Hi all I just joined the site! My friend found it and sent me the link! Well I have a 2005 GS! I got it this past spring. My question is with the skyhook system I was driving to the NJ Shore and when going over expansion joints the car had a swimming motion front to rear when in sport mode when in normal it was much worse!! I took it to the dealer and they said they checked everything and the one thing that was off was tire air presure. But the car was better when I got it back but it's still there just not as bad! My service guy said he took a 2006 GS out and said t was the same! Has anyone had the same issue and if so were they able to fix it! Could it be something with the system that would not show up on the computer and might just be the shock? Well besides that I love the car so if I could have a better idea of what might be rong I would be greatfull! Since the car is in the shop 4 the winter it would give them a chance to work on it if there is something to be worked on!
