Strange noice when driving on cold EV and when releasing gas pedal
I have Kia Niro 2017 in "L" version. Some time ago I observed strange sound of wiping (scratching) when driving on a cold electric motor and when releasing gas pedals. When I drive a bit on the EV after a few minutes, I can not hear it but until then I hear this sound more when I go down the hill and suddenly release the gas pedal and then I hear "trr..trr..tr ..".
The Kia Service did the diagnostics and they did not find anything. Unfortunately, during the tests they didn't hear this sound clearly or at all.
Have you heard something like that with cold electric engine and when you release the gas pedal?
