KIA Complaints

The contact owns a 2016 Kia Optima. The contact stated that while driving at an undisclosed speed, the vehicle shuddered. No warning lights were illuminated. The vehicle was taken to a dealer, where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and stated that the knock sensor needed to be installed prior to the failure for the engine replacement to be covered under warranty. The failure mileage was approximately 143,000.

ICCu failed. All the symptoms others have reported and discussed. (Reddit Kia subreddit + Kia Fotum). Sent home unable to charge. Kia claimed they could charge and wouldn’t do anything. After the second trip to the dealership they said “ it kick d out a ICCU code so we can replace it now”. They knew it was bad and the warranty protocol stinks. Software update did not prevent this. A fix and extended warranty should be required.

Kia 2022 EV6 41,238 miles. The ICCU failed and was towed to KIA dealership. It was covered only because we got the extended warranty. Was at 88% charge, dashboard lit up with the warning “Check electric vehicle system”. Loss of drive power increases the risk of a crash.

Certified shop said my timing chain was going as well as other associated components. My car is always low on oil even when mileage has not been met. Found my car is part of piston ring recall. Dealership stated my car is not affected however the issues the shop found most certainly confirm my issue which is going to cost over $2k to fix is associated with this. Dealership not only says my car passed piston ring recall but wanted $175 to diagnose what has already been diagnosed and then another $175 on top of that to "dig into the engine". Check engine light came on and car began making noise and not running properly on 2/7/2026 on 2/9/2026 called independent service center and car was checked out and diagnosed on 2/11/2026. Found out this is likely recall related 2/12/2026. Car was looked at by dealership on 2/17/2026 and I was told the aforementioned. However magically the two other recalls on this vehicle were remedied but not this one.

Paint is peeling off all over my car. I see this is a known issue with the white paint and nothing is being done about it. I have touched up a few spots but it is only getting worse

I believe my car has been burning oil. The oil was empty at our last oil change only about 60,000 miles on car and we have had to keep adding oil to the car since then. I got extra concerned also when I saw alot of kia souls same year have gotten recalled for oil consumption, yet my vin number wasnt included... I have dropped a document in the comments with what the dealership said about it as well.

Car is burning over 2 quarts of oil every 1000 miles with no leaks, stalls at stop signs and lights. Engine needs to be recalled. No warning lights.

Steering has a "sticky feeling". While driving, when you try to turn steering wheel a fraction to one side or the other there is resistance and then a release which results in in oversteering that has to be corrected. When trying to correct the oversteering, there is again resistance and then release with oversteering again. So it constantly goes back and forth. There is a string of posts on [XXX] " with owners of the Kia Sorento having this same issue. Not only is this annoying but also unsafe. This has been going on since about summer of 2025. I do not driver this vehicle very often or I would have gotten on this issue sooner. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
