Sounds like the dealer was testing the water to make a few bucks in the future. One experienced friend told a gullible newbie that his 2 stroke Suzuki motorcycle had bad "muffler bearings". The newbie was at the dealership the next morning, and I wish I could have seen the face of the tech when he stated his problem. Some folks will believe anything, and there's someone waiting to make money on it. Don't know if I would trust that tech you spoke with again.
Creativity is just intelligence fooling around
