I have transferred from a 2012 Ford Taurus to a 2022 Kia K5 which was kind of scary for me but I am so happy that I have made this decision. The car it absolutely stunning and the interior is marvelous.

I spent several months researching details and reviews and test driving the 2023 GT-Line before finally making my purchase. After driving it daily, my initial impressions were all positive, with the exception of just a few not so positive surprises. The car had touted its having four USB ports, but only one is for device connectivity, the other three are for charging only. This was an issue as I keep a massive music library on a 128GB thumb drive that I'd previously used as my primary source of music, but with an iPhone 15 Pro Max connected to the wired-only 10.25" touch screen, I lost the ability to have anything other than the iPhone plugged in at a time. The wireless charing slot is virtually useless, as I have to have my iPhone plugged in via USB all the time in order to use Apple CarPlay. Also, the chrome trim piece that wraps around entire roofline and underneath the rear window looked completely out of place on the GT-Line package (it's the only chrome on the whole car), so I immediately installed matching black-out gloss vinyl to cover it after taking delivery (I was able to purchase a do-it-yourself kit and install it relatively easily for $60 and a half a day's work, vs. the $400+ a local detailing shop quoted to do it). This was a huge aesthetic improvement. The GT-Line should ship this way and eliminate the chrome holdover from the Optima days. Also, know in advance that if you live in cold weather areas, there's no way to hop out of the car and lock the door and leave the the engine running. It shuts itself off you try to lock the car after exiting with the engine running and hit the lock. Forums indicate the only option is to use the remote start to restart the engine after it shuts itself off and you're outside the car. Also, there's no place to grab the trunk to shut it after opening (no notch or handle), so the shiny black GT-Line spoiler is constantly getting covered with fingerprints/handprints from shutting the trunk. Other than those few complaints it's been an overall positive experience owning the 2023 K5 GT-Line after almost 5K miles.

2019 Optima EX vs 2023 K5 GT GT1

I love the power in the engine, i really enjoy the look and feel of the infotainment system. i wish kia would get with the times and have wireless projection of android auto/apple carplay. in my 2019 Optima EX, the lane keeping assist was almost flawless, it was slightly lacking on really tight curves of the highway but i feel that is reasonable. with the 2023 GT GT1, the lane keeping assist is almost dangerous. it seems to have extreme amounts of torque and cannot measure the center of the lane correctly, it is constantly pulling the car out of the lane, especially on curves. The steering assist is even worse... it stays on all the way to zero mph and turns the wheel for no reason at a stop. if you are taking a 25mph TIGHT exit ramp it will GREATLY over-correct the turn and do it extremely quickly, i find myself fighting the lanekeep assist, and steering assist constantly if im not going in a straight line. I do prefer the Harmon/Kardon system in the 2019 Optima as it had a cleaner sound in my opinion. Although the Bose sound is pretty good. also THANK YOU KIA for the remote start on the actual remote. jeez. finally. the only other thing i dont appreciate is how easy it is to scratch the glossy finished trim inside the car. and they got rid of the handle to close the trunk????? Also got rid of the button to open the gas cap??? those were key features i really enjoyed on my optima!

I love everything about this car. The look, the feel, all of it! It drives very smoothly and quiet and is so comfortable. The display is nice and big and perfect for media and navigation. All of the extra features don't hurt either, like the wireless phone charger or KIA Connect App capabilities. I could not recommend this car more. The miles per gallon is also a huge bonus considering gas prices these days!
Honest Review after 1 Year of Ownership

I purchased a 2023 Kia K5. Never owned a Kia before but purchased it mainly because Edmunds rated it top Midsize Sedan. I am a single father with 2 kids so needed a good little car to get the kids around. The styling on this car is slick and looks nice but that's where the good stops. I purchased this car fresh off the truck with 2 miles on it after the dealer was done testing it. I took it home to find out the back passenger door does not lock at all. Of course because it was such a new car the dealer could not even get parts so I had to wait 2 months before it was fixed. Then Kia didn't want to cover it under warranty. After a couple weeks fighting with Kia Corporate I finally got them to agree to cover their own manufacturing mistake. Took 2 days to get the part replaced leaving a bad taste in my mouth with Kia. 6 Months later I checked out my average gas millage and was shocked to find that I am getting only 28 MPG which is almost 10 MPG worse than the 2018 Honda Accord I traded in. 90% of my driving is Highway. That brings us to the present day. Found out my horn does not work. I guess I have never really tried it but today when I really needed it, The horn just did not work. Dealer tells me its not covered under warranty. I give up I am trading this thing in and moving on and will never own a Kia again.
