High Pitched whine around 60mph (2 Viewers)

[DWallaceMD]

Odd issue, but my 2025 GX550 Luxury makes a high pitched whine, starting at about 60mph until about 65mph, then goes away. It sounded to me like it was coming through the speakers. It only happens when I touch accelerator, gets louder the more I depress the gas, and goes away when I get out of that speed range or let off the gas. Dealer says it's normal and all GXs do that, which I suspect is not true. They say it is a drive train noise, and not coming through speakers, but they didn't have an explanation why it happens, and only at that particular speed. I don't have Luxury plus, so I don't think I have the fake engine noise? This happens in Eco, Normal, and Sport mode. Turn off your radio, drive at 60-65mph, and let me know if anyone else has this! If the dealer is correct, everyone will hear it...

I have he same issue with g550 overtrail plus . At 65 mph hear whine or whistle . If cruising with cruise control may go on off with any load . Dip in road etc . Dealer at Maintenance visit said it was turbo spooling up . Seems possible but always at that speed . Goes away after crossing 65 . Very reproducible.

Are you guys talking about the intake whistle?
