Manual. The problem arose in two ways. Either: When the car started and turned the lights on (dipped) automatically, or I flick the stalk to full beam and then back to dipped In both scenarios, especially in colder weather, it seems, it would leave my offside headlight about half way between proper dipped and full beam, maybe 1 out of 4 or 5 times. Hope that helps.

I didn't update this thread since my original post, sorry, but I'm happy to report I did get it sorted on my car. I stuck some sheets of paper to the inside back wall of my garage, cycled my lights through the 'proper' dipped and full-beam settings and drew on the sheets where the light *should* end for each. I then recorded some video with my phone as I flicked several times from dipped to full beam and back manually and showed within about a minute that coming down from full to dipped didn't always work - it clearly stopped about half way between. I presented this to my Lexus dealer and they replaced the light unit under warranty. I did tell them I considered it a safety concern because it absolutely is, but I think they would have replaced it in any case as the evidence was clear. I haven't noticed any issues with it over the last two years.

The first time I needed to replace the tyres on my IS, I went for Dunlop Sport Maxx. I hated them! In cold weather (below about 7C) they skipped and juddered, especially when I was reversing and turning, even gently, well away from full lock. I considered winter tyres but here in the south west there are probably only 2 days in a typical year when full winter tyres would be really useful. So, when I needed to change them a few months ago, before winter set in, I decided to try Michelin Crossclimates. They were SO much better. As it stands I'll be sticking to them in future unless I find they degrade too quickly, but so far there doesn't seem to be any signs that they might.

Can confirm. I've tracked just over 31,000 miles in my IS300h on fuelly.com. Average is 46.5mpg. The summer months give about 10mpg more than the winter. I don't use Eco mode and usually have aircon running.

There's a funny (IMHO - though I'm sure it's not meant to be) instructional video on YouTube for using a Toyota paint set but of course it's actually the same thing. How to use Toyota car touch up paint set and fix scratch in paint I love how the chap, Peter Finn, goes to quite some pains to [try to] explain those instructions and then show us how to get a "professional" finish but . . . ah, now I don't want to spoil it for you!

Me too! I reported it to Lexus a year ago after I'd had my IS300H Exec for a couple of weeks, figuring perhaps they were just set too high but was assured they were MOT-legal. Come into winter again now, of course, and have also had people flashing me angrily but have also come to realise the offside lamp does sometimes clearly light up higher and brighter on the road and the back of the car in front when it should be dipped. I haven't tried the dip-twice trick but will do so. Seems like I should book a new visit to Lexus Bristol, armed with this info, thanks!

I'm going to have to go and check re: route guidance volume. You could be right; it looks like I forgot rule #1: RTFM! I'll be down to just the one thing then. And on that topic, yes. I have done a little research and am fairly sure I can (and will) improve it by a few decibels but I believe human ears need about 3 decibels difference to notice any real difference so the improvement might not be as much as I'd really like. Sadly my local council have gone and resurfaced just about every road nearby with the typical cheap and nasty stone-chipping method. When I do get on a nice stretch of smooth asphalt(?) road surface it's a gorgeous feeling!

Seriously, the only things I think I could say I dislike are: - road/tyre noise because it really spoils the otherwise whisper-quiet drive, but that's probably more to do with the rubbish way our roads seem to be constructed and maintained than the car - satnav / entertainment system because a) the voice is a little too loud and b) I don't have the premium version so I can't update it myself and it does get caught out with revised road layouts from time-to-time. Um, that's it, I think. I can live with that!

Mildly interesting, maybe: I've had my IS300h for one year and one day today and have driven almost exactly 10,000 miles (just passed through that figure by about 20 miles this afternoon). I'm certainly happy with the fuel economy overall, though now we're heading into winter I know from last year that despite my best efforts it will drop by almost 10 mpg from where it is now. My poorest result, last February gave me 43.44mpg and my best, back in July was 52.93 (figures through fuelly.com) I received a 1-year courtesy call yesterday from Janet at Bristol Lexus, which was nice. Yes, I know she's looking forward to the point when she can legitimately start offering me an "amazing deal" on a new car but it was nice to hear from her.

I didn't think to record my fuel computer readings but Colin's figures seem to be pretty close to the ones I've been seeing: The computer does seem to overstate it by somewhere around 2.5 to 3.5 mpg. Having been tracking my experience on fuelly.com also, what struck me most was the enormous difference between fuel economy at (a very respectable) 43.4mpg in coldest part of winter - although here in the milder southwest it wasn't that cold, of course and my best in the summer at 52.9 - almost 10 miles per gallon difference. Wow!

Not if I have to store the car at -30C for 5 days before every journey! Brrrrr.

Ford Cortina, Hillman Hunter (don't ask!), Renault 5, Renault 19 1.4 Petrol, Renault 19 1.9L Turbo Diesel, Toyota Avensis 2.0L, which I admit isn't an exciting car but it served me so well for twelve and a half years and over 112,000 miles. A few niggles and hiccups along the way, of course, but generally oh so reliable!

Ouch! If they're right about the Lexus IS (2013-) then I am very sad to hear that. I hope they're not suggesting that Lexus have 'managed' the emissions in test environments as per VW Group and it's more that the test environment isn't "realistic". Assuming it's the latter then presumably Which? are in a position of being hard-pressed to put any cars as "Best Buy" unless they're pure electric..?

The bad weather, especially rain and therefore lots wet roads has definitely dragged my fuel economy down - I try to keep the car computer showing more than 50mpg but that's been elusive the last couple of tanks' full, but I'm still holding at 46.9mpg average as measured via fully.com. I'm delighted with that and am really looking forward to seeing what I can achieve when (if) we get some nice warm, dry, summer months.

​I walked to the cinema to watch Star Wars a couple of weeks ago. When I left at the end of the film it was absolutely piddling down. At that moment I genuinely thought it would have been great if I could have called my car to come and get me. About a week later (and by then with me finally just about dried out) I read about Tesla's first part of that eventual goal, with the whole coming out to you from the garage thing now being a part of their programming. I'm looking forward to it, though for the next Star Wars movie at least, perhaps I'll have to remember my umbrella.
