It has been brought to the Mods attention that apparently there is "known fault" with the auto transmission on the i30. 

The person bring this to our attention hasn't indicated what the exact fault is.  However, they say that whole transmission has to be replaced and that there is a month wait on the part.

Are any members aware of a "known fault" which requires a complete new auto transmission box on the i30?

If so, can you post details.

Thanks in advance

This sounds very sus to me. All years & all engine combinations and they find out now! I don't believe it. 

[beerman]

Seems to be shroud in secrecy,  as those who have had the new box put in have not been told what was wrong with the old one.

Could go beyond the I30 too, as a Santefe at work recently had the box replaced as well.

[Dazzler]

I'm still of the opinion that it is from 2011 onwards (as earlier models seem pretty good in that regard) even if they were only 4 speed old tech...

Maybe it is sabotage by rival carmakers

Was this person from Hyundai? 

[Ugly Mongrel]

I have an auto MY10 CW. Nearly 50000km of trouble free gear changes. 

No complaints from this Ugly Mongrel.

53k here, all ok, touch wood.

Dont know if this clarifies or helps .....
I have recently had a new gearbox fitted to my UK spec /Czech build i30 CRDi auto (built mid 2010 ie 2011 facelift).  So car was about 1½ years old when all of this started with about 15000 miles.
It started with inability to kick down from 40-50 mph when in 4th (about 1500 rpm) - it would kick down to 2nd instead and with an alarming thump, sometimes with most alarming judder & squeal.  The fault occurred more frequently with time, more often when car was heated up.  My helpful dealer (I understand) reset ECU, reset injectors, changed gearbox oil to no avail.  I gather no error codes.  The car was never undriveable, never stopped going, and never displayed any lights etc (I just learned to drive around the fault - eg manually changing to 3rd - as it is so alarming when it happens).
New gearbox is now in, fitted and working fine.
Whilst of course I am not impressed with the failure of a gearbox in such a young car, my dealer & HUK dealt with it all smoothly etc and so I can have no hesitation in buying another Hyundai, and most certainly no hesitation in dealing with this (multi franchise) dealer again - one day.

Mr Hoarse,

May I ask , why are we just hearing of this significant event 

[Doggie 1]

Thanks for that update Ed and I'm pleased that you are happy with the service and the result.
Dave

[Surferdude]

But that's a European built car and we seem to think this message came from an Australian with Korean build.
ps. Glad Ed's has been rectified so efficiently.
I might add that we quite often have goverment, semi government and council  vehicles in for tyres and there doesn't seem to be any dissatisfaction with the cars by the drivers.
My daughter did some work experience in the last semester of her degree with Brisbane City Council, Logan City Council and Qld Health and spent some time in their cars, some of which were i30s with no unhappy observations being made.

[Talking Hoarse]

Mr Hoarse,
May I ask , why are we just hearing of this significant event 

I can only assume that you haven't been looking!  https://www.i30ownersclub.com/forum/index.php?topic=11232.0   
However you are correct partly as I have not really shouted out very loudly about my gearbox problem (much). ....
I am a little guarded about shouting out on such forums - ie in public - as I think we would be naive to assume that either HUK (or even clued up dealers) do not have a sniff around occasionally.

Meant to add earlier that I am not aware of a months wait for the part (gearbox).  As far as I know a few fixes were attempted to no avail, the diagnosis was made, authority was sought etc by warranty manager, and the car was then booked in at a convenient time a few weeks later.  However I understand that the gearbox was not ordered until my old one had been removed & examined.  My car was "in" for about a week - so I assume the new gearbox came within a few days.
I was never off the road as my car was not out of action except when booked for repair and the dealer provide me with a wholesome "lendy car" (a fresh little i10).

Do we know if the auto gearboxes fitted to Czech build cars are same as Korean builds? 
Are petrol auto boxes same as diesel? 
What is the prob that is reported on other cars?

Long live my new gearbox.
Ed

TH, I checked your previous reference and there is no reference to an imminent transmission replacement, so this was most unexpected. I hope too, that this resolves your problem permanently.

Mr Eye30 - out of interest - did you ever get to the bottom of this allegation?  I presume it was about UK /Czech build cars in view of your own location.

The person was from OZ so presume Korean build.

Emailed the person in April and they said they would get back with more specific information.  Never did get back.

Due to your post I've just emailed them so if I do get any more info I'll post.

[Dazzler]

My Auto Transmission Poll has been read 34 times but no "votes" or comments from effected owners yet (posted almost a week ago) 

So does  that suggest it is not a high percentage or are the owners so disgruntled they are not bothering with our site.. Only Mel and Talking horse come to mind  - I know there have been a couple of others! That is one UK and one OZ 

I tought the poll was a good idea to try and isolate the problem, but no good if effected owners don't use it.. 

[beerman]

G'day all,

I still suspect that the fault is an isolated one, though if it takes until 60-70k there is a fair chance that a lot of 2010 Hyundai's haven't been driven that far yet. I do a fair distance and I've only done 56k (though I could have done more, but have been keeping within the 25k/year required by my lease and putting the balance on the wife's car, that only has 117k and is an 03 model).

