Whenever I go over a sharp bump or speed bump the the car seems to have a secondary thud immediately after the initial thud from the obstruction. It's as if something is lose. I've taken it to the dealer and they are claiming they can't find anything wrong it but I know something isn't right. Wondering if anyone has had a similar issue and what the dealer did to fix it?

PS - CLS55

do you get the noise in the rear? if so its the exhaust hitting the rear bumper. nothing really to worry about

no, thats not the exhaust. It is the airmatic noise... people say it sounds like a dead body rollin around in the trunk.

it happens to me to. I thought is the spare tire on the back or something there.. but it could be from the airmatic. I don't think the mufler would hit the bumper (unless you modified something).

Have the thud in the trunk too. Normal or something we can do about it?
