I have one 500 C/M body, in regular use, that hasn't been serviced since i got it new 30 years ago, i.e. never. Never a problem either.
I certainly agree with Q.G. on this.
I've been shooting Hasselblads for over 40 years, and I repair them.
The equipment is built like a tank. By far the most rugged design I've ever seen among all the camera brands that I've serviced, and I only work on pro-grade gear.
All of my Hasselblad equipment except the CFV-39 was purchased used, because I can't afford the new stuff. I've never had a problem with any of it. I must confess that I never CLA any of the gear, although I should. I have serviced a couple of shutters, but that was years ago.
Anyhow, if you hear somebody griping about Hasselblad being unreliable, close your ears.
I can't address the quality of the new H series since I've never used or serviced any of it.
