So today in stop and go traffic the 500L put out a nice cloud of smelly smoke then started shifting a bit more harshly. Just under 1800 miles on it. Happened very near to the dealer so I just changed my course to the service department. Service guy says this happens occasionally on the DDCT, they do a relearn on the clutch and transmission and he hasn't seen any cars come back a second time for this. I guess I'll find out, but I'm not thrilled to have an issue like this on a 1800 mile car. Two interesting things: 1) Since I bought the car at the end of December, Fiat has been moved from the building it was in to a small building on what was once the used car lot. And they opened a Chrysler/Dodge/Jeep/Ram dealership in the building where Fiat used to be. 2) There were no 2015 300 models in stock, just one 300C Platinum in transit that supposedly has an almost $51k MSRP but still only has the V6 engine.
