I'm not gonna worry about preventing anything until the warranty is up. I'll keep going back to the dealer every time I have an issue, they don't mind it's how they make their money (they bill Ducati for warranty work performed.)
Yes, but DUCATI actually pays them peanuts compared to the normal hourly rate they charge through the workshop.
Then you have to factor in the paperwork they have to do to process the warranty, which they don't get paid for.
