I received the following after complaining about the key and wheel nut issue.
I took delivery in June 23
You may find the comments about the loss of a key or a wheel interesting.
Enjoy !
I am sorry to share that your Lexus Centre, I presume is Lexus Bristol, are correct in that they would not have information or a timeline as of yet as to when the smart key and locking wheel nuts will become available.
I can only apologise for the delay in providing you with these items. It was certainly not our intention for this to be the situation but Toyota Motor Corporation in Japan have experienced semiconductor shortages which has impacted the supply of a second smart key on certain models in Lexus and Toyota.
We have started to supply our Lexus models with a second smart key but this will take a little while to fulfil. We have initiated a Customer Satisfaction Campaign (CSC) to ask owners to obtain the smart key through their Lexus Centre (it needs to be programmed by the Centre). This is being conducted in production date order so that those customers who have been waiting the longest will receive their smart key first.
This first phase is for cars manufactured between October and December 2022. Commencement of further campaigns based on the production date is to follow. I regret to advise that we have not been provided with a clear timescale. Looking at the production date of your car I would expect, realistically, that it will form part of the second or third phase of the CSC.
Please rest assured that Lexus UK are aware of the challenges and irritation that this has caused to some customers and we are doing all we can to ensure the earliest delivery of the second smart key. I can advise that should your key be mislaid we will support any work required and will provide mobility if this situation was to arise.
In relation to the locking wheel nuts. There is not a shortage of materials but they have had to be re-engineered and a new supplier appointed. This has meant that they were not available at the time of handover. I can advise that we expect the new locking wheel nuts to be available later this year and into early 2024. These will be issued to our Lexus Centre network once they are available.
I can advise that in the highly unlikely event that the wheels are stolen we would support the full cost of their replacement.
In closing, I am sorry that with this reply I have not been able to afford you a positive response but I trust I have confirmed the latest status on both issues. I do hope in all other respects your are enjoying you new NX 450h +
