Thanks for your response. No plans, just curious :D

Does anyone know the frontal area of the LS460? I know the CD is pretty low at 0.26 but trying to, randomly, find info on CDA but can't find it. Anyone? Thanks.

Maybe it's not occurred to you that some people feel the cold more than others? Maybe some people want a warmer seat than others? My heating system works fine, but I'm not talking about that, I'm talking about the seats :)

Thanks for clarifying. They are pretty rubbish in my opinion but I don't think it's because they're turning off early as they stay warm, but it is merely warm at best.

Hi, Just wondering really, are the heated seats in the LS460 a bit, well, crap? Mine get warm, but certainly not hot. I wondered whether it was just the driver's one so stuck the passenger one on and then sat in that after some time and again, it's warm, but certainly not as hot as many other cars. Just curious if that's the norm? Thanks in advance.

That's interesting, thanks! The car was taken to the garage and they were a bit stumped initially because their machine was showing all 5 wheels reporting pressures, temperatures etc but the car was still throwing a fault. They connected the OBD reader to it and the fault cleared itself. It was as if the reader told the car the pressures and the car was like "oh yeah, it's OK!" and it's been fine ever since. Many thanks.

So my TPMS warning light came on the other day asking me to get it looked at by a dealer. Same thing happened about 1 year ago, had 4 TPMS batteries replaced (all, bar the spare) and all was well. This time it wasn't reporting any pressures, so I held in the reset light under the dash and it read pressures for all tyres except for the spare. After 30mins of driving (ish) the error light came back on.Friend of mine took the wheel away, used a checker and sure enough, battery dead. He replaced the battery and the wheel it back in the boot. I have pressed the reset light, the dash says TPMS resetting....and then the error just comes straight back. Any thoughts as to why it won't go away? Does it need resetting with a diagnostics thing? Cheers.

That's very interesting thank you! Certainly doesn't look like it is the £5k fix many seem to say (or did say). Great news for peace of mind.

As per the title, my rack is fine (touch wood!) but does anyone actually rebuild the steering racks, should they fail? Or do you literally have to buy them new? I'd be surprised if nobody does. Does anyone know the cost of the part direct from Lexus, without labour? Cheers.

Perfect thanks! Seems like my current ones are too long, then!

Ah. Yeah I have measured them and they're 600mm/480mm (give or take) yet looking online that seems to be a rare combination to find!

If you buy in pairs of the same size, what size do you go for? Thanks

Interesting thread, I haven't read it all but I have an LS460. It's had a few minor issues but absolutely nothing remotely expensive. Only had it since November 2019 and it hasn't let me down (yet!). I read about the gearbox/radiator problem and had a new OEM radiator fitted out of precaution. Other than that, and general servicing I have had to replace 1 wheel bearing and I had to get the ride height sensors removed and thoroughly cleaned because at times the car was a bit "wonky" with its ride height, but that is now resolved and didn't require new parts. Overall it has been a very good car. There is always a risk of bigger bills with more complex cars, but the additional performance over an LS400 is very significant, coupled with (slightly) better economy and more creature comforts available (especially now I have a GROM unit fitted - I have full Android integration) means that, for me, those risks are worth it. The way I see it, I bought the car outright, it isn't really depreciating, and the monthly payments on a new car lease deal would easily pay for any unexpected servicing costs on the LS460, and I am driving an LS460 instead of some dreary 1.4L diesel hatchback or whatever.

Friend of mine runs a garage, I asked him for some new wiper blades, and when he went to fit them he said one was the right size and the other was too small, he didn't have a tape measure on him so asked me to measure mine. I have just done so and the driver's appears to be 600mm or so, and the passenger around 480mm. Yet, looking online, many appear to offer pairs of 600/400mm? What gives? Do people on here buy them individually, or as pairs? If pairs, where from!? Many thanks

Thanks! Unfortunately doesn't seem to show a great deal. Knowing oil temperature would be quite handy. Never mind! Many thanks for taking the time to reply.

On both of my previous BMW 7 series there have been a "hidden" menu to access various bits of information when driving such as oil temperature, coolant temperature and various other things. I was just curious if there was something similar for the LS460? For the E65 745i I had to get the ignition on, press and hold the trip reset button for around 10 seconds and then enter the last few digits of the VIN if I recall. Many thanks!

Thanks everyone. I'm not put off by the cost as such, if the system fails I'll almost certainly replace with the Lexus air set up as it left the factory. I was just curious as to whether it is worth changing it just to refresh the car, but I think I'll leave the money in the bank should it fail in the future. I can't say I've noticed a particularly bouncy ride and it recently had a service and MOT and nothing got picked up there so assume all is well.....?!

Obviously traditional springs and dampers degrade over time and are not as good as when new. Is the same true of air suspension, and is it to the same sort of extent as a traditional set up? I have heard some people say that the degradation is minimal and only if it becomes an issue with regards to wheel alignment is it a problem, otherwise it isn't far off how it was when it left the factory.....but when it does fail, it properly fails! Only reason I ask if that I am half tempted to spend some cash on the car and was wondering whether a suspension rebuild was something remotely worthwhile, but I've been told not to bother until it fails. I remember when I had an old BMW 745i (2004 car) I had all the springs and dampers changed, as well as bushes, control arms etc) after 2 struts were leaking (I decided I may as well do the whole lot) and the difference was pretty significant, but so was the difference to my bank balance Or should I just keep saving the cash for when a rainy day does come for the car? Cheers!

Managed to put in 68L of Tesco 99RON Momentum yesterday to brim the car. Not TOO expensive in today's world at 145.9p/L. MOT and full service (minus plugs and coolant) Thursday! As an aside, does anyone know if the differential oil needs changing on these? I assume so. Not sure when it was last done so I'll ask them to do that too.

Thanks for your reply. It seems, for now, E5 fuel is a little tricky to find, but I managed to put in 53L of E5 97 yesterday, and from a full tank it was only a similar amount of E10, so should be quite diluted by now.

Well it'll be interesting to see how difficult it is to get E5 high octane over the coming months.

It will be interesting to see if super unleaded becomes more and more difficult to find. I managed to put in 53L of Gulf Endurance (E5 97RON) although I'd have preferred Tesco, Shell or Esso's 99RON. Does anyone with an LS460 notice any difference on 99RON vs 95RON?

Does anyone know if there are tangible benefits into running RON97 or 99 fuel on the '460 vs regular 95? Or is the car not "clever" enough to make use of it? I drove 290 miles in the LS460 today (what a magnificent motorway car!!) and despite pressing on at times the economy wasn't too bad at all. Managed to put in 53 litres of RON97 (Tesco were out of Momentum 99) so that will certainly dilute the E10 95 that was in there from last Friday. I have been doing a lot of short trips in the car lately so it was a real pleasure to give it a proper run out. It is probably the best long-distance car I have ever been in or driven.

OK thanks. It's going in for service and MOT in 2 weeks so I'll get them to give that a crack. Cheers.

For a while now the resting ride height of my LS460 seems a bit hit and miss. Some days it sits lower at the back, some times a bit lower at the front than normal, some days one side is a bit higher than the other side, some days it seems perfectly normal. It doesn't "reset" itself after a drive, it doesn't make any knocks or bangs and is still smooth and comfortable over bumps. I'm not convinced it's normal (ie it shouldn't be like that) but not sure what it is? If it was the air bladders (?) wouldn't it reset after going for a drive? Also doesn't seem to matter whether the car has been sat for a number of days. Car, however, is largely used for very short trips, but will be doing 250 miles Saturday so that'll do it some good. Any thoughts? Cheers!
