Hi Dazed, we've moved this topic over to "Potential Manufacturing Defect" if you'd like to follow it. Everybody reporting the problem (just 3 of us so far, unfortunately, so welcome to the club!) agrees it happens between around 80 - 90kph when the engine is between 1300 and 1400 rpm, and it goes away if you paddle down a 'virtual' gear. I'm pretty sure there is a solution because most owners don't have the problem - perhaps a little electronic tweaking of the CVT. Please don't let this turn you off the car. I'm bringing mine in to the dealer in a few weeks, and will be taking all the comments with me, so watch this space.
Hi Dazed, at least three more of us in France have reported this vibration problem, two on F-Sport and one on Executive version. And as stated on the other topic, it has been reported an other Toyota hybrid models as well.
