Plenty of information on the reliability of powershift and vag dsg auto boxes but hear little about Kia dual clutch reliability

Does this mean no news is good news Are they reliable does anyone know

The reason for the lack of info on Hyundai/Kia DCT boxes is due to them not having been around for long. The Stonic and its sister car, the Hyundai Kona, have only been around since mid-late 2017 and have only ever had the DCT as the auto option. But the Ka Ceed/Hyundai i30 (the golf sized cars) were TC auto up to 2015 (i30) and 2016 (Ceed).

While i'd be very wary of buying anything with this type of gearbox used, as a new buy, i'd probably be OK with it assuming i was happy with the shift quality regarding things like pulling away and reversing up a hill. And with the 7 year warranty you get (on the Kia), that should provide peace of mind, at least for the duration.

Thanks SLO I did not realize they were so recent That is why there's no info

Nice to get praise but bbd isn’t my alter ego. I completely agree with his answer though.

The DCT boxes are also used in the Kia/Hyundai hybrids - but as above, they've only been around since 2017.

Have a Kia Niro - bulk of mileage on (Spanish) motorways at legal speeds - in 18 months averaging 58+ mpg (local travel about 65 mpg). Rarely get in traffic - until yesterday, with the approach to Madrid, where it crept along on battery power OK

John Cadogan (YT channel) has said they've been used in Asia and Down Under on Hyundais and KIAs for quite a bit longer without much of an issue - I suspect that if you use them as intended - as an automated manual and not 'creep' in slow moving traffic/keep it in drive when stopped on the brakes, then you'll be fine.

I often wonder if driving them hard is a problem too?. I remember when the Golf GTI first became available with DSG and it was something like half a second quicker to 60mph than the manual. So drivers who were more interested in outright performance than tactility might be encouraged to buy one over the manual, use it hard, then sell it on to some poor unsuspecting person who doesn't know the car has been utterly ragged and ends up paying the price?.

There does seem to be a general agreement that buying a used car with a DCT gearbox is a bad idea (that includes me). But if the car is driven with a degree of mechanical sympathy, they maybe are not too bad?. Trouble is, how can you tell how a used car has been driven or looked after?.

Tyres wheels and brake conditions can all tell their story, though all these can be silenced by a new set of cheap ditchfinders the wheels blown in by the smart paint guy and most people don't appear to notice the brakes inside sparkly wheels and tyres painted on shiny goo unless they're admiring the bright paint that's been applied to calipers to make them look sporty, apparently.

Anecdotally i collected a load of brand new cars at the docks one day, and upon inspection spotted the front tyres of a hot hatch were almost bald, scrubbed the way only serious thrashing and wheelspinning could do, first thought was they'd been swapped, but closer inspection revealed rubber debris burned into the plastic inner wheel arches and the lower sill covers both sides, all hell let loose when i reported, but didn't get any feedback after the inevitable investigations, whether that car was still sold new or they de-classed it and sold as used i have no idea.

A useful place to look on a hot hatch would be to closely inspect the inner wings and area of the driven wheels in particular, hot rubber burns into the plastic, yes it will come off but the evidence of severe thrashing should be there, same as ingrained mud from off roading is always visible on 4x4's, if the buyer can be bothered to slide under and look.

Usually though hot heads can't help themselves making individual (though most do the same things :-) changes to make their cars appear more sporty, seldom are these cars totally standard.

I would not buy a car with a weird gearbox with my own money, unless it was under a proper maker's warranty for the duration and then i would still be sceptical, due to attempts to shift the blame we read regularly on these pages.

The dual clutch semi-automatic gearboxes were always designed for the performance (and efficiency) market, which is why they started out in high end cars after they appeared in motor racing. What they don't like (the racing ones are the worst and burn out very quickly), just like manual gearboxes, is riding the clutch, but unlike a manual, there's less of a clue as there's no clutch pedal to know you're using it too much on slow speed manouvringcreeping forward in traffic or keeping the car in D rather than N when stopped at a junction/traffic lights/in heavy traffic.

IMHO, people either don't do their homework and/or just get lazy and use them like a TC auto, which they are definitely not. Even worse if you regularly tow. Still, I'm sure some people love doing racing starts all the time!

"....keeping the car in D rather than N when stopped at a junction/traffic lights/in heavy traffic."

If you have, as I do, auto-hold coupled with the parking brake, keeping the DSG in D is effectively being encouraged. Personally I do it only for a short stop, as for any longer stop the brake lights wil be dazzling the person behind. But I suspect most people will leave it in D for long stops too - another reason for not buying a used car with DCT.
