Well, I just purchased a 2006 Highlander and the car exhibits a rocking or wobbling. Unfortunately, the car did not do this during the test drive but started shortly after. I took the car to the Toyota dealer because I noticed there was a TSB on this issue and they reprogrammed/updated the hybrid software to the most recent version. While this update took care of most of the rocking the car still rocks noticeably every time I drive it.

Has anyone else had this issue? Did the TSB take care of all the rocking/wobbling sensation or was their more that had to be done to get ride of the annoying and somewhat disconcerting rocking?
