At speeds over 20 miles per hours there is a “flapping” noise that sounds like a bag or piece of paper that is blowing in the wind. Although I don’t know were the noise originates, I can hear it clearly from the driver’s side b-pillar. It is incredibly annoying and greatly diminishes what is otherwise a solid entry, level vehicle.

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.

The contol post for lights, turn signal, and high beams is too sensitive. To control the lights, you twist the top of lever. To turn on turn signals, you flip the lever up or down. To turn on brights, the lever goes forward. To turn of lights, the lever is pulled back. The issue..... If you have brights on, when you pull lever back to dim lights, the top automatically twists to shut off the headlights entirely. DANGEROUS DANGEROUS DANGEROUS. My husband doesn't have this problem, but he has longer fingers and his fingers hit the lever more at the base where nothing twists. I have shorter women's fingers and they can't reach all the way down the lever. I have since adjusted how I dim the brights by reacing under the lever, (close to steering column), to pull the lever back. This is very uncomfortable and tends to cause me to make the turn signal come on, which could cause its own traffic accident. My remedy would be to make the headlights twist in the opposite direction for

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. Haven't been told the issue, but I'm certain it is not safe and definitely shouldn't be on the streets until it's fixed.

I had driven my wife to her school about 5 miles and headed back to my work another 5 miles when i tried to accelerate pass car I lost almost all power barely making it up a slight hill I kept going trying to make it to my house barely going 10 miles an hour. I thought the transmission had let go cause while I had the gas peddle floored i went at best 10-15 miles an hour I eventually parked the car I knew it would never make it up another slight hill. It was rowed to a nearby dealer where they could find no problem telling me it was just some bad gas. This sounds like what I read about today with a couple of other models of Kia.
