2016 Kia Soul Powertrain & Transmission Problems

SUBJECT: Engine → Stall → Loss of power while driving: While driving normally, the vehicle began losing power and could not accelerate properly. The engine warning light illuminated and the vehicle repeatedly entered a reduced-power condition where it could barely maintain speed. The vehicle would stall while driving and then restart after sitting. This occurred multiple times over a period of time and progressively worsened. The engine also began consuming large amounts of oil between oil changes. Eventually the engine suffered catastrophic failure and would no longer run. A dealership later stated internal engine damage was present, including a failed valve and spark plug damage. The vehicle is currently at a dealership and available for inspection. The loss of power and stalling created a safety hazard because the vehicle could not maintain normal traffic speed and could have been struck by other vehicles. The problem was confirmed by a dealership service department. Warning lights were present prior to final failure and appeared during the loss of power events.

Safety defect P1326 code is a known indicator of rod bearing wear. When it triggered, the vehicle immediately went into Limp Mode, creating a significant safety hazard. The behavior aligns with the documented defect affecting NU GDI Engines and is not consistent with normal Engine wear. I have confirmed the KSDS software update was performed. I have taken the vehicle to Clay Cooley Kia of Plano and my service advisor has confirmed that the engine is defected per the NU GDI Engine Settlement and related federal safety actions.

I paid almost 3,500 dollars and Kia kept my car two months and I’m still having transmission issues and now they are asking for service receipts. After I picked up my vehicle from the original transmission repair I was back in less than 7 days because transmission was roughly jumping in gear and shifting horribly with burning smell. The technician noticed the problem and immediately took my car to the back but they kept my car another 30 days saying that they did an update and now I’m stuck suffering with a struggling transmission. My mpg has drastically dropped on this vehicle to a 9.6 and that is not normal. I paid cash and Kia need to help me in any way. They are trying to wait until the 12,000 mile warranty runs out and leave me stuck and that’s not fair when I’ve been complaining since I picked up the car the second time but they won’t assist me now. My Vehicle experiences delayed transmission engagement, RPM increases without acceleration, hesitation, and loss of fuel economy. Dealer refuses diagnosis unless complete failure occurs. This creates unpredictable vehicle response and loss of power concerns. Transmission hard shifts and jerks violently during gear changes and acceleration, causing loss of smooth power delivery and unsafe vehicle behavior.

Transmission failed when mileage was at 88,000 miles and is not opererational to drive. After taking car to a pirate auto shop the mechanic informed me it showed codes P0753 and P073, and informed me the transmission fluid had metal debris inside it. This is a known defect from this specific Kia model. Then took it to the Kia Dealership in Chula Vist, for diagnostic, they informed me P073 code shown up and recommended to replace the transmission. This is known defect that is associated with the Kia Soul manufacturer, and is related to the recall. My safety was put at risk when I was driving and after I stopped at a red light the car was in drive and would not accelerate when I pressed the gas, this problem was confirmed by the dealership with diagnosis paperwork. Their was no warning when this issue occurred, additionally Kia corporate refuses to accept responsibility for their manufacturer defect.

Kia 2016 died in mid traffic, would not switch out of 1st gear as an automatic, on a major road in Texas, no warning lights etc. Could be Transmission or Catalytic convertor.

Component/system failed: Engine and Power Train. Available for inspection: Yes, the vehicle is currently at the dealership. After a loud ticking/knocking noise from the engine began, the car lost power while driving. It matches symptoms associated with Kia’s known connecting rod bearing failure issue (covered under Recall SC176 and Campaign PI2002A). There were no warning lamps at first, but later the oil pressure warning light began to flash intermittently. A Kia dealership confirmed the issue and completed the PI2002A ECU update. However, they denied the extended engine warranty coverage under the campaign, saying that the vehicle was purchased at an auction, even though this issue stems from a known manufacturing defect and recall that should apply to the vehicle, regardless of ownership history. This creates a serious safety concern, as the engine could seize while driving. This issue has been reproduced and confirmed by the dealership and documented under Kia Case #25414628 and #25331856. This denial contradicts the campaign terms and puts drivers and others at risk.

