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.

May 06, 2026

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

My car is burning oil like crazy. I’ve had to put 2 quarts in one week. Took it to dealership because of warranty. They ran an oil consumption test and told me pistons may be bad drive it another 1000 miles then we check it again. Why not fix problems then. So I have to check my oil every day until they want to do the work I guess

The infotainment system has bubbles, and it interferes with touch screen process. I have seen lots of people that have different KIA's that have the same issue. This should be considered a RECALL due to how so many KIA's that have the same issue.

Jul 11, 2024

My Kia can be easily broken into and stolen. In January of this year I was in Denver for military assignment and I locked my car at night however a their was able to break into my car by popping off the driver side lock and then basically hot wiring the car. Eventually I got my car back after it was repaired but then again someone broke back Into my car using the same method. However, I had a steering lock so they could not drive away. The security and safety features on my care are worthless and do not provide the security a modern car should.

Aug 04, 2022

The car was stolen and no safety/security features were deployed. In doing research, Kias are being stolen on a daily basis in my city and this was not communicated to me by the dealer when I bought the vehicle 6 months ago. These cars should not be allowed to be sold without steering wheel locks and/or signed acknowledgment by the buyer. They clearly do not have the necessary equipment or features to prevent them from easily being stolen.

On Thursday [XXX] I purchased a 2021 Kia Sportage LX from Liberty Auto Plaza Dealership located in Libertyville, IL. During this purchase, the salesman Isaac told me the car was updated with Anti-Theft Protection. Between Friday [XXX] evening and Saturday [XXX] my Kia Sportage that I just purchased was stolen. I called the police department and made a police report and I filed a claim with my insurance company, American Alliance Casualties. My vehicle was recovered on Wednesday [XXX] and the insurance company picked the vehicle up on Friday [XXX]. My insurance company, American Alliance Casualties has had my vehicle since. [XXX] will be five months this company has had my vehicle. On [XXX] American Alliance sent me an Offer Letter to, either have the vehicle to be repaired or, have a direct check sent to me. I choose to have the vehicle repaired because I wasn't looking for money I wanted my car repaired. The company I chose was Fender Mender Auto Collision Center. 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.
