2020 KIA SOUL Fuel/propulsion System Problems

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.

My car has been acting up almost every winter. Bought brand new and within two years would not start. Triple A had to get it started. Next winter it shook and the check engine light came on. There was a misfire. I called Kia of Queensbury and they just told me to keep the gas cap off for a bit and than drive it after putting it back on. I believe the fuel injectors were a problem at that point because at times when starting it would shake and it would lag in power. The check engine light did go off but it kept lagging and I had to put fuel in it more often. They did not diagnose it. The next winter it shook and felt like it was going to shut down. I took it in for diagnosis while it was under warranty. They denied anything was wrong. This winter it did it again. It shook and the check engine light came on. Even though I told Kia service in Queensbury NY that a computer said there was a misfire in cylinder 4 they insisted that if the check engine light was not flashing I could drive it. They wanted me to wait almost two weeks to get it diagnosed. Had I driven it as they stated I could have ruined the engine, it could have caused a fire or for me to have an accident. I called back told them it was shaking and dangerous to drive. They allowed me to take it in earlier. I had it towed in. Now that it is out of warranty and 64000 miles they admitted the fuel injectors had to be replaced and the spark plugs. Because of the issues I had experienced from the beginning, I believe the fuel injectors had been faulty for a long time and could have been a serious risk for myself and other drivers. It was dangerous. The fuel injectors and spark plugs have since been replaced out of pocket. I asked for the fuel injectors and spark plugs that were taken out of my vehicle to be given to me, but the service department did not comply with my request.

The car is frying my battery. I had a Duralast Platinum that should last approx 4 years. It killed one at 26 months. I replaced it, free of charge per the warranty, and 6 months later the brand new one is testing low again. Also, at 127k miles a flashing check engine light came on, I took it for a pre-check at a local shop and the tech identified that there was 0 oil in the reservoir. I had him change the oil just so I could get it out of there and took it into the dealership a day later. After charging me $250 for a diagnostic the dealerships response was that the cylinder walls and piston rings were damaged causing excessive oil consumption and that I need to replace my engine. $9,000 for a new engine at 127,000 miles is ridiculous. Apparently just about every other model but mine was recalled. I had to take it in for a recall last year.

Car is suddenly stalling without warning during idling or slow acceleration. No check engine light initially appears. When the stall happens a check engine light comes on. When the car restarts there is not a check engine light. Car will sometimes mar a funny sound like a loud fan and jerking motion before acting “normal” but when idling at a light again will suddenly turn off. Car will start back up again, no warning lights, no check engine, etc. when doing a read of the computer there are no codes to determine any issues.

Second engine installed in the car ceases to fire. Condition does not change with new sensors for camshaft nor crankshaft. Engine turns freely cranks but will not restart. Unreliable driving conditions. Mathew’s Kia wants $1400 upfront to start exam in blind faith to see if a properly serviced car has a common warranty claim

When taken for oil changes, no oil is left on stick and motor will lock and cut off. I have to restart the car to get it to turn on.

The entire car is infested with Mold due to a prior evaporator leak that was improperly installed prior to my purchase of the vehicle. The dealership Lighthouse Point Kia in Pompano, Florida, refusing to fix the car issues.

Appropriately April 2024, The engine service light came on at about 115,000 miles, followed by the 2020 Kia Soul X-line engine stopped running. I tried turning off the key and attempting to restart the car however it would start but for only a few seconds. After 5 or 6 tries to restart the car, I finally turned off the car, waited about 3 minutes and then restarted the car in as it continued to run. The check engine light remained on but I noticed that there was a drop in power when I tried to accelerate. Since then I have notice the engine check light go on and off several times. I recently brought my car in to have an oil change only to find out that there was no oil on the dipstick. I signed a form stating this and got the oil change completed. I have had the Software Program installed about 3 months after I heard of the recall, however the Local Kia Dealer will not do the diagnostic unless I pay a diagnostic fee because I have a check engine light on... I am calling KIA at the corporate number tomorrow to ascertain " IF " I will still have to pay for the Recall issues ...

I bought my car brand new off the lot 0 miles on it. Recieved a letter in mail Dec. 7th 2021 bout the pistons not being treated properly. And the software being available. I've been putting anywhere from 1 quart to 1.5 quart of oil in weekly. There's no leaks no smoke not sure where oil is going. It stalls when stopped or idling. When in park will stall. After I get gas it won't start I have to put gas pedal all the way to floor and hope it's turns over and when it finally does I have to keep it idle over 2rpms or it sputters til it stalls. I feel these are continued safety issues. Besides my oil issue gas mileage is awful.

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.

