A few days ago, I saw this post on Reddit:

Anyways, before you read on, I would like you to read the post.

  1. The AWD transfer case appears to be sealed and cannot be serviceable.
  2. The Magna Actimax when used on the BMW xDrive appears to have been known for failures.
  3. It is looking like there may be issues down the road for the Genesis HTRAC versions, as they use this case.
Anyways, the original poster was a Hyundai tech, and I've interacted with him on Reddit before, so I do have some trust for the poster. The fluid, Shell TF0870 can be bought online, but if the unit is sealed, then we are out of luck.

This will also be an issue on:

  1. The 2015/2016 DH Genesis HTRAC
  2. All Genesis G70, G80, and G90 HTRAC
  3. The AWD versions of the Kia Stinger
  4. The AWD versions of the new Kia K900
  5. Whatever future Hyundai, Kia, or Genesis HTRAC versions
So quite a few people are going to be affected on this forum.

This is not a cheap repair we are talking about:


47300-4E000 is the part in question (Kia has a different numbering system so I'm not sure about the Stinger).

What is the failure rate? Personally, I'm not concerned as I don't expect to run out of warranty. Unless you know the failure rate you cannot say if it is a big deal. An anecdote is not a statistic. Is the Hyundai/Genesis case the same as the BMW or have there been changes to improve it?

Have there been many Hyundai/Genesis complaints?

If the fluid was changed, would that alter the failure rate? It may or may not be relevant. If you attempt to change the oil you will void the warranty so if under 100,000 miles you are better off waiting.

Any mechanical device will eventually wear and fail.

The issue here is that not everyone on the forums is leasing - or planning to trade in.

I think that we will, have to wait a few years to find out if this is a major weak point on the car.

The problem I have with this right now is that they made a part where the fluid cannot be changed. The Hyundai HTRAC is based on the Magna Actimax, which is the same system that BMW uses.


The xDrive does have a bad reputation elsewhere. Hyundai claims that they enhanced it, but I'm not entirely sure how or if this affects reliability.

Yes, any device will fail, but fluid changes can certainly extend the life of parts. I've always tried to change a bit ahead of the intervals.


Ford is surely not the only company where you want to be ahead of the intervals.

So we get Austrian built units and BMW gets Mexican built units?
Anyway sounds like a lot of fear mongering to me.
Maybe BMW tuned it too aggressively or did something else stupid to it during customization!

I can't find any where in the owners manual that says to ck or replace the oil in the transfercase, it does however tell you what oil and how much it takes

If you are a second owner, then you do not benefit from the 10/100000 warranty. I would be interested in the range of likely total repair cost ( parts and labor). I am considering purchasing a 2015/2016 Genesis AWD. The cost of this repair is something for me to add into my budget. The possibility of a need for this work won't discourage me from getting the car; but it will give me another repair to consider in the long term if I play to drive my car for another 100,000 miles. I had an 1999 Audi A4 and I had a year with over $5K in repairs and maintenance. This is the price of driving a nice car.
