Hi,

New to the forum so apologies if i’m not following any rules here.
I have been searching for a solution to resolve vibration issues and shift issues in my 2015 IS200t Australian spec currently 95km.

I have already inspected this car with several mechanics but no one can find the real cause of this issue

some time car stuck at 4 th gear and wont change gear unless I stop the car or change to manual mode and change using shift stick.

car feels very rough to drive as well. I can believe that I’m driving a lexus. some cheap cars feels better that this

has anyone having similar issues or found a solution?

few things I done.

- transmission service
- reset transmission software and updated software
-checked mounts

Any help greatly appreciatated!
