Bought two 2019 Sorento SXLs and both have same problem with stumbling hesitation between 25-55 mph when accelerating or going up inclines. Dealer says it’s a solenoid in new 8 speed tranny and all do it. Very frustrating for intown driving. Called Kia and they just referred me back to dealer. Love the car other than that. 26.5 mpg on 2600 mike trip from VA to FL and back. Mostly I95 at 75-80 mph.
Skyking
Lordy, I hope we're not about to see the fiasco of the early 2010 Hyundai tranny solenoid repeated here.
Rumor back then (and that's all it was) was that poor/lack of anodization of aluminum solenoid part caused it to stick. Some could be beaten into submission with a code change that presumably hammered the solenoid a couple of times rather than just a single enable signal. Some had to be replaced.

Are you driving in ECO mode? or Normal? i found that this hesitation was greatest with the ECO mode and i'd press down on the accelerator even more. i dont see it as often in Normal which i have switched to now. my assumption is that if i drove in Sport i wouldnt see this at all but then I'm not willing to trade fuel economy for that. instead i switch to manual at that point and then back to auto when the automatic transmission can manage on its own
Yep, every unanswered problem is always described by auto companies as 'normal operation'. For them to try dismissing this by saying 'they all do it' is astonishing, considering that Hyundai/KIA began working on this 8 speeder in 2012 in order to create the smoothest possible shifting transmission under all conditions. And what does 'it's a solenoid' mean exactly? Are they saying that one of the solenoids is defective? Could it mean that the factory put an extra solenoid in, or left one out by mistake? Or perhaps 'solenoid' is just the word of choice to throw out to BS the owner.
My first suspect would be a mistake in the engine/transmission management computer programming of these vehicles, which of course is JMO. But whatever the actual problem is, they better quickly move beyond 'they all do it' and get it fixed, because Hyundai/KIA already has way more than their fair share of black eyes.
I've got the same problem on my 2017 LX Sorrento. Bought the car used w/ 20,000 miles on it, it now has 32K on it and if I had noticed this stumbling problem I might not have bought it. It was really bad till I disconnected the battery for an hour to reset the transmission shift points. It seems maybe 50% better now, still bugs me though. Strange both your Sorrentos have the same problem, can't believe others aren't seeing it.
More tranny woes
Had vehicle to a different dealer and was told the stumbling hesitation is because the 8 speed is a dual clutch transmission and to check back in six months because Kia will Probably have a software update for transmission. Can’t find any info that it’s a dual clutch tranny!!

Not sure why a dual clutch automatic would cause a hesitation, maybe just the opposite. Generally accepted that a true dual clutch auto outshifts any manual or automatic transmission ever made. Not aware that the 8 speed was such an animal. My LX V6 6spd auto is smooth as butter in normal and sport mode, not so much in eco. Eco seems to hold on to every gear until the bitter end when trying to accelerate so that the car feels like it's hesitating and then finally does the downshift and kicks back on for a few seconds and, if you are still trying to accelerate, will go through the whole process again. Other than kicking it all the way to the floor, I think Eco mode is dangerously slow to downshift. It might return another mpg but I wish I could permanently lock it out on my vehicle. And I wish the car would stay in sport mode once turned off and back on - it does it in eco mode so you know it's just a programming issue.
If the OP's car is doing it in all modes then I suspect a software update with be forthcoming in a fairly short period of time - this is a bread and butter vehicle for Kia, it absolutely has to be right.

It was all my poor parents could afford to buy a used '16 LX with 17k miles last year. lol. My 2019 sxl exhibits a surge/ chug at 25 - 35 mph. It is similar to attempting to drive in 4th or 5th gear when driving at lower speeds. Moving the automatic shift lever to manual mode shows vehicle already in 5th. I think this is a software issue that could easily be resolved for drivability. Obviously the quick upshift is to help potentially improve gas mileage. I am sure the standard response is “ they all do it”. However, that is not an acceptable answer. I will pursue with my dealer and attempt to have a District Service Manager review with me. I only have 1500 miles and have not had my first service yet.
Dual clutch ! I wish.
My Sorento is not showing any shifting / lugging. Only at 300 miles so the software may still have the trans in break-in mode...
And I avoid eco mode
Noticed that highway cruising in sport mode leaves it in 6 rather than ever upshifting to 8.

