‼️This is shocking ‼️Hyundai kona electric engine fault!

This vehicle had a bad droning when decelerating, which was diagnosed as the regenerative braking system.
This is all built into the reduction gear on the side of the traction motor. ( a bit like a combustion engine with the gear box on the side).
Little more detail regeneration braking is when a hybrid or electric vehicle is driven and when the driver takes their foot off the accelerator and coasts/rolls and brakes the reduction gear converts that into electric energy and deposits it back into the battery.

Thanks for showing bro !

[@owensautotips]

No problem buddy, hope you enjoyed it! Plenty more on the channel :)

My 2020 Kona Electric Ultimate with 29000 miles is in the shop right now for this. I am renting a 2023 Kona Electric with 3500 miles. Same generation car. Only sound heard is faint tire noise and VESS. The difference is striking. The sound this problem is making actually occurs all the time it is just louder at certain times like in regen to a stop.

[@owensautotips]

Hopefully you get it sorted soon 💪

2019-2020 Kona EV and perhaps Kia Niro as well, premature motor and gear transfer bearing wear. Also reduction gear case premature wear due to oil contamination.

[@owensautotips]

Haven’t had the time to fully investigate yet, but I will look out for this thanks :)

​@@owensautotipswait! Does this mean you've just voided thier 8 year drivetrain warranty?

[@owensautotips]

@@simonhenry7867 how would I void it? When I work for Hyundai and just replaced it under warranty

[@jrodrims27]

Gas cars have ENGINES, electric cars use MOTORS. Just sayin, first people would erroneously call engines motors and now motors engines...whatever.

[@owensautotips]

Engine - a machine with moving parts that converts power into motion, motor or engine is the correct terminology

[@thomasadmiral3401]

I don't want to get involved, but you could have shown a test before the repair to see how noisy it was.

[@owensautotips]

Unless I’m strapping my camera into the engine bay whilst driving that wouldn’t happen sorry

[@owensautotips]

But the part in the video where I’m spinning the traction motor with the drill is the noise. Only way to show it

[@Cin4n]

Hi! Swapping from 39kwh to 64kwh battery, do i need relearning the bms to car Ecu? Or?

[@owensautotips]

Yes

[@Herlongian]

There is a TSB for this for both the Kona and the Niro. The gear reduction unit and the motor needs replacement.

[@owensautotips]

so the tsb states to test both which we did, as i work for hyundai.. in this case only the traction motor was at fault, although newer models like the ioniq 5 and 6 the traction motor and reduction gear are all one unit and cant be separated which would require a whole unit

[@Herlongian]

@@owensautotips Do you disassemble once and test both GRU and motor or does it require multiple disassembly /reassembly?

[@owensautotips]

We remove the whole motor and reduction gear all at once. Separate them and test them individually

[@benellis7427]

I’ve got these symptoms on an Ioniq. Dealer has bad hearing apparently.

[@NeluCebotari]

Hey, can you tell me where I can find more info about this TSB? The service refuses to fix my Kona under warranty, maybe this can help

[@jan9574]

Thanks. Nice explain.. Whats your to meet your garage. ?

[@owensautotips]

Sorry I don’t give out my works location on social media

[@mahbubur635493]

Give me your email address to contact then please so I can contact you and ask for further suggestions or helps

[@jrodrims27]

To date, this "shocking" problem has left nobody stranded anywhere at any time. It is for the most part just an annoying faint noise which is barely noticeable if you listen for it. It doesn't affect how the car drives, feels or accelerates or cruises, just a faint little noise at low speeds but IT IS annoying for a fairly new car. A little normal "engine" noise and exhaust drone like a gas car would surely drown it out of existence. HA!!

[@owensautotips]

The fact your taking it way out of context is insane. I’ve worked on a few and this wasn’t a faint noise it was a constant drum. Worse than a wheel bearing. But hey your the technician right 👍🏻 please keep comments on one post please

[@owensautotips]

And if you want to get really technical it’s a ‘traction motor and a reduction gear’ :)

[@Peppermint1]

You wait until your car gets stranded to have it fixed ?