I guess the next 12 months will put me in the red zone....So I'll let you know.

[Dazzler]

Ta. I'm guessing yours will be fine (touch wood) 

[komaterpillar]

Technical service bulletin for torque convertor/oil pump seal failure, and case porosity in the front half of the case behind the torque convertor.




and this is an extract from another TSB about the case porosity



i remember reading in another TSB that it was only the earlier manufactured cases that were affected, and that there was an updated version of the front half of the case in later models, can't remember the dates though, or find the TSB 

[Talking Hoarse]

Thanks for all the info so far. 
The TSB's imply an oil seal or leak - mine was certainly not dropping any oil as I would have been rather disgruntled if it did so on my "new" paving....

Ok I've had an update and the person is happy for me to share with you.  It is quite long so here is a summary:

After complaining to Hyundai Customer Care (Nationally) they arranged for the car to be repaired by a  transmission specialist and not the Hyundai dealer (the work was outsourced).

They remember asking for a printout of the problem/work done but there wasn't one.

They were told that the whole lot, (I presume the transmission), was taken apart and many parts replaced, new seals etc.

They have had the car back a week or so and will be taking it for a drive out on the open road to see how the gear changes are now.

They finishes of that a further request has been made for a detailed summary of what work was actually done and if one is provided it will be shared with me and I'll post here, with their permission..

[Dazzler]

Thanks Lester 

[beerman]

Whilst I too hope that we find out what was done, I am willing to bet that one won't be provided.

This would be on two counts, one my distant memory of a warranty condition which basically says 'we'll fix it, but don't have to tell you what we did' and 2) if they take an old tranny out and put a new one in, and send the old tranny to a 3rd party to be reconditioned, there is a fair chance they don't actually record what they did, other than a full reconditioning (the Australian Standard of which I have posted elsewhere).

i have just come across this thread and am happy to share what I have discovered about I30 transmissions
* in my Jan 2010 build I30 both Petrol and Diesel share the same transmission - the diesel transmission has trouble coping with the torque of the diesel motor which causes the valve body to wear. If this is caught early enough its a simple replacement of this part.
* when my car started having problems (probably started at around 45000kms) I notice a definite lag in engaging reverse and over time the car seemed to struggle changing gears sometimes over 4000rpm before gear change would engage, usually on a hill ( this only ever happened twice to this degree and both times an error code was registered -
P0700 – Transmission Control System Malfunction
P0741 – Torque Converter Clutch Circuit Performance or Stuck Off.
* another warning sign is burnt transmission oil - which should of been picked up at dealer service.
*my transmission was replaced at 73000kms with a reconditioned transmission. This had come from a transmission specialist (I believe based in Melbourne) that Hyundai employ to recondition faulty transmissions. It can be a week turn around for the dealer to take your transmission out send it off to the specialist and they send a reconditioned one to replace it. Your transmission then gets fixed to go into someone elses car.
* when i inquired about a brand new transmission they said it would be over a months wait as one would have to come from overseas as they are not stocked in Australia and I wouldnt get one as my car had done far too many kms (so much for unlimited km warranty and this was told to me by the dealer service centre and not Hyundai)
* at the 90000kms service I reported that I noticed that the lag in reverse and the deep grumble in changing gears was back. They test drove the car and couldn't find a problem but told me to monitor this. At the 105000km service they asked about the lag and I told them it was still there and was worse. They drove the car again with no issues ( a 2 minute drive over hours a day spent driving the car?) but were happy to except that there might be an issue and are going to replace the valve body to be sure.
*When I take it back in (still waiting notification that the valve body kit has arrived - now 4000kms later) I will inquire again as to what the problem was with the original transmission will let you know how I go.
a friend came across this article on RACQ website:-
http://www.racq.com.au/motoring/cars/car_reviews/used_cars/by_make/cars/hyundai/i30,_2007_onwards this article from the RACQ written last November also touches on the valve body being the cause of the slipping transmission....

[eye30]

Mel,

Thanks for sharing

I've not had any further update so presume no further info to share.

[Dazzler]

Thanks Mel, excellent ..

I wonder what is different about the 2010/11 transmissions though as can't recall a 2007 to 2009 auto diesel on here having this issue 

If you are reading this UM what mileage do you have now and what month and year is yours? 

[rustynutz]

Thanks Mel, excellent ..

I think you'll be struggling to find an issue with a 2007 auto diesel, Daz.....

Still nothing to report. 

Touch wood.   

[Mel]

ok today I was back at the dealer for the replacement valve body. I was told today that a problem has been identified with the premature wearing of the valve body which is causing the problem and it is now a recognised issue.  There is now a new and improved valve body that "should be much better" in the words of the service staff. When I enquired about the report on the initial transmission and what was the problem they told me that they dont get informed about what was the problem it gets reported straight back to Hyundai as they are the manufacturer so perhaps this is where the fault has been identified.

My advice is any lag in the change of gears particularly reverse, a deep grumble when the car is trying to change gears or super high revs when changing gears would need a trip to the service centre with mention of the valve body. What takes them a few hours to fix makes such a difference.
 
 I must say it was a dream driving home once again feeling like a new car lets hope it stays that way
