2024 Cfmoto 450NK

The rear master cylinder brake. 1st: incident I had the bike for 1 day and when i took it out to test it, no rear brake. Was told rear master cylinder. So right off the bat the rear master cylinder was bad to begin with. 2nd: incident.(DATE OF EVENT: April 8th, 2026 but didn't get picked up for repair by dealership until April 17th, 2026) the replacement part they put on to replace the original went bad when it worked perfectly fine putting it up for the winter. Bike was stored inside the house not being used! When it went bad. How can a rear master cylinder go bad just sitting there out of the weather elements?? I don't trust any replacement parts they will get. They have had my bike for 2 almost 3 weeks now. Looking at many many forums, many others are having the same exact issue I am with their bikes being held for 5weeks or more. One gentlemen said he bought in 2024 a 450nk for his wife and an 800nk BOTH had the same issue twice. WHY is there no recall for this problem? Does someone have to die for changes to happen?
