Just in case you don’t know…. Lexus is owned by Toyota (it’s their “luxury” brand). The LBX is based on the Toyota Yaris/Yaris Cross - which has exactly the same issue with 12v batteries draining. Personally, I would probably agree to the dealer replacing the 12v battery but get in writing you can reject the car later if the same issue happens again. I agree with others that whatever you do, keep the rejection separate from any other purchase.

It would, as I understand it, be treated as a recall (so FOC) with a nominal sum for fitting (a bit like the plates) but as a recall is technically for safety reasons and this isn't safety related, there's no statutory pressure on them to speed things up. I agree about the NDA. I guess they're late with their planned roll out which seems to indicate either procurement or design is late. The dealer announcement was meant to be from April 2024 and we're a month past that now.

could well last the next owner FOREVER methinks Well Done ..... zillions of hours and £££££ spent and makes your initial £400 " investment " wizadry and wondrous .............. Hope it all sells well for you Best wshes Malc

Por lo que se ve nadie porque no ha contestado nadie .pero es muy buena pregunta

Take it you didn't purchase it as its still listed?

Yes, mine has a sunroof. the reason they didn't fit the full panoramic roof was weight. Apparently it was a shipping restriction. Cars could be spec'd with panoramic room (domestic market) and active stabilisers (which mine has got) but it took the car over the shipping weight limit based on contracted shipping costs. That restriction's now lifted so ironically you could spec both now and get it. Not a technical reason which I initially thought it might have been.

Bob, with regards to regen, I've been using regen from day one but haven't really looked into it to see what -if any- difference it makes. I think it must improve things at slower speed because you can see the energy going back into the battery. I only use it around town now because I have seen a lot of You Tube videos where people suggest it is better to coast if you can because as they say it uses more energy to get back up to speed if you use it to slow down from higher speeds. As I say, I don't really know but I do use it around town. Perhaps others on here will have a better view of this.

Insurer was NFU Mutual in the end. Not the cheapest but the best cover and best claims handling service overall. One thing I liked was there's not year on year hikes as no shareholders to keep affluent.

P0420 is often caused by an exhaust air leak so I would make sure the sensor is correctly seated and torqued down correctly and that you didn't flex the exhaust and put a hole in it somewhere when you removed/installed the old/new sensor.

I have reluctantly decided to sell my car, which has kept me busy, on and off, over the last four years. My trials, tribulations and triumphs are chronicled in the following topics: Below is a draft of the advertisement I shall shortly be placing on Car & Classic's website, but I thought I would give club members a heads up, in case anyone is interested. If so, please send me a PM. I live in Milton Keynes. "1996 Lexus LS400 (UCF20R) - N808 VRP 90,423 miles Onyx black (202) with Dark Metallic Grey (UCA31) cladding & bumpers Light grey interior 3 owners, including me. The first owner, a friend of mine, owned it for over 20 years MoT expiry date 20/04/2025 I bought this car in 2020 from a friend of the original owner as a non-runner, which proved to be a faulty alarm immobiliser system. The mileage then was 79,844. Since then I have done a lot of work to bring it up to its present condition, culminating in a full respray, and it always draws favourable comments. There is a mostly complete service history, apart from between 2015 and 2020, when the second owner owned the car. The work I have done on the car includes, but is not limited to, the following: ENGINE & DRIVETRAIN Timing belt, auxiliary belt, idlers and water pump replaced. Oil, air and cabin filters replaced. Engine oil, power steering fluid and differential oil replaced. Spark plugs changed. BRAKES, STEERING & SUSPENSION Front and rear brakes pipes repaired or replaced as necessary. All four calipers overhauled, with new seals. All four flexible hoses and brake discs replaced. Rear brake pads and sensors replaced. Parking brake cables and shoes replaced. Four new tyres fitted. Rear shock absorbers, steering tie rods ends and front brake dust shields replaced. INTERIOR All leather upholstery cleaned and restored. ELECTRICAL New battery fitted. Instrument cluster and climate control panel replaced. Stereo replaced with a Pioneer MVH-A200VBT unit so now has AUX and USB inputs. It also is connected to the reversing camera I fitted. Aerial mast replaced. BODYWORK There were marks and blemishes (but no rust, thankfully) on every panel, so I removed the bumpers, cladding, door windows and handles and embarked on a full respray in the original Onyx Black. All badges have been re-plated in 24kt gold. I also repainted the wheels. The bonnet struts have been replaced. The car now looks very smart and rides well and the stereo is fantastic. I will do an oil service before sale. If you check the MoT history you will see the tester commented on the presence of rust on the rear suspension. I have therefore removed all the loose rust, applied rust inhibitor and then sealed the entire suspension with lanolin wax. Obviously I have replaced the faulty number plate bulb. I should point out that the seat heaters unfortunately do not work, and apparently haven’t for many years. This seems to be a fairly common problem. This is by far the most comfortable car I have owned in my 60 years of driving, so I shall miss it, but now it’s time for someone else to enjoy it." And here a a few photographs:

….haha, Malcolm - your fun! ! 😃

I tried to go back to my original ECU and the 12v battery didn't last long enough for the 30 minute initialisation, so couldn't revert. Since running on the replacement I'm getting good old P0A80 (replace hybrid battery pack as current, pending & history) and the standard 'check hybrid/vsc/ecb' messages. Techstream shows the voltage blocks looking pretty good (all around 16.5/16.6v except for block 4 which is at 15.36, so slightly lower than the rest. Could be that the battery needs another coincidental rebuild (as it tends to need a rebuild every yr or so with a cell ) or it could be that now I have a completely functioning ECU its spotting issues the original (Degraded) one missed.

