4.0out of 5 overall- 5.0
Best midsize sedan ever!!!
by Anonymous Reviewer on 7/22/2025 10:02:42 PM
I have 2022 kia k5 gtline with 90k kms on it. I never had problem with this car except 2 times, one for reverse camera (changed for free), and one for throttle body valve( again for free). Eventhough I don’t like 2024 k5 headlight design, 2022 k5 is amazing. For some reason the depreciation was very less than expected. After 50k kms on the car I got quote for $39k. - 4.0

Only thing I dislike about the car is how the seat go back automatically when car turns off which is the most dumb thing you can do cause if someone behind me the seat presses into the legs and I just broke my snake cage cause because the seat literally press into it and broke the glass now I got to pay 200$ on another snake cage because of a dumb seat like why make it automatic and for the seat go all the way back like that like nobody sit in backseat or stuff in the backseat now it done broke my snake cage because the seat automatically went back and shattered it
