What Owners are Saying About the 2026 Kia K5
"Much improved over 2013 Optima I previously owned."
"Owned a 2013 Optima EX prior, the 2021 K5 LXS AWD is much improved. And I really enjoyed my 13 Optima. Only drawback is the rear window, could be improved with a rear wiper like the Audi 5."
"Bought for my son, I’m super jealous"
"Got this car for my son, wanted something safe and great warranty. Cool factor for a midsize car is off the charts. I think Kia has a winner on their hands with this GT Line. Car has just the right amount of power to get up to freeway speed without getting in to trouble. Lots of safety and tech features make it a winner in this price range"
"Decent Car"
"To be a new car still with only 18500 miles on it. It was just average. It had several issues in the first 2 years that I didn't think should have been OK and there was no recall. The transmission would have trouble shifting in Smart Mode because the computer couldn't make up its mind what to do. So it might try to throw you backwards or forwards depending on its choice at lower speeds."
