2020 Kia Soul Powertrain (other) Problems

The contact owns a 2020 Kia Soul. The contact stated that while driving at an undisclosed speed, the vehicle stalled without warning while releasing the accelerator pedal. The vehicle restarted after each failure. The first dealer diagnosed the vehicle and retrieved DTC: P04100 (Camshaft Position Sensor A Circuit); however, the repair failed to fix the vehicle. The vehicle was taken to Hendrick Kia of Concord (7550 Hendrick Auto Plaza NW, Concord, NC 28027); and the technicians informed the contact that the vehicle was not properly repaired. The vehicle was returned to the first dealer, and the dealer failed to duplicate the failure. The dealer dismissed the contact’s concern that the vehicle was consuming an excessive amount of engine oil. The contact was informed that adding one quart of oil per 1,000 miles was within normal operation of the vehicle. Upon investigation, the contact related the failure to Kia recall SC199. The manufacturer was notified of the failure and provided a case number and referred the contact to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 34,000.

While driving on the interstate at approximately 70 MPH, the vehicle suffered a sudden and complete loss of forward motive power. The engine revved, but the vehicle completely ceased forward acceleration and could not maintain highway speeds. This created an immediate safety hazard, forcing me to navigate across active lanes of highway traffic without power to reach the shoulder, narrowly avoiding a rear-end collision. Once stopped, the vehicle completely refused to engage any forward gears (Drive). However, the transmission will still engage and move backward in Reverse. This is the second time this vehicle has experienced a total transmission failure in 6 years, despite having previously had the transmission replaced at an authorized dealership under Kia Service Campaign SC199. The replacement Intelligent Variable Transmission (IVT) component has suffered an identical, catastrophic mechanical failure to the first unit. The manufacturer’s previous campaign remedy failed to permanently resolve this severe highway safety defect.

The problems with the KIa Sol began with the "check engine" light continuously coming on in January of 2025. Took it to the dealership twice and numerous repairs were made and the vehicle continues to malfunction. It sputters and has created a dangerous condition to drive. For example, my 21 year old son was on the freeway and the car started sputtering. Thank God that the truck behind him moved lanes when he saw the car was struggling or it could have ended tragically. That was incredibly scary. I took it to the dealership again. They kept for two weeks trying to find the root of the problem, I spent $4,000 to "fix" it. When I drove it around town it did the same again, which put my brother and I in danger. The dealership finally said that the car needs a catalytic converter, which I was quoted as costing approximately $5000 dollars. I have spent a lot of money to try to fix this car and have been in two dangerous situations because the problem was not located. I have been trying in good faith to work with the dealership and KIA corporate to put a new catalytic converter by requesting a good will gesture.

The engine began to sound like it was missing or sputtering. This occurred for a short period of time, and then the sound stopped. The next day the sound started again, shortly after engine seized while driving which created a very dangerous situation. After about 10 minutes the vehicle restarted, was making a sputtering noise, and was driven a short distance into a parking lot. Still, no warning lights appeared on the dashboard, vehicle was towed to a KIA dealership. At the dealership, 4 days later, We were told that the vehicle was completely out of oil. The check engine light, nor the oil icon, came on at any time. There was no evidence of an oil leak of any kind. There has been no damage to the vehicle. The vehicle has received regular oil changes either at a dealership or at a business that supplies oil change services. The engine seizing, really with no warning, created a dangerous situation.

My car randomly started stalling and turned off while I was in the middle of a busy intersection with both my children in the car. I had to turn on my hazards and turn off my car and turn it back on and press on the gas pedal. The car did that four times in less than 30 minutes. I am not the original owner of the vehicle, but the previous owner did have the cars camshaft repaired when I took it to the mechanic on 4/21 that was when I found out about the previous owner having the same issue as I am. I called Kia of America regarding the recall on 2020 Kia souls. They ignored my request and told me there was nothing they can do as my warranty was expired. I then proceeded to call carmax where I bought the car and was never informed that there was mechanical issues and that the car was safe. I did the research and saw there is a recall on 2020 Kia soul for improperly heat treated piston oil rings and that a damaged engine may stall, increasing the risk of a crash and that oil may leak into hot exhaust causing a fire.

