Because why not? Cat-back system from GTHaus, SUS mid pipe and titanium rear boxes, videos in order - cold start valves closed, cold start valves open, cheeky rev in an acoustically pleasing car park. Maybe not everyones cup of tea, but the ear to ear grin hasn't worn off for me whenever I press the go faster pedal 😛 IMG_3886.MOV joined_video_0f729a34cc6649f59d298f2b077bfecf.MP4 IMG_4128.mov

Bad news I'm afraid. The parts of the suspension that hold air have a habit of rusting. When the rust gets bad, it rusts through to the air chamber and causes a leak. Your compressor runs and runs trying to keep the suspension inflated, but eventually it either burns out or wears out and the suspension eventually deflates and stays deflated. The suspension legs are an eye-watering amount of money to replace and unfortunately you'll have to replace at least one of them, although it's best practice to replace suspension parts in pairs. That'll be a £1000+ bill just for the parts I'm afraid. As Herbie says above, it may be time to consider replacing the air suspension with a conventional spring-based setup, because once one shock absorber has gone, the others won't be far behind and you can get a complete spring-based replacement suspension setup for less than the price of a couple of air shocks. Once you are on springs, you won't have the worry of the air shocks. Of course you could replace the air shocks, but at £600-ish a corner (plus a replacement compressor if that's died in the meantime), it's probably as much as the car is worth just to replace the suspension. It depends on how much you like the RX if you want to spend the money essentially buying the car again, or if you want to move on to something else. One of the reasons I especially sought out the spring suspension version when I bought my 2004 RX was to avoid the big bills of the air suspension.

My attitude and input as helped a lot of members over fifteen years on this forum and also contributed to a lot of solutions to problems the last person to call my car a barge is now regretting it because he had just bought a BMW and that coined the phrase "box made for #ankers". just saying.

I've never had air suspension so I'll let others with more experience answer your question, but with the eye-wateringly expensive price of spare parts for the system many people convert to traditional coils instead. Have a read of this thread:

A happy Lexus driver is a really happy man. Good news Vlad.

Hi everyone, I’m new to the forum but not to Lexus. I used to own an RX400h which I loved and always regretted selling. A Hyundai, Honda CRV, IQ and a Nissan qashqae later and I’m back! 😁 I’ve just purchased an 2016 RX450h luxury in pearl white. I’m hopefully picking it up at the weekend and I’m like a kid in a sweet shop! 👍

If Lexus Bristol said that to me, I would ask them if they are prepared to put it in writing so that I could publish it on my you-tube channel. The offside of the front screen demists just fine and I'm quite certain Lexus designed them all to clear both sides of the screen. If it worked before it went in for the recall it needs to go back to the dealer to be fixed.

Hi John It was my interpretation following a quick read through of the exclusions, however the situation has now been resolved with no charges levied. Following discussions and receiving their video to explain to me their findings which showed them to be working on the wrong side of the vehicle and totally, on the two occasions they have looked into this, they have ignored my personal findings and gone straight into stripping to wiring level. they finally today at my insistence checked the switch that I had told them was troublesome at the outset and found it to be faulty. My Lexus Extended Warranty expires at the end of the month and I shall be visiting another dealership in the future!!!!

by the time you have put the spray away any scent will be gone

Well the Hybrid battery is the same as before it just doesn't say "check Hybrid system" on the dash. I suppose it lasts longer on Battery only mode but don't do that often. Brakes made a huge difference to the car! I opted for genuine lexus discs pads and sensors and going down a hill with gentle gradual braking makes the battery charge up very quickly. Shocks were leaking slightly so i thought it be best to get them all done. I didn't have to do them but as i am ferrying my little boy around I wanted to be safe than sorry. Again Nippon did these parts far cheaper than Lexus. It cost a fair bit but i just think some things (like brakes and tyres) you just don't compromise on!

I don’t have any specific knowledge of the Lexus air suspension, but my MB CLS63 has air suspension. I had similar issues with mine and the compressor gave up the ghost. Whilst MB failed to find the fault, I did find it in the end and it was a crack in one of the airlines. The fix was a £1.90 John Guest push fit connector. I had to change the compressor as well, but in total a £127 bill for parts and a couple of hours effort. A whole lot better than the thousands I was expecting if I’d had to change out the air struts. It could be as simple as that, so inspect all exposed lines very carefully. Sent from my iPhone using Tapatalk Pro

Arms with bushes pressed out and cleaned up etc.

this is what you need https://www.halfords.com/motoring/engine-oils-fluids/grease/halfords-silicone-spray-lubricant-500ml the noise will only come back if the seal goes back to the condition it is in now.

