On Sunday 2-4-2024, at ~2-3am, my daughter & her boyfriend were driving her 2015 Kia Sorento on I69 near Fishers IN (67 miles from their home) when the engine rod bearings failed. Driving at interstate speeds, they immediately pulled over to the shoulder. If traffic had been bad, this could have caused a deadly accident. This created an emergency roadside service issue. Fortunately, my daughter's boyfriend was with her to help her through this anxious & traumatic event. It took a couple hours (in freezing cold weather) for them to figure out what to do. They called us (her parents) at 5am for assistance. They eventually got a tow truck to tow the car back to our hometown's Kia dealer for service. On the next business day, the Kia Dealer diagnosed the problem as a blown rod bearing; the engine was locked up. Cost to repair will be ~$5900 plus a $589 towing charge. Quotes are included with this complaint. After some research, I discovered that faulty rod bearings is a HUGE problem on mid-2010's Sorento 2.4L engines. The internet is full of customer complaints on this. In addition, there is even a Theta II Class Action Lawsuit on this. The problem is THAT pervasive. I have contacted Kia Customer Service (Irvine, CA) and the Kia Theta II Customer Service group. They explained that because they obliged by conditions of the Theta II lawsuit, which, for them was two mailings to DMV registered owners in summer 2018 & summer 2019 requesting owners to install an ECU software upgrade (followed by a 3rd mailing by the lawsuit handling firm: Epiq), that their liability on this matter is covered. The previous owner did not open or see these letters. So this upgrade was not done on this car. To me, Kia/Hyundai acted in BAD FAITH not to continue with mailings (once every 6 months) to all DMV registered owners UNTIL all registered cars had dwindled to very low numbers (<10% of initial sales). Therefore, I think they are STILL liable for this safety & traumatic issue.

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.

Check engine light started coming on at about 39,000. miles took to local mechanic who preformed lots of repairs and called Kia for information concerning engine issue. Received notice of recall from Kia on the HECU -instructing me to park truck away from home due to fire. Check engine light back on again at 41,000 miles, took to dealership where they replaced the HECU and fuel pump and fuel lines. Picked up truck and noticed when braking the truck shook all over and seem to almost stall when taking off. Check engine was back on and the alert of the system telling me I had an engine failure. Took truck back next day, again repairs of the PVB valve was done. Someone drove the truck of 180 miles on a check engine light and unplugged the battery. Got truck back and within 10 minutes the check engine light was back on and the system telling me engine failure and truck was unsafe to drive. Truck now at another Kia dealership, after many conversation with Kia the representative instructed me to tell the dealership where the truck was that the truck had a recall (supposedly) fixed. Called the dealership now tells me there is no fix for the HECU issue and they can not tell me the truck is safe to drive. I have not had the truck for now 4 months and Kia doesn't know how to fix it. I have filed 4 cases against Kia, they have not offered me a rental car or loaner and they do not have any expected date for me to get the truck back. I have files but it won't let me upload them for the receipts/ information from Kia

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 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.

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.
