New 2022 SX Xline prestige shakes when driving.

Question for the 21 and 22 sx xline owners, in my new sorento there is a very minoot wobble/shake/bounce/jiggle when driving at all speed, less at lower speed and more at higher speed. Mostly felt from the floor board, steering wheel does not have any movement. The shake can be seen on 2nd row seats on rear view mirror. Especially noticible on smooth/new roads. Tires were road forced and force matched, checked for radial and lateral run out on wheels and tires, wheels were rotated several times. Wheel and tires are fine. Had several people drive the car, car people notice the slight shake. Others not so much. Dealer service manager test drove the car with me and claimed he does not notice anything out of normal. They did not have anything to compare it with. They have another sx xline coming in in two weeks, will test drive it back to back with mine.

Sorry, left the question part out from OP. Did you all noticed any shimmy/shake when driving. Or is it just a nature of the car. Its very minoot but enough to jiggle all non lean parts of the body.
I suggest you have a 4-wheel alignment and tire balance check at the dealership if it is very new. Sounds initially like an out of balance tire to be honest (simple to fix).

Thats what i thought too initially, dealer thinks it is a non issue. Thats why i had a local discount tire shop rebalance and rotate tires. Tire shop said wheels and tires are not the problem. Shaking almost feels like a tire has a flat spot after being parked for a while or a cv axle/driveshaft imbalanse. I would like to know if others have that issue or not before i start chasing a problem that may or may not exist.

Hmm. I haven't had an issue like that. Did they check the 4-wheel alignment as well?? Did the tire shop look for any flat spots on the tires? Not unheard of with new tires (especially OEM tires) having an issue like that.
Tire shop checked tires and wheels, they are not the problem. Dealer thinks there is no problem with the way car drives. Thay want to test drive the car with similar model back to back before doing anything or calling me crazy.

I've noticed this occasionally while driving with nobody else in the front passenger seat. It'll vibrate on certain road surfaces. It's very subtle, and I don't notice any vibrations on the drivers seat. When someone is seated they can't tell. It doesn't really bother me so I haven't done anything about it.
Some shops use a sophisticated wheel/tire balancer that simulates contact with the road. It's called Road Force Balancing. Check it out. I really miss Pat Goss!

Update... Kia dealer received SX AWD. Car had 10-12 mile PDI(pre delivery inspection) already done. Service manager and I test drove it for another 10 miles or so. It had that shake/wobble just as bad as my sorento. Service manager did notice it immediately, said it is just a nature of the car. I also test drove one customers SX Xline with 1k miles on it. Shake/wobble was there as well, but a lot less noticable. I guess just have to learn how to live with it now.

I have a relatively new '22 SX-P, X-Line (1656 miles) and I think even though yours is not a prestige, mechanically your car and mine would be identical. 20 inch wheels, right?

I DO NOT have any shakes or wobbles at any speed (at least up to 80 - haven't driven any faster). Therefore, I think the service manager is blowing smoke. Yes, you happened upon a second car with the same problem as yours, but IMO, that falls under the "as luck would have it" category. I can almost guarantee you that KIA headquarters would not be singing the same tune, nor would they want that "just the nature of the car" to become accepted throughout the land.

You need to elevate this problem to a higher level. Find out if there is a District Manager (if such a thing exists) and take your car to him. Good luck!

Sorry, my sorento is SX-P Xline with rust interior. Yes, SX AWD has same mechanical specs, same drivetrain, suspension and wheel/tire. Thats why service manager wanted aples to apples comparison. You are correct, it is not normal. I have owned 7 different kia cars in the past 10 years. Last ones are 22 carnival SX-P and sorento SX-P. Non of them had this problem except for the new Sorento. At speeds 75 and up car gets bad jitters. Since the car has already been at local Discount tire shop several times for rebalance, road force/force matching and rotation, they eliminated wheels and tires. Unfortunately they don't do any diagnostics on drivetrain or suspension parts. They advised to have it looked by dealer under warranty, but dealer wont touch it saying it is a non issue. Even if i paid the dealer for diagnostics, they are not willing to "chase a problem that does not exist". I will follow your advice and try to escalate to corporate level, see if they try to resolve.

It is important to find someone from the corporate level that is within driving distance of you, as I don't think you will get any positive results without one of them actually riding in your car. I see you are in Florida -- hopefully you are close to someone high up.

If, as we now suspect, it is a not-so-rare problem among new '22 owners, you will be doing a yeoman's job in pursuing this, as it may actually pay off -- not just for you - but hundreds of others, if they send down an edict to all KIA service centers. Once they find the true problem, it might even result in a safety recall.
This is a very bizarre issue. Mine is smooth as silk - always. I wouldn't give in. Take it to a Hyundai dealer and kindly schmooze them into taking it for a test drive with you. See what they say. Sometimes a peer can easily get results that a customer can't very easily. Hyundai owns a majority of Kia - so they can pressure them to fix it. Plus it would be embarrassing if the Kia shop said they couldn't fix the issue to a Hyundai shop. :) Just my $.02 .

FWIW: I'm had mine up to 85MPH and no shakes/wobble that I can tell have happened. YMMV.

21 XLine, Mine up to 130 mph no problems.
If it were me, I would take it two differnt KIA dealerships or as someone else suggested a Hyundai delership.

Did you get this fixed? I'm having the same issue and my car has been with the dealer three times already. The dealer is saying that the car is fine, although I can still feel the judder/vibration through the seat and floor. Most evident at speeds over 60mph and I can see the middle seat shaking. This is very annoying. I've had both winter and summer tires rebalanced and checked, both are fine.

I just got back from a trip to Durham, NC. My Sorento was smooth as silk. Not sure what could be up with your suspension.
Have them check for tire separation..

I would not accept, "It is the nature of the car"

No, I could not figure it out. It was not the tires, it did it with stock ones, did it with falken wildpeak at trail and pirelli scorpion as plus 3. Many balancing and road forcing with no luck. It was not the wheels, checked the wheels without the tires on a balancer for runout with dial indicator, all whithin spec. All thanks to a local discount tire store manager who worked with me. I even bought a $100 NVH app on my phone to check order of vibrations. Test drove the car for couple of thausand miles on the smoothest roads I could find. Gor mixed results, 1st and 2nd order of tire speed related vibration, driveshaft and engine speed related vibration. Another dead end. Then local kia service manager and I test drove brand new same config sorento back to back with mine. Shockingly the new one they had on the lot had the same vibration problem, they called it "nature of the car". I met a guy at the window tinting place that bought the same config sorento in aruba green the same day I did mine. So we test drove his back to back with mine, his was smooth with no problems. Next steps would have been ask that guy come to the kia service and let the manager test drive. Another step would have been checking the hub, axle and driveshaft. BUT, along the way I started getting "check transmission" message when the car started. Long story short, transmission failed and was replaced at around 6k miles(most of the miles being test drives after tire changing and road force balancing). So I had to claim a lemon and get rid of it. Hope you can figure it out, or learn to ignore and live with it.

One thing I forgot to add. I changed the wheels and tires between my wifes 2022 Carnival. Sorento drove smoother with Carnival wheels and tires. Carnival started vibrating a little with Sorento wheel set. Did the same with my brothers Telluride. Same result. Told what happened to the discount tire manager, he said he will order some 5 finger lug centric lock plate for their balancer, to see if the hub vs lug centric balancing would show the runout. Anyways, after the transmission problems started just gave up on the vibration problem.