We purchased a 2016 Kia Soul with the GDI engine in October 2024 from Jim Shorkey Kia in Uniontown with 60K miles on it. We just had to have a whole new Catalytic Converter installed that cost us $1500 because the one on this car was completely messed up. It caused the car to stall, have no power and when my daughter was pulling into her parking space, this caused the brakes to stop working because the car was getting NO power. The converter was completely clogged and the whole thing had to be replaced (AT OUR EXPENSE)! This was a recall for the same year Kia Souls, but somehow this one is NOT on the recall list for the exact thing that these were being recalled. How does that work? We were left without a vehicle for days and we had to pay to have the car towed to a garage and repaired. Kia would do nothing, so we had to have it repaired at a reputable garage in our area! Only having the car of less than 8 months after buying it used from a KIA dealership, this is disheartening. How could they sell a car that obviously had issues with the catalytic converter, or they did just NOT check the vehicle out before they sold it to someone. I get that it was a used car but are we seriously going to sell a car to someone that obviously has an issue! So why exactly was this 2016 KIA Soul with the GDI engine, NOT recalled?? We should be reimbursed for this. This is crazy. My daughter could have been in a horrible accident. THANKFULLY she was only leaving her apartment and in the parking lot of her home! What do we do about getting this? This car clearly has issues and should have been recalled with the others!

CATALYIC CONVERTER IS DAMAGE

The propulsion battery has so much degradation that when I drive on the freeway the "turtle" mode activated not allowing me to do freeway speeds with cars around me. It forced me to slow unsafely while cars were behind me, I had to react quickly to turn on my hazards and try to get the vehicle to speed up. If I was too slow or another driver was inattentive we would have been hit from behind by a vehicle going much faster.

I had recently acquired my 2016 Kia soul from a used dealership, and as I had gotten it, inspected by a mechanic, the back rear brake was locked. The Penrod was missing on one of them, and my driver side door lock was broken and I thought that was simple issues that could be repaired. You know that’s a used car whatever as I started driving it not even a month later I start feeling heavy acceleration when barely hitting the gas and trying to shift because it is a manual and loss of power on first and second gear, like it was going to stall out without even rubbing the RPMs to get it to move. I did some research found out that there was multiple recalls on the catalytic converter and it’s causing a fire the ECUs and also the antitheft system so I am a single mom. I work constantly and my only vehicle with 4kids, so a full month mark my Oil light all of a sudden started coming on but flickering I pulled over there’s no smell of burning oil no leaks no high temp I checked my oil stick. It was fine a thick drip on it. I Thought everything was fine, but the light still kept coming on and flickering when I would accelerate it would go off when I would decelerator push clutch in it would stay. I called kia dealer had it taken, did the recall orders on it but they told me they wouldnt do an oil check or do a code diagnostics for it unless I paid over $200 for just that diagnostics after they did all the recall orders I picked up the car over a day later. started having misfires the car was driving worse then when I took it to the dealership, i would drive up hill I’d lose power. Shifting gears from 1-4 it sounds like the whole engine was shaking like it was gonna fall out of the car I called the dealership and told them what was goin on. They were really rude to me and told me an hour later it was throwing codes of misfires an again have to pay for it, they stated the oil an misfires werent their fault doin the recalls. ECU an ANTITHEFT, I am worried for my kids safety!!!!!

I put the car in park, and exited the car to do something, and it started to move forward on its own. I jumped back in the car and stepped on brakes, and shut the engine off. I was to the side of the car, so did not get injured. On a different occasion I was parking the car in the carport, and put the car into park. When I released the foot brake, the car started moving forward on its own again. I put on the brake, put the car into reverse to reverse to the parking spot, put the car into park and put the parking brake on. Others were around the car, but not directly in front of the car so no one was injured. The car has not been taken to the dealer yet for this issue, not has anyone inspected it for this problem. I have an appointment soon for an inspection by the dealer. These incidents happened without warning.

There is an active recall on 2016 Kia Catalytic Converters. I was told my VIN is not included, even though I have this make and model. The car consistently struggled at 60 MPH, and was driving rough at lower speeds, but randomly. I had to travel no more than 45-50 MPH. This was dangerous since i was on the Highway when the car started to struggle at 60 MPH. Kia said my Catalytic Converter is clogged and not fixable, I needed a new one. The car only has 80K miles, I bought it Certified from Kia.

