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.

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 mother owns a 2015 Kia Sorento. The contact stated that the vehicle was experiencing an abnormal oil consumption. The contact stated that the vehicle consumed three quarts of oil after driving 367 miles. There was no warning light illuminated. The vehicle was taken to an independent mechanic, who informed the contact that the vehicle could be experiencing an internal oil leak. The vehicle was then taken to the dealer, where an oil consumption test was performed. The dealer informed the contact to come back after 300 miles. Additionally, the contact stated that the air bag warning light was illuminated, and the front passenger's side seat belt pretensioner failed to operate as intended. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 96,000.

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.

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.

- Philadelphia, PA, USA

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.

- Littleton, CO, USA

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.

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

- Chicopee, MA, USA

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.

- Lakeland, FL, USA

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.

August 11,2023 My 2015 Kia Sorento engine light came on, it started bogging down, and rattling noise came from the engine, when plugged in it was diagnosed as the exhaust crank shaft position timing-over-advanced (Bank 1) Code P0014. I had a hard time keeping the engine running it kept wanting to stall out while driving down the road to safely make it home. I'm lucky to have made it home and not stranded out on the highway. I'm told know the engine has failed. I will need rods replaced; I've had all my recalls done but yet this still has happened to me. I thought 1 of the recalls was for this very reason yet it still happened, how is this possible. As I've read through other people's issues, I'm also at 85,000 miles and had no warning that my engine would be shot. If you have a Kia 2015 Sorento sell it or trade it in now, especially if your mileage is hitting 80,000 mileages.
