Really you need to check the same things as the RX300. Rust, especially underneath, water ingress into the boot well (which is especially important to check on the 400h as it can get into the hybrid battery). Timing belt changed. Check for suspension/steering play/noises as it's a big heavy car that puts stress on those components.

The smaller one is fine for any Lexus hybrid or EV because the 12v battery isn't used to start the petrol engine and therefore it won't draw much power. You have want a larger one to support other petrol/diesel cars you might own or help out other people's cars.

Correct. The only issue might be MOT issues if the primary cats are hot enough but the tester would probably just run the engine for a bit longer and retest.

Make sure you aren't in Eco drive mode as that reduces the energy the AC system will use and won't get as cold as you expect.

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 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.

Two weeks shouldn’t be a problem on a healthy battery, although it would have discharged the battery to a point where it would start to damage it and therefore the capacity may have been diminished. Three weeks is when you start to run into problems.

Yes, I'm sure all Lexus UK sold vehicles have a Cat 1 alarm/immobiliser as standard (despite gaps in the model information you can find online listing Thatcham approved devices). It's really down to your insurance company to tell you otherwise, they are the ones with the information on what is fitted as standard, not the owner 😞

Check the manual but it is possibly down to the new speed limit regulations that all new models have to conform with. Whilst you can manually disable the function it must reset back to default on every restart.

When I purchased a used yellow car - “these are very rare, we can’t give you any discount” When I sold it - “there isn’t much demand for this colour hence a lower trade in price compared to book value”

2015 onwards ideally. It is rare in the UK but older engines can have excessive oil consumption due to clogging of the piston rings - parts were redesigned in 2015.

Yes, same on all Toyota/Lexus hybrids unfortunately.

The LBX isn't vulnerable to the attacks currently used. Lexus should have a solution for the UX, we just don't know when yet (they have already missed their initial end April deadline) or how much an owner may need to contribute.

I'm sure Lexus will be happy to resolve the issue but it would be chargeable - tell your repairer to either fix the issue or you will be sending them a bill.

Only if it interferes with the normal operation of the vehicle or the installation is of poor quality - for both scenarios your recourse would be with the installer and not Lexus.

The company performing the repair didn't follow the correct replacement procedure which states a recalibration is required and therefore the guide lines disappeared. The guide lines wouldn't have disappeared if the vehicle wasn't involved in an accident and had parts replaced - therefore it isn't a warranty issue.

Warranty doesn't cover a third party's failed work.

Luckily it only has two!

I assume your car has HID headlight if it has washers. It would therefore be an MOT failure if your washers aren’t working.

2017/10 refers to the manufacturing date. When was your car registered, if it was before Dec 2017 it is unlikely to be affected.

They did but they have now removed that reference and now don't give a specific timeframe.

Lexus offer their old extended warranty for vehicles between 10 and 15 years old.

Exhaust leak then upstream sensor then injectors should be inspected first in that order before considering the cat itself is at fault. Unlikely to be something common such as the MAF sensor if only one bank affected.

A new vehicle comes with them. If you purchase new pads or even a new calliper you would be expected to reuse the existing ones. I wouldn't expect a Toyota/Lexus dealer to use copper grease, they have specific service bulletins that mention the correct grease and the amount to use.

Personally I'd go AWD for the extra performance. If that isn't a factor for you there are other reasons: I've not driven the FWD NX but 240 bhp just through the front wheels means it will struggle for grip on occasions if you put your foot hard down, and I suspect you will also get some torque steer. Moving 50 bhp to the rear will help here. The AWD helps with traction and stability, it isn't just about acceleration. The AWD system isn't a mechanical one with a centre diff so keeping all tyres at a consistent thread depth isn't critical - you can just replace front/rear tyres. VED isn't based on emissions so there isn't a penalty here. With the previous generation NX the FWD model was just an entry level grade so hardly any were sold. With the current generation you can get FWD across multiple grades but it still sells in very small numbers - less than 1 in 20. I suspect if you order one it will definitely be built to order with a long waiting time, whereas popular options are sometimes pre-ordered by Lexus GB to reduce wait times. Given the lack of popularity I'd also question resale value on the FWD models - although if you are purchasing on PCP or leasing this isn't a concern.