As soon as I pick the car up I will post some pics. I can’t wait to collect it. 👍

I reckon they say "corrosion" because they can't, in most cases, find anything else of note!😁

My sincerest apologies. Having had to park in a dark location recently, I hadn't realised how much difference the reversing lights were making in other cars I've driven. More rear illumination is required in the RX400h IMHO. Will be fitting some decent brighter bulbs in due course.

Hi Kal, what exactly was the issue with the aftermarket rear section? Was it an off the shelf item or bespoke/made to measure part? When I had my rear section replaced (due to the same corrosion as yours, hardly surprising given the age) they found that my mid section couldn't cope with the wrestling and needed replacing. Which I didn't mind at the time as once it's done, the stainless repair wouldn't need looking at again. Tony Banks (Leeds) sorted mine and although it's not ghostly silent like OEM it only just makes itself heard, in-fact it now has a nice quiet burble. Have you tried TB? I'm confused by your post tho, did you buy a mid section at £1250 and now want another rear section (even tho you sourced an OEM rear from Nippon) ? If so, then what's wrong with the replacement rear ? Or are you now looking for a replacement mid section after balking at the £1250 ? Sorry to hear that the bills are mounting up tho, I guess your battery refurb was necessary and that you hadn't had a Lexus Healthcheck done in the previous 12 months? Cheers, Lee

My experience with my RX 400H (June'13 first reg.) is on the previous page. The car has been with a Lexus main dealer for 5 weeks, who have confirmed both cats. as upstream in the engine. and all the scum got was 2 feet of antique exhaust. However it's taken 5 weeks for the replacement section and associated fittings to be ordered and fitted. Unfortunately, my independent garage who I've used for 3 years, and trust, gave me an incorrect diagnosis. Lexus main dealer were seriously helpful, with impeccable comms and I got my car back today. Incidentally, they gave me a 15min health-check video, which amongst other faults, found a leaking rad. which in time could have caused an overheating engine. Leaking rads apparently not uncommon on the 400H. Claim on my insurance? Not sure yet, still thinking it through. Back to my independent for future servicing? Not sure, either, as I can't keep increasing my mortgage. Anyone else with the same problem, you might want to toss up advantages and disadvantages of a courtesy car from your insurance or Lexus customer liaison. Regarding insurance, if you have comprehensive cover, then your car has been vandalised, and can't be driven legally - they should therefore cover you.

Mine is apparently not just a barge but a slab sided one!

No problem, just some more information about the the front strut cushions/bushes below and I'll put together a list of the part number when I can but I think you have pretty much all that I replaced. As stated before, the cushions I fitted were for a Toyota Century part number 48674-40051 as listed on Amayama that ' may fit'. They do fit but are wider than the originals and I had to centre them correctly. I may be wrong but I think these cushions/bushes are harder than the originals and are definitely approx 10 mm wider (maybe it's the width of the bushes causing any issue - if there is one). My suspension was so soft before and I didn't feel anything from the road much at all but now I do. I can't compare my car with Toyota Century bushes to another car with the 'correct' bushes so I don't know if mine is 'normal' or not. Plus, I've changed the arb bushes and drop links. Maybe it takes some time for it all to bed/settle in. I just wanted to let you know about that. If I was doing it all again, now I know what's involved etc, I would bite the bullet and buy the complete arms with the correct bushes from Amayama. The original bushes were in very very tight and I called in a 'favour' to get them pressed out. I didn't know the lower arm bushes were available (I presume you mean the front lower arms) The front ARB bushes I bought from Lexus @ £20 each, Lexus said they looked ok but the ARB was moving which could have been the drop links. I fitted them anyway as I was doing other stuff. Some advice on doing the work: The strut arm bush camber bolts - one of them was an issue for me and was seized solid. If I had to do it again I wouldn't use a hydraulic puller as it bent/bulged the mounting bracket. The bracket straightened ok after but I was lucky using the puller didn't cause more damage. I discovered after that the strut arm bush mounting bracket can be removed along with the problem arm/bush to allow it to be worked on 'off the car' which would be easier. To do it on the car, I would simply cut through the camber bolt both ends (inside the bracket) with a large enough grinder and buy another camber bolt (I should have used this method) I hope that helps.

