2015 Kia Soul UNKNOWN OR OTHER,ENGINE

I am getting a code that indicates an issue with the catalytic converter. P0420 to be specific. The engine is continually misfiring and check engine light comes on and off randomly. Car broke down completely at one point in October and had to replace the battery but check engine light was still on when I got it to start. The car shakes uncontrollably every time I drive it and gets even worse when idling. I took it to a mechanic and they believe it to be amongst the 2011-2016 SC176 recalled Kia Souls where high exhaust temperatures can damage the engine’s catalytic converter. Have attempted to take it for repairs/open recall and the manufacturers have consistently refused. Help in getting this issue sorted out would be much appreciated.

There was a knocking sound, so I pulled over and smoke started coming from underneath the hood of the vehicle. There was a fire and the car was later deemed a total loss.

The engine system in my 2025 Kia Soul malfunctioned, as indicated by the activation of the P1326 warning light. This diagnostic code typically signals serious engine issues, such as potential rod-bearing damage. Despite this warning, the authorized dealership, Jim Bone Kia of Santa Rosa, only replaced the knock sensor after I asked to conduct a Bearing Clearance Test (BCT), which they claimed passed. However, prior inspections had revealed metal debris in the oil, which strongly suggests internal engine damage. The failure to conduct a thorough investigation into the potential engine damage poses a significant safety risk, as the vehicle could experience a catastrophic engine failure while in operation. Such an event could endanger my safety and the safety of others on the road. The dealership has not reproduced or confirmed additional issues related to the P1326 code, claiming they require further symptoms (e.g., audible engine noise or a repeat warning) to proceed with deeper diagnostics. This approach delays necessary repairs and leaves unresolved safety concerns. Additionally, the vehicle’s catalytic converter was initially denied warranty coverage, despite being included under an extended recall. This created confusion and delayed essential repairs. The P1326 warning light appeared before service, and the knock sensor was replaced, but no further proactive measures were taken to address the root cause. The vehicle remains at risk of more severe engine damage and safety hazards.

The Kia experienced acceleration issues and would randomly turn off while driving. A mechanic inspected and recalibrate the knock sensor. Almost immediately the car began to use excessive amounts of oil, a quart a week average, had a knock and started having acceleration issues. The Kia dealership stated that severe engine scoring had occurred likely caused by the catalytic converter. The problems began and lead to engine failure within several weeks. From March to end of May

The catalytic converter got pluged up from the oil consumption. The car would no longer accelerate. Yes I still have the catalytic converter.yes the safety was I went to excelrate and I almost got rear ended. It just happened out of nowhere.I took it to the Meineke's shop and they said the cat was pluged but wasn't 100% sure so I had it towed to a kia dealer and they said it was 100% the catalytic converter and it wasn't covered so it would be around $3000.Yes it was inspected by the kia dealer.It had a check engine light on but it said it was the 02 sensor. It had a little less power then normal.It seemed ok when I left the house. I drove about 40 miles. I stoped for about 5 minutes to smoke and it seemed ok in the parking lot. It's when I went to excelrate out to the street it had no power.the original cat starts getting pluged over time and causes the heat to back up on the inside of the engine and puts wear on the piston rings. There for causeing it to burn the engine oil. Inturn almost fully pluging the original cat cause the engine to have no power. I have been a professional machnic for over 24 years. so I understand how engines work. Now because of the internal damage of the engine I am putting 2 quarts of oil every 1500 miles. Which is only one week for me. Thank you for reviewing this. I hope that kia will make this right.

