my 2022 Seltos (1.6 ltr Turbo) with 900 miles bogs down when leaving a stop sign or other complete stop. Once the car is moving the engine performs fine but there is a moment when it appears to hiccup, lag, or just not want to move .

Normally I turn off the stop/start engine function so the engine does not turn off at a traffic light or stop sign, but on occasions when i haven't turned it off, it feels the same on the restart/take off, with a slight pause before moving.

I also notice a lag when i am going uphill, it almost seems as if the car is not getting fuel and then it all kicks in at once and the car lurches forward. Has anyone else ever experienced anything like this? and what was the fix?

Sounds like regular 'turbo lag' to me - the delay. Not thrilled with the tran/engine combination myself, but it seems there are less engine/transmission problems with the turbo, so there's that... Some people would suggest you try Sport mode for some of your observations...but it seems a little to skittish to me in that mode.....

Hi there, This used to happen to me quite often, until I realised it was me causing the issue.
I used to have a regular auto slush-box type car and had the habit of keeping my left foot on the brake at a stop and then releasing the break just as I accelerated with the right foot. Dont do this on a DCT !!!. The computer knows the break pedal is depressed and that youre also trying to accelerate....confusion strikes.
Once you release the break pedal properly the car will move sluggishly to start with. If the car went straight to normal operation, it would lurch forward and likely hit into whatever's in front.
Cheers

Thanks. I was told it was the spooling of the turbo. Still had no clue but it annoys me since I live in a very hilly area. Glad to know it’s not just me.

Thanks. I don’t left foot brake but I do use the auto hold feature which causes the lag as well. The lag is just something I will learn to deal with over time.

I HATE the SXTurbo (Can). I understand the lag you are talking about, as I have it all the time. Sometimes it’s laggier than others, as if not enough gas is getting through. Especially dangerous when pulling onto busy road/highway, cannot get up to speed right away.

Then there’s the “bucking,” as if there was a brake holding it bag, then “Pop!” it jumps ahead quickly.

I have a 2021 Seltos with the Turbo. Years ago I had an Optima Turbo which did not have the same issues.

Some say it’s turbo lag, others a transmission issue. All I know is that I’m glad I leased, and I’m already looking forward to giving this car back in 3yrs 1mo. (But who’s counting?)

Thanks! That is exactly what I experience. Using sport mode helps but it seems to jump forward faster than during normal mode.

This sounds more like clutch engagement time from the DCT rather than turbo lag. Even if you floor it the vehicle is soft off the line because it is protecting the clutch from excessive wear and tear. This pretty much goes hand in hand with their 10 year powertrain warranty IMO. They're going to program the transmission to be gentle on itself so they don't have to replace clutches on older Seltos that are still barely in warranty. The often jerky and lurchy starts are the same deal. If you want a smooth gradual takeoff you have to spend more time slipping the clutch which produces more wear, more friction and more heat. All of this shortens clutch life, so they sacrifice refinement in order to ensure the longevity of the transmission.

This is why you are seeing the more expensive Hyundai/Kia vehicles with DCT trannies switching over to a wet clutch setup. Once it has its own source of cooling/lubrication they can take more measures to improve refinement without the clutches getting too hot, but the Seltos is an entry level vehicle with a dry style clutch so we have to live with the lack of refinement.
