Investigations are proceeding as is my test-driving of Discovery 4's with the intent being that if I have to buy one it will have a sticker on the rear window... 'My 200 had a vibration that Toyota couldn't fix. I did it myself with this....'


It's interesting that we haven't had more people complain of a vibration here assuming it's a widespread issue. I have a very, very slight resonance in the steering wheel when ever I'm driving up a slight incline (the vehicle is under a bit of load) and the RPMs are at around 2000. Again, it's very slight but enough for my wife to ask, about it - and that says a lot!
Next time I'm in for service I'm going to ask about it and see if they have any bulletins.