my 2006 V6 3.6ltr Honda Legend is just about bullet proof too BUT oh my, the toys and electronic gadgetry do my head in tbh ... and I can't get a comfy driving stance either for more than 15 mins the dear old barge, sorry my Mk3 Ls400 is a joy to drive wherever and whenever ................ and now almost 226k miles AND I could easily drive her all day long There's no other car i would think to just jump in after checking the engine oil and screennwash bottle and drive across Europe ..... if I'm allowed to that is with all this Brexit stuff going on Malc

Pointless on an IS 250. As Shada says, only worth bothering with on petrol or diesel turbos. Probably the best bang for your buck mod you can ever do if you have a turbo.

To add my two pence worth (as a very biased Lexus owner), Jag X-type sills are a nightmare after about 10 to 11 years, the oil leak problem on that ebay sale, is probably same as my wifes had, the new seal is £2.50, but need to take the whole darned engine out to do. I loved the engine - nice and free running, but at 140K, head gasket goes, so Jag now scrapped. On Range Rover, not quite sure why the three mates of mine who have them, keep them, they have either had teething problems from new that took over a year to get sorted and older ones, well it does not seem to matter whether you use them as a Chelsea Tractor or for Chasing Wildlife over fields, the faults keep coming. BMWs, same thing, have got many mates who own them, but none of them ever managed to keep them after 10 years, start becoming money pits. Mercs, have two mates who own Mercs, but they use them for business visits, and complain about the bills (well their company accountant does) (both own LS as the car they prefer, just do not feel quite right rocking up at a client in a 20 year old motor) Not sure if Honda do a V8, but if they do, than I expect it to be bullet proof, though thirstier than LS, previous Honda Civic we owned, the engine was bullet proof, the body work took a battering, the only thing that made us change it was a badger incident - took the front bumper out on one side, so changed to the Jag (hey-ho). Wife has just bought a 2 year old Mazda 2, not a bad car, frugal, more toys than my man cave, but will still be using the LS for our trip to Lake District next week. Being honest, when I bought my first LS it was a 11 year old Mk3, I had it for 5 years, and never did anything to it (apart form standard service), it had knocking drop links, knackered Anti-roll bushes, but it drove okay (and I suepct it needed a new ECU - as it had that horrible stalling problem), and my current motor at 19 years old and 204K on clock needs a bit of money spent on various suspension bushes. I think an LS is a bit like that Toyota Pickup they tried to destroy on Top Gear a decade or so ago, you really need to blow the darn thing up to stop it from being of any use.

Had a 1st proper ride today after wheel alignment was done on Friday and new tyres (good year 4season vector gen 2) fitted, this is such a difference! I knew new tyres should be quite but not that quite, even compared to summer tyres new ones are much much quieter, I made a good choice!

Liam. It's more to do with it being a hybrid. The engine stops and "parks" it's self in one of two positions. If the engine has not reached or overrun that position the motor in the transmission that starts the engine will move it to the correct position ready for starting. If at all in doubt have a word with the dealer. John.

Hello all,i want to know what is this blue connector called,maybe part number,beem trying to find it in the repair manual,but nothing showed up..i need to know the specific name for it so i can search on the internet for it,mine gone missing from previous owner,idk why they removed it since its very important..this thing connect all the wire at the white harness into 1 wire for ecu

Are you sure there isn't a part no on the housing itself? Magnifying glass might be needed tho

Thank you @normski2 Will do the write-up very soon. I've got quite a few videos and write-ups coming as i''ve done quite a lot of electronics mods in the past weeks

I'm thinking about getting a straight through pipe made up as well as the replacement Cat made up, so they are identical in length and fitment, that way I can run it without a Cat and not have to worry about leaving it parked, I can then swap the pipe for the Cat at MOT time. I need to find a local fabricator who would knock something up for me. My worry is that i'll get the replacement Cat fitted and the scum bags will nick that one as well.