The vehicle started with what felt like the car was going gently slower and faster as if it was almost out of fuel but had a full tank. This happened a couple times and I had the dealership check it out but they were unable to recreated the problem. This progress to a more obvious gear shifting harder or not when it should. There are times where when I try to accelerate, it shutters and doesn't want to go. I just recently had an issue after stopping for gas, where it lost power all together and started to almost redline. I pulled off to the side of the road and made several attempts to get going again and it would rev up but was not giving any power to the wheels. I shut off the vehicle and let it sit for a for moments and turned it back on and tried again and was able to get moving again. It didn't act up again until a few days later when I was heading to work. It would have this gentle feeling of having power and loosing power on the highway. When I got off the highway and started to go after I stopped it shuttered hard and I took my foot off the gas and it stopped and I was able to go. This is all the same characteristics of the vehicles with this transmission that do have a recall. This recall needs to be extended!!

Unresolved Recall. The vehicle was under recall in 2019 and should not have been sold by JTs Kia in Columbia, SC. The piston oil rings were affected in the 2019 recall and also caused an issue for the 2020 Kia Souls. The car was sold under recall. Once the revised recall came out in 2021 JTs Kia did not properly resolved the issue and later the car engine overheated and caught fire. JTs Kia Never took responsibility and told the South Carolina Department of Consumer Affairs that the Kia Corporation will not honor any repairs. The car was no longer able to turn on and JTs KIA is still selling these dangerous cars that has had piston oil ring issues since 2010

Approximately 30 miles into a trip, with mostly highway driving, the transmission failed completely. Stepping on the gas pedal caused the engine to roar but did not move the car. Unfortunately, this happened while I was driving eastbound on the San Francisco Bay Bridge, causing a very dangerous situation. There was a slight downhill at that point, so I was able to coast, but eventually the car stopped. Once it stopped, I turned off the engine and restarted it and put the car in Drive, but this did not enable me to move the car. I tried this a few times. This put me in great danger of being hit by other cars. Fortunately, the passenger was able to call 911 and a CalTrans tow truck arrived soon and pushed my vehicle, first to the shoulder and then into a bridge parking facility between the eastbound and westbound lanes. Another fortunate thing was that the traffic was moving well below the speed limit.

The car stalled when coming to a stop and would not start for over 5 mins while on a major road. When the car finally started engine light started to flash and at a fast speed. Got the car home and noticed the oil leaking heavily. I have only had the car for 2 weeks so I took the car into the AutoCare shop for diagnoses and the code came back as code p1327. I was told the car must go to the Kia dealership immediately and be towed.

I recently purchased this 2020 Kia Soul at the end of April 2023. About 2 weeks ago while I was stopped for a red light in a busy intersection and the "restart" feature was engaged as I had the brake pedal pressed but then as the light turns green and I move my foot from brake to gas (that step is supposed to restart the engine) it did not start immediatley as it should have, Which left me in the lane of traffic vulnerable to possible accidents until it restarted. It finally started after what seemed to be forever and embarassment caused by the restart failure. This event could have had a different outcome if the car wouldn't have restarted. I am taking the car to the dealer tomorrow to have it inspected. I wasn't that there was even a problem until this happened there were no warning lights. I also recieved a "voucher" in the mail to take with me to the dealer stating that my car is a high risk potential pre existing conditions with mechanical or electrical issues. I have only had this car less than 2 months and am already having issues with it. I think I'm regretting this purchase. There is also a sluggish gear shift in the transmission it does'nt seem to be working properly also an engine knock that wasn't there previously. It's not even due for the first oil change since purchase. Kia shoulkd get it together and stop duping unsuspecting naive first time car buyers like myself.

My experience: My transmission failed while driving at full speed on the highway. My car initially started balking, with RPMs jumping between 2000 and 3000 RMPs. Then, it revved high and RPMs suddenly jumped into the red while the car was not propelling forward at any real speed. It was an extremely dangerous, scary situation in the rain, with an 18-wheeler right behind me. I am grateful to have made it to the dealer without having a crash. There were never any warning lamps and this happened out of the blue, without prior warning. Dealer report: "Metal debris on speed sensor; transmission internal failure. Techline authorized transmission replacement." Transmission has been replaced.

While driving along the interstate, going 70 MPH, I noticed the RPM gauge started to fluctuate. Shortly after, I started having issues maintaining the speed. I pressed the gas pedal, but the vehicle wouldn’t speed up - instead started loosing speed. I started to hear grinding noises as I pressed the gas pedal. Eventually, I kept loosing speed and there was nothing I could do to make the vehicle move. I had to pull off and coast into a parking lot to be towed.
