I haven't driven any K5 except my 2023 GT-Line, so I can't compare them. I had a 2019 Optima that I bought from a dealer with 8,000 miles on it. It had a problem with the accelerator "drive by wire" system that the dealer could not - or would not - fix. After 22 months of the car stalling when I would try to accelerate - several near death experiences - I threatened the dealer with filing formal complaints with NHTSA, Kia Corporate, our state's Attorney General's office, and the Better Business Bureau, the dealer gave me the brand new (12 miles on the clock) K5 GT-Line in an even trade to, as the general manager said, "To show you that we always try to do the right thing." It took them only 22 months for them to "do the right thing." The dealer I work with now in Durham, NC is amazing - honest, professional, keeps schedule promises, and charges fairly decent service fees.

If any Kia owner is experiencing the engine continuing to run, but not accelerating when the accelerator is depressed, make the dealer test the fly-by-wire accelerator components one at a time to isolate the problem. Kia knows about the problem, but hasn't decided to do a recall as far as I know. I haven't experienced this with the K5, so maybe they corrected it at the factory when they did the Optima to K5 changeover.

How do you feel about the overall value of the K5 GT-Line compared to other vehicles in its class? Checked out the Sonata by any chance? I think that's what a lot of folks pin it against.

Well, I bought my 2024 K5 GT-Line, Pre-Owned at 5,000 Miles, @ 9,963 Miles, it had Preventative Maintenance, Work Done: Oil and Filter - Change, Complimentary Multi Point Inspection. Check and inspect all fluid levels. Visually inspect all belts and hoses. Check tires and brakes and document measurements. MPI Complimentary Multi Point Inspection. Check and inspect all fluid levels. Visually inspect all belts and hoses. Check tires and brakes), it’s now @ 11,000 Miles… Car has been stellar

Great to hear that your 2024 K5 GT-Line has been performing well so far with only preventative maintenance. Did you get your first oil change done at the interval that Kia recommends or did you do it sooner? Are you following maintenance by the book?

Got 45k on mine. No issues.

Is yours also a '21? What trim/configuration?

The 2025 Consumer Reports Buying Guide - Automobile section - lists reliability ratings of used cars; and gives predictions on reliability of new models. This is based on thousands of surveys completed by owners. The 2022 K5 didn't have enough responses for valid conclusions. But there is complete data on the 2022 and 2023 K5. Info is not yet available for the 2024 and 2025 K5s. The 2022 K5 gets an average reliability rating with build quality as average and "minor transmission problems" and brakes being much worse than average. Every other item on the 2022 is rated as much above average. The 2023 is rated much above average on every single item except in-car electronics, which is rated above average. My 2023 K5 GT-Line verifies this info - not a single problem in 2 1/2 years of ownership. I'm a long-time car nut, restorer, former amateur racer, engine builder, etc. So I maintain my vehicles fanatically - which I recommend for any piece of equipment.

I hope this helps answer your question.

Great insights from the CR guide. Glad to hear that your 2023 K5 GT-Line has been performing well without any issues. Have you noticed any differences in the driving experience or build quality between the 2022 and 2023 models?

If you're going to go with that idea let me share another...
Typically people join k5owners to vent about their K5's problem(s), and are seeking answers or fixes.
Those types of posts are few - so that would indicate they're not having serious issues.

Valid point. Took a deeper dive into this to realize that Kia/Hyundai are right on par with Honda and Toyota, and even ahead of them. Quite impressive seeing where they came from.

So much for that Hyundai diss in Tokyo Drift, haha.

My 2024 GT with the 2.5 turbo has been less then stellar in reliability. Bad fuel injector, a spark plug that failed, door handle lock button repeated issues. And my experience with my local Kia dealer service department has been shall I say, less than reassuring. I have made the decision that I will NOT own this car beyond the 10 year/100,000 power train warranty. Probably go back to Honda. Have you seen the look of the upcoming Prelude? Sexy!

Thanks, sorry to hear about the issues you've faced. Had a chance to discuss your concerns with the dealer? How likely are you to switch to something else? Honda did just release a new Civic Hybrid, I think it runs a system similar to the upcoming Prelude.

Thanks. I was hoping to hear some more recent takes on reliability because most of it on this forum are 8+ months old, but of course still relevant.
