2012 Kia Soul Engine Problems

Check engine light came on. Car starts to shutter upon acceleration as well when its idling. Changed spark plugs 3 times since Jan 2025 and coils twice. Code for engine misfire in cylinder 3. Also have to add oil every 2 weeks.

On 12/ 22/ 2025 I went to start the 2012 KIA Soul and it would act like it would start but, it would not turn over. Battery was fine checked it. Let it set a moment and tried it again would not start. Called a wrecker and towed it in. The service guy tried and couldn't get it to start either. He ran a diagnostic on it, there were not type of codes, no check engine light nothing. He had it for until 1/5/2026 and when they went to check it it started right up. They drove it for 20 miles to check to see if it would cut off while driving, it didn't. It starts now but for how long. Here's the strange thing, I drove it 20 minutes away and I noticed that the counter for when You fill up with gas states how many miles you have left to go before fill up was counting UP not DOWN. So I think it could be the computer or electrical, I thought it was the fuel pump at first. Still no warning signals nothing.

P1326 code followed by loss of power (limp mode) followed by multiple misfires and loss of compression in cylinder 2. Loss of power going up a hill on interstate with a full car one under age 10. Dealer and firestone states no compression in cylinder 2 and says needs engine.

On Oct. 14, 2025, this vehicle experienced a sudden catastrophic engine failure while driving approx. 70 mph on a highway. While in the passing lane, the vehicle began to lose power, shake, and wouldn’t accelerate. The check engine light came on just moments before a loud explosive noise came from the engine, and a burning smell came through the vents - the engine completely shut down. This failure occurred with other vehicles on the roadway, creating a serious safety risk. I was forced to quickly maneuver the disabled vehicle across multiple lanes of traffic to reach the right shoulder, where I called for roadside assistance. The vehicle was inoperable from that point forward, it would not turn on, and was towed from the scene. There were no warning signs prior to this event. The vehicle had been operating normally before the incident - I had recently checked the oil levels, there were no warning lights, no drivability issues, and no known mechanical problems before the sudden failure. This led me to find the vehicle was subject to an open safety recall addressing engine damage consistent with this failure; NHTSA Recall 19V120000. On Oct. 27th, the vehicle was towed to an authorized Kia dealership in Prescott Valley, AZ for recall inspection. The dealership advised the connecting rods failed and blew 3 holes through the engine block, confirming catastrophic internal engine damage. The manufacturer required a recall-related software update be performed before reviewing the engine failure under the recall. The software update was completed in Nov., but the manufacturer later declined to repair or replace the engine. Kia Corp. refuses to address the safety recall entirely, and instead repeatedly mischaracterizes the issue as a warranty matter - they are unwilling to provide a written explanation of how the failure falls outside the scope of the safety recall 19V120000, despite the failure matching the recall’s described defect & consequences.

Took car in for recall SC176 and was told by Taylor Kia in Lima, Oh that what was happ wasn't throwing a code. Said they fixed the knock sensor and that if it is that problem it would go off and they could check it again. My car ran worse than before getting it back. What is happening to my engine is exactly what is detailed in the recall. I drove home 35 minutes shacking and knocking the whole time and no engine light? You can hear the rod knocking in my engine. Exactly how it is explained in the recall. So, now I'm stuck with an engine that going to be ruined when the rod does flys out. Hopefully not harming me or anyone else. This is ludicrous and poor work done.

The contact owns a 2012 Kia Soul. The contact stated while driving at an undisclosed speed, the contact heard an abnormal chain rattling sound. The vehicle was taken to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was informed that the failure was due to the unrepaired recall of NHTSA Campaign Number: 19V120000 (Engine and Engine Cooling). The contact stated that the recall notification was never received. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 135,000.

I got the recall SC284AM - HECU FUSE REPLACEMENT Done. As soon as I started the engine at the Kia dealer thick smoke started coming out of the exhaust pipe. When I showed it to the dealer they said it has nothing to do with the fuse replacement. The car was perfectly fine before the fuse was replaced. To check out the reason for this the dealer is asking $300. It’s definitely the result of the fuse replacement. Need help.