Starting in summer of 2021, I began to has acceleration problems with my car and a check engine light came on. It was undrivable so I took it to the closest mechanic I could make it to, Firestone. They found the catalytic converter to be the problem and I paid $1100 to replace it. Later in 2021, the catalytic converter went out again and I had to have the engine coil and spark plugs replaced. I took it back to Firestone to replace it under warranty. During 2022, the check engine light came on again and again it was the catalytic converter. I got it replaced under warranty again. During this replacement, Firestone let me know that my engine was the source of why the catalytic converter keeps going out. The compression was too low and the engine was causing the catalytic converter to overheat. I took it to the dealership to have it diagnosed to see what was wrong in the engine. They claimed to have run diagnostics in the entire engine and only found that the engine coil and spark plugs needed replacement. I had both of those things replaced already the year before. They did not identify any problems with the new catalytic converter or any other part of the engine. The check engine light came on and my catalytic converter has gone out again and caused me to lose acceleration on a one lane each way 60mph road on my way to work. I suddenly slowed way down and cars had to swerve around me. I pulled off onto a farm road to let traffic by and then had to hobble to AutoZone nearby with my hazards on to get my check engine light codes read. It came up that the cat converter was having issues. I looked up to see if my car had any recalls and none were found. I did find that there was a major recall for Kia souls 2012-2018s for some piece of the engine that was causing catalytic converters to overheat. Many individuals who had this recall done to their vehicles also had to have engine coils and spark plugs replaced based on a forum regarding this recall.

My car lost power going up hill on Interstate 5 and ended up seizing up. I could not bring the car to highway speeds I had to drive home using side roads. A mechanic said the car appears to be consuming oil and degraded the catalytic converter. I had to have my catalytic converter replaced. I had the recall done on my car for the catalytic converter issue identified for 2015 Kia Souls. I attempted to get repair from my dealer, Gweke Kia, under this recall but they refused and said I would be charged for the repair and diagnosis. I asked for an oil consumption study to see if the car qualifies engine repairs or replacement under my warranty but they informed me they would charge me approximately $1200 for an oil consumption study.

My catalytic converter went out on my Kia while driving unexpectedly and I have heard of a lot of other Kias in my year have the same issue.

Engine burning oil so much that it destroys the catalytic converter leaving me stranded middle of a highway.

Shucks was taken to Kia Country of Savannah for recall repairs. ECU update and seat belt cover repaired, however, I explained that car was burning oil (but not leaking) and engine was on and car was making a knocking sound. I had taken my car to a local mechanic while informed me that my car’s engine was bad. I even showed Pat Foran the printout that I was given. The local mechanic I found that I would qualify for the engine replacement based off of his inspection. So I took the car to Kia (barely made it because the car would not go over 60 mph. At Kia, I was told my car passed bearings test and that I would need to pay for a fuel consumption test to determine what was wrong with my car. I was told I would know if my car needed a new engine because it would sound like rocks in a milk carton, which it did but the folks at Kia said they drove it and didn’t hear anything. I find it very strange that my engine light was also off when I got the car back but 20 miles down the road, as I putted my way back home, it came back on. I feel this was there attempt to not fix the car, they were too busy trying to get me to trade it in because I only had 93000 miles on it at the time.

While driving home from work late at night, the car just stopped without warning and would not start again. It was towed to the dealership where I was informed that there would be a $750 diagnostic fee, but that Kia would probably not replace the engine under warranty because the recall had not been taken care of. I am the second owner of the vehicle and bought it the same year that the recall was issued. Kia consumer affairs department states that it was sent to my address, but I did not receive the notification. I cannot afford to pay $750 to find out that I will not be reimbursed and I cannot afford to have the engine replaced in a car that is worth the value of the engine. I had just changed the oil and had a valve cover gasket replaced. There was no check engine light.

At the inspection & emissions test on 01/10/2023, the vehicle failed with a P0420 cat code & Kia recommended I pay to replace the catalytic converter. The first P0420 was found in Aug '19 at an Auto Zone. The vehicle is available for inspection. My safety & those of others is at risk per the recall number 19V120 dated 04/12/19: "A defect has been identified which relates to motor vehicle safety. The defect may cause damage to the catalytic converter... If this condition occurs, you may hear knocking noise from the engine and/or the Malfunction Indicator Lamp (MIL) may illuminate. Kia will upgrade the Catalytic Overheating Protection (COP) logic in the Engine Control Unit (ECU) and if necessary replace the catalytic converter and/or engine at no cost to you." This Kia's ECU was upgraded on 04/24/19. About 3 months later, the check engine (CE) light illuminated. Auto Zone found a P0420 code but the Kia dealer found a P0455 & suggested the gas cap was not installed properly. They cleared the code and sent me away. The CE was back on Nov '19. An appointment with Kia on 01/14/20 revealed a P050A code which had no resolution. The dealer "reset engine adaptive values as per techline and released vehicle back" to me. I drove in stress, praying the vehicle doesn't catch fire since it was losing significant oil. I added additional quarts about 1500 miles after each oil change. After a while I got used to the CE being on. In August of '21, AutoZone found a P0420 diag code again. I didn't think Kia would resolve the problem. I finally called Kia in May of '22 & was told of another recall #SA485. I took the Kia in on 05/31/22 with the CE light on. After the ECM upgrade the CE light was off until a few miles were driven. Inspection on 01/10/23, Kia dealer found P0420 Cat Code, failed the vehicle, & told me vehicle is no longer covered under warranty. I think the vehicle should have been recalled for catalytic converter like other 2015 Souls. Please recall this Kia.

