Kia Stinger (2.0) Performance Issue

[Pinkslipp]

I went on a test drive today with the service manger and my idle stop was on the whole time still couldn’t get it to shutter. I don’t think that is it. Mine has been on and off this whole shutter time

Ya, that's what mine had been doing and they can't replicate it, but it's clearly an issue across multiple 2.0's. So far, the turning off the Idle Stop Go function when first starting the car has allowed me to do normal acceleration with no stuttering. It's 2/2 and I'm trying it again in about ~an hour. So hopefully it goes 3/3 and I have an idea of where Kia can start looking into.

That’s great news! Hope they ship the old engine back to S Korea to diagnose what went wrong.

i will ask about that when i get the car back.

 

[Never thought]

Very strange that this is going on. In 2010 I bought a low mileage used 2009 Infiniti G37 sedan. I drove to work one day, tried to accelerate over 55 and the car stuttered, shook, and stalled. I turned it off, then on, and never had the problem again for the other 70k miles I had it. Dealer also couldn’t find anything wrong.

I had issues that sounded much like this in my 2017 Santa Fe Sport 2.0T... same motor. It turned out to tbe the high pressure fuel pump had a defect in the high pressure switch that prevented it from going into high output mode, starving the motor for fuel at wide open throttle. This put the ECU into limp mode resulting in the serious serious power loss.

Turned out I could reproduce the issue by doing a WOT acceleration from a stop up to about 60- 70 MPH, and it would start happening then stay that way until the car was shut off and ignition cycled once or twice.

They replaced the high pressure fuel pump (the switch component is not serviceable on its own,I guess) and this has fixed it.

There were codes that would get thrown when it happened but only sometimes and they weren't relevant tot he actual problem.


Just some food for thought...

Hey guys,

I purchased my Kia Stinger December of last year and around the end of January start of February, my car started stuttering really hard on acceleration or my RPM's would shoot up, but my speed wouldn't really go anywhere (ie, 5000-6000 RPM but it would take like 5 seconds to go from 30-40 merging onto a highway).

I took it back to the dealership where I bought it and they looked at it for a week but couldn't replicate the issue. The did change the oil and there was a recall on two hoses that were leaking that they replaced. I took the car home and didn't have any issue with it for about a month. Now today, (March 14th), I leave for work and make a left hand turn out of my apartment complex and notice halfway through my turn that my car jerks really bad and almost stalls out. My initial thought was that it was my low gas, but I went to the station, filled up, then had the same issue happen again as I left. (I know it's not bad gas because I had just drive ~400 miles on that tank before the issue happened and then it happened again on a brand new tank)

It got worse, when merging onto the highway, the power issue came back and I couldn't get my car to get past 35-40 mph trying to merge onto the highway at 5000-6000 RPM. I've taken my car in 3 times now, and will be taking it a fourth in 2 weeks time. The technicians can't replicate the issue, but my fiancee has seen it and witnessed the stutter issue.

If anyone has any inkling of an idea of what the heck could be happening, it would be amazingly appreciated cause I don't want to have to get a lawyer for lemon law.

I had the exact thing happening to my 2.0. There is a TSB related to the transmission. My dealership was familiar with it, made the repair and it has stopped.
Hope you get it repaired soon, it is dangerous as I almost got in an accident due to this.

My Stinger (2 months old and only 1700 miles) is doing the exact same thing. Studdered Monday and Tuesday Mornings, called the dealer to get it in for service and when I went to drive it to the dealer that night after work I couldn't even get out of the parking lot it was studdering so much that I was afraid to drive it since the car couldn't even get out of its own way. Had it towed to the dealer and they find NOTHING wrong. They couldn't even make it happen again. But for the time being i get to drive a lovely Slow Blue Forte (looks like a blueberry)

If you have the 2.0 there is a TSB out for this. Dealer should be aware but ask them about it. It resolved the same issue for me, happened especially when it was cold out and my car had been sitting for several hours.

That is exactly when mine started it was cold and had been sitting all weekend. I will have to call them today on the TSB since they have had my car for over a week now and still nothing. They keep saying everything keeps coming back perfect and they haven't hear of this happening before. I keep telling them to google it that there seems to be quite a few stingers that are having this problem. Starting to get irritated since I am paying for a stinger but driving a Forte.

