Rear Disc Squeaking in Yamaha X-max 250 Tech Max

I am having a problem with my X-max 250 Tech Max vehicle, which I purchased brand new from a Yamaha authorized dealer on February 5, 2023. While the bike is in normal motion and two people get on it, the rear disc makes a squeaking sound as if it is rubbing against the pads or somewhere else. It's not very loud, but it's audible and it bothers me a lot. Today I took my vehicle to the authorized service, and they told me that there was a chronic malfunction in these engines. A few customers had come with this problem before; they changed the engine lining and disc, but they could not find a solution, and after 2000 km, this sound would disappear by itself. Now I'm asking, is it normal to have this problem in the new X-max 250 Tech Max 2023 model crate engine released by the great Yamaha?
