KIA Complaints

For several weeks the car has felt out of balance and I had it in the shop once to be balanced. The balance felt it lasted a very short time. I took the car in today to be checked out and the passenger rear tire couldn’t hold a balance. Mechanic removed tire and the interior sound deadening foam had detached on greater than 50% of the diameter of the tire. This has been widely commented on as a common failure mode for these Hankook tires on EV9 vehicles. I wanted the remaining tires inspected but as they would hold a balance the dealer had no reason to put in the labor of removing and inspecting the foam. 285/45 R21

My vehicle has been in the shop 7 times for misfire in all cylinders over a 2 1/2 year span Kia dealer refused to replace the engine, 8 months after I threatened to sue the dealership for saying they fixed the misfire in all cylinders issue and 8 months later I’m getting misfire in 4th cylinder. As the engine light came on again and I have a high end car diagnostic tool attached to the car which is giving me that code and previous codes of misfire in all cylinders. First misfire in all cylinders started at 16,000 miles bought car brand new and it continued all the way to 37,067 miles . The Kia dealership keep saying it’s this or that and it’s been fixed but the lights come on the previous 7 times after a week or less after taking it home from the dealer and then saying it’s fixed last time I wanted a new engine a Kia representative said it doesn’t need a new engine. I talked to a technician there about reading about this issue in alot of same vehicles he said I was right but Kia doesn’t want to pay for a new engine so they give excuses or just reset or clear the codes which doesn’t resolve the problem , Kia has changed the fuel tank, changed the spark plug wires, the spark plug cables the assembly,ecm which never resolved the problem

While driving at night with the Headlights on Low Beam the light that is projected onto the road is a dull yellowish color, not a bright white color. When the High Beam Lights are turned on there is no difference of the light being projected onto the road. While driving from [XXX] to [XXX] on [XXX] I noticed that I was unable to see or read the Exit Signs for any of the Exit Off Ramps or even the Mileage Signs the show the mileage to the next Towns. When I switched from Low Beam to High Beam it made no difference on Illuminating the Road Signs. When I returned to my home I took the car into the Kia Dealer with the complaint that the Headlights were not working properly. They adjusted the Headlights up higher, so now the Low Beam did Illuminate the Road Signs, but they seemed to High and still had the yellowish color. When the High Beams were turned on it still made no difference in Illuminating the Road. Again I took the car back to the Kia Dealer and they Readjusted the Headlights back to what they said was the Factory Settings. I was then told that if I was not satisfied I could try purchasing some Aftermarket Headlight Bulbs from an Independent Parts Store. This is an Unsafe Condition because I can't see obstructions that may be in the roadway and have enough time to safely maneuver around it. Since this happens at Night the Dealer doesn't have personal to replicate the problem due to the Dealer Service Department is only open during daylight hours.

The electronic parking brake controller failed after intermittent warnings that began while the vehicle was still under warranty. The parking brake actuator also failed and had to be replaced. The electronic parking brake system is part of the vehicle’s safety system, and the failure caused the parking brake to malfunction unpredictably. The issue did not store persistent diagnostic codes, making it difficult to diagnose earlier. This is a safety concern because it affects the vehicle’s ability to hold position when parked and can interfere with braking and stability control. Because I am not the original owner, Kia refused to perform this as a warranty repair even though the intermittent failures began while the vehicle was under warranty.

MY 2016 KIA SORENTO ROLLS OUT OF PARK; I APPARENTLY HAVE A SORENTO THAT IS "OUT OF THE DATE RANGE" OF THE 2016 KIA SORENTOS THAT HAD A RECALL. THIS IS NOT ACCEPTABLE!!!

My 2016 Kia Optima equipped with the 2.4L DOHC I4 GDI engine began to experience progressive and severe oil consumption during the latter part of my ownership. The oil warning light began activating repeatedly, even after shortly getting the oil changed. Several certified mechanics and oil change service stations told me this was an ongoing issue with this car and engine and that there was nothing I could do but monitor it and keep it filled. At their instruction, I monitored and had it changed more frequently, often topping it off at the oil change station and at home when needed. Approximately 2 weeks after an oil change upon putting the car in reverse it started to shake uncontrollably. The car was towed to a mechanic who stated I needed an engine. I then towed it to an authorized Kia franchise dealership where the technician documented the oil consumption complaint, confirmed a Cylinder 2 misfire code, performed a borescope inspection, and found the Cylinder 2 exhaust valve burnt with a chunk missing. Engine replacement was recommended by the Kia dealership technician. Prior to my purchase, the engine had already been replaced at approximately 80,000 miles under recall-related circumstances. The replacement engine installed by a Kia dealership subsequently failed, exhibiting symptoms consistent with the documented widespread defect affecting the 2.4L DOHC I4 GDI engine in 2016 Kia Optima vehicles, including severe oil consumption, cylinder misfire, and catastrophic internal engine damage confirmed via borescope at a Kia franchise dealership. Kia America denied the claim based solely on mileage despite the damage being confirmed by their franchise technician. My vehicle became unsafe to drive due to this engine instability shortly after starting before becoming fully inoperable. My vehicle has been non-operational for approximately 5 months. Kia has not provided a substantive written determination despite a formal written demand submitted in March 2026.

Van made a loud pop noise and lost power. The HSG belt tensioner spring fell off it's seat loosing tension on the HSG belt. Was unsafe but luckily it happened before getting on the freeway, and coasted into a parking lot. Yes, it's at the dealership getting a replacement tensioner and belt. I believe so. No notification prior to failure, it was sudden.

Cluster that shows speed/gas/safety notifications has went completely black and will not turn back on. It has now been in the shop for 2 weeks and they cannot figure out why this is happening. This is the second time the instrument cluster has went out on the 2024 Kia Telluride.

My 2017 Kia Sportage has experienced excessive oil consumption, cylinder #3 misfires, loss of power, and highway stalling events. The dealership initially documented engine damage and indicated findings consistent with internal engine failure, including concerns related to metal contamination and cylinder damage. These issues appear consistent with numerous complaints from other Kia owners involving the same engine family. Kia has since backtracked on prior findings, and both Kia and the dealership have stopped responding to my requests for clarification and documentation. The cylinder damage and related engine failures appear to be symptoms of a larger engine defect that poses a safety risk due to sudden loss of power and stalling while driving. I request that NHTSA investigate these recurring engine failures and Kia’s handling of these claims.

Window regulator failure - power window could not be rolled up. Had to be replaced.
