We bought a 2012 SXT in March 2012 and we also started having issues with the transmission shuddering when coming to a stop. While the dealership was driving it around to figure out the issue it shuddered for them while accelerating. They have now had the car for 3 weeks, going back and forth with Chrylser about it. Chyrsler told them to take apart the transmission and inspect some things, and NOW we are waiting for a part that is on BACKORDER. In the meantime we can't drive our Brand New car b/c the transmission has been taken apart. Luckily the dealership is paying for the rental car. If this doesn't fix the issue, I'm going to push that this be a Lemon. This is the 2nd time we had the car in the shop for this same issue.
