GT2 went into Limp Mode at highway Speed

[jmnaz30]

Was driving at about 65 MPH, car shuttered Solid Check Engine light came on slowed to 20 MPH. was able to get it off the highway. When stopped it was idling roughly. Turned off, started back up fine smooth idling. Called Roadside assistance, its at dealer now. Has 15400 miles on it no issues with car up to this point.

That sucks, guessing fouled coiled pack(s) causing misfires. Let us know what the dealer says.

Will do..

Sorry to hear this. Hope it is something simple!

At least the Check Engine light was not flashing. I'm now in a Hyundai Kona Loaner (LOL) Why are us Kia Owners treated like the step Children and Genesis Owners Get BMW type of care, just saying.

Hey, at least the Kona's aren't too bad! I hear you on being treated like step-children though. They had me in a Ford Fusion Hybrid, Dodge Durango, and a Nissan Frontier while my Stinger was in the shop for various things the first two months. All of those nothing like the vehicle I had just purchased.

If it is coil packs, they should have you back in the road in a day or two. There was a TSB about that, so most service centers probably have the coils and plugs on site.

 

[jmnaz30]

I did not see that TSB, I will look love my car.

 

[bal]

I wish I can remember what that TSB was under, having trouble finding it as well. Perhaps it's internal only and I saw it on Kia Techinfo (Kia Global Information System (KGIS))

The suggested remediation from Kia Techline was replacing both coil packs and all plugs. If you happened to read the OBDII code, it would have been P003* if it's the same issue.

From the picture, I see you're a neighbor of mine

Hopefully you took your car to Earnhardt Kia, they do seem to have the best service dept. of all Kia dealers in the valley.

 

[jmnaz30]

Ok thank you for the info, no call back yet from dealer, will keep this in my back pocket.

 

[Kamauxx]

I've never seen anything about a TSB for coil packs. That would have been heavily discussed here if it were so.

If it is the coil packs would the idling issue have gone away with a restart? I thought it would be more persistent...

Hopefully, the codes are still present when the dealer does their diagnostic checks. If it's running like normal and not throwing a code they might just give it back and say they were unable to replicate the issue.

Oo! Black rims. On a Silky silver.

 

[jmnaz30]

The car so far is running normally. It is still at the dealer, I do not have the code yet but it had something to do with the head, cylinder and Cam. So basically the sensor read something to keep what it thought was Piston and heads knocking into each other. I know this is not technical, but I am not technical LOL. So the codes it threw up stored, but after I initially restarted it it was fine. The dealer (Tempe Kia) in Arizona seems to be doing everything right. I will advise on monday.

Any update? Happened to my 2022 GT1 this past weekend

Frustrating, how many members hit and run on the forum. We turn blue holding our collective breaths for updated information.

You said: Christmas tree lit dash then nothing?

The thing that impresses the longer I own this car is the vast complexity of cars today. Any once-off can be explained by that fact. Is your incident a once-off?

I can repeat an anecdote of my own. In well over three and a half years, I have seen exactly one CEL, c. two months back. This was after several weeks of a new "shudder/stutter" when I would accelerate vigorously in manual gate. I have decided that my driving style changed, not the car. When I return to how I used to drive, never engaging the kickdown switch (for two years and more I did not even know it existed or had a name, heh!), and finding turbo boost under half-throttle or thereabouts quite sufficient acceleration for all my needs, I never feel a stutter/hesitation in the initial acceleration. Also, virtually the entire ownership, I have used the paddle shifters. Since the stuttering manifested under accel demand, I have studied what causes it, and I'm thinking that it is my more vigorous driving style causing a lugging of the engine in manual gate. When I back off to a more "civilized" throttle use, it never happens. When I set up a launch control properly it has not happened. When I use Sport mode and let the car shift for itself it does not happen.

So, complexity plus driver input can cause (not) funny things to occur. Aside from that, I can only say, hopefully your problem is a once-off. If not (and likely not, if you threw several codes that stored), hopefully by now Kia technicians know what is most likely to look for. (And it looks like you are "in house" and if anyone will get top treatment it should be you. )

I'm not noticed the shuttering you describe Merlin, but I do notice that when I get on the accelerator and quickly release, the car can seem momentarily confused about what to do. I think this is entirely a programming issue (modern electronics - hurray!). If I'm into the accelerator long enough, it kicks the car into Sport mode and holds revs. If it's for too brief a period of time, the car thinks it needs to go into Sport but doesn't quite do the swap to that map/programming, or just as it's adjusting on the fly, then has to drop back to the default programming for eco or comfort.

Relating this back to your post, throwing it into manual mode based on the car being best used in the predetermined/programmed settings means you're throwing a lot of possible outcomes at it to adjust on the fly, more so than if it had a more predictable range of inputs and outputs to work with.

I'd think the best use case for paddle shifting would be while in Sport mode with revs being held and throttle response maxxed out. Otherwise the car has to recognize to switch to a particular drive mode based on inputs, then have sudden gear change inputs to calibrate with throttle inputs versus usually only having to concern itself with throttle inputs and doing the shifting at predetermined points. This is why most reviewers/bloggers who spend time with modern cars end up concluding that leaving the transmission alone/not using the paddle shifters is best. Only true sport cars where the paddles are expected to be used (at the track) are the vehicles where the programming seems to be adaptable enough in real time to allow the manual experience to be seamless. Can imagine getting all that dialed in takes a lot more engineering and testing time, which we'll have to forgive Kia for not seeing as valuable for a car not intended to be tracked.

That was an interesting read. I agree that the paddle shifters toss in an added factor that the programming of the various drive modes has to contend with. "Confusion" is a good word here. While I was driving far below capacity (easily the first two years of ownership), my use of the paddle shifters never posed any problem. Now when I stand on it, I'm better served to just let the trans pick the gear.

I'm sure that Kia included the paddle shifters more as a feature to point to as cool (along with the performance gauges), rather than functional in a necessity sense for max performance. The first time I came across this was actually in the promo book, in the Nürburgring chapter. The writer followed a "Ringmeister extraordinaire Dirk Schoysman" around the track, and right away discovered that the paddle shifters were not as efficient as letting Sport mode do the selecting. "Yes, you can pull back on the paddle shifters to manage the 8-speed automatic's shifts, but you quickly find out the faster option is letting the intuitive transmission make decisions for itself -". So, months before I got a Stinger I had that advice in mind, but still wanted to engage with the driving experience as much as possible. I still do. But now if I'm going to do any rapid accelerations (short of kickdown switch) I'll try and be in Sport mode for that. I already satisfied myself that WOT is the same in all drive modes. But how often can WOT be the most useful thing to do?

I bought my Stinger from Tempe Kia, their service dept seems to have things together. Although Horne Kia is closest to my house, and their service dept seems to have car modifying enthusiasts there.

Interesting take, Merlin. Thanks for sharing!

The only times I find myself using the paddles is the rare times that I am on the highway in sport mode and want to shift into 8th, and when I'm on a good back road and I can tell that I'll be in the wrong gear coming out of the corner.
