I service my car (2015 CT 200h) at a Toyota dealership as there isn't a Lexus nearby. The latest list of recommended services came back with a "hybrid battery service" , when I pushed for info on this service they said it's cleaning the fan. I've not had any issues and only have 56,600km on the car. Work from home, no kids/super rare to have anyone in the back seat, and my dog doesn't shed a lot (bulldog) and is very rarely in the car. From what I can find this fn cleaning seems to be everywhere online related to the Prius, and the one Lexus document I found from 2014 recommended it for severe use vehicles only (taxis etc). Is this a service scam, or have others required this? The cost seemed ridiculous... Thanks!
