I have a 300C but my mom has a 300 touring. I have noticed that sometimes, her car jolts hard when take it out of park. I mean a really big jolt (accompanied by a loud thud)!
Oh yea, my 06' C had the water/transmission problem. I first noticed it with less than 400 miles on it. The car would shutter and shake at about 40 or 50 mph while accelerating. It was not good.
The dealership flushed my system 3 times and re-routed something. The guy told me that water from the a/c was getting into the transmission. The car has 1,600 miles on it and it seems to be O.K. (I Hope).
