While driving normally on the highway, i've continuously experienced the car randomly revving between 3000 and 4000 rpms while driving on the highway and on regular roads. it will get stuck at 2000 rpms and will not accelerate or decelerate no matter how hard the gas/brake is pressed. it has been taken to the dealership i purchased it from twice now, and both times they have told me they cannot find anything wrong with the car, no codes or anything. i do not feel safe in a car i'm paying $402 a month for. i have contacted kia corporate in atlanta and opened a case with kia consumer assistance online. waiting response from both. will not buy another kia after i lemon law this car. my family has always had kia's and never had any issue with them. i previously had a 2016 sportage that also had transmission problems.
In the range of 1200-1500 rpm and speeds in the 40 mph range there is a vibration and hesitation especially on any degree of incline. more seriously, the problem repeats at 2000 rmp at highway speeds from 65 mph upwards. there is a vibration and serious lack of response to increased pressure on the accelerator. it is worse on any incline but happens on level road as well. the car will not respond to trying to increase speed unless i really push hard on the accelerator and then it is still slow to respond. the problems seem to be getting worse possibly due to the summer heat. i do not feel safe on the highway. this has been reported and examined at the local dealership and a report filed with kia but i have not been able to reach them in person.