I was driving down the road when all of a sudden the engine started to sputter and shake violently. I couldn't get it to accelerate. I pulled the vehicle to safety and shut it off. I looked under the hood and saw or smelled nothing unusual. I restarted the vehicle and it ran okay. I went immediately to a Kia dealership. I was told that if it was running okay to make an appointment for the next day. I did. The battery was changed out and I was told it was fine. It is not. The same thing happened again, several times. I am being told that if they can't duplicate the problem, they can't fix it. This problem is very unsafe given the entire vehicle slows to an almost stop, even on the highway, at times. I have researched this and it is a common problem with this engine. Many have caught on fire. Kia sent out to the dealerships a Technical Service Bulletin, Number 203, on March, 2019, for Model 2020My Soul(SK3) 1.5T, addressing this problem, yet the local Kia dealer does nothing about it. I was told the recall on this vehicle for the Improperly heat-treated piston oil rings was taken care of but I have to wonder.

For many months car has been randomly stalling. It has never been able to be duplicated at dealership, therefore it hasn't been addressed. In recent weeks the stalling is more often and is now accompanied by a check engine light.

BOUGHT BRAND NEW. AT 32K MILES (4MONTHS AFTER 30KTUNE UP) ENGINE LIGHT CAME ON. TOOK TO EARNHARDT KIA IN PHX. WHO INITIALLY STATED THERE WAS 'SOMETHING BROKEN IN THE TRANSMISSION' AFTER A FEW HOURS THEY THEN STATED THE CAR HAD 'INTERNALLY OVERHEATED AND THERE WAS COMBUSTIBLE GASES IN THE RADIATOR. THE THERMOSTAT NEVER INDICATED OVERHEATING. COOLANT RESERVOIR WAS BONE DRY (AFTER FILLING IT THE DAY BEFORE). AFTER 31 DAYS AT KIA A NEW HEAD GASKET WAS PUT ON.. THOUGH I WAS TOLD THE CAR WAS GETTING A NEW ENGINE. I ASKED THE DEALER ON EACH CALL... WHAT ABOUT THE TRANSMISSION WHEREAS I WAS TOLD KOA WOULD MAKE SURE EVERYTHING WOULD BE FIXED BEFORE RETURNED. CAR WAS RETURNED TO ME ON 2/21. ON 4/1 AFTER DRIVING 380(+/-) MILES FROM PHX TO SAN DIEGO TO SEE MY MARINE DEPLOY, THE CAR BEGAN TO SURGE, RPMS SKYROCKETED AND CAR BARELY MADE IT UP HILL. SURGING CONTINUED, UNTIL IT BEGAN TO SLIP AND I PULLED OFF THE ROAD AND INTO A SHOPPING CENTER. CAR TOWED TO ESCONDIDO KIA WHO KINDLY GAVE ME A LOANER. NOW BACK IN AZ, I AM TOLD THAT WHEN IT'S FIXED, TRANSPORT TO ME IS UNLIKELY AND IF APPROVED KIA DOES NOT GUARANTEE AGAINST ANY DAMAGE DURING TRANSPORT. ITS A NEW CAR! DUE TO MEDICAL NEEDS HERE, DRIVING 6.5 HOURS THERE AND THEN BACK JUST ISN'T FEASIBLE. KIA DOESNT CARE. I WILL BE OUT OF THIS CAR ASAP AND YOU CAN BET MY NEXT WILL NOT BE A KILLER KIA!

I BOUGHT THE CAR IN MAY 2020. I FIRST REPORTED THE PROBLEM IN JULY. IT HAS SOMETHING TO DO WITH THE IDLE STOP AND GO FEATURE, AS IT ONLY HAPPENS WHEN THIS IT IS BEING USED. WHEN I COME TO STOPS AT RED LIGHTS AND STOP SIGNS. EVERYTHING SHUTS DOWN. WHEN I RELEASE MY FEET OFF THE BREAKS THE CAR MAKES A DULL QUAKE LIKE NOISE. I HAVE HAD THE CAR IN THE SHOP AT THE DEALERSHIP FOR 7 DAYS ALREADY. THEY CHANGED THE BREAK BOOSTER THINKING IT WAS THE PROBLEM, BUT IT WAS NOT. I HAVE BEEN TRYING TO SCHEDULE SOMEONE AT THE DEALERSHIP TO RIDE WITH ME FOR A FEW MINUTES TO LISTEN TO THE NOISE. ABOUT A WEEK AND HALF AGO I GOT AN REPLY TO AN EMAIL TELLING ME TO HOLD OFF ON THAT, BECAUSE ANOTHER CAR HAS COME INTO THE DEALERSHIP WITH THE SAME PROBLEM. I WAS TOLD THEY WILL CONTACT ME WHEN THEY FIGURE OUT WHAT IT IS. THIS PROBLEM HAD BEEN GOING ON WORKING ON 5 MONTHS NOW.
