angeluchoo · **October 02, 2012, 05:07:24**

Hi I own an i30 SLX 2008 Turbo Diesel I have had transmission trouble & i am at the moment trying to get more information on this problem, I am fighting Hyundai Australia as they will not cover the warranty & its a common problem in the i30.
Thank you.

Welcome angeluchoo,

Yes, there are a few issues with the auto''s, but not enough to be called common.
We have 2 in our house 2008 + 2010 both autos and no problems at all.

It would help if you could describe your problem in detail.

How long has it been faulty
Symptoms of the fault
What action have you taken
Hyundai's response
Dealer's response etc.

We do try to help here, there is a search function at the top of the page or look in the diesel section of the form topics.

Hi, thank you for your response, the trouble with my transmission is that there is no transmission no gears at all total collapse, there is a common problem with the four speed gearbox's thats why they moved to a six speed box with the new model. I'm trying to get any information that can help me fight my case. Thanks

Hi & welcome to the forum.
What sort of service history does your car have?

Welcome angeluchoo

Sorry to hear your troubles. I tried to start a poll to narrow down the models and build dates affected but got little or no response unfortunately ..

It does appear to have been mostly 2010 Diesel Autos so far...

I have kept my eyes peeled regarding i30 auto gearboxes - as my own failed & was replaced under warranty. However I have not heard symptoms as you describe. I would say also that the "old fashioned" torque converter ie 4 speed gearbox was one of the atttractions of the i30 for me - as although it is not (in my opinion) the best, it is all very well proven technology.
Good luck with the dealer - else try to get the unit to an auto gearbox specialist.

I have a 2010 i30 diesel auto, so am interested and a little concerned about this thread.
The 1st thing I don't understand is why the dealer won't honour replacement. Don't they have a 5yr warranty?
I'd also like to hear how it starts because on a recent trip, I had my engine light come on on both legs of the journey at around the 6hr point.
Hyundai found nothing the 1st time (waiting for inspection following 2nd occurrence), but they did mention something about a gearbox synchronization (or something like that), error.
Worried now that this may be the early indication of a gearbox failure???

Apparently, there can be a sus selector valve which need replacing. It's rare though but nevertheless it can happen.

My understanding is that the 1st indication that things are not ok is a delay when selecting gears, particularly reverse.

We have 2 in our family and at the 1st sign of that, they'll be back to the dealer for serious discussions. You can mention the forum and that there are records of people's experiences of this fault. According to this thread repairs seem to be quite variable by dealers, ranging from both extremes. I guess each fault has to be individually weighed on it's own circumstances.

However, considering the number of diesel autos in Oz, it's still quite rare for anything to go wrong IMO.

Hi thanks for your reply, i noticed my gearbox surging so i took it to my mechanic he couldn't nothing wrong 4 months down the track total collapse no gears at all but no engine light came on but i do know that a friend his light came on & it was the clutch that failed it was an automatic gearbox

Just for clarification; torque converter type automatic gearboxes do not have clutches (at least not of the sort that manuals have). Perhaps something was lost in the telling/translation.

Is your car not in warranty? If not I hope it's a simple fix.

they've got wet clutch packs, normally 2 direction packs and then one pack for every speed in the transmission. if one of the direction packs failed or the first gear pack (or the seals on the piston for engaging the packs) this would result in no drive. more likely that the oil pump would have failed though, with the effect of there being no oil pressure to lock up the appropriate clutch packs to move the car

You managed to quote me while I was expanding my statement... thanks for that extra information.

Some warning signs to look out for. Thank you.

I have noticed a delay in engagement, at times, when selecting reverse. However, it only seems to be when ive been in a hurry and have selected reverse immediately after the engine has turned over. I just put that down to the engine not yet had time to build sufficient oil pressure to properly engage the transmission.
On those occasons, because of how quickly i select reverse after engine firing, i could hardly deem my use of the vehicle to be "normal" (never experience delay if i allow a couple of seconds between start and selecting reverse) and so havent ever considered that an engineering fault. Things are designed and tested to operate in "normal" conditions.

I'll pay a little more attention now that the delay is believed to be an early sign of transmission failure.

I'm still not clear on why warranty replacement has been declined.

I'm back to the dealer on Tue to have vehicle inspected and engine warning light reset. They told me that as the vehicle is running fine with the engine warning light on, that I'm fine to continue driving the car until they're able to inspect the vehicle or engine performance is impaired.

I'm going to ask them about transmission failures with my model. I suspect I'll be told there's been no problems, but will ask anyway.

Will post up anything of interest.

@300pete,

Perhaps learn to slow a little, relax and enjoy life. No need to rush everywhere. Based on what you just described, I would not class that as a fault.

That's right. Older technology is not always bad......4-speed gearboxes have been out for aeons and proven technology....God knows the problems that will surface with the new 6-speed gearbox on the i30....especially now that everything is electronic I would suspect more faults than before....

My problem with the auto in my GD Diesel is that an actuator or something similar has failed. Every time I need to take it out of park I need to use the shift release with a pen. They are going to fix it under warranty, but bit of a concern that the car is only 4 months old and only done 13000 Km's

angeluchoo,is the Hyundai dealership not wanting to honor a warranty claim on your auto trans because you had taken the car to your own mechanic first?

what colour is the trans fluid on the dip stick,if it has any on it.

Just an update on my 2010 CDI i30 auto transmission problems. Engine management light has come on 2 or 3 times since my last post. All 3 times, I have been towing a trailer. No heavy loads, would be nothing more that 300kg and sub 75kg at towball. Engine continues to operate faultlesslly, but the damn engine light is on.
Took it in for 75k service last week with engine management light still on. They've done the service and have asked me to bring it back next week to have the transmission valve body (their words, not mine), replaced. It's being done under warranty which I'm please about because they showed me the parts list and the valve body alone was +$2k and all up parts came to around $3k!
Hopefully that fixes it and I never have problems with it again.
Regarding warranty, my few warranty experiences (Australian ones), have be favourable, with every failure / defect to date being covered under warranty. Even a key which the buttons had worn through on. My dealership did tell me that they do have to get their wording right with some of the "grey area" items

I'll post up again to let everyone know how the mighty i30 is after valve replacement surgery and 1st tow job since.

Cheers...

Good to see a dealership thinking in order to get the warranty claims through and look after the customer.

It used to be the case that it was taboo to pull a trailer or caravan with a torque converter auto box unless you had an external oil cooler fitted. In the early days VW claimed that it was one of the advantages of the direct drive DSG gearbox that it could be used for towing.

Perhaps things are different today.

VW have obviously revised their thinking. The VW Amarock 2.0 diesel with a ZF 8 speed auto (not a DSG) has a higher towing capacity rating than the 6 speed manual, albeit that the auto is tuned to deliver greater torque (420Nm) than the manual (400Nm).
