I just called my dealer for an update. Mine is still a non-covered order, last update was 23rd September, this has now moved to 7th October and I have no faith in that date either.
Re. the MY23 changes they did confirm that the infotainment will be updated, with delete of the touchpad and DVD. They couldn't provide anything firm but said that they have been told that cars being produced from the start of August will be MY23.
I told my dealer that I would raise this with Lexus UK and have just filled in the online form as I couldn't find a phone number. I don't blame the dealer in any way, they are telling me what they know, but it just isn't good enough.
I sympathise with the logistical challenges but have absolutely no tolerance for the abysmal communications and lack of information, especially regarding the MY23 updates. They either don't care, lack the resources to cope, or are intentionally not communicating as a strategy. None of these sit very well with me.
