Chronological view of owner reports
Car shut down driving down the road and spun a bearing.
Manufacturer failed to honor repair of seriously damaged engine due to a faulty distribution in oil causing a major engine failure. KIA USA Manufacturer is currently under massive lawsuits due to this issue and which involved the model we purchased. Vehicle has very low mileage of 85085 and should be covered under the manufacturer's warranty of 100,000 miles. Manufacturer claims they declined our claim because we failed to attend to a massive genetic form mailed to all owners in 2018. As a consumer we are simply asking they honor the warranty and replace and/or fully repair the damaged engine in our family SUV.
Car suddenly had a knocking sound, check engine light came on and as I was driving, the car loss power suddenly died and woudn't start back up. Mechanic diagnosed that head bolts came loose and damaged engine. Has been at mechanic since 11/27 with the engine being rebuilt. Aprox cost at $7,600.
The contact owns a 2015 Kia Sorento. The contact stated that while driving at approximately 50-55 MPH, he heard an abnormal popping sound and the vehicle spontaneously caught on fire. The contact was able to pull off the highway. The contact stated that he could see flames under the hood. The contact called 9-1-1 however, by the time the Emergency Services arrived on the scene, the fire was independently extinguished. The contact stated that the fire started in the engine compartment. The engine was previously replaced at 85,000 miles. The check engine warning light was occasionally illuminated and then disappeared on the vehicle. A Police report was filed. The Fire Department also arrived on the scene. There were no reported injuries. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 155,565.
The car has 106,000 miles, engine suddenly have knocking sound when started the engine then it will go away with no indicator of any issues. A week later, my wife was driving it and the knocking sound turns very loud and the car went into the limp mode and almost cause her to get into a car accident. We took the car to the Kia dealership and it was determined that the engine has a lower end rod knock due to bearing failure, the long block engine assembly needs to be replaced. I researched it and this is a commonly known issue for Kia's engine that already affected many other Kia owners.
Car temp gauge would go up high and go back down. No check engine light when this would happen. Took to mechanic and found out the radiator and the engine head gasket needed to be replaced.
While on the freeway, the engine started making a loud knocking sound and the car was losing power. No check engine light or other warning lights were illuminated. I exited, parked and later towed the car back to the Kia dealership and they said I needed a block (engine) replacement at a cost of over $10,000. I have performed all routine maintenance on this car at the dealership, so this is unacceptable. Luckily I was able to exit the freeway and was not in an accident because of this failure. My car had approximately 109,000 miles on it.
On June 20, 2022 my KIA Sorento with 137,170 miles stopped suddenly in traffic on the interstate during morning rushhour. I had no engine light warning. The vehicle would not restart. I inspected under and behind the vehicle for any issues and found none. I motor was locked up and upon checking the oil, the stick was dry. I had the vehicle towed to the KIA dealership that has serviced the vehicle since it was purchased. I was present when they put the vehicle on the lift and found no fluids on the underbody. I had them drain any remaining oil. 1.5 qts were left. Upon additional inspection the passenger side of the engine had some oil residue near the pressure sensor. The vehicle was due for an oil change within 2k miles. One month prior I checked the oil and the level was fine. The vehicle had never used oil before. Dealership wanted to charge $12k for a motor that had 165,000 miles on it. I was able to replace motor with another that had 64K miles for $8,500 at my personal mechanic. I've notified KIA numerous times and they deny any issues with the motor. I received a letter from KIA six months prior to the motor locking explaining there might be an issue with the Oil Pressure switch and sudden loss of oil, It stated they would cover any chages. I'm still fighting with KIA. I've owned five KIA's, this is my last one.
Without vehicle warning lights, I was driving on a highway and my engine began making loud noises. My safety was put at risk as my car did not indicate any warning there were any vehicle issues and I was on a major highway which could have potentially not only affected my safety but the safety of others.
Engine failed and started knocking on 8/29/2023. Had it towed to dealership where it has been sitting ever since. I am being told that its taking 8+ weeks to get approval on a new engine from KIA due to the defects of their engines. They will not supply a loaner or rental car until (IF) the engine replacement is approved.

Without warning, engine stalled while in motion. Electrical system was still functioning and on. Loss of power steering and power brakes. This continued to happen at random times during driving, putting all passengers at risk. Kia dealership looked in to the problem and diagnosed it as a faulty PCM/ECM module and replaced. Rolling engine stall continued and continues to happen at intermittent times. We are now 6 months in to the process of trying to determine the issue. The car has been taken back to Kia dealership for inspection. The problem has been reproduced by another auto repair shop but they are unwilling to work on it since there is no check engine light or corresponding code to work from.
Unknow
It is abusive to American consumers that Kia Motors America knowingly sold several Kia models from 2011-2019 with the Theta ii engine issues. They have not done enough as a car company to support the needs of customers that are affected by this problem. They are taking 2-3 months to diagnose and repair failed engines at dealerships. Additionally, they are not doing enough to help people when they don't have access to their car. I was forced for 2.5 months to have no car without a loaner vehicle offered to me. I experienced a Kia Sorento 2015 engine failure on 6/1/2023 and was not fully repaired until 8/18/2023. During that entire timeframe, I had to file a BBB report at 60 days to get an update on the diagnosis for my car. When I went to pick up my car on 8/19/2023 at Cochran Robinson Kia, they lost the key to my car and acted like it was no big deal. I am sick and tired of Kia Motors America being allowed to continue selling faulty vehicles in our country. They need to be shut down and charged to the full extent of the law as a car company.