2019 SX hesitation issue
I have a 2019 SX and a search for this hesitation issue landed me here. For me, it's most noticeable when you are accelerating from between 5 and 15mph. I live near a traffic circle and you merge at a slow speed then accelerate and it's very noticible. When I hit the gas, the car "stumbles" making you think it won't accelerate or is stalling. Only lasts a split-second but every time it make your heart jump a little. I'll try it in different mode since it usually just stays in Eco. Have to take it to dealer soon for oil change and I'll have them take a look. Thought it was just me so thanks for posting. Let you know if I get an update.

I have a new EX V6. There is a little chugging at those speeds in ECO mode, and Smart too. I just leave it in Comfort.
Keep in mind, the torque peak is at 3500 RPM, so at lower speeds and gears it has less torque than the turbo for example, which peaks at 1700 RPM.
So the simple answer is probably downshift, or give it more gas pedal, and stay out of ECO except on the highway.
I had the same experience in my 2016 SX. I just changed my driving style to make it work.
Remember, this is a 4000 pound plus vehicle, it will never perform like a Hemi charger.
But since I am used to it, it really does not bother me. I just know when to give it more gas and the car responds properly.

Solved, sort of.
Turn off auto climate control (turn off the AC).
You will feel much better acceleration and smoother power.
The 2019 has a different system than my old 2016. On that one, the AC light would rarely come on unless I went all the way down to LOW.
On the new one, at 55 degrees outside and 67 on the dial, the AC shows on.
I had a Honda Civic, on which the AC SUCKED. BUT, on acceleration the compressor would shut off, sending max power to the wheels.
Kia could do this with software probably, but be careful what you wish for.
The Sorento has great AC. I would not mess with it.
Once the weather gets cold and you can run with heat and not AC I think you will see the difference in both performance and MPG.

I believe Kia/Hyundai replaced the 3.5L v6 with the 3.3L sometime around 2014/15 and it has had pretty much the same HP/torgue rating since it's introduction. With only 252 lb-ft at a rather lofty 5300 rpm, it'll be good to have all those gears.
My 19EX V6 exhibits the same miss/hesitation/stumble that most everyone else seems to notice. On mine it's most noticeable for a while just after starting the engine and from about 1000 to 2000 rpm. However, it seems to smooth out a lot after having a good chance to reach normal operating temperature, about 15 - 20 minutes, even though the temp. gauge will show normal op. temp, way earlier. And it always seems less noticeable in SPORT mode. Because of that, I just wonder if it might not have something to do with different engine operation/mapping in the different drive modes, especially in SPORT. I'll have it checked at the first oil change in about 8-10 weeks.
BTW, if anyone is interested in fairly detailed specifications of their Sorento, or most any other car for that matter, check out this link: http://www.automobile-catalog.com/make/kia_usa/sorento_3gen_na/sorento_3_2_4wd/2019.html

I've only noticed it (just barely perceptible) on the very first upshift after going into Drive after backing out of the driveway.
Interesting to see if the coming cooler weather makes it more noticeable.

2019 Kia Sorento SXL V6 engine stumbles
I have this issue as well. Going back to Kia Dealer tomorrow for the second time. My symptoms and diagnosis below:
• The engine stumbles (misfires/vibrates) on light acceleration since delivery when the engine is not fully hot and up to temperature, and continues to do so now with 2850 miles on the engine.
• On the advice of the service manager, only Chevron fuel has been used for the last 2000 miles.
• The car has recently gone 1500 highway miles at varying engine RPMs
• As an experiment 2 tanks of mid grade 89 octane fuel were used.
• None of the above has altered the cold engine stumbling/ vibration at light acceleration.
• The stumbling problem goes away when the outside air temperature in below 50 oF.
• This is the second complaint about this issue with this vehicle.
• This issue negatively affect the cold engine drivability of the vehicle

Hesitation Issue
I purchase a 2019 LX 3.3 lt in Nov; & it was OK until it had about 800 km & it stared to do the same thing, does not matter what mode I had it in, it is noticeable even going up inclines .I complain to the Kia Canada there said that they have no issue/info; on the problem & referred me back to the dealer & said that any diagnostic work would be my responsible $$$ so I file a complaint with transport Canada saying that it could become a safety problem they have not reply back as yet, also I notice on the U.S. Gov; NASTA there are 5 complaints filed about the same issue..so let keep posting any new info; that my come up about this issue

If it's not tripping a CEL then take a code reader and see if there is a pending code for a misfire. If not, it's not really misfiring, just stumbling under acceleration. I'm sure that Kia is working on a software solution since that should be all it takes. It sounds like the 2019 w/8 speed is trying to momentarily retard the timing for the shift and getting it wrong. Very simple map change for someone to write and send out to the dealers but they may be waiting until they've gotten enough little annoyances to clear up and then do them all at once.
