On going Vibration Issue
I've taken in to the dealer, but they say they are not allowed to drive at those speeds. So they offered to do a wheel balance and it actually seemed to solve it for about 2 days and now its back again. It really isn't so much the vibration, but more so the sound accompanied by it. I've made a previous thread about it, but I swear it sounds like the wind is making a "flapping" type of resonating sound. I can even hear it over the radio. My only guess was that it was tire related, but I've had the tires changed recently, even to a different brand, and seem to still have the issue. I'm clueless and the service dept. is clueless.
If there were something I liked to trade it in for, I would do it in a heartbeat because of this damned annoyance!
Can someone here drive 80mph and see if the car is quiet and vibrationless?!
never experienced that... sorry to hear you're experiencing it.I make mad dashes to the local mountains / desert from time to time and haven't had any problems or vibs at high speeds. Wife is always amazed how the CLS seems so solid & confident at high speeds compared to some of our other cars.
At low speed, I get the occasional "clunk" in the rear which is the air suspension not fully loaded at times, which bugs me for a car of this caliber.
Good luck... must suspension issue if you've already ruled out your wheels / tires.
Turbulence is the culprit. Some cars get this REAL bad at speed. The turbulence can turn into feeling like your inside a kick drum being pounded rapid fire.
Close the sunroof and roll up the windows. If it goes away, you found the gremlin.

Did you notice this vibration since you put the new bumper on... ive seen some carlson bumpers make wind noise
Could be one of several things.
Check the wheels for stones, nails etc.
Get a wheel alignment, check the rims - twice - or drop them off for testing.
Take the car to a shop that offers "High speed on the car wheel balancing"

I get turbulence around 40-50 and just crack one of the rear windows.
High speed vibration is often an indication of a wheel that is out of balance or a bent rim. It can also be a bent driveshaft or bad U-joint.

Too late to get it fixed as I just ordered an 09 CLS63 this morning. Diamond white metallic with ash interior and led tail lights.
You will notice immediately that "on the car wheel balancing" makes for a smoother ride, even on a car just balanced.

It's possible it is a bent wheel. I might try and get it rebalanced and have them check for it.
