2013 Kia Sorento Engine Problems

On December 21, 2025, my vehicle experienced abnormal knocking/ticking sounds coming from the engine while driving on the interstate (60 mph), and it was difficult going up hills. The check engine light was intermittingly blinking, and there was a strong burning smell. The vehicle was taken to AutoZone and the code displayed P0304 indicating a cylinder 4 misfire. The spark plugs were replaced. However, the knocking sounds, blinking check engine light, and smell of burning happened again, and I took it PepBoys on December 26, 2025. After testing, they indicated that the fuel injector was cracked and fuel was found in the engine oil. I had AAA tow the vehicle to Cochran Kia [XXX] ). The dealership indicated that they would not be able to look at the vehicle until December 29, 2025. The dealership verified that the check engine light was still on and the motor was misfiring badly. They then checked cylinder #4 with a borescope and found that the valve had a crack in it and that the engine would need to be replaced. There was also damage/scoring to the piston and cylinder wall. The dealership corresponded with Kia (Case #25769914), Kia however indicated that there was no powertrain warranty and that this would not be covered under PI1803 and indicated that only applies to bearing failure, and that dealership should provide me with cost estimate to replace the engine. My vehicle has been properly maintained, and I provided the dealership with the additional requested maintenance records on February 14, 2026. I reached out to Kia Customer Care and they indicated to get the engine replaced under the warranty from the settlement, I had to work with the dealership. I contacted the dealership again on 3/12/26 and they said they can't do a warranty replacement because the warranty only covered if it was the rod bearing.

While driving, my vehicle developed engine knocking, lost power, overheated, and produced smoke from the engine compartment. Shortly after, the engine seized and the vehicle will not start. An authorized dealership diagnosed the failure and recommended a complete engine (long-block) replacement, indicating catastrophic internal engine damage. This failure appears consistent with known Theta II engine bearing defects. The manufacturer is refusing coverage by stating the owner did not bring in the car for the recalls. The recall was preventive monitoring software (KSDS) and did not repair or prevent the underlying mechanical defect that caused the failure. This is a safety concern, as the failure caused loss of power and overheating, creating risk of fire or accident.

I am reporting a safety defect on my 2013 Kia Sorento (VIN: [XXX] ). Before the failure, the vehicle began experiencing sluggish starting, sputtering during acceleration, stalling when stopped at traffic lights or stop signs, a noticeable fuel odor, and eventually a check engine light. These symptoms increased over several days, and once the check engine light illuminated, we had the vehicle towed to a Kia dealership for diagnosis. At the dealership, the problem was confirmed and reproduced by their technicians. They diagnosed: •Fuel leakage from the high-pressure fuel pressure regulator •Fuel contamination in the engine oil These components and diagnostic findings are available for inspection upon request. This issue poses a significant safety risk. Fuel leakage and fuel-in-oil contamination increase the potential for an engine fire, and the hesitation, sputtering, and stalling at intersections present a risk of unexpected loss of power in traffic, which could result in a collision. The vehicle previously had its engine replaced under a Kia recall in 2020, and the current symptoms are consistent with known Kia engine and fuel system defects addressed in past recalls and technical service bulletins. The vehicle has been inspected only by the dealership so far; it has not yet been inspected by the manufacturer, police, or insurance representatives. Kia Consumer Affairs has been contacted and is reviewing the case. I am requesting that NHTSA review this issue as a potential defect trend involving the high-pressure fuel system on this model, especially in vehicles with prior recall-related engine replacements. Documentation from the dealership, including the diagnostic report and repair estimate, is available upon request.

My motor is knocking and losing compression

The contact owns a 2013 Kia Sorento. The contact stated that while stopped at a stop light, while depressing the accelerator pedal, the vehicle lost motive power in the intersection. No warning light was illuminated. An independent mechanic was contacted. The vehicle was towed by the warranty company to AAMCO, where it was diagnosed, and determined that the engine needed to be replaced. The contact was informed of an engine recall, and the vehicle was then towed to a local Kia dealer. The vehicle was not repaired. The manufacturer was notified of the failure, and informed the contact that the original owner would have received the recall and that the repair would not be covered. The contact was informed that the former owner should have notified her of the recall. The approximate failure mileage was 114,000.