I suspect it has taken some impact damage from a stone and therefore you are somewhat lucky that it is being covered under warranty. There is certainly no common issue with the UX's AC system.

Awesome. Sounds like a good weekend DIY job. I agree that the original toyota pads are super dusty but wonder if its intentional to prolong life of the discs. My major gripe with the originals is squealing. Disappointing on a premium car. Despite having the shims etc my fronts squeal when stopping at low speeds. Do these EBC brakes fix that? Is there no squeaking/squealing?

With the road tax thing in mind, my choice would be the GS300 (V6). One of the best cars I ever owned from a comfort and driving POV. Whilst not as peppy as the 450h it's still quicker than an RX450h, economical on a longer run (we used to get mid 40's mpg on motorway trips from our) and every bit as luxurious. I always considered is as an "LS-Fastback"! Trouble of course is that now, finding a good example is getting tougher. They exist but all will need some sort of work, so you may be better off sticking with what you have and investing in a hybrid health check from elsewhere or paying Lexus to do it. It doesn't cost much or take long and there are independents that supply and fit new batteries. Contrary to popular believe, it's actually quite a simple system (service wise) and batteries not horrendously expensive, but plan to spend around £1500-£2K from and independent. Inverters can be serviced and are also pretty simple affairs with few parts in them which aren't short lived. The most important thing for inverters for lifespan is keeping them well ventilated. If a few £K seems steep, think of the life of newer LiIon battery packs. A typical 70KW pack like the RZ uses is currently around £5.5K-£6K to renew and has an estimated lifespan based on nr of typical recharge cycles of around 6 to 10 years! The hybrid system is the less expensive service item providing motors and inverter are healthy.

Swapped out my K&N panel for an OEM style pleated filter. I prefer the higher dirt catching efficiency of the OEM style. Let us know if you notice any performance gain.

The rear door trim comes off without removing the interior door covers, but the front trim only comes off once the sail panel behind the mirror is removed. And to get that off it seems like it is necessary to remove the interior door cover 😞 I'm wanting to do the drivers door (RHD) but really don't want to go through the hassle of removing the inside panel. If you have figured out a way of getting the front door belt trim off without removing the panel I'll be the first to say thanks 😄 Cheers...

SC430..what an excellent example of reliability 👏🏻👏🏻

hello, where can i find driveshaft for lexus rx450h 2009

It’s interesting to study this and to note the law allows EMERGENCY USE of different sized wheels as a spare up to 50mph but as EMERGENCY USE ONLY could get many owners out of a difficult “ hole “ in that hopefully rare event But it has to clearly fit the studs etc 🤔 Malc

Worth checking track rod bushings. They tend to split due to weight of vehicle from surprisingly low mileages (my first one was done at 30K miles and another is due shortly at 45K miles). Check underside, especially rear sub-frame for corrosion. Many aren't treated and really ought to be. A wire brushing and clean up followed by liberally spraying in lanoguard is a good idea (goes for all the chassis metalwork). Rubber seals around door openings can crack or perish with age unless kept clean. Best cleaned with mild soapy water then using a finger, run some silicon grease around them all which keeps them nice and supple. Check water pump for leaks as this could be an issue on earlier ones, and check variable valve (timing) oil feed pipe as some can weep from the joint. Other than that, very little goes wrong. It's one of the most reliable engines going. Lexus can offer a hybrid health check for a minimal sum or it's included if you have the car serviced with them. Check tyre wear for uneven wear which may point to a wheel alignment issue as sometimes owners don't bother with periodic alignment checks and adjustments. Check all electrics work properly and front/rear lights for signs of condensation. Great cars, hope you enjoy yours.

MG’s are great value - sounds like it ticks all the boxes for you! Hopefully more affordable on insurance too.

That's very impressive Ray. My '07 Lexbus has 12 out of 15 green MoTs, orange advisories on 3 pre-2017, all tyre related. Bought it privately in Dec '22 and am very happy. Cambelt & water pump replaced at 66k, new 12v battery @ 71k, now just tipped 89k and I'm wondering about spark plug replacement ... any thoughts?

I am getting the MA1 to work, its just a bit of a faff having to go through the rigmarole each time I start the car.; I'll persevere for the time being, in the hope of an update from Lexus to wireless AA.

Thought I was the only person to think 'rubbish badge on the bonnet'... Perhaps Lexus deemed a proper badge too expensive on the 'cheap' Lexus? All the more disappointing given the lack of a badge on the rear, in favour of the 'on trend' script (which is also rubbish, IMO). OK, not important in the grand scheme of things, but, meh!
