What 46 owners told NHTSA about the 2021 Kia Sportage Phev Phev

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 am filing a complaint regarding a 2021 Kia Sportage that experienced catastrophic engine failure, leaving the vehicle non-drivable despite regular maintenance and documented oil changes. I brought the vehicle to an authorized Kia dealership, located at 402 NJ-35, Keyport, NJ 07735, for evaluation. On or about March 17, 2026, I was informed by the dealership that coverage for engine replacement had been denied. At that time, I was not provided with a clear or sufficient explanation for the denial. Due to the lack of explanation and assistance, I escalated the matter to Kia corporate and was assigned a case manager. On March 30, 2026, I was contacted by my assigned case worker from Kia corporate, Marcia, who confirmed that my request for engine replacement remained denied. Again, no specific or sufficient explanation for the denial was provided, despite my attempts to obtain clarification. I made multiple efforts to understand the reason for the denial and to resolve the issue directly with both the dealership and Kia corporate. Despite these efforts, I was not offered a reasonable solution, nor was meaningful assistance provided. The vehicle ultimately stalled out in the middle of a highway. As a result, I am now left with a non-drivable vehicle and a significant financial burden, including an outstanding loan balance on a vehicle that cannot be used. I am also aware that there have been reported concerns, recalls, and investigations involving engine issues in certain Kia vehicles. While I understand each case is reviewed individually, this raises concern that my situation may not be an isolated incident and warrants further review. I believe this outcome is unfair given my documented maintenance history and the severity of the engine failure. I am requesting assistance in obtaining a fair resolution, including reconsideration of the denial and/or financial assistance toward the cost of engine replacement.

I have experienced chronic and excessive engine oil consumption in my 2021 Kia Sportage S with the 2.4 L Theta II engine. Since around 80,000 miles, I have had to add oil every 2 weeks between oil changes to prevent the engine from running low. My vehicle now requires a complete engine replacement, estimated at $10,000. Despite regular maintenance and oil changes (documented by Express Oil Change in Pinson, AL, with service records at 81,520 mi, 88,215 mi, 94,153 mi, 96,970 mi, 98,902 mi, 101,522 mi, and 105,273 mi), the vehicle continues to lose oil rapidly. Kia and my dealer have confirmed there are no recalls or warranty campaigns for my VIN, even though this issue is identical to the well-documented engine defect affecting earlier Kia models covered under the Theta II engine settlement. This defect creates a serious safety risk, as the engine can run dangerously low on oil between services, leading to engine failure or stalling while driving. I am currently out of work recovering from surgery and cannot afford the $10,000 repair. I am requesting that NHTSA investigate and expand the existing Kia engine defect recalls to include 2021 Sportage models using this engine.

My vehicle is burning oil. In a little over 1500 miles after I get a oil change from the King Kia Dealership Service, my oil stick shows that the level of oil in my engine is none at all. When I check my oil, the stick, is absolutely dry. This has happened in the last 3 oil changes with my vehicle. There is no oil indicator light that comes on in the dash, but the oil stick is dry. Additionally, there is no indication of oil leaking from my car in my drive way. I will be returning to the King Kia dealer service for the third time on 10/13/25 for remedy of this situation. I contacted Kia Customer care and reported this situation and received a case number: [XXX]. I currently have 75,943 miles on my vehicle. To prevent engine damage, I've added quarts of oil to my vehicle to compensate but I'm most concerned that this oil is prematurely burning.

I spoke with their receptionist, Heather on, Thursday [XXX] and she said my insurance company, American Alliance Casualties delivered my vehicle to their facility and they were going to start working on it right away. I called Monday [XXX] to follow up and see how is the progress going to repair my vehicle and she told me that there was something going on with the engine. On Monday [XXX] Heather from Fender Mender Auto Collision called and said my claim was denied because there is wear and tear on the engine. The engine has 27,000 miles from the time it was stolen so that's impossible. However, I spoke with the insurance adjuster Annette Khatib and she said the inspector stated there was a blockage in the engine possibly due to a manufacturer defect.