Sorry to hear about the issues. Definitely keep us updated on what they say regarding the TSB!

I wonder if they have a trained tech to work on Stingers? At my dealership it’s obvious it’s new and they are learning as they go- to be expected I guess, but one guy seems a little more knowledgeable, although sometimes he’s wrong too in the end.
If it’s still cold where you are in the morning I’d definitely tell them that’s a trigger.

It’s already listed in the TSB board. Sorry I was too lazy to get the number before and couldn’t remember the part. My issue was SA333 AUTO TRANSMISSION FLUID WARMER CONNECTOR. Connector had to be replaced.

Sorry to hear that. well i think my Stinger is worst got it sunday night and went back in the morning to the dealer to give them the spare keys for my trade in, and while i was there might as well get the salesman who i got from to learn the features of the car. So we sat there for 30 minutes the car is running and after that i left the dealer lot, a few minutes later i hear a loud noise coming from the engine and then it stalled on me. I thought it was the battery but it's not called the road side assistance and have it towed back to the dealer. There all shocked to what happen to the car explained to them what happened and service director have it looked, came back next day they talk to me what happen that part of the engine broke and KIA don't want them to tear it down to fixed it. KIA well replace it with a new engine off the assembly line.

Not sure, but you probably win the prize for the first Stinger engine replacement in the U. S.!

hahaha! I know right. Everything is running fine now.

This is the second time I take my car to the dealer for the same noice problem. The first time the said it was a recall and they fixed, but after a month the noice came back again . They said they don’t know from where the noice is coming from, they try everything. Is really bothering me when I’m driving. I’m not enjoying my car any more. I don know what to do

I had had the same issue, with my car . I take it to the dealer and the computer said is ok, but is not happening all the time . I’m afraid to drive my car if feel insecure

So finally today after the Dealership having my car for 17 days it is finally (fingers crossed) fixed. My Stinger was having the studdering on acceleration issue. Only happened after the car sat for awhile and when it was cold. The dealer couldn't recreate the issue (I live in Florida not that many cold days) but after doing every test known to man - a flight data test, fuel test, 5hr graph test and sending all that data to KIA, KIA wanted them to replace the fuel pumps (low pressure & high pressure) of course they didn't have them in stock and had to ground ship them from California. Once they put the low pressure pumps in everything stabilize and to quote the Service Manager "the hoses stopped bouncing around" and apparently now the car drives even better than when i brought it in. He thinks the low pressure fuel pump was starting to go but not bad enough to throw a code yet. Guess we will see. Fingers and toes crossed.

Hope Your Stinger is all good now.

So far so good with the engine. Even had my boss who is a major car lover and races cars drive it yesterday and he said it felt good. Only problem is they gave me my car back dirty and dusty as hell even after they were to do a new car detail. Oh yea and spot/grease marks on my headliner. Going away present for being such again in the ass I guess. Waiting for the service manager to get back from vacation to have it fixed. I have learned to only deal with managers. Not worth talking to anyone else if you want things done. And a call to Kia customer assistance center never hurts too.

Oh and once I got my car into service after a call to the new car sales manager with a loaner car anyone should just keep refusing to take your car back until it's fixed. They would run test after test and sa it it running prefect. I say no, keep going, call Kia customer assistance and complain (the rep called the dealership while we were on the phone) thus forcing them to dig deeper. That is the only way they found my problem. No codes had been thrown yet but something was wrong and the only way to find it was the 5hr graph test and the flight recording test with results sent to Kia. Once they found the problem they still offered to have the car washed and ready for me to pick up until the parts come in. Umm yea NO. Apparently my car was the first Stinger they sold and lucky for me the first Stinger in service. My advise to all is be aggressive, be force full, don't accept everything looks good because let's be honest this car is to new and no one really knows. But an owner knows when something is wrong their car.

I seriously doubt that KIA had to ship the fuel pumps by ground all of the way from California to Florida.

Someone, either KIA or your dealer, was trying to save a few bucks while forcing you to wait several extra days to get your Stinger fixed. That's simply short-sighted, idiotic BS!!!

This is another example of how KIA and its dealers need to start doing a better job of serving their Stinger customers.
