Car stops and hesitates around corners

[Gus23J]

Not too sure if this is the right place for this discussion, but does anybody else have a problem with their car basically hesitating to a crawl or stop when going around a corner from a stop? It seems to only happen over a rougher road like when you would normally see the traction control kick in, but I never see the actual traction control light. I hope this makes sense, and if anyone is also having this happen, or knows of a fix, I’d appreciate it. I have an AWD 18 premium with the 2.0 engine.

Thanks!

Are you braking with your left foot?

Nope, right foot for the gas and brake and never at the same time.

What tires you got on it?

Yes, mine does this too. Leaving my kids daycare the transition onto the main road has a small crest and it causes the car to cut power.

I’m on 285 rears and it’s not actually losing traction. It’s almost like the car has some kind of yaw sensor that predicts you will lose traction and cuts power before you actually do.

Yup I experience this too on one corner on my way to work every morning. Its a 90degree corner from a stop onto a steep hill with very rough pavement.

I will probably never notice this, because on any uneven surface, especially while turning, I drive sedately. These conditions are not, imho, the time to hit the power. I only get on the go pedal when the road is good.

Nannys kicking in because of wheel spin (loss of pavement contact) between bumps when accelerating hard.

For me it happens under light normal acceleration.

Does this still happen to you with traction control turned off? Do you have lowering springs and/or upgraded sway bars. If you have a stock suspension setup, maybe the infamous rear end float is exacerbating wheel spin and kicking in the traction control. Plus, turning a 90 degree corner onto a steep hill with very rough pavement, even under moderate to light acceleration, might cause enough wheel spin to activate traction control and cut power. Wish the nannies in the Stinger were not as sensitive as they are.

I have a stock suspension other than an upgraded Eibach rear sway bar, but this issue was prior to that install. It isnt really a big issue for me, its only for a second and its obviously because the pavement is in such bad shape. I also have 225 45r winter tires on right now so again another reason I'm not all that concerned.

Sounds like that's it then. It happens to me to when I'm pulling out of my driveway and give it a good bit of gas to get out in front of a car. Power cut and hesitation. Come on smooth and it doesnt happen. I think the awd control system does a lot of work to keep the car on the road. I drove it around with traction and stability turned off and I find it easily breaks traction without much gas at all. Quite a fun time. Cant wait for summer to be an absolute hooligan.

I've noticed the same problem and it has easily become the thing that bothers me most about the car. My office is on a fairly busy 4 lane road with no center turn lane. When I leave to go home for the day, I need to turn left out of the driveway. It's a bit of a bump and it almost always initiates the TC and cuts power for a good full second if I leave on anything more than a roll. In busy rush hour, I've begun to disable the TC if the road is busy. I literally can't risk the coasting across lanes until power comes back.

 

[MerlintheMad]

"A good full second (or two)", aha. Well, I probably do see this happen, but it feels normal to me: as if the car is "gathering" its legs under itself before taking off. I expect a bit of stall now and again when the road surface is obviously playing games with all four tires.

Try downshifting with paddle before turning in "tight situation" Use shifter to return to drive, at least it works for me. Really scary when you are dead in the water so to speak and traffic is coming at you. Only seems to be a problem in a tight turn? Seems to be more a problem for me in "comfort" mode.

Does turning off the TC resolve the problem?

Correct. Just tap the center console button to turn off. Get into traffic and up to speed and turn it back on. Kinda annoying but at least it's easy to toggle.

It just happens to me all the time with the crap roads here. I'd have to treat it like the ignition auto-shut off and turn both off every time I start the car.

You want both traction and stability control off, you have to hold the button down for c. five seconds, and get two beeps.

From my experience you just need to disable the TC and not stability control, at least for turning+accelerating over a bumpy surface.

I haven't experienced this kind of power cutout in other cars with fancy traction systems. Especially with AWD systems but even many FWD or RWD platforms which you would assume wouldn't work as well.. Most of the situations I have had it happen in the stinger, a single wheel has compromised traction, i.e. small pothole or pavement transition. It is and only has been while some steering input is applied, like turning a corner. Ironically, this is usually the most important time someone needs to get up and go without delay. I haven't read up on how the front, rear and center diffs on this car are setup but I know many other AWD platforms would maintain power through at least the other set of wheels to keep power to the ground.

Maybe KIA will offer an update at some point to reduce the power cut time or to ignore a single wheel speed sensor upon turning within a larger window of the others....
