09 RT REar End "squirm" at highway speeds
I have an 09 RT that I've had about a month now. It has just over 4000 miles and I believe it has all factory suspension in it. When I bought it over 200 miles away I had a chance to drive it at speed on the highway. At the time it was rainy and windy and I noticed the rear end felt very squirmy for lack of a better term. I attributed it to the rain and wind and have since only driven it around town. Today I had the car on the open highway and again noticed the rear end moving around. I noticed it at 80 mph, but once I did, when paying attention I could feel it even as low as 60-65 mph. I have 2 months warranty left and if its an issue, despite my disdain for dealerships, I'd like to get it fixed. Is this normal? I have not seen other posts here about it so I am thinking it is not normal. I was driving the car lets just say in triple digits the night I brought it home and it seemed worse then at higher speeds.
