Replying to: wunderbread (Feb 08, 2008 8:20 pm) Wunderbred, Please post the bulletin # you wrote of in item # 31. I'm having vibration and rumbling noises at speeds between 40-65 MPH. Dealer want's me to let the tires run in for 7-8,000 miles. The vibration is worse at 42-43 MPH and in a slight pull or trying to maintain that speed straight and level. Help!

Replying to: 9119911 (Apr 03, 2008 5:38 pm) The Technical Service Bulletin (TSB) = 08-07-30-044 (reflashed TCM with software modification per bulletin). I had the same issue as you are describing. Totally resolved after applying this TSB by my dealer. There is a warning with the TSB that the mpg may go down. Haven't noticed anything significant sofar. It made all the difference to me. Highly recommend the solution. My CTS is once again just one great car. Wouldn't trade it for anything else.
