Check engine light by model year
What owners say
On June 14, 2026, the driver experienced sudden rough engine running followed immediately by a flashing check engine light. The vehicle was towed to the selling dealer, which has performed all prior maintenance. The vehicle is currently at the dealership and available for inspection. Technician notes show DTC P1326 was stored — the Knock Sensor Detection System code associated with connecting rod bearing wear on Kia's Theta II engine family. The technician performed an audible knock check only (none heard) and cleared the code. The vehicle was found approximately 2.5 quarts low on oil due to an internal turbo oil leak. The dealer's notes state the code "may be related" to low oil — hedged language, not confirmed causation. The dealer confirmed the turbo failure but has not performed a bearing clearance test to confirm or rule out bearing damage from the low oil condition. The dealer performed a turbocharger replacement. Despite a verbal commitment from the service manager that a bearing clearance test would follow, no such test was performed 40 days later. When the vehicle was declared ready, the service manager did not recall the commitment and suggested driving 40-50 miles as an alternative. Kia America opened a formal case last month and authorized a partial goodwill adjustment but no one has addressed the safety concern of the unperformed engine test indicated by the thrown code. Driving a vehicle with potential connecting rod bearing wear risks catastrophic engine failure, creating a serious safety hazard. This vehicle has a documented history of oil consumption prior to this incident. The engine has not been cleared for bearing damage following a significant low oil event and a stored P1326 code.
On March 4, 2026, the engine in my 2021 Kia Sportage malfunctioned while I was driving on a local road on Long Island, NY. The check engine light illuminated, the vehicle lost the ability to accelerate normally, and the steering wheel became heavy and difficult to turn at the same time. This created a serious safety risk, as I was unable to maneuver or accelerate normally and could have been stranded in an active roadway or unable to avoid a collision. The vehicle was able to restart but was towed as a precaution and transported to service. An independent repair shop examined the vehicle and identified the issue as an engine problem, advising that the repair should be covered by Kia. I delivered the vehicle to Kia Smithtown, an authorized Kia dealership, on March 9, 2026. As of today, the dealership has had the vehicle for approximately six weeks and has not yet completed a formal diagnosis or begun the repair, and no loaner vehicle has been provided. No police or insurance inspection has occurred. The check engine light first appeared at the moment of the failure on March 4, 2026; there were no clear warning symptoms prior to that. The vehicle remains in the possession of Kia Smithtown and is available for inspection.
I was driving only going around 35 miles and the car went from no check engine light to flashing check engine light I had it taken to a show and was told the rod bears where grinding away and putting metal in the oil which is what the 2017-2019 model of the engines had the same problem

I had catastrophic engine failure driving down the road to work. Check engine light started flashing the the oil light. The car then shut off. Got it towed and they found two pieces of the engine block in the cradle cover.
Kia Sportage 2021- The service department at the dealership ran basic inspection of fault codes and found fault in system for knock sensor and camshaft b position sensor. These codes have relation to engine failure or possible timing chain failure. My safety was put at risk as I was driving down the highway and my car would not go over 40 miles per hour and cars were serving from hitting me from behind. Then my check engine light came on and started flashing. This information on my vehicle was looked at the dealership I purchased my vehicle, and they do not have the software/special tools to repair/replace timing components and vehicle was towed to Kia dealership. There was no warning lamps or symptoms that warned me before it happened. Once it wouldn’t go over 40 mph (wouldn’t accelerate) and my car light came on and blinking I pulled over.