In 2017, our 2013 Kia Sorento was brought in for recall work associated with SC147. The work was completed, and the Kia service department stated that even though we have a branded/salvage title, we would receive the extended warranty associated with SC147. Recently, while driving down a busy highway, the engine started knocking, at which point the check engine light came on, and the vehicle would no longer accelerate. The car had to be pulled off to the side of the road, and towed to a repair shop. Upon inspection, the repair shop indicated the issue was related to SC147, and would need to be taken to Kia for further inspection and repair. Kia has indicated, now, that SC147 was closed due to the inspection and KSDS update done in 2017, and that we are not covered by the extended warranty associated with SC147 due to the branded title, which contradicts what was previously stated by Kia's service department. Kia has stated that they will NOT replace the engine. Even though this is a safety issue associated with SC147, Kia is unwilling to take accountability and seems to be sidestepping replacement due to having a branded/salvage title.

I was on my way back from California to Mississippi when motor derated and started knocking in Williams , Az. My Kia only has 137,000 miles and Kia denying my claim for the extended warranty claim. I change my oil myself and keep my vehicle in great shape. To deny claim they also have to prove lack of servicing caused the defect. That is part of the Magnuson-Moss warranty act. I rented a vehicle to get back home and hired a trucking company to bring Kia back. They never did and after my job let me take two days to get my car back home I rented a truck and trailer to bring it home. So yes I’m very ill about Kia’s work practices.I took Kia to the dealership in Tupelo,Ms. and Kia had them remove valve cover and deny my claim. The vehicle messed up in July, but I wasn’t able to get it till September 1,2025 and then get it to dealership. It has been there till today cause I went and got it. I’m still waiting to get my denial letter.A woman by the name Vanessa is the one who called me to tell me it was denied. Mileage is a little over the 137,000. But battery is completely dead so I can’t get the exact mileage.

my vehicle falls under the 2013 Kia Sorrento engine replacement and fuel pump. Recall these have not been done to my vehicle. I even double checked with the previous owner and Kia did not service the engine or replace it although it has a recall under mine, and all the symptoms stated in the recall with the engine and fuel pump are happening with my vehicle now how do I get this service covered under the recall also a very strong fuel odor

While driving down the road the car just went dead. No warning. It was the oil pump that had gone out and froze the engine causing complete loss of control of the vehicle.

premature bearing wear within the engine

While driving the car will stall, making maneuvering the car to safety difficult. There was no warning that this was happening. I did take the car to a mechanic, he said because the engine light was not on, he could not track the problem. I had this happen at least 6 times in the past few months

Engine failed to start and made loud knocking noises. Knocking noises continued and vehicle towed to dealer. Oil level was full and all routine maintenance performed up to this point. Oil level full at time of failure. Dealer confirmed knocking, stated the knocking went away after running for a period of time. Dealer requested 3 hours of labor and we are currently determining our next step. The vehicle is available for inspection at Kings Kia in Northern Cincinnati. 137,000 miles. Also have video of engine knock. Recently had HECU recall and it potentially caused ABS light, independent repair shop recommended new HECU after recall performed due to low voltage from yellow wire, dealer claimed replacing wheel speed sensor, we still suspected other electrical issues may have been caused.

The car just completely stalled while driving on a busy street with myself and my children in the car. I first was alerted that it may just be the starter by a local mechanic. I fixed that and it still would not start. I then went and got a new battery and that did not work either. At that point I had the car towed to the Kia dealership. The mechanic told me that the car engine was a part of a recall for Kia. He told me that he would put the claim in and that Kia would fix it. He told me to send in my registration and drivers license. A couple of weeks later he informed me that they would not fix my engine because the registration was expired. The expired registration has nothing to do with their faulty recalled engine. I had this issue escalated and still was told they would not fix it.

When we bought this car several years ago after a test drive, we left the lot and about 5 or 6 miles down the road it completely shut down. The dealership ( Smail Auto) fixed the engine so we thought. We were told not to mention anything about the engine problem to anyone or we would lose the car. We get it back and again does the same thing. Ever since that day our car has been down more than driven. We attempted to contact the dealership and nobody would reach back out to us. All the lights on the bashboard check tire, engine, gas light, etc are all on everytime this happen. Even now we attempted to get ahold of the dealership or even Kia and nobody has called me or my wife. The break downs happen on different dates. But the latest on happen 5/30/24
