Had a flat earlier but was from a staple I picked up, I just had a 565mile trip this past weekend, no troubles, took the windshield off and had no noise. :) I have heard the whistle ppl have talked about, not sure where its coming from, I hear the lifters too at certain speeds which can sound like a whistle, mines going in tonight on the throttle hanging up problem, service manager said “what am I suppose to do”, what a reply coming from a dealer, I’m close to telling him what he can do! Not much hope on them fixing it at all, but the balls rolling any way, there’s another noise that my wife hears sitting on the back and I have heard it too, sounds something like what a chain and sprocket sound like that are wearing out but we know that’s not it. :) Sounds like the same speed the belts turning at so it might be that guard hitting around the belt or the disks but that’s just a thought also. It will take time to work them out at least. Good luck with the tire
