Can you get a recording of your high speed noise?
I've got about 2000 miles on the new 711 motor. Haven't noticed anything at higher speeds except some really annoying high pitched chirping/ringing/squealing from the inverter when slowly applying accelerator in 35-55 mph range. It starts/stops as you pass certain pedal positions. One of these days I'll have endure a trip to a KIA dealer to test drive another Niro to see if this is considered normal. I posted some recordings over in the
UK forum.
While I no longer hear the low-speed knocking noise that started this thread, I do hear a soft pulsing sound when slowly accelerating from standstill with wheels turned. Not sure if this is early onset of the knocking noise returning or something unrelated. Time will tell but I'm also very skeptical that KIA has really solved
Thanks for your insights about this issue, wizziwig.
You've mentioned some improvement with a "new 711 motor".
How can I determine the model number of my motor.
I've got about 16K miles on my 2019 KIA Niro EV and the clicking/tapping noise has gotten noticeably worse.
