2015 Kia Sportage: engine knocking or ticking

Filed Apr 23, 2026 · Engine, Transmission · NC

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 federal safety agency investigate this practice, as it prevents consumers from accessing the safety-related warranty protections they are entitled to." Tips for your submission:

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.

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.

Two weeks ago my car began making a loud knocking noise from the bottom end and emitting a burning smell from the engine out of nowhere, without any warning lamps. I took it to a mechanic I trust. As soon as he heard the noise and looked at it he told me it was bad and that I could not drive my car, it concerned a HECU unit and/or fuse and could potentially lock up or start on fire. He gave me a printout with the federal safety agency Recall# 22V051 on it and told me I would need a new engine. When I called Kia Customer Care they did not have the recall number. I gave it to them and they put me on hold for 45 minutes so they could do some research; the representative and her supervisor eventually found the recall and authorized a safety tow to Peak Kia in Denver, CO At Peak Kia they told me they looked at my car and it would need a new engine, but there was nothing they could do because my car was past warranty. That was the first time I had ever heard of anything about a warranty or it being past due. The service clerk told me it would be an out of pocket expense of 6 -12,000$ for a new engine and explained that this was because my car had gone past 100,000 miles, and the engine had already failed so the warranty could not be extended. She also told me to contact my dealership because they could be at fault. I left that building scared, because I still owe about 8000$ on my loan. I purchased the vehicle in Rapid City, SD with my parents at a non Kia dealership called Granite Nissan. When we called the dealership they said they had not been informed of a recall by the previous owner or Kia manufacturers. Neither had I at the time of purchase, or since. My dad and I checked Kelley Blue Book to make sure. I was then informed that the dealership does not have legal responsibility to alert buyers of this info. Now we are being repeatedly told that this will be my expense, and it is a scam. Kia made a car that promised reliability and safety, but have left the defects up to the owner.

I was passing a vehicle on a 2 lane (one lane going in each direction) highway at approximately 55mph when my car engine lost power. I had to immediately get over and pull to the side of the road towing vehicle to Webster Tire and Auto in Teutopolis, IL. They originally thought it was the alternator but they said engine was knocking and needed to be replaced. I found out that there was a lawsuit for this issue and that Kia has a service campaign. Although I had searched the NTHSA website and Carfax, because I purchased the vehicle recently the only way for me to have expected the issue was for me to have contacted Kia directly or to be notified by the person who sold me the car. I was also denied a claim on this lawsuit because I had not had the service update which would have extended the warranty on the engine and fixed the knock sensor issue. This information should be readily available to consumers and owners. I had this vehicle at Walmart for an oil change and Webster tire and auto for other maintenance prior to incident and neither of those companies were aware of this service campaign.
