Consumer Reviews for the Kia K4
Read recent reviews for the Kia K4
Amazing value
user167, 12/16/2024
2025 Kia K4 GT-Line 4dr Sedan (2.0L 4cyl CVT)
I previously drove a 2017 Elantra limited (156k miles) and it never gave me a single issue. I gifted it to my grandmother as her car died. I bought the K4 as I wanted red seats and all the new technology. This car rides better than my Elantra because of the independent rear suspension. Gas mileage is great and I’m really enjoying the car. I hope the K4 will be as reliable as my Elantra. … The wide sunroof is also a plus, makes the car look extra sleek cruising around town with it open. I have gotten a lot of compliments and definitely recommend!!!
