2021 KIA SOUL Power Train Problems

The transmission on the vehicle has gone bad twice since we purchased it used. The car has 34,400 miles on it. The problem puts the driver in an unsafe situation as the problem causes the car to lose power while at high speeds. The piston rings have also been replaced as part of the recall. Kia just keeps replacing these parts with more defective parts. I have videos if you want them.

The contact owns a 2021 Kia Soul. The contact stated that the vehicle experienced a transmission failure, and the transmission was replaced by the dealer. The contact stated that the dealer also replaced the rack and pinion due to an abnormal clunking sound coming from the steering wheel. Additionally, the contact stated that the vehicle was experiencing abnormal oil consumption. The vehicle was taken to the dealer, where an oil consumption test was performed. The contact returned to the dealer after driving for 1,000 miles on three occasions. The dealer determined that the vehicle was not experiencing excessive oil consumption. The dealer replaced the motor mounts. The contact related the abnormal oil consumption to NHTSA Campaign Number: 21V259000 (Engine), which was previously performed on the vehicle. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 4,815.

[XXX], the vehicle was delivered to Crain KIA dealership located in Conway, Arkansas, due to failure of engine to start (engine would turn over but not run). I scheduled a service appointment for May 20th at 0930, for the car to be evaluated/troubleshot. While at the KIA dealership service desk, I discussed KIA SAFETY RECALL SC336, and that my VIN# was effected by the recall (verified by speaking with KIA Customer Care representative) and by using NHTSA's VIN/Recall search engine. At that time, I disclosed that the car was a SALVAGE TITLE vehicle, but was restored, looked nearly brand new and was otherwise operational prior to the engine "no start" condition (4 months of ownership). The service team at the dealership confirmed the SALVAGE TITLE via "Carfax", however they noted that KIA's internal VIN/TITLE database DID NOT REFLECT the car as salvaged. Crain Kia dealership then decided to submit the...

Our 2021 Kia Soul experienced complete engine failure without warning. The engine suddenly lost power and became inoperable while driving. The dealership's diagnostic testing identified a camshaft sensor code, but no definitive cause for the catastrophic failure was provided. We believe the failure is related to internal engine damage potentially caused by defective piston oil rings, consistent with NHTSA Recall Number 25V099000. Kia has not conducted a full internal engine inspection to rule this out. The vehicle is in Kia's possession and is available for inspection upon request. The sudden engine failure occurred without warning and caused a complete loss of power while the vehicle was in motion. This could have led to a serious accident had the incident occurred in heavy traffic or on a high-speed roadway. The inability to accelerate or maintain control of the vehicle poses a serious safety risk to both the driver and others on...

I dropped off my 2021 Kia Soul at the dealership where I purchased it to address a nationwide recall, which states: “The piston oil ring(s) may have been incorrectly manufactured, potentially damaging the engine cylinder wall. This can lead to increased oil consumption, abnormal engine noises, engine seizure, and possible fire from oil leaking onto hot exhaust components. Loss of drive power and/or fire increases crash and injury risk.” My vehicle has shown multiple symptoms, including rough running, significant shaking, illuminated check engine and oil lights. On 01/02/23, I brought it in, but the dealership found no stored codes and took no action. On 04/20/23, a code for a cylinder 1 misfire was found, but because the issue wasn’t present at that moment, no repairs were made. On 10/05/23, spark plugs and fuel pump were replaced under warranty. No further issues occurred until 02/14/25, when the same symptoms returned. I...

1.) We were driving to Nashville and once my car got around 70,000 mile my check engine light came on. Then my car started to make a humming noise. We pulled over to check the oil the oil was fine. Once we got back into the car and left the gas station the light started to blink. Yes 2.) We were on the highway, and if the engine could have blown up or we could've got stuck on the way there and back. Also, the where the car started to act up was around a bad neighborhood. 3.) Yes 4.) Yes 5.) The car started to hum but once my car hit 70,000 miles the check engine light came on and started to flash.

The vehicle experiences a complete loss of power when slowing to a stop before it powers off on its own. The car powers off while going down the road. The car experiences partial loss of power while on cruise control and the car will slow to nearly stopped. The immediate loss of power puts myself and others at risk as the car is now stopping unexpected on the highway. I have left numerous voicemails for service managers at the dealership it was purchased brand-new from 2 years ago. They have not reached out to me. I had an appointment at their dealership to have the car inspected to see if this was covered with my warranty and they explained my warranty was only 60k miles and my car is now at 65k miles. The car was shutting off and having power loss a week before the first indicator light came...

My vehicle at three months had transmission failure like many 2021 Kia souls after the repair I began to experience, mini electrical issues and steering issues which are very common for this model year. Most recently I have taken it in for electrical issues.

