There are 6 owner-reported speed control & cruise complaints for the 2020 Kia Soulin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2020 Kia Soul. The contact stated while driving approximately 35-40 MPH, the vehicle stalled with several unknown warning lights illuminated. After several attempts, the vehicle was restarted, and the contact was able to pull over to the side of the road. After waiting for a while the contact was able to restart the vehicle and continued driving slowly; however, the failure recurred. The contact had to turn off and restart the vehicle several times. The vehicle was taken to an independent mechanic where it was diagnosed that the throttle had failed and needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 30,000.
When I would come to a complete stop at a stop sign it would stall battery light and oil light would come on. I would need to put it in park then turn it off and turn it back on. It also would suck up oil like crazy I would need to replace the oil every few days otherwise it wouldn't start. I took it to the shop and 2 of the 4 pistons blew and all the timing stuff stopped working.
I was driving to work. 12 miles my oil leaked. A state trooper turned around when seeing flames and called the fire department and tow truck. I lost control of the car, nothing was working. I was only ever given one recall notice which I fixed 2 months after buying the car. The car also has issues with security. Only certain insurance companies will cover the car and their prices are higher. We took car to dealership . three months later I contact attorney general. The GM this started attacking us, denying anything happened etc. He should be fired for how he treats people. Reviews of their business show others have had issues. Kia corporate has always told us they r waiting on images yet this GM contacted them, told us to leave, and screamed he would charge us for every day it was on lot. So we had it towed the next day. Insured company will be doing their own I xpection. This isn't about money, its about safety and these cars have slot of issues. It is wrong to blame the consumer for a faulty product. We had to get new car and now upside down in this one. We bought thus Kia be,cause the previous one the engine seized. We expressed our concerns, but got put in another car with issues. Kia corporate has been non talking to us the entire three months, so the only findings can be based on what GM said. They washed the motor. It sat so long the battery died. Someone went through papers in the glove box then left them out. We had medicine in the loaner, which they say is a lie. My daughter drives the car and recently was laid off. So now she can't have her medication..... Although she left it in the car they had no right to do that. There was plenty of other issues along the way.

While driving on the highway at 60 mph, the vehicle Started To feel like it was trying to go forward (thrusting) on its own. It then accelerated on its own to over 80 mph. I slammed on the brakes and pulled over and put it in park.the engine was revving in park. After Kia roads on assistance couldn't send a tow truck,I thought I would be okay driving on the emergency lane The 2 miles home from the highway. As I put the car in drive, the engine was revving at 6 On the gauge but the vehicle Wouldn't go over 20 miles an hour. It is at the dealership today. There were no warnings or lights or sounds.It all started with the slight thrusting of the entire car. I could have easily slammed into the back of another vehicle if it had been in front of me.
WHILE PULLING INTO DRIVEWAY AND COMING TO A STOP AND THE ENGINE TURNED OFF . I LET MY FOOT OFF THE BRAKE AND THE CAR TOOK OFF LIKE A ROCKET AND HIT A PARKED CAR IN OUR DRIVEWAY . IT PUSHED THE PARKED VEHICLE FORWARD ABOUT 2 FEET UNTIL THE CAR STOPPED . THIS IS A DIRT DRIVEWAY. I GUESS WHAT HAPPENED IS THIS CARS START AND STOP FEATURE WHICH TURNS THE MOTOR OFF WHEN YOU COME TO A STOP AND STARTS BACK UP WHEN YOU LET YOUR FOOT OFF THE BRAKE . SOME KIA FEATURE THAT WENT HAYWIRE AND CAUSED THE ACCIDENT . YOU CAN DISENGAGE THIS FEATURE BUT IT MUST BE DONE EVERY TIME YOU STOP AND TURN OFF HE VEHICLE . THE DEALER DID NOT EVEN WANT TO LOOK AT THE VEHICLE AND SUGGESTED TAKING IT TO A MECHANIC TO MAKE SURE THE RADIATOR WAS NOT DAMAGED .
