What 976 owners told NHTSA about the 2014 Kia Sorento Phev

On XXX, the 2.4L Theta II GDI engine on our 2014 Kia Sorento (current mileage: 160,000) catastrophically seized without warning while my [XXX] was driving at interstate speeds at night. This caused an immediate and sudden loss of power, power steering, and braking assist, creating an extreme traffic hazard. No one was injured and the driver was able to safely coast to the shoulder, but it created a highly dangerous situation on a busy interstate. We had the vehicle towed to an independent mechanic who pulled the starter and confirmed a total mechanical engine seizure. The vehicle was then towed to a Kia dealership. This vehicle has suffered from the well-documented Theta II factory manufacturing flaw where debris destroys the connecting rod bearings, leading to high oil consumption and sudden highway seizure.

My high pressure fuel pump is spraying fuel in my engine. This is a new engine replacement as of October 2024. This is a huge fire risk and we cannot operate this vehicle.

The vehicle's original engine suffered severe oil consumption and a blown head gasket, which contaminated the exhaust system. The Kia dealership replaced the engine under warranty but refused to replace the damaged catalytic converter claiming it wasn’t a part of the warranty even though it was consequently damaged. The dealership explicitly stated the vehicle should not be started or driven due to the blocked exhaust, but then did repair and release after I pushed for the catalytic converter replacement. They said I would have to follow up with Kia corporate. They released the unsafe vehicle anyway and I have been following up with Kia customer service for 2 months to request a CAT replacement. While driving, the blocked exhaust caused a severe rattling noise, immediate engine overheating, and complete mechanical engine seizure. The engine completely cut power and locked up while in motion, creating an immediate crash hazard on the roadway. The vehicle is now completely inoperable and will not turn over. This is a severe safety defect where a known blocked exhaust system directly caused catastrophic engine failure while operating.

To whom this may concern: This is what I sent to KIA which I was informed to contact KIA customer care via phone. Which I will do but I know of several people that have had the same issue as me with a Sorento. I am writing this in regards to my 2014 KIA Sorento VIN: [XXX] I purchased in November 2021. At time of purchase it had 89199 miles, I kept up routine maintenance as usual then May 2022 while my husband was driving down the interstate the KIA shut completely down. He tried to start it back and seen a warning display on screen. We then had it towed to KIA in Morristown,TN for them to inform us that the motor needed to be replaced. That this was an ongoing issue with this make /model of vehicle. Luckily I had extended warranty that I purchased through Farris auto when I financed the KIA. They covered the replacement of the motor with 65000 miles along with a couple other things at that time. So the replacement motor was installed by July 2022 I haven’t had any issues with it until September 2025 I had the exact same thing happen to the second motor that happened to the first while my husband was pulling into driveway. I tried contacting the warranty company and of course there was nothing they can do. I contacted KIA in Morristown TN and Knoxville TN spoke with someone in the service department and nothing they can do. For this to be a known issue with Kia Sorento why can I not get the motor fixed? I don’t know where or how to find out if the motor that was replaced is in the recall list but it seems to me that KIA as a company would stand by their product. I am still paying on a vehicle that I can’t even drive, just so it doesn’t hurt my credit. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car burns oil to the point it requires 1 qt/500 mile. Had oil consumption test when issue first started in 2024 by kia, was told there was no problem. Car has continued to have this issue and has now broke connecting rod due to engine starvation even through the oil is to the full mark. I lost all power while driving with no warning before hand. Kia has admitted these engines have oil consumption issues that can lead to this exact problem and many other consumers have complained of the same situation in which Kia will not replace the flawed engine.

1. The engine consumed its own oil and a rod bearing failed and destroyed the engine 2. This happened while my wife was traveling on I20 at 70mph and almost resulted in a wreck when the engine died and she lost power to the wheels 3. Nalley Kia in Lithonia, GA has confirmed that the engine consumed its own oil which cause a rod bearing to fail and ultimately led to the engine failure 4. No warning lights prior to this happening, just a knocking sound as she merged onto I20

Re: Formal Complaint – Repeated Engine Failures and Unacceptable Service Delays Vehicle: Kia Sorento 2014 VIN: [XXX] Purchased: Fall of 2021 Current Issue: Vehicle in service at Kia of Lincolnwood since January 9, 2026 Dear Kia Consumer Affairs and Legal Department, I am writing to formally document my severe dissatisfaction with the repeated engine failures in my Kia vehicle and the complete lack of communication and urgency from both Kia of Lincolnwood (6750 N Lincoln Ave, Lincolnwood, IL 60712) and Kia's consumer support channels. This has caused significant financial hardship, disruption to my family and work, and eroded any trust in the brand. I purchased this vehicle approximately 5 years ago through CarMax. Within that time, the engine has died or stalled three times: The first failure occurred about one year after purchase, stranding me at 11:00 p.m. in rural Wisconsin during winter with my three young children in the vehicle. The second incident happened in downtown Chicago (River North), just one hour before I needed to depart for a work event in Champaign, IL, requiring a tow and last-minute rental arrangements. The most recent failure occurred at approximately 4:30 a.m. after leaving my music studio, necessitating another tow and a $50 Uber ride home. Eleven months ago, Kia of Lincolnwood replaced the knock sensor under a one-year recall warranty. Despite this, the engine issues persisted. On January 9, 2026, I brought the vehicle to Kia of Lincolnwood for the third major engine-related failure. It has now been in the shop for nearly six weeks with no meaningful updates on diagnosis, repair timeline, or resolution. I have called the dealership at least ten times seeking callbacks from my assigned service advisor (Max) or any team member. In each instance, I was either hung up on, placed on hold for over an hour, or promised a return call that never came.

