The other part to this confusion is that some people have reported their tires being over inflated when they take delivery. There may be some people who notice a vibration just due to dealers not adjusting tire pressure. It's not the same vibration that is being discussed related to the AWD driveshaft. If someone could recreate the condition, record it and post a video with the water bottle on the dashboard or something that could be a reference for other AWD owners that might help. Just a thought. I'd be happy to recreate the same test in a FWD as a comparison if it would help.

If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

I would think the water bottle in a cup holder would be better since the vibration is usually felt at the driver's and passenger's seats. The floorboard would be great ass long ass it was water and nothing else.
Even discount tire over inflates the air so we always let about 5 lbs out and bring it down to about 33.

@Bev here is my issue - the Driveshaft places near me specialize in just balance, repair, and manufacturing the driveshafts. They don't have the lifts, or the proper insurance to do all of that and the actual repair as well. They work directly with mechanics.
If I or a mechanic take off the driveshaft and take it to an expert then Kia is going to point the finger at me...I'm all about expert reports but I'm having trouble getting an expert to properly inspect said issue without voiding my warranty.
In conclusion - if Kia never agrees to remove that driveshaft (and they are the only ones that can), I will have to live with the problem which is nuts! Possibly not being able to get it fixed or get an expert to analyze it...talk about a racket!

I don't know where you live but surely there is someone within a 100-mile range that you could book an appointment and wait for it.

This looks very useful and powerful. Has good reviews online and a mechanics forum I was on...
I'd have to cough up $399 to go after Goliath with legit data. Y'all want to setup a GoFundMe for me? Haha just kidding!
I emailed the owner of the app and asked if he could help a brother out with a one time use token or something just to get one report...let's see...

That looks like an awesome program. Overall, the location of the vibration could not be a window mount in order to diagnose the Tellie situation.
Are there cables that could be attached under the driver and passenger's seat? Also, a tire road force test should be performed prior to investing in this program.
I surely see how that could work.
Hats off to the developer.

Very interesting app. Of course, I did read one review (screenshot below) on what turned out to be a drive shaft problem that was not identified by the app. I wouldn't necessarily expect the app to be perfect, but that is a lot of money to shell out for something that may not help solve the problem in the end. It seems like the price point is specifically geared to those who either reached their wits end trying to solve a vibration problem or someone who would generate income from using it. I wouldn't consider this until I exhausted my dealer and third party professional options. In the end, for most of us, this would only be a data point that would hopefully lead to convincing someone else that there is an actual problem.

This video shows how you can measure driveshaft vibrations. Go to 34.30

How will Kia know the drive shaft has been removed, unless you tell them? (put match marks on it first, remove it, test it, replace it using the match marks, erase the match marks)
If you have it tested and its not the cause, you have eliminated a possible cause and can now concentrate on other possible causes!!
If it is the vibration cause, go to KIA and tell them you want the driveshaft tested, don't tell them you already know what the result will be. If they refuse write them a letter informing them that if they do not test the drive shaft you will have it tested by a 3rd party, request a reply to your letter within 2 weeks, state in the letter failure to reply to your letter is equivalent to refusing to test the drive shaft. Send the letter using Certified Mail Return Receipt Requested, this gives you a receipt showing they received and signed for the letter.
If they decide to test great, they should achieve the same result as the 3rd party and the issue should be resolved; if they don't test - take them to small claims court, bring the letter, the returned receipt, and most importantly the 3rd party tester or an affidavit from the 3rd party tester stating his expertise and the results of the experts drive shaft test (i.e. unbalanced or bent or whatever is causing the vibration.)
In small claims sue for cost of repair if it is completed by the 3rd party, the 3rd party testing costs, court filing fees, and anything else directly related to resolving the issue.
This is a shitty pain in the ass way to do things but living with it is not the correct answer. I have found certified letters gets attention, usually because the receiver knows it means a record that can be used in court was created.
Remember the dealer is a business, buying the car was a business contract and the warranty is part of that contract. If you give the dealer "provable" notice (the letter) and they don't perform they have violated the warranty part of the contract and you have the right to a remedy. Bottom line - this is business contract dispute, and remedies are available outside the dealership if necessary.
Hopefully they respond to the letter and resolve the issue.

That’s a lot of money for an App vs finding an expert that can produce a legit report for the same or less.
I think this thread has the potential to become a megathread. My recommendation is one of the site admins should start a new thread with the subject aimed at AWD owners and if possible add a poll at the top asking if they feel excessive vibration or not. Then have them post at what speeds they feel it is excessive. The the first couple posts could even be aimed a common things to mitigate like air pressure or other things that have been reported as Kia Techline remediation steps.
Then perhaps simple and free instructions like fill a standard clear water bottle with juice or some colored water up to a certain visible level and place it in a specific cup holder. Find a relatively flat and safe stretch of road while recording the water bottle as speed is increased and announce or note in the video the speed when the vibration becomes “too much”. I would think if the vibration is as noticeable as some expect the resulting comparison videos should make it obvious.
Unfortunately, if it is a design problem I don’t think it’s going to be as easy as look underneath to see if the U joint or one of the 7 bolts are bent or cracked. The real decider will be if people with more vibration have a 5%+ variance in the shaft when comparing front to rear and then if people with less noticeable vibration are closer to level or 0%.
I think the only true non-Kia sponsored testing would have to be multiple Telluride owners running the same comparison test on the same drag strip at the same with same tire pressure and weight for cargo and documenting the trim differences. It would be comparing at least 2 AWDs of the same trim one with the reported vibration and one without then perhaps a comparable FWD.
Short of taking two AWDs, one with the excessive vibration issue and one with to the same independent 3rd party driveshaft specialist for diagnosis, I can’t think of something any better or easier than water bottle recordings.

All solid points - I need to take a deep breath and put on my contract law experience into place. I'm not a lawyer but play one with contractual wordings in my job.
This is a great plan - Kia is wise though...they put markings on the Driveshaft for matching purposes...if I don't put it back together absolutely perfect with their markings I'll be out of luck...

If it's a design problem it should be present in all similar equipped Tellurides as the design is identical and it's not present in all similar equipped Telly's. Therefore it I do not believe its a design issue, its much more likely a part or assembly issue, there are plenty of parts in the drive train that can cause a vibration. Appropriate trouble shooting should be able to narrow the field of possible causes rather quickly, I don't think Kia dealers have the knowledge or skills necessary to perform an adequate cause analysis to determine the actual cause.

The drive shaft should be able to be put back perfectly without issue. Need to be careful not to damage any fasteners, if you do buy new factory ones (from the web) and replace them so there are no telltale marks (rounded or scratched bolts and nuts).
Besides the vibration issue is already identified in a warranty claim with Kia; How can Kia claim you caused it by removing the drive shaft AFTER it was reported and put into their system. Its provable that cause occurred before drive shaft removal.
______________________________
I posted an independent diagnosis from a Driveshaft Specialist that has been in business for several years and highly rated by individuals and businesses. It did show a 5% difference at the front of the driveshaft. That would make it a design problem. I am sure it's the same thing on all the AWD Tellies but unless they have a similar independent diagnosis, Kia or any attorney will consider it.
If you're waiting for Kia to diagnose the problem, take you a rocking chair to the dealer and your application to apply for your Social Security because the only way Kia is going to admit the problem is in a class-action suit.
