Hello My car is approaching 13000 miles and I noticed that while cruising at highway speeds and I let go of the accelerator I hear a humming/ buzzing noise. I know that braking and coasting charge the hybrid battery and assume that's what I am hearing but I never noticed it before and if I did it wasn't as loud. Does anyone else hear that. Do I need to put the radio up ? Lol. Thanks in advance.
Likely the regenerative hum. Check pressing the brakes just a little bit, it should hum louder (of course when no one behind your car) Sent ?
I just started noticing something similar. It's less of a hum and more of a high pitched noise, in my case, though. It definitely happens whenever I let up on the accelerator. Not braking, and not even taking my foot fully off the pedal and sending the power gauge into the blue, just applying slightly less pressure bringing the green power bar to just above the Eco line. And while it may or may not be related, I also have started noticing a repetitive squealing noise (as if from spinning wheels) when driving a lower speeds.
