at times when making a turn. The RPM gs between 200-300 when I accelerate to go from a stop and the car revs as it slowly hits 20 mph and then jerks into the 30-40mph on the streets. I took it to the dealer January 2025 where they could not duplicate the concern, and all they did was a TCM judder improvement update for the DCT. The problem was dismissed as being an issue associated with the DCT and was told that unless a warning light turned on or my car broke down on me, they couldn’t do anything more. The service representative advised that if I am in stop and go traffic and the car starts vibrating or shaking, I should pull over the side and turn off the car for a few minutes before continuing on my way. It has been less than 2 months and I have to take it back to the dealer so they can run diagnostics on it again. Same issues, no warning lights on the dashboard indicating there is a problem, but I am not comfortable driving the car anymore.
