In this report I thrash Hyundai's new 8sp DCT in the diesel 2021 Santa Fe for 12 rounds up the driveway from hell (tight, twisty and 5m ascent for 20-ish metres of lineal concrete).
This is an example of a worst-case scenario for a transmission like this - times 12.
Hyunda-Kia’s latest eight-speed DCT, by comparison, is a wet clutch system (meaning, the clutches operate in an oil bath) - and the oil is fed into an external convective cooler to manage overheating.
This is a completely separate oil system - as in, the oil that cools the clutches is separate from the oil that lubricates the gears.
Clutch durability is really simple to understand - all you need to know is that heat kills clutches. We’re about to put that to the test. Quite a severe one.
I want to see for myself (and show you) whether or not I can induce a near-death heat experience in the Santa Fe diesel dual clutch, by doing some severe real-world reversing.
And if it does go poopy in its trousers I’ll be reporting that, and doubtless there will be a terse telephone call with Hyundai, the temperature of which will be somewhat less than the clutch pack.
If nothing else, you know how I always say: ‘Never buy a demonstrator.’? Yeah. Well, this would be one reason why. (Actually, it should be fine. I’m told the transmission has inbuilt thermal overload protection, but let’s find out anyway.)
it strikes me that some of you really like the idea of buying a Santa Fe diesel (or its under-the-skin twin, the Kia Sorento diesel, which shares exactly the same powertrain) but some of you are somehow disinclined to buy a vehicle with a dual-clutch transmission - so scary - mainly thanks to Ford’s terrifying efforts, with its horrific ‘PowerShift’ dual-clutch transmission, and its appalling reliability.
Let's try and get a definitive result on heavy load endurance and duty cycle tolerance for this transmission.

I'm impressed. I have the 2017 USA version of the dry DCT in my Tucson and it hasn't given me any issues with low speed uphill driving. I also like to manually shift it under heavy gas pedal load while having fun with the car. I am savvy as to the limitations of a DCT. The main thing that I try to do is to give a second of time for the clutch to engage while starting from a stop. I am considering trading for a 2022 with the wet DCT. Well done Hyundai/Kia

Used to have a Golf dual clutch, when you rode the clutch for 30 seconds on a hill it automatically switched to neutral no warning or anything. Took it back VW dealer and they said it was working as designed... so the car switches the clutch off to protect it!

[@lesliedsouza4077]

Yay, John :) You kinda answered a comment I had put in, on a previous DCT show, re: reversing, uphill, with trailer. 5 in 20 is steep enough. Ok, you did clarify, that trailer reverse wasn't feasible on this driveway. You could've shown trans temp measurement before & after test? What temp would activate the warning? To get really into it - A trans oil sample, lab report, before & after test? Remember to replenish the 100 ml, each time :) As you said, even a manual trans would require some clutch slipping, in this case? This test shows the advantage of electric motors' full torque from zero revs? Bearing in mind, that motor windings can also heat up, under prolonged, high torque/ low rpm? & also have a thermal overload cut-out? If your driveway were to be straight-line, the slope would be steeper? You could use an electric winch at the top? To haul a vehicle up, trailer or not, trans in neutral? (It would need a full-wind cut-off?) :)

[@julesbarcelonarules]

Thanks for this test. Interesting to watch as I've never driven a DCT. Do you have an ETA on when your Santa Fe review might come out? Tossing up between a Santa Fe Highlander or a Palisade Highlander. Ruled out the Sorento due to seriously long waiting times.

[@zabuk9]

I find the 8spd dual clutch in my new Sorento to be far superior to the VW 7spd I had. That could overheat in slow traffic. This video has put my mind at rest about the possibility of cooking the clutch.

@@AutoExpertJC hello John, i just happened to watch this video (can't believe I have watched it till the end). I'm still trying to understand the wet DCT on Santa Fe Diesel, since I'm thinking of getting it for myself as daily driver. I'm from Asia, big city where traffic is so f up, very low speed driving from home to work (12 km). Now the question is, should I be worry with the transmission for the long haul (2 years at least)?

[@mickeyj1948]

I would be interested to see how that transmission performed with the maximum rated towing capacity hanging off the towbar.

[@rossmackay3242]

Hi John, are those tyres standard issue for the Santa Fe? What are they like on an SUV? (once you leave the driveway of course)

[@johnmurray9217]

Another concise report, thank you JC. Is the normal traffic stop/start usage noticeable, by not letting the vehicle 'creep' forward? I asked you in another comment (weeks ago) about the Toyota 'launch gear' on CVT vehicles. Would this be difficult to design/add, to assist a DCT, as it does with Toyota?

[@AutoExpertJC]

Creep is fine. Inching under load - not so much, unless for short periods.

