Keith,
Assuming the customer is aware of the situation now, maybe you don't have to do anything else.
If the piano ever starts having issues that bother the client, they'll eventually have more reason to trust and respect you.
As far as holding the dealer or the manufacturer accountable, that can be pretty difficult as the third party not directly involved in the selling and purchasing of the piano.
What I can also share from 20+ years is that you are not alone in such experiences and the frustration that sometimes results. But if you are trying to think and act with integrity, perhaps you're also doing more than just operating with human thinking to make humans temporarily happy.
I have some locals that love to sell old used ******* uprights that look new and shiny on the outside, but are so old that they are often getting loose tuning pins. I have a customer who bought one of these, I warned him early on that I was feeling loose tuning pins (because he wanted my opinion) - and he blew it off, saying how wonderful the dealership owner was, etc, etc. Well, a couple years later and we are getting ever closer to the appointment I'll have to explain that his piano is no longer holding a tuning where tuning pins are slipping. I'll have to gently remind him once again that the piano is quite old, and this often happens. His opinion of the fabulous salesman who sold him this piano might not be quite as high at that point. I don't know. I've had other experiences like this before as well. When I was younger I pretty much spoke without caution and was punished for it. Today, I'm much more careful. Another issue I run into is elderly people who think there is a problem with their piano somewhere in the treble but who are hard of hearing and have hearing aids and things like that. That's a tricky one too.
Most of the time if you're a piano technician you care deeply both about your work - and people. Sometimes, the people that you are doing your best to help, punish you for trying to do the right thing. If you can process that and keep your kindness and your values, you'll be the better man for it.
