This is very much a can of worms and has been discussed long and hard. You can get alternatives but it can be a bit of a minefield, so my best advice is to order from Lexus Parts Direct who are an actual Lexus main dealer but they sell stuff much cheaper than other dealers. That link will take you directly to it.

Well, yes, but why would you do that? My key fob (on both 2013 and 2018 RXs) has three buttons - top one is 'Lock', middle one is 'Unlock' and bottom one is for the tailgate. Press the middle one momentarily to unlock the whole car and then press and hold the bottom one to open the tailgate. EDIT - just realised that I may have misunderstood you. I thought you meant unlock the car as you're walking to it and then press the tailgate button on the tailgate once you got there

I'd stake a month's salary on it being the 12V battery dying. The alarm will (should) have it's own back-up battery and as the main 12V battery is low, the alarm back-up battery is also going low, which in turn activates the alarm because it thinks it's being tampered with. When you get a new battery you really need to try to use the car more but if that's not ractical, two alternatives are to connect a trickle charger such as the CTEK MX5 or to run the car in READY mode, whilst in P, for 60 minutes a week.

Just get cameras fitted and you'll be good to go Malcolm

And here are some of the ridiculous dashcam scams coming out of Russia. They may look stupid, silly, even some of them funny, but if the dashcam wasn't present, I wonder how many of these scammers would get away with it?

@Harrier Man You ask why have a dashcam and we reply asking why not? Maybe this will help persuade you - and there are many, many more examples on YouTube:

No, the car has to be unlocked first.

Can of Worms.....OPENED! Not really sure if this should be in the RX forum as it may only be the RX that uses this size of tyres, but anyway, just seen the following question posed in the Lexus Owners Club UK Facebook Group: I've heard that some RX owners have swapped from 235/55/20 to 255/50/20 because of the vastly superior choice of rubber available. Has anyone done this, and what have you noticed real-world in terms of handling and MPG? I note that both my favourites, Michelin Cross Climate and Goodyear Vector 4Seasons, are available in the 255/50/20 size, so what are the ramifications of changing to that size on a 2018 RX450h?

This is from the RX400h workshop manual Jack:

As always, word of mouth recommendation is the best, but failing that just Google for car detailers in your area and look at reviews. This may be too far for you (having said that, we bought our car at Lexus Teesside and it's a lovely two-hour run) but this is a company here in Preston that scores 4.8 out of 5 stars over 22 reviews. There's also Sunnybank Car Detailing (no website) who score 5.0 out of 5 stars over 10 reviews.

Personally I would cancel that and go to a proper detailer. Detailing, ceramic coatings and so on are a specialised skill on their own. Horses for courses as the saying goes.

Absolutely. Of course, it does rely on people knowing how to use aircon properly in the first place and I completely agree with Linas there. It should really never be turned off because again, as Linas says, it's the circulation of lubricating oil that keeps the rubber seals supple and prevents them from drying out, therefore preventing an escape of gas and oil. If that one condition is met then there is absolutely no need whatsoever to mess about with having the aircon "serviced". The clue is really in the name as it's all one big (air)con I've had cars for 10 years that have been as icy cold as the day I bought them and never had a service done on the AC. Only just last week, in a different topic, @steve2006 said that he'd owned his Celsior for 26 years and never had it serviced and it was still as cold as ever when he sold it.

I'm being pedantic, I know, but no, it does not need to be serviced every two years. The refrigerant and lubricating oil is kept within a sealed system. Neither the gas nor the oil wear out, degrade, or undergo any changes whatsoever, so that's that part of the system covered. As for the mechanics of it all, I doubt any advanced warning of seizure would be visible, so that's that part of the system dealt with. Any escape of gas or lubricant would be flagged up by the aircon not getting as cold as it used to, but that would be classed as a fault that needs to be investigated ny the use of vacuum pumps and dyes. There is absolutely no need to waste money on "routine servicing" of the aircon system. Sorry, rant over - just one of my pet hates

Paul beat me to it, sort of. I was going to say that someone on these forums (can't remember who) took the car out of the showroom and then spent the best part of four days I think it was, machine polishing, waxing, and so on - so I think the answer is, do it whenever you want.

Often some very interesting stuff in El Reg

As Royoftherovers says, Relax doesn't cover multimedia anyway. However, even if it did, the usual rule of thumb is that you may invalidate the warranty on whichever thing it is you're working on, but not for the whole car. For instance, modifying the lights may invalidate any lighting claims but it wouldn't invalidate a claim on the brakes or the cooling system etc.

I doubt anyone will pay to have it shipped from the USA - this is a UK forum. Plus, if you're serious about selling it anywhere, you need MUCH more detail and lots of photos.

Glad you got it sorted Stew I'm not an audiophile either so I wouldn't go out of my way to replace it with some super-dooper unit that costs a fortune. I would say any speaker that has the same impedance and power rating and is the correct physical size to fit, would do me.

You could try http://lexuspartsdirect.co.uk They're a main dealer but sell stuff out a lot less than other dealers.

Beautiful car Shahpor, enjoy!

You could indeed, and many people often do. Sometimes it's unavoidable but that's not the case with dashcams so I stand by my point.

I would sincerely hope not. As it stands I have a choice of which camera(s) to fit and if they ever go faulty I can either replace like-for-like or take the opportunity to change brands, all at a reasonable cost. Imagine the cost of replacing a Lexus camera when it goes faulty, not to mention that you're stuck with lack of choice.

I would give up on ever using it. The Lexus voice recognition is and always has been, abysmal, and usually goes something like this: Me: "Call home" Car: "Dialling 837. If this is incorrect blah, blah" Me: "Dial home" Car: "Dialling 3492. If this is incorrect...." Me: "Dial 01632 753951" Car: "Dialling 58. If this is incorrect....." Me: "AARRGGHH!!!"

It's a stipulation because they want to make money. A significant loss of gas would result in the aircon not being as cold as it should, which is something easily discovered by a person and much earlier too.

Maybe it's because I never switch the aircon (and now the superior climate control) off at all. Summer, winter, 365 days per year, my AC or CC is/has always been on, so the seals have never dried out and I've never lost any gas.