We do our oil changes routinely. We had one done not too long ago. We were driving to the store and all of a sudden the oil light came on, but the engine light never came on. And then about 30 seconds later, we heard almost like a thump sound like we had hit something but we didn’t. We pulled into the grocery store parking lot about a minute after that, and there was oil leaking out of my car. We tried to put more oil in, but it just kept coming out. We have tried to see what’s going on. We can’t tell. We plan to get it towed and looked at. I don’t know if it will turn back on because I didn’t want to risk it and my engine locking up, but this seems to be an issue as I have read some of the other complaints.

While driving at low speed and turning, the vehicle experienced a sudden loss of power accompanied by engine knocking. The engine stalled and would no longer operate normally. The vehicle was inspected by a mechanic, who found metal fragments/shavings in the engine oil, indicating internal engine damage. The engine is now inoperable and has effectively failed. There were no warning signs prior to the failure other than the knocking noise immediately before the loss of power. This failure occurred suddenly and without driver input. The sudden engine failure caused a loss of propulsion while the vehicle was in use, creating a potential safety hazard for occupants and surrounding traffic. The vehicle required towing due to engine failure. Kia Consumer Assistance was contacted regarding the engine failure. I was informed that no recalls apply to this VIN and that the vehicle is out of warranty. Kia Consumer Assistance stated they would not inspect or document the engine failure unless I paid out of pocket.

I got my car fixed and I’m still having the same issue. Seems like they just turned off the lights on my car and it’s still giving me issues..

The car engine started on fire while I was driving after all the recalls were fixed and new engine installed. The car was completely destroyed the whole engine compartment was completely burned. Kia says it was an oil leak but that’s not true the car oil change was done regularly and was serviced within 3 months of the engine fire. I also had this vehicle parked inside my garage for 5 years and not a single drop of oil in the garage floor. Kia is also refusing to send me a full report of their findings from the fire inspection. Kia adjuster is acting in bad faith by not providing the fire report. The car engine was replaced new due to an earlier recall and within 10,000 miles the new engine caught fire. They don’t want to be liable for this engine fire but cars don’t just burn without any reason. The refusal of KIA adjuster to release the findings in the fire inspection is very concerning to other people driving this vehicle in the public. Where engine fire can cause their deaths and their families deaths. This is a safety problem

We financed this 2014 Kia Sorento LX AWD from a used car dealer, and there has been nothing but problems with this vehicle. From the water pump, to insanely high oil consumption. I have verified that it is not leaking. Gaskets have been replaced, filters have been replaced, O2 sensors have been replaced, the water pump housing unit, impeller and pulley have been replaced, Spark plugs have been replaced and their boots, fuses have been replaced and renewed, even the brake light switch has been replaced. The coolant thermostat has been checked and it is functional, the MAP sensor is functional, the catalytic/exhaust manifold has been replaced, the in tank fuel pump/fuel sending unit has been replaced and the HPFP has been replaced and this vehicle still wants to consume oil like crazy and is flirting with deaths door step. It goes through fits of loss of power during acceleration in times when it really matters most, like trying to pass a vehicle. So most of the time I dont, because its not safe to try to pass vehicles and suddenly lose power and end up in a collision. I have checked all 6 recalls that have been opened and closed on my vehicle and part of me wonders if they were falsely closed. One of them indicates I should have had a partial, if not whole engine replacement at some point and I still have a VIN original engine in my vehicle. I have had this vehicle in my possession since August of 2025, and have done nothing but pour money into repairs on it, and i STILL feel like its going to leave me stranded on the side of the road. KIA needs to make good on their own warranty with as many issues as this year and model of vehicle that it has, and reinvestigate this vehicle. I believe the recalls on this vehicle were closed by a shady mechanic. Mind you, before it bought this vehicle, I had a mechanic look over it with an OBDII and no codes popped, none were stored and to this day, there still are none, but this engine is not behaving the way it should.

Engine light was on about a week prior to taking it to the dealer for inspection. Was not time yet for an oil change. Had another 1000 miles before next oil change was due. After oil change they found metal shavings in new filter and oil. Told us we need to replace the engine. So we have a defective engine.
