You really need to GIVE UP and learn to live with it.I have 1000 miles on my 2020 RTL and the whining hasn't gone away. My dealer can't seem to solve it. I hope you have better luck than me!
OK, so many things are a matter if degrees.In fact, it's a very loud and extremely irritating high pitched sound that drowns out the sound of the engine, music, your thoughts between 45 and 60 (cruising speed).
I have a 2019 RT Limited and no whinning noises. Quiet as a mouse, so unless they changed something other than body design for 2020 I can't imagine it is normal. This is my 5th CanAm only problem I ever had was a vibration between 68 and 72 mph and a belt tensioner took that away, but it was not a whinning noise.My 2015 F3S with 6,000 miles has a belt tensioner and I still get a whirling noise in 5th gear that goes away at higher rpm's. No noise in 6th gear. Might wanna try ear plugs.
I picked mine up yesterday and was blown away/annoyed by the whine. It's not just a quiet mechanical whirring, it's loud, like the whining sound coming off the wheels of a jacked-up pickup with knobby tires. It changes with speed but not with rpms, which implies that it is generated downstream from the motor/input end of the transmission. Looking forward to hearing what others find out - if my hearing isn't permanently damaged. :tango_face_sad:Anyone noticed a whirring noise, speed related it seems, on the 2020 RT Limited? May be motor or transmission, unsure. Local tech at dealer "all of them do that". Possible solution he said would putting on a tension belt idler.
