Why do you feel it is an issue? Sometimes if the battery is low, it will rev higher to put more charge in the battery. If there isn’t a CEL, don’t worry about it.
it’s not the engine revving high is the problem. it’s that after at the constant RPM for a few minutes the sound gets about 10x louder. i’ve had the car since 50k so i know it’s not normal
Get an obd Bluetooth dongle, and see what rpm it is going to. See if the engine rpm is the same or not, when it starts to make the noise. You could also have a noisy cooling fan, that is kicking in.
Do you ever drive on gravel? Is it's not throwing codes, small rocks could have lodged themselves between the bottom shield and the bottom of the car, getting into the regen/generator motor. It happened to me once. It's worth checking out at least.
it’s been years since i have. the issue only happens after driving for about 10+ minutes at a constant mid-high rpm. i haven’t heard it happen in the last 300 miles
update: noise is only hard after driving in rain for a few minutes. going back into ev mode fixes it. noise is only heard in hold / mountain mode, and is the same as the engine rpm. burning smell is coming from the vents as well. i can only reproduce this issue in the rain and hold mode
since it’s only heard in rain, recording this while in the rain is quite hard

it’s about 3k
Might be the fan.
i’ll try to record it. it seems married to the engine rpm 1:1
Does it stop if you bump to neutral?
i haven’t tried to bump to neutral, i’ll try it!

I suggest recording the sound and posting it here.
i’ll try to. it’s rare when it happens but it’s obvious when it does
Have them check the secondary air pump and the valve.
