Purchased a brand-new 2020 Kia Telluride LX, all- wheel drive. On the test drive, I could not go above 50mph, due to the traffic in the area. The following day, the had it on an interstate. I noticed between around 63 and 74mph, a hum and vibration. I called the dealer immediately and advised them of the issue. Prior to taking the truck in for the issue, I researched the matter. I learned this is a common problem with the all-wheel drive Telluride, no matter the trim level. The Hyundai pallisade AWD is experiencing the same issue. Both trucks share the same drivetrain. It is believed the vibration us being caused by the rear driveshaft being out of balance from the factory. After dropping my truck at the dealer, they later informed me, upon removing the rear driveshaft, the vibration ceased. The technician still heard noise coming from the transfer case. Upon checking the fluid, they found traces of metal in it. I was told it would take a month to get a new transfer case. Being unacceptable to me, they agreed to just get me a similar Telluride. The dealer had two other Telluride LX AWD and said they'd test them before I came back to try another. I was contacted and told one Telluride was fine and the other had the same problem as mine. Upon driving the one they said was good, I found the vibration was twice as bad as mine. I told the dealer this. They were to get another Telluride from another dealer. When it arrived, I was told it was fine. When I drove this particular Telluride, I first heard the noise I heard in my truck and the second, but no vibration. As I continued to drive, the vibration appeared at the same speeds as the other two. It became worse and then occurred at both a lower and higher speed range. The salesman experienced it as well. Owner didn't believe us, nor the service manager. Please see https://tellurideforum.org/threads/vibration.1108/

Experiencing vibration/pulsations while driving. Most noticeable starting around 65 mph up to 73 mph but seen to diminish or go away about 75 mph. Vibration can be felt on the gas pedal, seat and floor board. Also, there is an audible hum similar to a out of balance wheel or wheels. Possibly drive shaft, transfer case related, with the AWD.
