Hi Guys,

My current 6 month old 2021 nx (currently 12,500 km) is giving me quite a few problems lately.

I sometimes hear a very faint whistling noise from driver's side at about 3000 rpm when I am accelerating from 100 km/hr to 110 km/hr on the highway. When I ramp up the same ramp at 'P' or lower speeds, it doesn't happen.

While I need to eventually bring my Lexus in two weeks for them to trouble shoot a rattling noise from my dash, I am wondering if it would become a safety issue prior to that.

Thanks.

Perhaps an air leak in your driver's door window, or in the moon roof.
Next time it happens, try opening your driver's door window a couple of inches. If that doesn't make it go away, try opening your moon roof.
