I had my RX400h serviced a couple of weeks ago, when I picked it up the dealer told me that I needed to book it in for recall work. The work was done this week and involved a new inverter being fitted. The inverter was checked under a recall last year and I was told no action was required, the inverter was ok. I presume a further problem has developed needing the part to be changed. I did not have a recall letter through the post, as I said, dealer informed me on collection from a service.
