Is this normal for my 2017 Volt to generate the same noise as hard-braking when pulling the paddle for a long time before almost stopping?

I just noticed this recently, I haven't noticed it in the past 18 months or so. There's that weird noise if I pull on the paddle to slow the down the car over long distance, the same noise when friction brakes are engaged.

Stop using the regen paddle... you'll probably get better overall EV range by minimizing regen.

How do you know the when friction brakes are engaged? Except for emergency stops, the friction brakes don't engage unless you are at the very tail end of your stop - no matter whether you are pulling the regen paddle, decelerating in L, or pressing on the brake pedal.

Can you describe the noise?

There should be hardly any noise for either of those things. But the paddle and the brake pedal both engage regenerative braking, which can make a slight whining noise, so it is normal for them to both make the same sound if either one does it. My hearing is not the best, but I don't hear it unless the windows are open, radio off, fan off and at low speed. Then it is still pretty low.

If the noise is loud, it may mean you have a problem, like maybe a bad bearing.

Describe the noise. If it's a hum that decreases in volume as you slow down it's most likely a front wheel bearing.

Except a front wheel bearing will also make noise as you are accelerating. I've had my passenger side front wheel bearing replaced because of this noise. It sounded more like a low growl that went up and down in tone depending on speed.