Having catalyst system efficiency below threshold issues The engine light is on code is P0420 Autozone gave me the diagnostic Engine light turns on and off

The contact owns a 2015 Kia Soul. The contact stated while driving approximately 20 MPH, the engine hesitated and emitted smoke from the tailpipe. The contact stated no warning light was illuminated. The vehicle was taken to a local dealer where it was not diagnosed. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 20V750000 (Engine) however, the VIN was not included. The manufacturer was informed of the failure and the contact was awaiting a response. The failure mileage was approximately 74,000.

In the past year my 2015 Kia Soul has been loosing power, burning oil not leaking and if you have to drive more then 2 hours you have to put oil in it. The engine shakes we took it for a recall but the issue was never fixed.

I recieved a notification of an engine recall for my Kia Soul. Took it to the nearest dealership an was told the issue was resolved. This was roughly March 1 2021. My check engine light appeared and was diagnosed as a catalytic converter/engine issue . Had vehicle towed to the dealership and after a week or who was told the issue was related to the recall and good to go Roughly 4-6 weeks later check engine light reappered with the same malfunction code. Vehicle has been towed to the dealer to diagnose and fix. The kia dealerships in my area are quoting serviced appointments months out, with no courtesy cars offered. Some dealerships have refused service altogether,.

Unknown Consumer stated car broke down on October 29th, car was driven less than a mile, when consumer heard a noise coming from the car. In trying to pull over, car screeched and came to a stop. There was a loud metal knocking. Consumer noticed that the sound was louder when I stepped on the accelerator or started the car. No lights illuminated on the dashboard. Consumer decided that it was not safe to drive and towed it instead. Vehicle was taken to a dealer for diagnosis. KIA Customer Care was contacted to assist with the issue. Consumer was notified that there were 3 recalls on the car. SC-200, SC-155, and PI-2002. At that point, dealer towed consumer's car to a dealership to complete the recalls since it was believed that the car malfunction was due to one of these issues, but no diagnostics were run by the dealership to confirm. On November 2nd, consumer's case was closed without notice. Consumer reached out to KIA customer care and was told that there was nothing they could do to complete the recalls and was not covered under any warranty.

During the month of March 2021, I received a recall letter from Kia Motors America involving a potential engine fire. The vehicle was taken to the local Kia dealership for service. The problem was the loss of oil. The dealership replaced the pan and I incurred the cost of an oil switch replacement. The next incident, June 2021, was the replacement of catalytic converters. Following this, my check engine illuminated and the car was taken to Kia. They replaced the knock sensor (July 2021). In August 2021, another knock sensor replacement. The vehicle continues to lose power and fail to properly accelerate. October 2021, vehicle taken to dealership and I am informed of the catalytic converter requires replacement. Since they are under warranty, the vehicle was taken to the independent dealership that informed me that this situation with the catalytic converters will be ongoing because the engine is bad. The pistons and valves require replacement. Kia refuses to replace the engine unless the connecting rod barring fails. My concern is the use of the word safety; especially knowing that this vehicle and probably many more will encounter major engine malfunctions.

WHEN DRIVING DOWN THE ROAD ON A CITY STREET GOING APPROXIMATELY 50 MPH, MY VEHICLE BEGAN TO MAKE KNOCKING NOISES AND THE SEIZED AFTER I PULLED OVER TO THE SIDE OF THE ROAD. WHEN I GOT OUT TO CHECK THE OIL IT HAD ALL LEAKED OUT ONTO THE ROAD CAUSING MY OIL TANK TO BE DRY. THE CAR NOW WILL NOT START AND KIA HAS REFUSED TO FIX IT AND SAYS I AM OUT OF WARRANTY, BECAUSE I AM NOT THE FIRST OWNER OF THE CAR EVEN THOUGH I WAS OFFERED THE WARRANTY WHEN I PURCHASED THE CAR.