Bought 2016 Kia Soul one year ago (May 2022) with 79k miles. Feb 2023 engine light came on. Took it to Kia service center & they reset it and told us to come back if light came back on. It did along with oil change light (June 2023, 92k miles). We were told it had no oil, it was consuming oil, sludge in motor and there was nothing they could do. Service mgr told us to check oil level regularly, top it off as needed and get regular oil changes and if/when it failed, then they would replace engine under new lawsuit settlement (extended warranty to 15yr/150k). We consulted another mechanic and he said it is faulty piston rings that caused oil consumption, that caused low oil and that ultimately caused possible sludge. Why aren't they fixing the problem instead of waiting until the engine fails? Probably because they were waiting to see if your engine fails after 15yr/150k mile warranty expires. New lawsuit in the works regarding oil consumption because it's happening to a lot of KIAs.

The contact owns a 2016 Kia Soul. The contact stated while driving 30 MPH, the vehicle vibrated violently and lost motive power. The contact stated that while accelerating, the vehicle failed to exceed 10 MPH. The check engine warning light was illuminated. The vehicle was taken to the dealer however, the mechanic failed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 73,000.

The vehicle contains a defect related to motor vehicle safety or does not comply with an applicable federal motor vehicle safety standard ENGINE REPLACED THRESHOLD REPLACED CATALITIC CONVERTER BLEW ECU COMPLETED AIRBAG WARNING DOES NOT CLEAR INACCURATELY REPORTED/ COMPLETED VEHICAL MALFUNCTIONING LOSS OF POWER

It been buckling at low speeds, acceleration is not consistance with how much gas I press. If I have the car at stop sign or red light. It completely stalls out with the battery and oil light comes on. This happen 5 times in a 40 minute drives it would have happen more if I didn't notice it was happening cause of the issue was going on at lower speeds. I notice the heat was higher, also was fumes coming into the car while on highway. There was a moment where the car started to stall on highway, but quickly regain. Very stressful and dangerous situation.

1. On 1/30/23 I was heading home from work when my engine and oil light came on. I after parking at turning my car off, the engine began to shake and make clicking noises continuously. I got an oil change that day thinking that may help the issue. On 1/31/23 I took my car to another mechanic who notified me that they have seen many Kia Souls and Optimas with this problem and many engines have been recalled. Upon my way home which was 2 miles away, my engine entirely blew up on interstate 15. 2. My safety was put at risk by my car engine blowing up on the freeway and losing power within seconds as traffic was going at 70 mph. I then ended up right in front of an on-ramp and had a small area to park at as was within 1 foot of oncoming highway traffic for 30 minutes - in freezing temperatures. Something also blew out from under my car and almost his a vehicle behind me. 3. Kia stated this has been an issue and that I need to take it to a Kia dealer for inspection. 4. My vehicle has been towed to Young Kia of Layton UT for inspection.

Check engine light came on and I had it read. It came back as P050A - Cold Start Idle Air Control System Performance. I saw online that there is an existing service action fix: SERVICE ACTION: 1.6L GDI WITH MIL ON DTC P050A ECM LOGIC IMPROVEMENT (SA485). The dealership informed me that although my car is a 2016 Kia Soul it isn't part of this service action. However, seeing as how I am getting the check engine error code associated with this service action fix, I believe that my vehicle SHOULD be included.

On 12/27/22, was driving on highway in the evening, engine light illuminated and vehicle slowed down and unable to drive beyond 40mph. Was able to make it home safely, notified dealership on 12/28/22 and used AAA service for vehicle tow. Recv'd call from dealership on 1/3/22 that vehicle was inspected and was ready for pickup. Issue was code P1326 related to KSDS (knock sensor detection system) & connector rod bearings, so they did an ECU update & bearing clearance test. (While waiting for info I did online research & learned of the issue with KIA's GDI engine failures/fires). I asked dealer rep if the issue with my vehicle was related to this and was told yes, that this was the first step in Kia's protocol for the issue. I raised concern over driving the vehicle knowing that there is a possibility of engine failure or fire. He acknowledge the concern, but reiterated that this was all they would do for now. I asked for a copy of the repair/service protocol and was told he would try to get me one. Am scheduled to pick up vehicle in a few hours and am sure there will be more issues & concerns to follow.

I purchased my vehicle back in 2021 and I notice that the recall for the catalytic converter so I check my car reports and don’t see where it was replaced or service I recently went to get a check engine diagnostic and the code read p0420 which is problems with catalytic converter no one has been the owner of the vehicle since 2018 and I’m not sure if it was replace or replace incorrectly I shouldn’t be experiencing difficulties and I haven’t reached over 100,000 miles since the previous mileage @ the timing of the recall “fixture”