Engine blew
The engine of this vehicle has always rattled on start-up, but the sound goes away after a few seconds. Oil levels have always been maintained and the oil has been changed on a regular basis at the scheduled mileage intervals. Within the last month, the engine rattle is present when shifting from 2nd to 3rd gear, at approximately 30-40 mph. The engine rattle is coupled with a revving sound that would indicate that the engine is working hard to accelerate, yet the RPMs remain relatively low for the amount of sound made by the engine. To date this has not posed a safety risk, but I consider it to a potential safety issue if the engine failure problems present in other Kias of similar years are also present in this year and generation of Sorentos with V6 engines such as this vehicle. The engine issue is currently being inspected by a mechanic to see if they can replicate the issue and identify a specific problem. No inspections have been performed to date by the manufacturer, police, or insurance representatives. No engine lights or warning signs were present before this started occurring.
The engine was inspected for a possible timing chain rattle/issue and was found to be consuming oil. The oil level was low with no obvious leaks from the engine, meaning that the engine has been burning oil for about 4 months since the last oil change at the very least. The oil consumption could cause engine to wear and fail during operation, causing obvious safety issues for this model, as is the case for other Kia models affected by a class action settlement. The issue has been confirmed by an independent mechanic, but has not been inspected by the manufacturer, police, insurance representatives or other individuals. There were no warnings of low oil levels prior to being informed of this oil consumption issue.
Going on vacation with elderly disabled mother and family. Exited off highway stopped and car just shut off with lots of traffic behind me and coming. After several attempts to start vehicle it started and was really loud. Pulled out and coasted to a place I could safely pull over. Checked the oil, belts, and for leaks and no check engine light or other warnings. With no other real options, I drove with flashers on and coasted to our hotel with minimal power and the engine compartment sounding like it was coming apart. Grinding popping and knocking. Still no check engine light. Once stopped at the hotel, the car cut off in the parking lot and had a weird fumes/burning smell. With it being a holiday I had to find a shop and wait until they were back open to see if they would take my car. There were no KIA dealerships in my area. I called and had the vehicle towed to the shop. They say it needs a new engine. The car is still out of state which is going to cost hundreds just to get the car back home and not to mention the 8000-10000 in engine repair. Also we were lucky it didn't catch fire with the fumes/burning smell or be involved in a wreck due to the car just shutting off with no warnings at all.
Engine failure , car stopped running , me and my family could’ve gotten a very bad accident , I had to pay 8,400$ out of my own pocket to replace the engine failure
RE: Kia Engine Failure I have a 2015 Kia Sorento that has approximately 86,600 miles. My engine failed on July 5, 2023. I did receive the Recall No. 18V907000 and tried to contact Kia numerous times when I received the notice to get my software updated; however, I was unable to speak with anybody from the service department and had left numerous messages to no avail. Shortly after the recall, I had a heart attack and needed time to recuperate. Then Covid hit, my doctor advised me to quit my part-time job and stay quarantined due to my high risk of contacting Covid due to being a diabetic, having a recent heart attack and other medical ailments. I have been disabled for 12 years and have other medical issues that I'm dealing with. Recently on July 4, 2023, when I was driving my car, my engine started making a knocking sound. It made a loud noise and felt like it was stuck in gear. I took it into my mechanic the next day who confirmed that my engine was going out. The check engine light never went on. The next day when I drove it to the market, the car completely went out. I have been trying to get in touch with Car Pros Kia in Huntington Beach, CA. and Kia of Irvine, as well as contacting a lot of phone numbers regarding the Kia lawsuit, but nobody answers the calls or returns your messages. You can be on hold for hours. I had an appointment this morning to get recall updates on my car, which I scheduled several weeks ago before my engine failure. I called the service department of Kia of Irvine in CA., and explained to the service advisor, Cody Brown about my engine failure if I should take in my car for the scheduled recall updates. He advised me not to take it in, because in order to complete the recalls, the engine needs to be in working condition. I inquired about my engine failure to see if it was covered under the lawsuit. He advised me that it was not and that I had to contact the Kia manufacturer, which I did, but have been on hold for hours.
My engine went into limp mode on the road wile my daughter was in traffic. After she was finally able to get the car to the side of the road. I had the Sorrento towed to my local mechanic. The mechanic informed me the engine had an internal engine failure.The car had 125,000 miles I have always done my oil changes at 5000 miles with synthetic oil. Spoke with Kia they said I would have to a Kia Dealership mechanic diagnostic. The Kia dealership said the engine had an internal engine failure. They said it is some type internal failure but have not said what is failed.
The car completely stalled out. Engine Light on.
After hearing a knocking or rubbing sound when turning left or right, I made an appointment to have my 2015 Kia Sorento checked and also to have it inspected. The auto repair shop was in the middle of road-testing the vehicle when it suddenly began running poorly and the SES light turned on. The vehicle started to misfire and was unable to accelerate past 30 - 35 MPH. Upon inspection the car was found to be very low on oil, although there had been no prior alert nor was it time for the routine oil change. Vehicle also shut down unexpectedly on road, putting driver and other vehicles in danger.
Sudden engine failure. Upon inspecting the vehicle Kia mechanic concluded engine failure is due to rod bearing wear, which isn't part of the engine failure recall. Thus customer is responsible for all expense in full.
The contact's stepson owns a 2012 Kia Optima. The contact stated that while his stepson was driving at an undisclosed speed, the engine seized. There was no warning light illuminated. The driver was able to veer to the side of the road. The vehicle was towed to the dealer, where it was diagnosed that the engine needed to be replaced. The contact related the failure to an unknown recall. The dealer informed the contact that the vehicle could not be repaired free of charge because the vehicle was not covered under warranty nor recall. The dealer referred the contact to the manufacturer for assistance. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 111,000. The VIN was unavailable.
