Title: 2017 PD i30 DCT Issue
Post by: elantraelite on August 09, 2018, 04:12:27
Hi all,

Never thought I'd have to post this, but we're starting to have some trouble with out 2017 i30 SR 1.6 DCT

It's happened three times now.

My partner was slowing down to enter a roundabout when it wouldn't engage again to pick up speed.

My partner isn't 100% sure but doesn't think the car's rpm's were increasing when he accelerated.

After releasing the accelerator and repeating one or two more times, it finally got power, picked a gear and has work fine since.

Has anyone had this issue?

Between my Santa Fe and the i30 and both being our first auto cars... Not impressed. I miss having a manual.

It would seem that you are only assuming it is the transmission...."partner isn't 100% sure.... "

He was accelerating but car's rpm's were not increasing.  :wacko: ????? Was he idling in Neutral down a hill ?  :cool:

True, it is assumption, that's why I just wanted to see if someone has had a similar issue.

He applied the brake to slow down, then accelerated and no power. Foot taken off the accelerator, then tried accelerating. No power, foot off accelerator, then tried again and finally picked a gear and kept going.

I did stress that he needs to take more note of when it happens.

Maybe means :
Moved accelerator,  but no change in engine revs. 
Engine revs changed after a couple of tries.
Are these "fly-by-wire" ?

Hard to be observant when you're going WTH !!   :D

Hi Dean, Nothing like that in first 31K but i have no reason to doubt your partner (it is easy to have self doubt in these situations).

I'd be getting it thoroughly checked at next service. Don't suppose it has thrown any error codes via Autolink. That would be too easy. :crazy1:

Hi,

Yeah, have had this happen twice when slowing down to merge into a highway lane, trying to then accelerate to complete the merge, the engine revs but nothing happens, seems to be in neutral/no gear engaged, I've instinctively moved the gear leaver right/left (to go between Drive/Manual) and then the gear engages. A bit scary when it happens. I've put it to down to the DCT's idiosyncrasies/confusion. This is my first auto too, miss the manual too!

Hmm sounds the same.

Thanks for the tip about manually dropping a gear.

We'll book it in to be checked.

Technology, great when it works, can't beat the simplicity of a manual transmission.

Agreed regarding manual transmissions.

Hi,

 the engine revs but nothing happens, seems to be in neutral/no gear engaged,

Thanks that's a succinct explanation. It may fit with elantraelite's circumstance

@Pappy thanks for your input, however, we have smooth operating transmissions ('fluid' auto and DCT ) in our advanced technology there is no room for "the DCT's idiosyncrasies/confusion."  Go to your dealer and get the fault fixed.

Probably not...

But after owning 5 manual cars... None never had a transmission problem over the 800,000km travelled across all of them...

Our family first two autos having travelled 50,000km between them.. so it's disappointing.

Best car I ever owned was still my old X3 Excel. Treated it like crap and it just kept going.

From early chats with Dean, I know he has a prejudice toward 'automatic transmissions'. I think I talked him round ...briefly.  :mrgreen:

 There are essentially two auto systems: fluid driven and dry clutch (DCT).
The fluid/torque convertor transmission has been around for decades. It is in virtually every taxi in the USA and Oz. No problems, but not as sporty as a manual box.
I worked for the Dutch Philips company; by 1970, our entire fleet of service vehicles were automatic because of reliability and the absence of clutch renewal.

The DCT is the new boy on the block (comparatively speaking) overall it performs well and has the same or better power transfer as the manual box.
However, there were early issues in the USA where it appears the Tuscon and Santa Fe were suddenly 'in Neutral'.

I have an 80,000km 2015 GD, with DCT. The clutch engagement motors are rattling, but it performs perfectly. :link: Dual Clutch (DCT) Noise (https://www.i30ownersclub.com/forum/index.php?topic=50669.msg464785#msg464785)

Now Dean before you say  "that proves it all"  :crazy2: , as much as I searched, I could only find one other example. As I posted , the owner in the USA told me Hyundai had replaced his transmission twice.

If it gives you some comfort Dean, on the DCT reliability issue, I remain with a foot on each side of the barbed wire fence.  :scared:

Post by: ricleo on August 17, 2018, 07:04:41
this "issue" occurs in Singapore as well from my own experience, and also from owners giving feedback on a local forum and facebook page.

i only experience it in a very specific set of circumstances. during moving off, when i am very light on the throttle, gear engages 1, 2, and if you lift off the accelerator at this point, the DCT doesnt know what to do, and that's where that feeling of neutral happens. accelerate and no power. The DCT probably thinks, ok driver lifted off. prepare to downshift to gear 1. howerver we accelerate again, and it has to move and find gear 3 instead, and that takes time.

most of the time i step on the accelerator firmly, so the above scenario seldom happens to me, only twice so far in 6000km of ownership

Post by: beerman on August 17, 2018, 11:54:35
I thought of the DCT video from the auto bloke that Dazz posted a while back. It explained the transmission to me and how the transmission preselects the next gear with the second clutch and if you do something different it takes some time to adjust. This is why on occasion the transmission may take a second or so to workout what is happening.

Especally when you are on the brake and it expects the that it will have to change down a gear and then you jump on the gas. In this situation jumping on and off the gas may not be the best way to help the transmission make a decision on what it should do.

Not saying there isn't a problem though

Post by: nzenigma on August 17, 2018, 23:03:13
One would think that there should be no delay, electronically, decisions are made in nano seconds.

