C-300 Pulling to right after a bump?

Hello,

I have a brand new C-300 (well a few months old). Here in Wisconsin we have some pretty rough highways.

At around 75 MPH+ if you go over a bump, the car seems to want to pull to the right once the weight stabalizes. These are not huge bumps with a sign that says "bump". Just regular old bumps that are say where two slabs change height 1" or something like that, like when you leave asphalt and hit concrete going over a bridge.

I've tried the car in both sport and economy settings to see if that would do anything with the suspension but that doesn't help.

If the road is flat, or smooth the car handles perfectly and drives straight - no pull what so ever.

Anyone have any ideas? Should I take it in?

My situation is probably different, not like what you said about a sudden 1" height change.

Yesterday at 80 MPH, I drove over a bump more like a wide sine wave. Since speed was high, it tossed my car so high for the first time that I though it might cause trouble (either car damage or I lose control). After car settled down, I didn't feel anything abnormal, still driving at the same speed.

If I were you, I'd take it in. Although four year warranty, I'd solve any potential problem as early as possible.

**Update**

Dealer found a faulty shock in the back of the car.

Most noticeable at higher speeds, and was also making the car pull to the left.
