A brief update - so the dealer in Sofia changed my traction motor with the 712. They did it in exactly two weeks, kept their schedule to the minute. I picked it up yesterday and did some 40 kms and there was not a single "tap". I`ll keep posting every 500-1000 kms here so we can keep track on the manner.

Just an update after an year in with the 712. 23000 kms no issues whatsoever.

Mine has been in and motor mounts have been ordered. Currently driving the car again until they arrive. The noise is currently becoming annoying. At 80 km/h it sounds like I'm driving a diesel. Mine only started the noise at 48k km so I guess 23k is not enough to tell if the issue has been fixed or not.

I think not, mine is MY20. That being said, I know of people who had the issue with the 712 so it's not immune.

Probably you didn't see my previous posts. The noise started when the car reached 70k kms, they changed the mounts and it wasn't resolved, than they changed the GRU but still didn't stop the tapping noise just lowered the volume. Last January, when the car reached 110k kms they changed the traction motor and for the last 23k kms it hasn't had a click...

That process is pretty much what's in the TSB and the incorrect diagnosis is what's occurred in this video.

In another incident reported recently in the world of the technically-equivalent Kona EV, a UK-based Hyundai technician mentions that a failed 'grommet' can allow moisture into the motor at the tail end without speculating what the long-term outcome might be - and I'm of course referring to bearing failure and a tapping noise. That jives with the rusted appearance seen in the first video I linked above. He did say that the moisture was water and not coolant.

He's replacing the motor in a 2023 Kona EV with only 5,000 miles on it. The CEL fault that led to this was not clear and it's hard getting info out of him in the comments but I think that it was either a loss of electrical isolation resistance or a loss of resolver signal. He did say that he didn't think the issue had been resolved in the new motor but couldn't open it up to confirm that. I'll note as an aside that coincidentally the UK did have significant flooding right around this time.

Dropped my car off this morning for investigation. I watched the chap write "TSB 234" on the paperwork. We'll see what happens. On another note, they gave me a Niro EV 3 as a courtesy car. Pleasantly surprised at that - on previous visits I've had an X-Cee'd and a Picanto 😒

A tale of possible hope.

Brought the car in last Tuesday for the motor mounts replacement. Picked it up in the afternoon and the service manager told me that the noise had apparently gone. He sounded a bit incredulous himself since they have had several cars with the motor noise issue and have had to replace the motors in those.

Anyway, I drove off and where I previously could immediately hear the rattle between 18-25 km/h I heard nothing. On the motorway nothing either, where normally at 80 km/h I would start hearing a growling noise which was at its loudest at 100 km/h. Now, zilch. Over the past couple of days I tested a bit more. Going uphill would really trigger the noise at low speeds and again, complete silence, other than the slight motor whine when going up a steep (20%) hill.

I can't believe it and expect the noise to return any moment. But there does seem to be an issue with alignment of motor and reduction gear that is solved with the different motor mounts. Fingers crossed.

Mine has been at the dealer for 4 weeks now. Apparently they are waiting for Kia UK to "approve a reduction bearing repair." And I am still quite enjoying their nearly new Niro 3. But with all the recent rain, I miss my wellies - they were in the boot.

Though only an educated guess, I would imagine the hybrids will have an entirely different gear train and motor unit compared with the full EV cars. I doubt they will have the same issue. Naturally, they may possibly have their own intrinsic issues but I’m not aware of any. Peter

Is this problem issues with the motor bearings in Kia PHEV plug in hybrids electric engine to? Or just the "E-Niro and Niro EV" ?

If by Niro EV you are referring to the new model, then the answer is 'we don't know but it isn't likely'.

AFAIK it does not occur in Niro PHEV and HEV, only e-Niro (1st gen), Soull (model 2020) Kona electric (1st gen) and Ioniq (28 and 38 kWh).

There's a lot of threads about this "wheel of fortune" noise! Wasn't sure which one to update. There's this thread, plus (possibly others) :


Update - I've got my car back! 12 weeks and 4 days. The paperwork says they :
REPLACED TRACTION MOTOR ASSY (WARRANTY)
REPLACED GEAR DRIVE UNIT (WARRANTY)
REPLACE DROP LINKS (WARRANTY)

(of course the last bit wasn't "wheel of fortune" related.)

Only driven it 20 miles, but the noise has certainly gone. Time will tell. I will park up and take a look at the motor when I get home.
