Soon after I purchase my Impala I began to experience a rhythmic vibration from 25mph thru 65mph. It would oscillate from a soft almost unnoticeable vibration to a significantly noticeable jerking in your seat. (I could look over at the empty passenger seat and watch it giggle like crazy)

Initially the dealer changed two tires and turned my front rotors. the vibration would lessen a little but never went away. The vibration was obviously having an effect on the wear of my tires causing cupping and scalloping. The dealer would balance and rotate my tires placing the worse tires on the rear to lessen the affects. Sometimes they would also fill my tires with nitrogen thinking it would soften the vibration.

We still seem to be chasing the problem...

Ever Since 5,032 Miles and only owning my vehicle 7 months I have been dealing with a shake in my vehicle and it's eating up my tires!!!! The dealer tried to blame my shake on having a tire that was out of round. But I replaced all 4 of the Icky Goodyear Integrity tires that the car came with at 10,400 miles. I didn't cheap out because i planned on keeping the car for a long time and put 4 brand new cooper touring CS4's on my vehicle. Low and behold, the shake is still there. Now more than ever it has become that droning annouying vibration that the dealer for some reason is now blaming on my currently chopped tires again. And GM believes the lies from the dealer that the shake is gone. I even eliminated the possibility of tires causing shake when the dealer put wheels and tires from a new car on the lot on my vehicle and allowed me to drive it approx 25miles. The shake still existed starting at 20-25mph and going right up through to 65mph. The only difference was that there was no hum on the road from my feathered tires. Anyone else have this problem and find a resolution ??? Tired of shaking while driving
