Disappointed (gearbox replacements)

Yea I'm just projecting that there will be trouble. There are lots of people reporting this issue. It's hard to deny that it's a problem. I'll report what happens after Friday.

 

Sounds like some of the dealerships out there are not being very helpful. So far I’ve not seen any paperwork on the reduction gearbox fault. When they first checked the vehicle they told me there were no fault codes in the electric/electronic systems. To me that makes sense as the fault is clearly a mechanical one. It was Hyundai’s tech support people that gave them the go ahead to change the assy.
I maybe fortunate that I have had a good relationship with this dealership over the years, so they were willing to take my complaint at face value.
Again, I hope people start listening to you and give you the support you deserve, these are not cheap cars!

 

The oil in these reduction gearboxes should be changed at around 196,000km which effectively makes them ‘sealed for life’ units. The technician told me that the oil in my original gearbox was black. Something I would not expect in a gearbox of less than 15,000km, the second unit (apparently new, although I didn’t see it) had metal chunks in the oil. Both of these instances along with many other reported transmission issues should be making Hyundai sit up and take notice.
I was shown the new gearbox before it was fitted, the reduction gear assy comes complete with the differential. Perhaps the problem lies with the diff. Just a thought.

 

Some years back, Hyundai replaced the transmission on my Sante Fe Limited under warranty. There was definitely paperwork which needed to be signed before they turned the car back over to me.

 

So far I’ve seen no paperwork other than my initial visit when they said they heard no noise on their test drive, but a tech heard it when I drove it! However, it didn’t stop them ordering a new g/box at that time.

 

@MLKFLOT your kona still silent? Im going on my second gearbox with more sound than before. I want them to replace the motor for the supposed new revised part but just wanted to know if your gear box only replacement was still working well.

 

blakehaas, MLKFLOT, electric eddy and TheLight75,
I am now 1000 kms since Hyundai replaced the Traction Motor Assembly and the clicking has not returned. Here are the descriptions and what I think are the part numbers as per the printed invoice I requested from my dealership.
"Engine - replace Traction Motor Assembly (365000E701) for Clicking Noise as per HYTAC 4721 W 4.90
Bolt - Flange (1140412756P)
4850 abnormal noise 36500R1H, N29, C11 4.90 confirmed customer complaint. Replaced Traction Motor Assy as per HYTAC for abnormal clicking noise. Test drove vehicle. Noise now gone, all OK."
I sincerely hope that this helps you with resolution of your KONA issues. Good luck!

 

Thanks for the update. Looks like they replaced your motor! I will take this evidence to hyundai. They want to replace my gearbox AGAIN.

 

Blakehaas, so far so good on the second replacement gear reduction unit. I did have a little panic attack when I thought I heard the noise again. I went straight to the dealership to warn them off. I’ve not heard the noise again (I’ve done about 1500km since), I’m beginning to wonder if all I heard was road noise from the winter tires I’d just refitted. Anyway, I’ll keep you guys posted if there are any other developments.

 

I've taken mine in this past Saturday. The dealership did not call today with updates, so I called them. They said they still haven't figured it out and are in contact with Hyundai tech support. Do you have any more information off the invoice regarding the diagnosis process/repairs? I'm trying to gather as much information as possible so my car isn't just sitting there for weeks.

 

They have replaced my gearbox twice now. The issue is with the mount on the motor or the driveshaft alignment which seems to be fixed when re-installing a motor.

 

A new motor, or reinstalling the existing motor?

 

No one knows exactly what a permanent fix is yet.

 

The question is also why it only happens on certain cars. Stageshoot in the UK has over 50k miles with no issues. I have 16500 right now with no issues.
Installing a new transmission without a design change is doomed to repeat the problem..

 

Hi all. I'm getting ready to purchase a 2020 (a MD dealer might have one in a few weeks) and was wondering if anyone can gauge how many of the folks here in the forum are having problems like this. I can't really tell if this is a systemic problem or not. Doesn't seem to be too much traffic on the FB group about it. I'm just worried it might be too soon to buy this car. Any thoughts?

If you bought a 2019 at any point it seems the same unrevised components were used throughout the model year, even then the problem occurrence is not universal, plenty of 2019 model owners are not having problems. Its unclear if its a substandard/poorly engineered component failure or assembly deficiency. Its also unclear despite motor revisions if and when any corrective measures to 2020 models have been applied and honestly there are not enough 2020 owners reporting in yet to give you any statistically appreciable idea of resolution.

 

Not sure what the actual numbers or percentages are, as only anecdotal reports on the forums. I am over 12K kms now, and no weird noises (other than the VESS) or any other problems so far.
