2019 Kona EV Motor Noise Issue

Good to hear!

 

I looked up this part for the 2019 and it says that the 701 and 702 versions "don't fit" that model year. But every replacement on this thread has been the 702 model including 2019s. Maybe the parts website is incorrect? I did notice that the 702, while newer, is 2 or 3 thousand dollars LESS than the recommended 2019 part...the ones that have failed. Hmm.

 

That's great, after my traction motor assembly was replaced the difference is night and day better. The replacement only took about 5 hours vs 2 days to replace the reduction gear. I did have to wait 3 months for the parts to arrive though.

 

I'd mentioned before about how constant exposure to the motor sounds may have made me a bit deaf to the increasing noise. I got a loaner gas Kona for a two hour drive from the dealer and back. This is the first different car I've driven in two years. I immediately noticed how quiet the gas Kona seemed (not a good sign). When I picked up my car today and drove it I could not even comprehend the volume of the racket. It was astonishing how I failed to notice it before.

 

Tomorrow I'm taking my Kona to dealearshop for electric motor swap
I hope to get rid of motor noise
See you at the end of the week

 

Good luck with it. Where are you located?

 

Romania

 

I had my traction motor replaced last week. All back to normal! It did take about four months to get the parts though.

 

That's good to hear. I figured three to four months wait would be likely for mine. Fingers crossed, breath definitely not holding.

 

Update after changing the electric motor

There is a little bit silencer but the mettalic noise when braking under 15km/h it's still there

 

Do you have any idea as to whether the metallic sound is related to brakes or regen? Because if it's brakes then some servicing or aggressive braking might scour the pads and clean them, eliminating the metallic noises.

 

No because the mettalic noise its also at low speeds when moving from a stop

 

This sounds like the brake clunk that is related to the clips and pad size?

 

It sounds like this

 

Got the call! Parts are in and I've got an appointment for motor unit and drive unit replacement on May 25th. I'm told it should be a one day overnight stay and I'll be getting a loaner. Back in February I guessed parts would arrive around May 24th long weekend. Expectations met. Here's hoping it works! By the way, my Service Tech mentioned that there IS an official bulletin about the drive unit noises from Hyundai with recommended fixes. So any dealership should have guidance available to them should your car manifest these issues.

 

TSB now available (31 pages!) for this issue - It's only taken three years!
