I have a 2014 honda Accord with ~45K miles on it. Been doing the oil changes myself thanks to your videos, but had to visit the dealership for a recall.
They did the complimentary multi-point check and highly recommended I change my: 1.break fluid / 2.transmission fluid / 3.power steering fluid. They explained they're all recommended after 30K/3years....
Funny thing is that by looking it up I realized my accord does NOT even have power steering fluid, it became all electric somehow. Which makes me believe they didn't even bother checking, they just recommended it as a way of fishing money, which is deplorable.
I would really like to know what you think about changing the brake fluids and the transmission fluid at this point, knowing I have no complaints whatsoever with the car. But just like you I'm planing to have my cars run as long as possible without the pain of being ripped off.
Thanks a lot!
