It feels like it starts in the front and rolls to the back of the car. Do not notice it in the steering wheel. I got a call from the service department and they told me their guy drove it for 15 minutes and did not notice anything They said I could come over and ride with someone to see if it could be duplicated. So, I jumped in my loaner mini fan and headed over. The service manager came out, (working there a week) and went with me. He has been in the auto business for many years as a mechanic and tire guy and he teaches auto mechanics at a local college. Plus he owns a sportscar! Anyway, long story...he noticed the vibration as soon as he got it to speed, said it was coming from the rearend. Assured me that they would take the proper steps to fix the problem. I am going to think positive and believe they will get it taken care of. I am ready to put the top down and ride. The sun is finally coming out again
