2020 Kia Sportage: problems, recalls and reliability

“The car shook and lights came on at a stop light and began violently knocking. Since it was at a stop light the safety was a risk had the hazard lights weren't engaged immediately. The dealer confirmed it was a catastrophic engine failure. An inspector for the warranty company was deployed two times. The lights only appeared at the time of engine failure.”Owner report · Engine · Apr 2026

“Odometer Fraud. The contact purchased a 2020 Kia Sportage. The contact discovered a mileage discrepancy after the purchase. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 70,000. It was later discovered that the mileage on the Title was 107,000 while having a routine oil change. The service records indicated that the mileage had been altered.”Owner report · Electrical System · Feb 2026

“The contact owns a 2020 Kia Sportage. The contact stated that upon starting the vehicle, the engine made an abnormal knocking sound. The vehicle was taken to the dealer, where it was diagnosed with a cylinder #4 misfire, a knock sensor, and bearing clearance measurement failure. The dealer informed the contact that the vehicle was not covered under warranty because the warranty was on the vehicle with the previous owner. The dealer contacted the manufacturer and was advised that the repair could not be covered under warranty because the failure was considered the consumer's negligence. The vehicle was not repaired. The failure mileage was approximately 82,000.”Owner report · Engine And Engine Cooling · Feb 2026

“In April of 2025, it was noticed that my Sportage was consuming oil. There were no leaks or smoke just having to put oil in. Two mechanics stated that's just Kia. On the night of 1/30/2026 my Sportage had an engine light come on. After the winter storm, I was able to get the code read and it came back as a Cylinder 1 Misfire. In May of 2025 I replaced all coil packs and spark plugs. On 2/1/26 we replaced the coil packs and spark plug. On 2/4/2026, Kia told me I have to replace the engine. I am still paying the vehicle off. This does seem to be an issue with Kia engines 2.4 from what I'm reading.”Owner report · Engine · Jan 2026

“I came home from vacation and found my car completely dead. We took the battery in and ended up changing this. Soon later my cars power steering and dashboard would go in and out. I took it to Mark Kia who believed it to be the alternator, so they replace this. I picked the car up and not even 20 minutes later the same issues were occurring so I took it back where then they replaced the connector. I picked up my car and about a month went by and same thing occurred while I was driving even having my car completely die while driving it. I took it back in and now they believe it to be the engine harness.”Owner report · Electrical System · Jan 2026

“Driving to grandmas Christmas weekend on the highway all of a sudden my car couldn't keep speed was shaking the check engine light came on. Now my cylinder one psi is only 50. I have noticed over 100 complaints with very similar car issues. I just bought this car 5 months ago from a dealership. I have barely put 4,000 miles on the car myself.”Owner report · Engine · Dec 2025

The dealer was contacted; however, the vehicle was not diagnosed or repaired by the dealer. The manufacturer was made aware of the failure.