I was driving and my check engine code went on , I got it checked by autozone and it was for the catalytic converter. My car has since ran horribly, there feels like a lag in acceleration and it makes a hissing/air noise that comes from the catalytic converter it gets overheated and causes my car to go in limp mode and when I asked a mechanic friend they said it’s very clogged which has caused me to park my car and not drive it because I was recommended to not drive it being in this condition then I was send a recall in email. It has one owner and we have kept up with maintenance very well.

I took my car to a local place to get the oil changed. The person would not touch anything with my car until I had it looked at by someone at the local Kia location. There was a knocking sound, which seems to get worse when accelerating, or going up hill. I get it to the local Kia location, and they take a look at it, said it was out of warranty, the engine was about to go out, and there was nothing they could do. They also stated, they were surprised that the engine hadn't already gone yet.

Transmission is going out. Valve and piston issues.

The contact owns a 2012 Kia Soul. The contact stated that while her daughter was driving approximately 60 MPH, the check engine warning light illuminated, and the vehicle stalled. The contact stated that her daughter was able to pull over, restart the vehicle, and drove back to her residence. The contact stated that the vehicle was no longer able to be started. The contact called a dealer who requested that the vehicle be towed to the dealer for diagnostic testing. The vehicle was not diagnosed and was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 135,000.

I saw a puff of smoke then the engine started knocking while I was driving, I had the car brought home and I called Joey Griffen dealership and they told me it will be a four month wait that I would have to come out of pocket $7000 to have it fixed, that's when I found out about the recall I should not be coming out of pocket for something totally out of my control I saw metal parts on the ground, the car started knocking a few seconds after seeing smoke under my hood, it literally came out of no where

My car died while driving it down the highway. And I couldn't get it drive. I had to have it towed.

I have contacted KIA Corp. and advised them that my 2012 KIA Soul ! with 146,500 miles was consuming so much oil that the KIA dealership had to replace my engine for $5000 and that I had to pay it. Why won't KIA Corp reimburse me? It is under 150,000 miles. They advise me that they would pay a Good Will fee to me and never did !!! The KIA dealership always did my oil changes on time and have records of them. KIA Corp should reimburse me for a GOOD WILL FEE.

The car experienced a sudden catastrophic engine failure. We had just pulled out of the driveway and were on our residential street, so there was no accident, we were able to pull over and stop the vehicle without incident. It was towed to the Kia dealer (Premier Kia of Carlsbad 5331 Paseo Del Norte, Carlsbad, CA 92008). After detailed inspection by one of their service technicians they determined that the cause of the engine failure was the same connecting rod bearing failure that other years/classes of Kia Soul have experienced. The dealer initiated a claim with Kia to try to get the extended warranty and engine replacement covered for my vehicle since it was exactly the same issue they have seen with the vehicles covered in the legal settlement (Techline case #15756680). However, Kia has denied responsibility for what is clearly a defect in the engine affecting other Kia owners not currently being reimbursed for their loss by previous recalls and legal settlements.

The contact owns a 2012 Kia Soul. The contact stated while driving 60 MPH, the engine was misfiring. The check engine warning light was illuminated. The contact veered to the side of the road for 20 minutes. The contact stated that he turned off and restarted the vehicle, and the vehicle responded as needed; however, the check engine warning light remained illuminated. The contact stated that the failure recurred a week later. The vehicle was taken to an independent mechanic, where it was diagnosed that the catalytic converter had failed and needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 19V120000 (Engine, Engine and Engine Cooling); however, the VIN was not included. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 149,000.

I was driving at night down a major highway when the car stopped dead. I towed it to a repair shop and they told me that the engine was completely gone. They informed me that there was a class actions case on Kias due to engine failure. I need my Kia to have the engine replaced and covered under this situation as it totally does not work anymore and from what I am told it is a catastrophic occurrence happening to many, many Kias. Who can I contact about getting this fixed?

The contact owns a 2012 Kia Soul. The contact stated that while driving at approximately 5 MPH the braking system suddenly activated causing the vehicle to abruptly stop. Smoke was then seen coming from under the front end of the vehicle. After the contact exited the vehicle flames and smoke began to engulf the vehicle. The fire department was called to the scene and extinguished the flames. The vehicle was later towed to the home. The extent of the damage to the vehicle and the cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The failure mileage was 190,000.

Engine seizure, stalling, engine turns off without any warning. When taken to dealership or mechanic there is no error code for the issue.
