As stated in the footer of every post I make, I have a 2022 MYLR which was manufactured Dec 2021
I have also owned an early 90's MR2 which tended to suffer from a resonant groan at 67 mph - I led a group of enthusiasts with stethescopes and girlfriends to isolate it to a bit of trim in the passenger wheel well liner that could be screwed or glued down to great satisfaction.
I owned an early 2003 SL500 which was infamous for coffee-grinding noises at startup from the SBC braking pump that could be minimized with a bit of foam insulation.
I had a late model GS450H who's otherwise delightfully silent cabin was disturbed by wind noise from the sunroof area. With fellow enthusiasts we located an updated sunroof gasket part that was a fraction of a millimeter larger, we even located the oem source for it at $18, and crafted clever instructions on how to replace it without dismantling the entire roof area.
At no time did my enthusiasm for these cars cause me to rant about it or make a protest website - I worked with fellow enthusiasts to LEARN and cure the issue. Calmly. Intelligently.
A constant hum should be trivial to locate - no girlfriend hanging out the passenger window with a stethescope required
