I was driving up a hill and it would not go past 20-30 mph, and the rpm will sometimes go up when not accelerating. The transmission does not shift when driving and will sometimes make the car stop and go stop and go continuously. Tried accelerating but the rpm would go up while the mph would not.

I believe my Kia Rio S falls victim to the recall 2020 Kia Rio models have faced. Brake performance has been severely degraded on my vehicle over the past few weeks despite doing all recommended maintenance. When I first got my 2020 Kia Rio S I could brake with 5% pressure applied to the brakes, now it takes about 25-30% pressure and it seemingly is increasing every day. I have contacted the manufacturer and they advised me it would be a $2000 service charge minimum.