[@Pete856]

I see the hybrid version is coming out soon (at least here in NZ where both Hyundai and Kia have announced the upcoming release of hybrid versions of Santa Fe and Sorento). I'm assuming they will also be DCTs (like the ioniq and Niro), but they have a really good trick to reduce clutch wear, they simply fully engage the clutch and let the electric motor do the driving with it producing it's maximum torque from 0 rpm.

[@AJfication]

John, one thing we noticed during this experiment is that you look down at the shift-buttons every time you change from D to R or R to D! Will be very interested in how you got on with the push-button system in lieu of a conventional (Grab and go, without looking down) T-Bar or even a good rotary-shifter. During a 3(or more) point turn on a somewhat busy street, I'd much rather keep my chin up and my eyes on the road. Maybe one more point to the Sorento??

I've got my order on a C8 Corvette with an 8 speed duel clutch transmission. My Sydney driveway is also a nightmare. Hopefully it can handle the heat.

[@GAFBear]

hey John have you heard of the EAT8 auto and any thought's on the same, thanks for reading :)

[@GlowingTube]

It’s good to see that this DCT has been well engineered. Unfortunately it still suffers from not being able to crawl in traffic, you need to modify your driving style to stop start. That I’m afraid rules this gearbox out for me... I don’t want to modify my driving style to minimise clutch wear.

[@khronin]

If you have driven a manual before--all you do is give an extra car length to accelerate.I just got a Kona N--I also just recently owned a 2020 KIA Stinger GT AWD 3.3TT and a mazda CX-30 turbo with the 6 speed and all have been fanatstic--the Stingers ZF would hunt a little in low speed driving--mazdas 6 speed--was extremely smoothe and this new wet DCT is very good--it has not been hunting gears and it shifts quicker and smoother then the autos is all i notice--it feels like a buttery smoothe auto and I am on my third day and it is easy to drive.

[@dcvariousvids8082]

When I read the title, I thought hammering round a race track and then a bit off-roading. Then you said dual clutch transmission and I then had visions of slow reverse manoeuvring up a hill, pushing a trailer. Well I got half of it. An actual automatic no problem. But for a DCT, such driving usually a recipe for having to ring the local garage or recovery truck.

[@stefanb.7781]

Guys, a question about driving in a heavy traffic, like traffic jam with dual clutch gearbox (DCT/DSG, etc.) - does it make sense to switch to manual mode, to avoid constant switching from 1st gear to 2nd right after start rolling? These gearboxes try to change gear as quick as possible, so it look like - start, 1st, 2nd, stop, start, 1st, 2nd, stop, etc. I've read that clutch may slip when you slowly drive on the 2nd gear too. So switching to manual, to keep the car permanenly on the 1st when the speed is low, should also save the clutches. What do you think?

What is the hyundai service replacement kms interval for the oil in normal service and servere conditions?

[@Dr_Xyzt]

What happens if you put one foot on the brake, and another on the accelerator? Does the vehicle know if there's enough braking pressure to hold the vehicle at a stop, so it chooses to modify the throttle position such that it holds the engine at a specific RPM range whilst holding the clutch stack in the open position? -- The General Motors LS3 drive-by-wire has a neat feature where it can add a certain amount of throttle (15% I think) in order to prevent a stall event if the vehicle is below the roll speed at idle. There's some sort of other programming where it will permit a stall event if the PCM adds throttle position for a given amount of time.

I have to say that I agree with your views about reversing in rather than reversing out. This is a safety issue. I even say this about car parks. My wife was in a wheel chair for about 6 months and frankly, the most dangerous place for her was the shopping centre carpark, because drivers reversing out do not have the vision of a driver driving forward. Also, as far as I am aware, every child who has been run over by a reversing vehicle, was run over by a vehicle reversing out. I have never heard of this about a vehicle reversing in. I used to service computers on customer sites and I did not enjoy paring in Wagga Wagga because of their nose to the curb parking, because reversing out, I was reversing into a big blind spot in my blind van. Tamworth with their rear to the curb parking I found to be far less stressful and much safer.

Good summary. I don't mind DCTs at all. Driven a few Hyundai/Kia DCTs and barely notice it. Off direct topic, but related. I would like to know if the Kia 'IVT' is actually any different to a 'CVT' as far as engineering? Smells a lot like re-naming something to avoid a stigma.

The clutches and gearbox both packed up in the Golf, and VW wanted $10,500 fix it. I politely told them to fuck off, and traded it in. While the Ford isn’t quite as refined as the VW, it’s certainly more reliable than the golf that I had. After watching this video about the Santa Fe, and the great wrap that you gave it, it’s now on the list for a possible replacement of the Kuga

@autoexpert JC, this is not clutch related, but the Santa Fe is a big unit, as are other big SUV's / 4WD's. Their ever increasing numbers in shopping centre car parks present an issue for the driver of your standard passenger vehicle. When reversing out of your parking spot, the large SUV/4WD parked next to you can present a very dangerous issue, rear cross traffic (more often than not driving at speeds well above the 5 km/hr). Gladly, more cars are coming with Rear Cross Traffic Alert (RCTA) with auto braking. With new cars now coming with a reversing camera. How difficult would it be to engineer a system where you have an additional camera on each side of the rear bumper, and when you put the car in reverse, a panoramic 180 degree+ view of what's behind you appears on the infotainment screen (or similar)? It may already be available on some models. Just curious..

