Rob, please ask your dealer to clarify why this is and report back. Paul

Andrew, Please let us know who you end up getting insurance with in the end. Paul

Totally agree with you. All my albums are arranged as I want them (in 320kps MP3) on my memory stick and I can play them through the voice commands. When I bought the car the software that was on it had broken voice indexing for the memory stick. Eventually we found a pre release version of the software that works (they never fixed it in the current releases) but the staff always said "why don't you stream your music with car play or AA?". I gave them the same reasons as you, along with not wanting to compromise the quality of the Mark Levinson system. I think a limit of 32GB is very poor, and can't see why they put in this limit. Any OS these days should be able to read much bigger filesystems than that. Why limit it? After all, even my wife's 2015 NX supports at least 64 (and it may even be a 128 in there now).

Sorry to hear this. I'm surprised that the door handles on the new RX are freezing in the same way as gen 2 NX. There have been replacements for the NX that solve this issue so I'm surprised the new design is not fitted on the newest builds (NX and RX) from factory. The range estimate on Lexus is very very conservative. You will probably have tens of miles of range left even when the predicted range shows zero. Try to have realistic expectations about software updates. Sounds like the fuel door needs an adjustment.

Good spot Colin. This is probably why, when I tried a new NX last year at some point and took the memory stick from my RX (primarily to see if the voice command indexing bug for music had been fixed between MM19 and MM21), it never worked! Progress....?!?!

Just to note that DLX has an older system (looks like 2019 ES) which is much more like the system in my 2021 RX. My RX supports 64GB (perhaps I am even using 128GB now... Can't remember, but certainly more than 32) but I never tried 256GB. There are limits to the total number of files and directories that the system can see. So, JJK, it seems MM17/MM19 (which are very similar systems - MM19 is essentially MM17 with car play/AA added) do support larger sticks. You have an MM21 system in your new ES I believe (touchscreen no track pad?). Can it be that MM21 does not support larger sticks? (It would be odd if this is the case, but then stranger things have happened with Lexus software). Sorry to sound patronising (I don't mean to..) does the multimedia manual say anything about a limit? Paul

Agree it's a nice car etc... mechanically sound, comfortable, reliable... But there is no way I could recommend a car that could be stolen in under a minute to anyone. It surprises me that the motoring press doesn't bring up this sort of issue - it's a real world problem for owners. And if the motoring press started addressing this issue then we would be more likely to see a proper fix.

For a long time in the Lexus sat nav, Lexus Edgware Road took you to the Toyota dealer about a mile down the road.

I believe this could be a fault (or dirt or water) on one of your door handles. The car can't do what you describe, so I think what is happening is that the key is in range and one of the door handle sensors is detecting a "hand" and opening the car, even when there is no hand. Perhaps dirt of water could do this, or a faulty sensor. I never looked at how the door handle "hand" sending actually works, but it's probably capacitive and hence dirt or water could perhaps trigger it. Try wiping down the handles? Paul

Hi Ricky, good news that you had the knowledge to ask for the plate to be fitted but I wonder how thefts and insurance is supposed to come down if this is not a standard fit on service or sale for all 4th gen RX. I take it from your original post that they did not even know about the CANbus plates before you brought it up? If so, that's incredible, and worrying! The car itself is excellent though, and as you say, chews up miles very easily. Paul

Hope you enjoy it. Does this mean you got the CANbus protection plate fitted? Paul

FYI 64GB works fine in MM19 systems with FAT32. You need a third party tool to format larger sticks such as http://ridgecrop.co.uk/index.htm?guiformat.htm Paul

Very interesting. When I asked to have the plate fitted to my wife's 2015 NX I was simply told the ECU was different and so the (RX) plates did not fit. I was not told the wiring loom was routed differently. I would be interested in seeing if we can obtain more certainty over this. Paul

Rayaan, If you bought your gen 5 RX from Steven Eagell, then they would have been looking at the complete deal. WBAC were just looking at the gen 4 RX in isolation, so I'm not sure this suggests that Lexus dealers are more desperate for gen 4 RX then ES any more than it suggests they are keen to sell new vehicles. Final sales figures for 2023 show almost as many ES sold as RX. This surprised me. Paul

I think series 5 was not available till Feb 23

Hi Colin, It may not be possible to port the exact same implementation from brand new vehicles onto nearly new vulnerable vehicles but this does not mean a software fix is not possible. It is clearly more work for TME/Toyota UK than making some metal plates and getting dealers to fit them and so they have gone for the low hanging fruit (RX only). This guy (who knows more about CAN security than the vast majority (all?) of forum members thinks it can be done: https://kentindell.github.io/2023/04/03/can-injection/ Perhaps for Toyota it is a simple cost benefit analysis... perhaps this will change over time? Or perhaps a proper fix simply takes a long time to write and test. Paul

The plate for the RX had already been rolled out in South Africa to prevent car jacking. It seems like it was the easiest thing just to get some more made and installed over here.

Sorry to hear this. This is the third stolen Lexus we hear about on this forum over the last few days (2 RX and one NX I believe). Can I ask if you had the CANbus protection plate fitted? I'm guessing not from your post but many owners on here will be interested to know for sure, including myself. What will you buy if it is not recovered? Paul

It was probably stolen. Paul

I think a very small subset of Lexus owners use or read this forum (and why should they - for most people it is a way of getting form A to B - they are not enthusiasts). I don't think it is reasonable to expect an owner of a pretty new vehicle to know that a security enhancement has been made to their vehicle if neither the dealer of manufacturer has alerted them to the fact.

And two more RXs... Golly.

Yeap - that was my reason too! Paul

It will be interesting to see it evolve in 2024. Paul

Agreed, Colin. I'm still surprised that they sold more gen 4 RX in 2022 (RX and RXL) than gen 5 (plug and no plug) in 2023. According to the data this was absolutely not the case when we moved from gen 3 to gen 4 (and the mk1 NX was already in the market for the RX gen 3 to gen 4 transition and the MK2 for the gen 4 to gen 5). Perhaps there were some exceptional deals to be had on MY22 RX models at that time. Cheers, Paul

I am surprised that Lexus is so "relaxed" about the ES thefts: https://media.lexus.co.uk/wp-content/uploads/sites/3/pdf/Lexus-UK-Sales-Figures-December-End-of-year-2023.pdf It seems 2023 was the best year yet for ES in the UK and is sold 1866 units, which is not far behind the new RX (sum up sales of plugin and non plugin versions) which is odd considering it's the launch year for gen 5 RX and one would expect sales to be high for a new release.