Isn't this why we are kept safe by predictive cruise and braking and have ethical choices made for us when we need to run down the granny or the cripple on a pedestrian crossing.  :whistler:

Hi Guys, Sorry to add another topic to this issue but its been bugging me for awhile in regards to the DCT as well. For any PD SR owners out there with the DCT. Do guys hear a slight rattling noise around the transmission shiftier when accelerating. From what I've observed it's audible from about 60KM  - 80KM when your accelerating. I'm just finding it a little weird and worrying coming from a kia with the same DCT its weird hearing that noise.

 I would be inclined to look for something tapping near to the shifter. It is quite remote from the transmission.

Hi again,

Well it happened again. Definitely a DCT issue. Stopped at the lights, went to take off the engine just revved and didn't move. Turned the car off and back on and it was fine.

Quite dangerous given my son was in the back seat and the person behind almost hit us!

Time to take this piece of crap to Hyundai to sort out!

Bummer,  luckily all ok.
I've said this before , whenever it plays up,  either leave it  where it is, or, park it up and get it towed by Hy Assist to your dealer.  A record of problem and frequency  will be created.
If anything does go wrong, it may help with insurance. 
Hope it's sorted soon.

This seems to be the same , or similar, fault.

As Mick says, get it to Hyundai. You may be lucky enough to find the correct software upgrade. If not, when it happens again park it, as Mick has also said, and don't accept "technicians cant replicate the fault".

Hey all :) new to the group . I own a 2017-18 Pd i30 sr premium with 7500klms on the clock .  and have had the same issue with the 7speed dct . I was at a T junction and went to take off and the box neutralized ( limp mode) has no acceleration what so ever but was not revving as if it was in neutral . Had a big ass hilux heading straight for us and almost got T boned . Had to release the accelerator pedal and punch it again to avoid a mijor accident with the kids in the car . Spoke to head office Hyundai and my local dealer and they think I’m losing the plot . There answer was if it doesn’t happen to them whilst driving there is no way of them diagnosing it . It was put on the scanner for its first service and diagnosis showed nothing .
In my opinion if this isn’t sorted I think I will take this further because I truly believe my children’s lives are in danger if this was to happen again whilst my wife and or myself was driving . Truly love the bloody car but this will end up being another takata air bag situation where people will be seriously hurt . Anyways thanks for letting me vent . Be well people .

I would speak to them again, record the conversation and at the end of said conversation ask them if these are the new higher standards of warranty care they gave assurances to the ACCC about.

If that does not get their attention, call the ACCC.

At the very least they should be trying to fault log the vehicle to identify the fault.

One things for sure, your not making it up.

Welcome Odd351,

That's very worrying! Feel free to refer them to this thread and anything similar you can find on the web. Beerman is wise far above his user name. His suggestion is a good one. Contact Hyundai Australia as well and say exactly what you have said on here. They need to put themselves in your shoes.   :disapp:
Title: Re: 2017 PD i30 DCT Issue
Post by: elantraelite on October 29, 2018, 10:34:50
We're still having the issue with ours and not much luck from Hyundai.

We'll be getting rid of our i30 before the warranty is up. Never want another DCT again. We should have bought the new 8spd 2.0 turbo Sonata with a standard torque converter auto.

Disappointed Hyundai couldn't get DCT right.

What does it say when Hyundai have not dropped the 1.6T with DCT from the Tucson in the states and replaced it with a 2.4 na and standard 6spd auto?



Title: Re: 2017 PD i30 DCT Issue
Post by: beerman on October 30, 2018, 01:10:18
Another thought...

When you were approaching the intersection were you slowing down, saw a gap in the traffic and jumped on it to go through?

I suspect if this is the case what has happened is you have confused the transmission. The Duel clutch always has 2 gears selected, the actual gear you are using, and the next gear the car believes you will need. For example slowing to a stop, it might be in second gear and have 1st selected ready to go next, as the car is slowing. By jumping on the power to go into that gap, the transmission is blindsided, and needs a second to reselect the new gear, ie drop first and go to third. Hence the delay.

I was able to replicate this in my car driving home. While slowing to a stop I jumped on the power and the car took a second to reselect the right gear. Much the same way as if you selected the wrong gear in a manual transmission, there would be a delay while you realised what you had done, and corrected the error.

Remember the DCT is much more like a computer controlled manual than a traditional automatic, hence it does not need a torque converter, is lighter, can handle more power and is more economical.

This nice fat guy explanes further...

I thankfully haven't had this happen, however the DCT is a jumpy thing isn't it!
Only problem is leading up to roundabouts that are extremely busy and you need to be quick off the block, I have 0 power unless i put it into sports mode and fly off the line.
True, it's different to an auto that i'm used to, but during the test drives i didn't notice this.

Kinda wishing i stuck with my older i30. Paying $120 a fortnight for this car with the warm start issue as well is starting to outway the fun.  :undecided:

I find that too often the DCT upshifts when you lift off the accelerator and then when you need to get going it's in the wrong gear - a bit frustrating, this is the first "automated" car I've had and it's taking some time to get used to its idiosyncrasies.

Hi All,

Just had the 10k service and raised the problems I'm having with the DCT (clicking noises while driving, revving & no acceleration, shuddering on 2nd gear engagement) - DCT checked out OK apparently.

The tech "carried out DCT relearn function" - this has dramatically changed the DCT's behaviour - seems smoother and working better - will need to monitor it for a longer period.
