We're deviating a bit here Rayaans, but it was on the discussion below. CVT vibrations - very irritating. Problem was fixed with a workaround after I had it for about a year. Lexus Belgium ignored my rants, but one of the moderators of the forum slapped a comment on Lexus UK's Facebook page and I was contacted shortly afterwards to come in for a fix to the ECU. Coincidence?

No harm in moaning if you can't wax lyrical all the time. Many thanks to this forum for getting Lexus to fix a serious problem some of us had with our transmission. If Lexus only would read these blogs regularly it might get some good ideas that would keep their customer base.

3 years to improve things. Curious to try out the 2017 model to see how far they got!

Indeed... but so many beemers on the road. Was also considering the new 330e plug-in but it's just more of the same. Nope, I'll go full-hog this time: electric is the future, hope Elon can make the model 3 seriously reliable by the 400,000th! Sorry Lexus, but you were just not listening :(

With 110,000km on the clock I can definitely say it's the most reliable car I've ever had, but Lexus' conservatism is not going to do them many favours. Personally I'd be quite happy with a slightly less reliable car if used cutting-edge technology, but when you look at it seriously the Lexus tech is quite crap for 2016/2017; even the light sensors, auto wipers, adaptive cruise control are terrible! And not even having a decent gearbox is the ultimate in playing it safe. Also, unless I'm seriously mistaken, I don't see Lexus looking into plug-in hybrid or all-electric. I dared challenge my dealer with these statements, only to be arrogantly rebuffed with the claim that serious drivers don't see merit in fancy tech on the dash. My departing words should have been that, even though I might be the 400,000th on the list, I can't half wait for the invitation to on-line configure my Tesla Model 3! For my next service, I'll have a bumper sticker saying 'My next car is a Tesla'!

Has anybody had the chance to see the infotainment system on the 2017 model, and if so, what's your impression compared to the previous version? Probably a dumb question, but seeing as it's mainly just new software, what are the chances Lexus will offer it as a retrofit to the older models? At my last service just two weeks ago, my dealer wasn't even aware that the new model had an 'improved' infotainment system and went into typical denial model when I asked if there would be any major updates for the lousy present system. Happy holidays all!

I stand corrected! Indeed, 10% is a bit on the high side; it's more like 7-8% at 120kph but seems to be on a sliding scale with higher discrepancies at lower speeds. Not a UK car, I'm in Belgium. Compared it to my Coyote which gives the same speed as my Garmin. Used the same gear in an Opel Corsa and it was within 3%, just like my old Saab 93. Thought it might be a Japanese safety thing it inherited because my wife's Toyota Auris is also around the same tolerances. Can't trust their advertised CO2 figures, so don't trust the speedo either! :))

Mine is in kph. The speedo on the IS300h always shows 10% faster than you're actually driving (for whatever reason I don't know). I checked with a Coyote and at exactly 200km/h (around 220 on the clock) she stopped accelerating.

... if you hear the vibration, paddle down a 'gear' and it should go; then you know you have the problem. But as it's been 'fixed' more than a year ago, I doubt you have much to fear.

Hi John, http://www.lexusownersclub.co.uk/forum/topic/86868-potential-manufacturing-defect/ should do it. Haven't you been informed of the fix by your dealer (well, it's actually more of a work-around)? It's an ECU update. We've had ours in Europe since 3 weeks ago. Like I said, it doesn't remove the resonance completely but in my experience it moves it to a much narrower range of RPM which make it more bearable. Last thing to say to Lexus is that it's resolved! I'd suspect it's still a mechanical problem. See you on the other topic...

Hello DoNotBuyIS300h, You should move to the 'Potential Manufacturing Defect' post as that's where the topic is hottest. There is a 'fix' for the problem which some of us have had done. It hasn't cleared the issue completely but makes it a lot more bearable.

Has anyone else had the work-around done except Tore and me? Would like to know if you noticed a difference.

Wow, 2nd generation heated seats must have been really poor. On my IS300h I can hardly feel the heat, and the ventilation seemed to be ok for the first few months but now all I can feel is a tickle in my bum. I asked them to check the heated seats at the first servicing but they said they were ok. Mind you, I'm coming from a Saab, and those guys know (sorry, knew) a lot about cold weather.

After driving with the problem for nigh on 10 months, and noticing a great improvement with the "work-around" it suddenly dawned on me that I don't actually know how the car is supposed to feel at 80 - 100km/h. I notice a lot of things happening under the hood that don't happen at other speeds, is this right? Now I've changed garage, I'll ask for a loan of another IS300, which I should have done in the first place and not wasted time. Funny that they're sending somebody from Brussels as I actually live there and Lexus Brussels never offered me to have an expert look at the car :( .

Well, after about 20km on the motorway it feels like a major improvement. Not completely gone, I felt, but the resonance is certainly over a much shorter range of RPM. Certainly worth the upgrade.
