Discovered the "cancel" button on the cruise control cluster was not working. Hitting the brake pedal or shutting off cruise still disengages the cruise control. I am reporting this complaint before dealer inspection of the problem. It is not user error and I have tested it several times having the same failure.

I use cruise control frequently so am very familiar with its operation and was happy that I discovered the "cancel" button was not working on a stretch of road where I simply chose to shut it off and wasn't approaching a vehicle or traffic signal at speed!

I purchased my 2016 Kia Sorento 2.4L FWD on 05/16/2015. Today is 12/26/2016. This was my first Kia Sorento. My 2016 Kia with 200 miles has a cruise control problem. When my Kia service garage contacted Kia about my problem, Kia's answer was as follows - under no circumstances are you to use cruise control upon approaching or descending an incline or decline greater than 6 degrees. I live outside of Pittsburgh, PA and need I tell you that this statement means I can hardly use my cruise control at all. This is unacceptable!

Here is the issue: with cruise control for example set at 62 MPH engine RPM is like 1975 RPM and coasting down a hill -- all of a sudden you notice the car picking up speed because it's going down a decline or a hill -- the engine RPM becomes erratic with the needle hitting 1000 RPM and then to 3000 RPM and then back down to 2500 RPM and as your coasting down the hill you can feel the auto controls slowing the car down trying to keep the speed at 62 miles per hour but as you look at the RPM again you are now descending at a steady 5000 RPM and you still notice the system trying to do the braking as your traveling down the hill.

Something wrong here -- I don't want to blow the engine. On a flat surface or going up a hill the cruise control seems to be performing okay. My Sorento had 8200 miles on it when I finally unloaded it. But after months of waiting for a Kia representative to talk with me at the dealer, and after he and I took my Sorento and a new 2017 Sorento (which did the SAME thing) out for a test drive, I was being told that "this is the way this Kia functions and nothing is going to be changed on it at this time". I use my cruise control often, and this was NOT ACCEPTABLE! So, I took a BIG loss and unloaded it. I just don't want anyone else to purchase this vehicle and have to go through what many of us have gone though - and then find out that Kia WILL NOT correct the problem.
