What 2021 Kia Rio owners say
Steering
Having been complaining about a noise from under the front right tire, I was initially told it was a little piece of plastic and that got cut off. I was still hear the scraping and squealing and I kept check the from right tire because I thought that's where it was coming from. I mentioned this to every mechanic at kia and was told "that's just how 2021s sound". Finally after months of complaining the noise got louder and you could hear it was clearly something in steering. They schedules an appointment for Dec 7th on Mon Nov 28th. Said it was safe to drive when that night while working I was turning a corner, I heard a loud spring noise, the tire and wheel jerked. It was snowing, so the car slide, only sliding into the curb. The front right break seemed to be locked and when you turn the steering wheel makes even more noise. …
On 3/19/23, as I was driving on a dry, straight, two lane road at the posted speed of 40mph, the car began to try to steer into oncoming traffic. I had to exert moderate force to keep the car in my lane. This continued continuously for about 1/2 mile. No low tire pressure indicator lights were illuminated, however the lane assist icon was on and green, indicating normal operation. Just as I was going to turn down a side street to check the tires manually, the steering returned to normal. However, the lane assist icon was now white, and as I drove the remaining approximately 2 miles home, the icon would change from white to green every 20 seconds or so. The car now operates normally. We took the car to the dealer today to be checked and they reported they could not replicate the issue. Attached is their report.

On the way to work, I had the brake pedal pressed waiting for a traffic signal to change. After it changed to green, I released the brake pedal and depressed the gas pedal, only for the vehicle not to move forward - as if the brake was still being applied. I took my foot off the gas pedal, waited a second or two, then tried the gas pedal again and it still did not move. I was at the traffic signal for nearly 10 seconds with nothing touching the brake pedal and unable to drive forward. The vehicle did not turn off, display any warning lights, or any signs of other trouble. The parking brake was not applied and the vehicle was in Drive. After putting the vehicle in reverse and back into drive while still stopped at the traffic signal, the car resumed normal operation. …
