Thanks everyone for your replies. I will keep an eye and if this problem persists then will get camber bushes and arms checked by a mechanic.

Hi guys I need advise on something I discovered few days ago. 3 out of 4 wheels (except driver side front) were wearing from inside. As usual, few things I did were changed tyres and 4 wheel alignment. Wheel alignment guy said they can adjust toe but not camber. He said even Lexus can not adjust it as camber issue can be due to multiple suspension issues which needs investigating by a mechanic. Now I am puzzled as car drives fine and it was checked by a mechanic few weeks back and he did look at suspension parts which all look ok. I suspect as camber is not fixed, wheels might unevenly wear again and more importantly if there is any suspension issue it might get worse. Did any of you had this issue and know what to do and where to go to get this thoroughly checked and fixed? I have attached a picture of 4 wheel alignment which shows camber still out of tolerance.

Hi wharfhouse Yes, the button is switched on that's when this error comes up. When I switch it off then there is no error on dash and sensors don't work either way. Thanks

Hi folks Parking sensors didn't work since I bought this car few months back. These are factory fitted in my Advance model. Yesterday got it checked with an electrician and his computer said stays 'open' to all except front two centre ones which had status 'freeze'. He suggested we can guess that these two had different status so these are the faulty ones. Questions to you: 1. Did anyone else experienced this issue and how they got around it? 2. Is it common for these two front centre ones to fail as they get all the hit from front? 3. Where to buy? Lexus is quoting over £100 each 4. Is it an easy job to change it ourselves or does it need specialist electrician? 5. Does it need recoding/reset using a specialist diagnostic machine after replacing with new sensors? Thanks for your help as always!

Hi folks Does anyone know how many litres coolant do I need if I drain and refill coolant in both main coolant tank and inverter coolant tank. Thanks

Many thanks for your replies. These are very helpful to understand real life fuel consumption. It looks quite good (specially after facelift) for the size and luxury of this car.

thanks for replies. Is it right to say that premier and F-Sport models will suffer from lower mpg than executive models due to their size of tyres. If Premier is getting 42mpg on motorway then executive models will get e.g. 47mpg?

Hi I am considering buying GS300h. MPG wise I am trying to compare it with IS300h and these do not look too far from each other but I think if I go for GS300h, its a bigger, more luxurious and more comfortable car compared to IS300h. I understand IS300h drive may be a bit more sporty but I am not bothered by that. From what I can see GS300h had a facelift in 2016 and official mpg suggest the post facelift models have better mpg. I would like your expert opinion on the follow: 1. What is realistic average and motorway mpg that can be achieved? 2. Does the facelift model had some technical advancement that improved mpg. If yes, by how much? Thanks

Thanks you all for your kind contributions in sharing all these details with your opinions which are very valuable for me. thanks

Hi Linas and whafhouse If ES300h gives approximately similar fuel economy due to its drivetrain and newer version of hybrid system then it is an option I would consider. This is purely because I think you get a lot more comfort, specs and space in ES as compared to IS and of course it looks pretty good. The only issue is that as its newer and quite expensive when comparing like with like with IS (year and mileage), I might have to consider a higher mileage ES300h. I came across a 2019 model with 140k miles but as the warranty on hybrid battery is only covered till 150k I am getting confuse whether I should consider it or not? Its only 4 years old with one owner and full service history and a newer hybrid system means it should have plenty of life still left (but not covered by Lexus). Any thoughts are welcome.

You are all fantastic members of this group and I can not thank you enough for your helpful and detailed explanation of different models and specs of IS300h. I understand that fuel economy mainly depends on two factors. 1. driving style 2. size of tyres. 'Advance' version meets a good balance between value, specs and ride comfort. 'F-Sport' is the only version that comes with digital dash but F-Sport and Premier gets lower fuel economy mainly due to their tyre sizes (which I understand can be changed but might not go with rest of styling of the car). I now have some good level of information. Regardless of the trim I will chose, I will consider full Lexus history. Now slightly diverting from IS300h, I came across ES300h which of course is more expensive compared to IS but reading its real mpg figures on honest john it doesn't make sense that the size of the car ES300h is it still gets similar fuel economy as IS300h although ES300h also has a 2.5l 4 cylinder engine with hybrid battery same as IS300h? Is it due to any technological advancement in ES300h compared to IS300h that improved its fuel efficiency?

Thank for detailed response wharfhouse. What is the cost of annual Relax warranty (under 100k or 10 years)? I understand Lexus covers hybrid battery warranty up to 15 years (as long as checked by them each year) but does Lexus give any idea of expected lifetime of this battery. I was watching a few videos and experts say its not down to how many miles but its down to how many years it can last? is it true? If yes then how many years? 20,25,30 years? If there is a problem with hybrid battery or it dies, is it still possible to run the car on petrol or not? You mentioned when something goes wrong it can be expensive. What sort of things are reported to go wrong with these cars and is it normally after a certain age or miles? Sorry but repeating one of my questions earlier, is it possible to install 16'' wheels on advance/executive/luxury versions to get better fuel economy? thanks

Thanks for explaining wharfhouse. It is indeed a bit confusing at start but its slowly making some sense. Executive, Luxury and Advance is what I am struggling to decide but I have some useful information now to help me decide. Good to hear it didn't give you any trouble since 2016 and having done 94k miles. In terms of hybrid battery maintenance and warranty, does it require any maintenance or regular checks? I understand it has 15 years warranty as long as its checked annually by Lexus main dealer. In that sense, is it then ideal to buy a car that has full Lexus history and its hybrid battery is checked every year by Lexus, otherwise the 15 years hybrid battery warranty is void? What is expected lifetime of its hybrid battery? Is it measured by miles or years? thanks

Thanks Paul. Do you recommend having 'Advance' then. I think it depends on how long you kept it for and how satisfied you are with this version of IS 🙂 Where does 'Advance' sits when comparing low to high spec IS models? Above Executive and below Luxury? or 'Luxury' is another adopted name of 'Advance' and they are the same? If so, how is 'Executive' better than 'Luxury' in terms of its specs when Executive only have heated seats and Luxury has heated and cooling seats? Do you know which models have premier sound (I am not intending to buy F-Sport for reasons explained in previous post) thanks

Thanks for replies. I have few follow up question if you can help. I was actually considering 'Advance' version which is not listed in the reply. I wonder where does this fits in the below versions comparisons? SE>Sport>Luxury>Executive>F-Sport>Premier I also found that 'Executive' only has heated seats where as 'Luxury' has heated and cooling seats which puts Luxury on top of Executive. Isn't it or am I missing something? In terms of tyre sizes, Is it not possible to use 16'' SE tyres in Advance/Luxury/Executive models to get better fuel economy? I am trying to avoid F-Sport version due to its stiff suspension. I understand overall IS is a well road worthy car and this stiff suspension will not hugely makes any difference to its road grip etc. but I get your point on leather seats. Also, fuel economy is a consideration for me and I know F-Sport version returns the worst MPG. If MPG is a theoretical number then what does IS normally returns in real life as Average, city and Motorway driving in eco mode?
