Feeling your pain...

To generate more awareness I've shared/mentioned today this thread on the Lexus UK fb page: https://www.facebook.com/LexusUK/photos/a.167188123332400.56950.108330332551513/764115380306335/?type=1

Lexus UK have already responded that they are aware (which we already knew from this thread) but let's just hope that the more people who becomes aware of the issue, the more pressure it will generate on Lexus...

I left a Saab 9-3 TiD 150hp automatic for this car. The Saab was a real beauty to drive - in my opinion it beat the IS300h on anything related to performance and drive train. Just wish I could have my Saab back!

Oh no, don't say that. I am (was) aiming for an IS 300h myself but this transmission/drivetrain issue has really put me off. :( I'm starting to think I need to get the 450h (GS) instead which, to the best of my knowledge, doesn't suffer from this, right...?

It also means going from a fully-equipped IS to a minimally-equipped GS, but I suppose I can live with that if I must (on the plus-side, the 450h is quite powerful which I love - I soooo wish 450h was available for the IS also).

Haven't been back to the dealer yet and wasn't using it for the last few weeks. Will be bringing it in for winter tyres week after next and will hand in the list of defects. Are you feeling absolutely nothing, even a slight shudder or vibration; I noticed something similar on my girlfriend's Auris hybrid?

I don't have a 300h (yet) myself. ;)

Many thanks Clearline and Dannemare. I think I'll bring it back to the dealer then.

What did the dealer say?

The Telegraph review is online now at http://www.telegraph.co.uk/motoring/car-manufacturers/lexus/10435322/Lexus-IS300h-F-Sport-review.html

My IS300h is 3 months old now and I've driven about 3800 miles. I noticed this first about 2 months ago and it seems to be appearing more and more: When driving between 50 and 60mph in Economy mode the transmission gives a kind of vibration that one can just about feel. I could only describe it as a kind of light harmonic distortion, as if the electric motor and the engine are not in sync. If you stay at the same speed it gets quite irritating, especially compared to the car's usual smooth and quiet composure. In Normal or Sport it seems to occur less, or at least for a smaller speed range.

I haven't discussed this with my dealer yet as it might be 'normal,' so I'd like to hear if it's just me, my car, or more that us!

Has anyone else a similar experience?

Many thanks

Oh no. I certain hope this is something what will be rectified for you asap. If there is something I cannot live with, it is engine/drivetrain issues.

Before looking into the 300h, I was hooked on the new BMW 328i, but try a search for "malfunction" on http://www.f30post.com/forums/ and a million posts pop up with owners who have problems causing limp mode and whatnot.

John, please keep us posted on how things turn out.
