Well I was excited to finally take my R on a longer than and hour trip for the first time since I got it. Ended up not going so well though. I noticed that every bump i hit on the highway my car felt like it would shift back and forth a little. To compare, it was kind of like hitting a quick patch of ice sliding and then hitting the road again. Is this what this side hop is that everyone is talking about? It was actually kind of scary especially when giong 75mph. This was a very noticeable shift mostly in the rear end. Also anytime I would hit a bump with my cruise control on, the bump would deactivate the cruise control. Then to top is all off on my way home I was filling up at the gas station and I rolled my window down and it went down crooked so I tried to push the window button to roll it up and the window glass broke so now the window doesn't go down or up and just makes a loud crunching noise. By the way it was raining and 54 degrees the whole ride home with the window stuck open and broke. Back to the dealer AGAIN!!!
