The whole engine needs replaced without warning. I have been driving it with oil spraying, a hole in engine and not sound or engine light or anything as a warning. Very unsafe and many others in the same boat.
The contact owns a 2018 Kia Sorento. The contact stated while driving 50 MPH, the vehicle lost automotive power and jerked and decelerated to 25 MPH. The contact stated that several unknown warning lights were illuminated. The vehicle was driven to a nearby parking lot and parked because the contact was concerned about driving the vehicle. The following day the contact’s husband took the vehicle to a local dealer; however, the vehicle was not diagnosed.

The engine seized as we were driving onto the freeway. Everything just stopped. The car had to be pushed to the side of the road. It failed to restart. When we checked the dipstick, it was completely dry and starting to burn on the bottom. There was no visible signs of an oil leak. There were no lights or other notifications that the car was out of oil. We were lucky the car wasn't hit and someone seriously injured or killed. The car had to be towed to our home. Kia Corporate Office was closed. The Kia dealership said I could have it towed at my expense and have it looked at when they had time the following week. It was just under 100K miles A different Kia dealership offered to give me $5000 towards a trade-in on a new car. That was half the trade-in value, but I couldn't be without a car. When I inquired three weeks later about what the service department found out was wrong with the car, I was told they hadn't even looked at it and would probably just use it for spare parts.
Engine had catastrophic failure without warning. No warning lights or performance issues. 110K miles on it. Well taken care of and taken in for oil changes at regular intervals 6K-8K.
Around 90,000 miles, the engine started leaking oil regularly, took it in for warranty. After repairs for gasket, then started burning oil and running of oil every week or two weeks, and I have to constantly refill oil. Took it again and Dealer told me I am out of warranty, then I called KIA USA and reported problems. They told me that they will get back to me and I am still waiting.
Previous Complaint# 11618337. Additional Information: Engine is full of oil yet Oil Light comes on due excessive crankshaft & connecting rod bearing wear and knocking loud. Yet the recalibrated knock sensor will not pick up the issue and put the vehicle into derate with a code P1326 as it did before the Kia Dealership performed this recalibration. This is consumer fraud by purposely hiding a known defect and preventing the warranty from replacing the engine with a redesigned new engine that corrects the issue with larger oil ports. It is also a safety issue!! Now that the oil light is coming on and the engine has a bad knock, it can fail at anytime while driving causing lose of power steering, brakes and the ability to safely pull the car over to a safe location. The original P1326 code automatically determined the engine developed wear from lack of oil volume based on the known defect of too small oil ports. This recalibration doesn't address the wear the engine already has and based on what the dealer stated, they will not replace the engine until that code comes back. Which now can't happen due to this parameter change and elimination of the knock sensors ability to perform it's job correctly. Please investigate and resolve, Thank you!!
Engine is burning oil. Engine only has 116,000 miles on all maintenance has been kept up to date - has never missed an oil change, only ever used full-synthetic. Should not be consuming this amount of oil. Also dash board lights pertaining to engine or oil never come on.
Car is burning 3/4 a quart of every 1,000 miles

The vehicle was pulled to the side of the road and inspected. The contact observed condensation under the front of the vehicle and no oil on the dipstick. Additionally, another vehicle pulled to the side of the road and reported that condensation from the vehicle sprayed onto the windshield and hood of their vehicle.

Engine was consuming large amounts of oil, attempted to conduct oil consumtion test per Kia request was unable to complete due to volume of oil consumption . Engine locked up after kia telling me they couldnt help me since the oil consumtion test couldnt be completed.
The vehicle started knocking. We took it to Kia and they share saying we needed an upgrade part that is on a safety”notice” and not a recall. It’s to prevent engine failure. They refuse to put in the part because they said the engine is already failing. They said we need to pay 6k. The best part is that we took the vehicle in last year (2023) for the hitch and the anti theft upgrade and KIA didn’t tell us about this feel part. Why wouldn’t we get the free upgrade on the engine???? They are not telling consumers and it doesn’t come up when you search by VIN.
On May 1, 2024, I noticed my 2018 Kia Sorento making a knocking sound and smoking heavily from the back exhaust. I turned it off, thinking it might be overheating, and planned to check it the next day. On May 2, 2024, while taking my daughter to school, the vehicle was knocking but no indicator lights were displayed, the main display screen suddenly showed an engine control system issue, and the car spoke and said to take the vehicle to the closest service center I immediately headed to the Kia service center. About 2-3 miles into the drive, the car shut down completely on the interstate. I managed to coast to a stop on the access road but was still partially on the road, so I called for a tow. The police later helped me move the car further off the road because I was a hazard for Morning rush hour traffic. After waiting for three hours, the tow truck took me to the Kia dealership, where the mechanic found that the engine had seized. Kia refused to repair the damage, citing that I hadn't done a KSDS recall. The repairs are estimated to cost over $7000 needing long block replacement from hole in block (KSDS requirements not met). I was not aware of any issues with my car, as I had not been informed about a KSDS recall or any suggestions regarding it. I feel this situation put me in danger, first with the potential fire hazard and then being stranded on the highway and nearly struck in multiple occasions. . I currently have no working vehicle, and Kia is not taking responsibility for these engine issues but my make and model has no listed recall. I am not considered a part of the KSDS recall therefore I also get no claims to the millions awarded to others due to this recall.

While driving my 2018 Kia Sorento on Interstate 95 at approximately 65 mph, the vehicle suddenly started to knock. The noise got louder and before I could safely pull onto the shoulder, the engine totally failed without any warning lights whatsoever. Large amount of blue smoke came from the exhaust and I lost all power to the vehicle. Engine parts and motor oil were scattered all over the highway from the violent nature of the failure. This also caused vehicles behind me to swerve and brake in order to avoid hitting the metal engine debris. My right rear tire ran over such metal and it immediately went flat. I was able to coast the vehicle onto an exit ramp where I raised the hood to check for fire. The engine continued to leak oil while parked on the off ramp shoulder. I called my insurance company to let them know what had happened and a tow truck responded approximately 1 hour later and the vehicle was placed in an auto storage lot.

The car stalls any where when the temp is over 108 degrees, i have to wait about two minutes and it will start, sometimes it cranks then it starts, no codes come on the code reader. It has never happen since i bought the car 5 years ago. The car is not over heating, it stays on the same temp and no antifreeze comes out.
Ive been experiencing engine failure with my vehicle since December of 2022. The car was assessed and repaired and less than a month later my engine has failed yet again while driving. My vehicle year is not listed in the kia settlement class action even though I have a Theta II engine 2.4 L GDI.
My car is using more oil then it should and I’m getting bad gas mileage. I have no leak you can’t smell anything and it doesn’t run hot! But we have to add a least 2 quarts a week.
Vehicle is consuming oil at an extraordinary rate. About 1qt per 750 miles. There are no oil leaks present.
My car is using 5 quarts per oil every 250-500 miles. Which means my car can blow up with me in it. I took it to the dealer and even though there is a tsb on this and it is a known issue they are telling me kia will not cover it I have to replace it out of my own pocket. When this occurs no oil lights or engine lights come on.