WHEN I GO TO COME TO A STOP AT A STOP LIGHT OR STOP SIGH, SOMETIMES THE ENGINE WILL STALL OUT AND ALL POWER IS LOST. THE HAVE TO TURN THE CAR OFF COMPLETELY AND RESTART IT. THEN IT DRIVES FINE AGAIN UNTIL I COME TO ANOTHER STOP. IT DOESN'T HAPPEN ALL THE TIME BUT IT HAPPENS ALOT.

WHILE DRIVING HOME AND AT A STOP SIGN MY CAR BEGAN TO KNOCK SOMETHING FIERCE, BEING A FEW HOMES AWAY PULLING INTO DRIVEWAY. I NOW HEAR LOUDER KNOCKING AND A NEW CLANKING NOISE (METAL IN WASHER SOUND). CAR WAS TOWED TO MECHANIC I WAS TOLD THE ROD WAS BUSTED. NEEDS AN ENGINE OVERHAUL. IT HAS 78,000 MILES ON IT AND NO LONGER RUNS. ALL MAINTENANCE WAS KEPT UP ON THIS CAR, THIS WAS NOT DUE TO MY NEGLECT AND THE CHECK ENGINE LIGHT DID NOT COME ON. A CAR I CAN'T AFFORD TO FIX AND STILL PAY FOR.

MY ENGINE LIGHT COMES ON AND GO OFF. MY OIL IS ALWAYS LOW.

MY 2015 KIA SOUL IS MISFIRING AND THE ENGINE LIGHT IS FLASHING. I RECEIVED A RECALL AND TOOK THE VEHICLE TO STEVE NAPLETON KIA OF ELGIN. THEY SUPPOSEDLY PERFORMED AN ECU UPGRADE AND SENT ME ON MY WAY. MY CAR DIDN'T HARDLY MAKE IT OUT OF THE LOT BEFORE SHAKING LIKE CRAZY AND ULTIMATELY STALLING. I TOOK IT BACK IN AND THEY TOLD ME IT WAS SOMETHING I MUST HAVE DONE TO IT BECAUSE IT WAS FINE WHEN I LEFT. THEY NOW REFUSE TO FIX IT UNLESS I PAY FOR IT. LITERALLY AT A LOSS FOR WORDS..

MY CAR IS VERY SLUGGISH WHEN I PRESS THE GAS PEDAL IT FEELS LIKE MY ENGINE DOES NOT WANT TO GO, AND WHEN I'M IDLING I FEEL AS IF MY ENGINE WILL STALL UNLESS I PRESS THE GAS, I HAVE CONTACTED KIA REGARDING THIS PROBLEM AND THE ASSOCIATE I SPOKE WITH SAID THAT MY VEHICLE HAS BEEN RECALLED UNDER THE SC176 CAMPAIGN ( THIS WAS IN FEBRUARY 2019) IT IS NOW APRIL 14TH, AND ACCORDING TO KIA MY CAR IS NOT OFFICIALLY RECALLED AS OF YET.. BASICALLY I FEEL I'M DRIVING AROUND IN A TICKING TIME BOMB. . AND ACCORDING TO THE RECALL I AM, THE RECALL IS DUE TO A POSSIBLE ENGINE FAILURE AND FIRE .. MY 2015 KIA SOUL ONLY HAS 22,500 MILES ON IT ... I FEEL KIA IS ( NO PUN INTENDED ) STALLING REGARDING THIS HIGHLY DANGEROUS SAFETY RECALL.

I GET THIS ROCKING/JERKING/ FEELING IN THE ENTIRE CAR WHILE HOLDING THE BRAKE AND SLOWLY INCHING FORWARD OR BACKWARD, AS IN GOING REALLY, REALLY SLOW. THE FEELING IS WORSE THAN OTHER TIMES RANDOMLY WHILE DRIVING. FOR A FACT IT IS ABSOLUTELY WORSE WHEN THE CAR HAS BEEN SITTING OVERNIGHT AT HOME OR AT WORK ALL DAY
