Vibration/engine "labouring" In Higher Gears

[RNL]

Hi, All

Not a mechanic by any means and need some help

Recently purchased an IS 220d, as a swop for my volvo

It's a 2006 and only has 15400 genuine miles on it

Had to take it back to volvo as there is a strong vibration felt through the steering wheel and floor pan and even the rear view mirror vibrates

To stop the vibration I have to wait until it reaches 45mph before changing up from 3rd to 4th, 64mph before changing from 4th to 5th, 78mph before changing up to 6th

If I change up before, to put in to right gear, the car seriously vibrates and I'm afraid if I continue something may go seriously wrong

It feels as if the car is being driven in too high a gear for the speed of the car

There are no warning lights on ! ! !

Volvo have taken it back to Lexus who have "cleaned out EGR - refit, checked DTCs none stored No Bullitins regarding this model"

Don't know what this means, but the car is still vibrating

Has anybody any ideas or help as to how to reectify or what to do before something major goes wrong

Don't know what the vibration through the steering wheel is, could be a slightly buckled wheel or sticking brake calliper? Just guessing.

The vibrating rear view mirror is a re call issue and Lexus should fix it for free, common problem. Lexus Cardiff changed my brother in law's for free as it was under a certain mileage which yours must be if only on 15k.