[@demagab]

Where I live there is a long steep driveway with a bend at the end. Any car can only crawl up the hill in first gear, most automatics try in second but eventually downshift, but the new Volkswagen we got with the DSG transmission stays in second gears and most likely slips the clutch all the time. I don't know where it comes from but after I can smell something similar to plastic or glue. Maybe it's something else, I'm not sure and the car is not broken in yet

Hey John my 2014 fiesta with the dreaded DCT has been fine since I've owned it. And still going fine. Just treated it like a manual in regards to not letting it crawl in traffic etc. Guessing getting them hot cooks the seal leading to the oil leakage onto the clutch packs. Have also heard ( from a Ford tech apparently) that the failures all mostly were related to people who babied them all the time. Especially from new. ie not putting the foot down often enough. And that a lot of the failures were due to clutch material balling up on the clutch packs. Whereas if driven hard often enough it kept this clear. Anyway I tried to find any data on the percentage of failures of these dammed things and couldn't find much. Any one know more about the failure rates?

Watch TFL test of the 2021 Kia Sorento with the same 8Speed DCT. it did overheat going uphill offroad in Colorado winter....

Really enjoyed this review not that I'm interested in buying one of these, just your comedy sketch about the neighbours 🤣🤣👍🏼

All decent satire is reality based, loosely.

I ride a dirt bike and the clutch is used as a way to modulate the engine power (much more responsive than throttle). We ride up very steep hills with the engine at full throttle and slipping the clutch for very extended periods of time and so far I have never had to change a worn out clutch. If I was doing this to an auto transmission with a cooler I am sure it wouldn'tget half way up the hill before it overheats. Think driving an auto in second gear up your driveway for 2km. So this means a properly designed clutch will have no problem. The clutches on dirt bikes are all wet clutches.

@robert heritage I have a KLX and ride every weekend and I am surprised the clutch has not worn out. I do a lot of hard enduro on it and the clutch is like a torque converter.

[@robertduklus6555]

dry or wet clutch in kia/hyundais they both overheat quickly off road, low traction situations

[@SpencerHHO]

If you're taking them into that kind of situation, you're a moron. I wouldn't take any softroader over anything much harsher than a wet grass hill...

The true torture test would be watching the entire 29 minute video.

You said it yourself John, "DSG does not equal long-term ownership"

[@letsseeif]

Up which creek does that leave our '17(MY18) PD i30 SR Turbo Premium Hatch with a DRY CLUTCH DCT.................... as bought through AutoExpert. nb. perfect so far, but only carefully driven? :-) :-)

I would say that if you could smell an oil bath clutch it is well past the time for a tow truck.. You mentioned that a characteristic of the car is it holds speed on a downhill run far better than the Automatic version. Does it apply the brakes autonomously or is the speed hold a result of a lower gear selection done autonomously? For example a manual with to higher gear selected wont have enough engine braking to hold a desired speed. Are the clutches directly operated by hydraulics with an electric proportional valve or run electrically via a magnetic coil with a controlled magnetic field?

[@AutoExpertJC]

Nevertheless if you overheated it you would smell it. The car remained in the same gear to retain the speed.

That is fantastic, when I was selling Hyundai's around six years ago there was a problem with the duel clutch transmission in normal driving as it would overheat due to the gearbox not dropping into first at standstill (you were basically riding the clutch all the time) to overcome this you had to manually click into first gear even though the car told you it was in first. I don't remember any problems reversing up the hill. My Alfa however was brilliant in normal driving conditions but but just don't try to do what you just did you would have to rev the shit out of it until the clutch engaged and then it would shoot out in the most terrifying way it was as if the car literally wanted to kill you for you wanting to make it drive backwards up a hill. I did notice that after my last service software update the problem no longer exists so five years of playing with these duel clutch boxes is really showing huge improvements. Personally I love the duel clutch gearboxes, I loved it in the Hyundai and I love it in my Alfa which is why I am so impressed with this Santa Fe its brilliant.

Hi John, You have convinced me that reliability is not an issue. My concern is repair costs. I believe DCT quite often can’t be repaired if they do have an issue. They are much more expensive to repair than a standard automatic and much much more expensive than a manual to repair. I have been told that in many situations you have to replace a damaged DCT because it can’t be rebuilt. Is this a fair comment or am I missing the point?

[@iandoyle5243]

John, is this an issue that no car manufacturer wants to discuss? A mechanic friend said do not hold a car with a dct if it is out of warranty. Replacing a dct is just to expensive. Is this an over simplification?
