You haven't got a kink in one of the hoses, have you?

Wow, that's a lot of work, especially the master cylinder. You didn't mention what I would consider easy things: pads and discs. What are they like? What are the caliper slide pins like: sliding freely?

What is the attraction of buying these parts from Rock Auto in US? Is it that they are cheaper that compatible components that are available at UK parts factors? Or is it that they are only available in the UK from Lexus dealers (at much higher prices)?

There should be no movement between the tyre and the lower spring perch. If there's a gap, however small, there's no problem with either the tyres or the suspension.

What is the service interval for plugs and front & rear transmission fluid? I'm quite relaxed about leaving the plugs longer if it is running well and fuel consumption is fine. What's the worst that can happen?

This is the thread I was referring to. Any luck yet?

I didn't buy this one from eBay in the end, I exchanged my old one with Orchard Engineering who sold me a refurbished one.

There was another thread about this issue last week, so have a look back.....

I had both your problems in my rx400h. In my car, the swimming pool in the rear footwells was the overflow from the hidden swimming pool under the boot floor. When all the floods were dry, the check hybrid problem went away. I concluded that something electronic under the boot floor didn't like being wet.

I'm surprised that problems arose while driving. I would have thought that once driving the inverter would have maintained a stable 12v for the computers to run.

I ordered the update from satnavishop on Monday. The usb stick arrived on Wednesday. The activation key arrived by email on Wednesday. I installed it on Wednesday afternoon. Full instructions were provided by satnavishop. It was an absolute doddle! No more complicated than tuning the radio or setting up Bluetooth phone connection! I would not hesitate to recommend satnavishop for future upgrades: great service and MUCH cheaper than the Lexus dealer.

Thanks for this. Did they provide good instructions about how to do the job?

I don't want this to turn into a thread that debates the merits of phone maps v Lexus maps.

Do you have a usb socket in your centre arm rest?

I went to my nearest Lexus dealer yesterday so they could examine my car and work out how to update the maps. Here is what they told me: 1) I need to buy a set of 5 discs + serial number. The part code of this item is PZ445-HD334-0Z. The discs are updated every 2 years. The latest discs were released in Apr 2022 and the next discs are due in Apr 2024. 2) In order to install the maps, a passcode or activation code is needed, and this can only be obtained by someone with the relevant computer software (ie a dealer). 3) The price for the latest discs Is £234.25, and they will install them for free. 4) They openly told me to feel free to search for another supplier of the discs (at cheaper cost), but if I managed to buy them cheaper, I'd still need to go to the dealer to get them installed. If I do this, they will charge me for half an hour of labour, which is £90, but they would want the car for a whole day. I have since searched the internet for this part code and found an interesting website here: https://www.satnavishop.co.uk/toyota-gen7-11hdd-sat-nav-map-update-europe-2023-1030-p.asp It seems to be offering everything needed, including activation code for £60. I have sent them an enquiry to check it is what I need, and how to actually install the update. Has anybody here used this website, or any other 3rd party supplier of map updates?
