Mine was done on Friday at Lexus Teesside, was given an IS300H as a loan for the day. I took half a day of work so I could take it for a proper spin :)
Also got the complimentary fuel as per other's here and was told that it was to compensate for the inconvenience, so it's clearly Lexus policy on the recall.
I asked if both the washer and sensor had been replaced and was told that both were changed. They took all day and in fact I had to chase them to find out if my car was ready to collect. They offered to let me keep the loan car overnight but I had an early start the next morning so I declined.
As expected, I also got a Vehicle Health Check report (but no video...)
All green, apart from tyres (all of which have 4mm or more tread so I'm not worried just yet) and brakes (front disks lipped, rear pads on 4mm/3mm) but there was a comment of 'NSF Bottom Ball joint leaking grease' so I will have to get that looked at.
