2021 KIA SOUL Complaints

While driving, the vehicle began running rough and stalled shortly after. It would not restart. The vehicle was towed to a dealership, where they diagnosed “excessive cylinder wall scoring” and no engine compression. This matches the symptoms described in Recall SC336, which affects piston oil rings and can lead to engine failure, stalling, or fire. The dealer confirmed the engine won’t turn over and compression is lost, but they refused to perform the required piston ring inspection under the recall. They stated I would need to pay for an engine tear-down first. However, according to the recall remedy, the inspection and engine replacement should be performed free of charge if symptoms are present. The issue occurred without warning, leaving me without transportation and unable to safely pick up my child. I have opened a case with the manufacturer and am awaiting their review.

Engine burns oil irregularly and quickly. In October 2022, the check engine light was on and stalled while driving. Kia dealership in Sioux City stated my vehicle was not part of the original recall. The car was under warranty and they kept it for nearly 2 months to repair. Vehicle started stalling again last winter. Was told mice ate wires per dealership. In June 2025 - oil still burning quickly despite getting on time and regular oil changes. This time while driving on the interstate the check engine light came on again. Went to my local mechanic immediately (Car is out of warranty per mileage 85,000) and I hate the dealership - bone dry oil. They are convinced it's the pistons. Called the dealership. They made me call Kia. Kia claims my vehicle is not effected by the updated April recall - but they could repair my...horn. This car is dangerous. It constantly makes a knocking sound. I check the oil twice a week and have to add oil accordingly like it's a 1978 Buick. If this car stalls out while I'm commuting to work on an interstate, I and others could be seriously injured.

Saw that there was a recall for faulty oil piston rings on my Kia 2021 soul received the letter from Kia in mid to late April made the appointment with Coughlin Kia of Newark for May 5. Coughlin Kia canceled it on May 4 June 24 had to have my Kia towed to Coughlin Kia of Newark June 20 27. They said Oil was going through my piston rings. There was vertical scoring on the cylinder walls, but they said that it was not because of the recall and I would have to pay $7000 to fix it even though I hid made the appointment and they canceled it. I had talked to Kia manufacturing in late February and had them record my call and ask them what do I do in the meantime because my Kia is burning a lot of oiland their response was we don’t know now I have engine failure and they’re claiming that they won’t fix it, even though it is under the recall.

Recall by KIA for engine malfunction--website/nhtsa shows multiple recalls, issues & motor replacements due to Piston Oil Ring issues that could result in stall or fire; had 2 recall dealer inspections citing need for camshift replacement, & SC336 Piston Oil Ring failure. Engine has used excessive oil (now 3+ qts in 3000 miles) which nhtsa lists as issue with the engines--recall was issued for this engine 2/17/2025, letters sent 4/4/2025 which I never received, oil consumption occurred over years/months. Techs at dealer told me operation of the engine "can be detrimental". KIA refuses to replace or repair the engine--this has been noted by nhtsa. Independent testing (2) indicates camshaft and crankshaft sensors are not in sync. I am fearful to operate the vehicle due to danger of stalling and/or fire, which could cause crash or injury. I ask for NHTSA to enforce their directions to KIA and replace the engine.

Unusual engine oil consumption. Engine using 1 quart of engine oil every 1000 miles. Not normal.

I took my 2021 Kia Soul to Kia of Leesburg here in Florida, and dropped it off yesterday June 17th, per service department request and was told that they were going try to repair the multiple recalls on this vehicle. They told me that it was going to be 24-48 hours before I was going to be able to get it back when I called, regarding my safety critical recall. So, I dropped it off last night as instructed, the KIA of Leesburg service department called me today stating that due to sludge in the engine, they're refusing to fix the recalls, and stated that I owe them $200 before I am able to pick up my vehicle

The contact stated that a recall appointment with a local dealer was scheduled; however, while driving to the dealer the check engine warning light illuminated. The contact stated that the vehicle stalled while at the dealer. The dealer attempted to restart the vehicle and then ran several tests on the vehicle.

my vehicle was part of a recall for the piston oil rings. the car was taken to KIA for testing. The car failed the test and I was told that the engine would need to be replaced (I have a video and test results of the failed test. Then KIA stated that too many cars were failing and that they were redoing the test. My car was in the Kia repair shop waiting for an engine that was ordered. KIA cancelled my engine and my car was tested with the new test and it passed. After two weeks of being in the repair shop I was told to come and get it. This not only appears unethical but a blatant attempt to circumvent the recall.
