NHTSA Complaint #11646065 — 2024 KIA SELTOS

The cruise control only works properly on level roads. When going downhill the car can go as much as 8 mph faster than the cruise control is set at. Going uphill the speed varies back and forth with the tachometer fluctuating up and down. I use cruise control to control my speed as well as reduce gas consumption. This cruise control system does neither. I believe this is unsafe. I did take the vehicle back to the dealer and showed him exactly what it is doing. He took a test ride in another Seltos and it did the same thing. The manufacturer said this is the way it is supposed to work. I have owned many vehicles in my 76 years and no other vehicle with cruise control worked like this. I believe this makes the vehicle unsafe when using cruise control.