In April 2023 I purchased a 2021 Kia Soul. I had no issues at all with my Used Kia Soul. In Nov 2023 I was in an accident. I hit a deer and that did cause damage. My insurance company fixed it. I got my car back in Dec [XX], 2023 with approximately 96,000 miles on it. A few days later on my way to work. I entered the highway the car was running fine at 70mph then all of a sudden it lost power.. No power in the middle of the busy Atlanta Highway!! I was able to coast onto the shoulder. At that point I turned the car off. Turn the car back on to see if I was able to get it into Drive. Unfortunately that didn’t work my car didn’t move at all. I had to call the tow company get it towed back down to...

The contact owns a 2021 Kia Soul. The contact stated that while driving approximately 50 MPH, the vehicle lost motive power and stalled. The vehicle was later towed to the local dealer who diagnosed the vehicle and determined that the transmission and the engine had failed, and both needed to be replaced. The vehicle was not yet repaired. The contact was informed that the VIN was not included in NHTSA Campaign Number: 21V259000 (Engine). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 109,000.

We were traveling on the freeway 70 mph surrounded by heavy traffic at night, the vehicle started surging and bucking, shaking violently. The rpm's swung wildly from 2000 to above 3500 and car started to decelerate quickly in heavy traffic. I was able to get the car into right lane but feared being rear ended due to speed falling abruptly. Even though accelerator was being depressed and engine running car would not go and loosing power fast. I was able to turn off at an exit and there was just enough enough power to make it up a slight hill and turn right onto a round-a-bout where the vehicle would no longer move, abruptly stopping the fast traffic behind and again fearing a rear end collision to us. The engine produced power but nothing going to wheels, it was as if vehicle was in neutral no matter where the shift...

I was on the freeway, and the car was shuddering a bit before I lost the ability to accelerate. It would rev but no power to the wheels. Had to pull over and get towed to the dealer. I think it may be a transmission failure.

I bought my 2021 Kia Soul on 10/21/20. Then on 11/11/20 my car started having transmission issues within less than one month of ownership & nearly 1000 miles on it. The transmission was replaced in late Nov./early Dec. of 2020. On 12/15/22, My Soul started revving up & the RPM needle was bouncing while driving, but the car would not go any faster when I pressed the gas pedal. I realized, I was having transmission issues with my 2021 Kia Soul, AGAIN. The car has less than 37,500 miles on it. I contacted Power Kia of Salem Oregon that day & the first appointment that I could get was on 12/29/22. I had the car towed to Power Kia on 12/27/22, then received a voicemail & text msg. from Power Kia on 12/28/22 that they will diagnose the issue. That was the last time that I got any information about...

I own a 2021 Kia Soul with 34,130 miles. Purchase brand new in 5/21. I just had it serviced on 2/3/23. On 2/10/23, I was driving toward home on I-40 east, near mile marker 418 and the rpms suddenly started to jump up and down from 1000x to 6000x and the car had no ability to go anywhere close to the speed limit. There was a whistle noise coming from under the car. I took the I-81 north interchange to try to get the 80 or so miles back home but could not get the vehicle to go more than 15 mph. I was terrified I was going to get hit by the 18 wheelers whizzing by me. I got in the break down lane and limped to exit 8. The car began to shake violently and barely move. I got off the exit ramp praying no one would rear...

The engine is consuming increasingly high amounts of oil with no leaks, far surpassing the one quart per 1000 miles. Oil pressure lamp has illuminated on 1-2 occasions, only briefly, and shortly before I took it to the dealership. Unusual noises coming from the engine while accelerating and also after I stop. I had my oil changed 1 week ago, unusual noises have not improved. Currently awaiting inspection at the dealership for manufacturer warranty coverage for repair of this issue, but seems to have all the earmarks and the production date (9/20) that line up with the piston ring recall, though they say my vehicle is not covered by the recall.

The vehicle started loosing power. the engine would rev up but the car wouldn't go. the car had to be towed to the dealership because the vehicle would not engage into drive or reverse. the dealership is replacing the transmission. It is the IVT transmission

I I WAS ON THE INTERSTATE AND MY CAR STARTED MAKING A LOUD NOISE AND DECELERATED. IT SEEMED TO LOSE POWER, I TURNED AROUND AND STARTED HOME AS I WAS VERY FRIGHTENED. THE CAR ACCELERATED WITHOUT PRESSING THE GAS, DECELERATED WITHOUT PRESSING THE BRAKE. THE TACHOMETER WAS SWINGING AROUND WILDLY. THE CAR MOST OF THE TIME SEEMED TO HAVE NO POWER. I WAS AFRAID OF A REAR END HIT BY ANOTHER CAR OR FLYLING INTO THE BACK OF THE CAR IN FRONT. I WAS TRYING TO LIMP IT IN TO THE DEALER. THE CAR ONLY HAD 3400 MILES ON IT AND I HAD HAD IT FOR 7 MONTHS. AT ONE POINT I HAD TO STOP FOR A RED LIGHT AND THE CAR WOULD NOT MOVE. I PUT ON THE WARNING FLASHERS AND TIRED TO EDGE TO THE SIDE OF THE STREET AS THERE WAS A BIT OF SLOPE. I TURNED...
