2021 KIA SPORTAGE Complaints

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.

The infotainment center screen in my 2021 Kia Sportage is DELAMINATING. The uv gel adhesive that holds the screen is failing. This is a known widespread safety issue as many controls are handled through the infotainment touch screen as well as the screen displaying the back up camera visability. You should force Kia to fix this problem past 3 years /36000 miles! Please advise me.

The contact owns a 2021 Kia Sportage. The contact stated that while parked on several occasions, a "Battery Discharge Warning" message was displayed, which disappeared once the vehicle was driven. The contact then stated that on several occasions after the vehicle sat unoperated for a day, the engine failed to start. The contact's husband jump-started the vehicle on multiple occasions and noticed that the battery was completely drained. The contact's husband replaced the battery approximately three times; however, the failure persisted. The vehicle was taken to an independent mechanic, where it was diagnosed with an electrical issue, requiring repair or replacement. The contact was advised to take the vehicle to a dealer for a full diagnosis. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

While driving southbound on Route 93 on 6/11/2026 during the morning commute, my 2021 Kia Sportage suddenly sputtered and lost the ability to accelerate. I was traveling about 65 mph in heavy traffic when the vehicle abruptly lost power without any warning lights or prior symptoms. As my speed dropped, I had to cross multiple lanes to reach the breakdown lane, creating a dangerous situation for me and surrounding drivers. The vehicle had to be towed to a repair shop, where I was informed that the high-pressure fuel pump had failed and needed to be replaced. The car has only 22,000 miles on it and is just one month out of warranty. This sudden loss of drive power at highway speed poses a significant safety risk.

While I was driving in the interstate my car when in limp mode while I was trying to pass a semi. I had my children in the car and was stranded on the side of the road. No warning lights ever came on before hand. My mechanic said it was a problem with my engine and it’s common in Kia’s in but doe not include my year. It’s a costly repair for a car that’s not even 5 years old.

Loosing oil constantly. Always on the low end. I am having to keep oil in my car to put in it when needed which is often.

The engine in my 2021 Kia Sportage failed while being driven at highway speeds on US 131 in Michigan. The car was taken to the closest gas station where the oil was checked and it was determined that 5 quarts were needed to reach the dipstick's full line. The fact that the car had consumed 5 quarts of oil seems to be a major safety concern. I've attached a note with additional information that has also been submitted to Kia; a case number has been provided. However, after several weeks, there hasn't been any progress. I haven't even been able to get Kia to provide information as to the fundamental root cause of the engine failure.

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
