Unjustified Denial of Engine Warranty Coverage - 2015 Kia Sportage "I am filing this complaint because Kia is denying warranty coverage for a known engine defect (rod bearing failure in the Theta II GDI engine) on my 2015 Kia Sportage. The manufacturer’s denial is based on the claim that I did not perform the KSDS (Knock Sensor Detection System) software update in previous years. However, I have officially performed this update at an authorized Kia dealership (Hendrick Kia of Cary) on April 17, 2026. Despite my vehicle now fully complying with the recall requirements, Kia continues to deny the warranty claim by retroactively applying a 'missed update' penalty. This is a clear attempt to evade their obligations under the class-action settlement regarding this engine defect. The manufacturer is holding the current owner responsible for maintenance history they cannot control, even though the vehicle is now technically compliant. I request that the NHTSA investigate this practice, as it prevents consumers from accessing the safety-related warranty protections they are entitled to." Tips for your submission:

I own a 2015 Kia Sportage with an open safety recall (NHTSA Recall No. 22V051 / SC227B). The vehicle became undriveable years ago due to engine issues. I contacted both the dealership and Kia several times, but no one has responded or completed the recall. I received no notification letter. The vehicle has sat inoperable for years, and I had to stop payments because the engine failed and posed a safety risk. I am requesting NHTSA intervention as Kia has failed to complete the safety recall in a timely manner.

We were driving down the highway and without any kind of warning the car lost all power I had to move to the shoulder of the road and wait over 5 hrs for a tow truck and then get a hotel room for the night before we could get a rental car the next morning once they opened. Then, a couple weeks later we had to have the vehicle towed back home to NY since we broke down on [XXX] in PA. Then we had to have it towed to a repair shop and they told me it was rod iron knocking and was covered under the Theta II class action lawsuit according to the website when the vin# was inputted to the website. And Kia is saying it's not covered because of a recall that wasn't completed but being I never received the notification as I wasn't the 1st or 2nd owner of the vehicle.

I purchased the vehicle in February 9, 2024. A week after I purchased it the engine started making a knocking noise. I took the Sportage to Kia of Orange Park as I saw some there were some recalls on the vehicle. I paid to have a full diagnostic done. The gentleman that assisted me reached out to the Kia Corporation to see if they would repair the engine. Kia refused stating that the recall PI1802A - PI1802 (ECU Logic Upgrade KSDA 14- 15 MY) had not been done. This recall was out on the car prior to my ownership so there is no way for me to have it done when it came out.

I took the vehicle in to Kia due to excessive oil consumption. I was told they could not do anything and that I should continue to drive the vehicle. Kia stated that since I am the second owner (purchased at 7,800 miles) that I am not eligible for the original warranty. They stated that if anything were to happen to my engine I would need to provide documentation of oil changes from the first date the vehicle was purchased (which I don't have access to since I am not the original owner) and that Kia would assess to see if I were eligible for a new engine. They completed an oil change checked for leaks and sent me on my way. I continued to add oil every 500-1000 miles. On 4/11/24 I was driving me vehicle on the freeway at approximately 75-80 miles per hour when the vehicle lost power and would not drive over 40 miles per hour. Upon exiting the freeway the vehicle died at a red light. A tow truck driver took me to a mechanic who ran diagnostics and found codes P0300, P0302, and P0304. He stated that the 2 and 4 cylinders had no compression. Awaiting Kia inspection.

The engine began knocking on a crowded roadway. The Kia dealership noted an engine recall, but that engine replacement claim was denied because a KSDS sensor update was not completed prior because the corporate office did not have my updated address, and I never got the recall letter.

Had to stay in slow lane to get off and get back on to make it home. I was unsure as to what was happening.It was the weekend so had to wait until Monday until i could find out and the dealership told me it was the valve cover gasket (which is brand new).

My youngest son was driving on the highway at 65 mpg when all of a sudden, the car would not accelerate. We lost the ability to keep up the speed. The car literally just would not go. I was in the car and was able to put the hazards on in time to not get hit by the 4 cars behind us! We pulled over barely making it to the next exit. Had to call a tow truck that took the car to our mechanic. The next day I was told the engine was shot because an oil issue. This was something the dealership that I took the car to before for excessive oil consumption issues had told me was inherent to this kia model. Seriously!!!! Kia knew about this issue! I was told by the dealer to keep a very close eye on oil levels, changes etc. Which I did and this happens! Shame on Kia for allowing something like this to happen and not take care of. This is a safety issue! What if I wasn't in the car with my son? What if my teen driver got rearended by someone clearly not seeing he had car issues?? NO lights, No warnings! Just like when the oil issue first came up... the oil light didn't even come on! I cannot provide the mechanic paperwork at this time as I am at work, however I would be happy to if this reaches someone who really cares about safety! I have all the work records performed on the car since I purchased it. How can a company continue to produce and sell cars if they consistently and knowingly have safety issues! Or does it take someone getting killed and the news to report it to have something done?
