KIA Complaints

No FireNo Injuries0 Deaths0 I’m experiencing severe oil consumption and spark plug fouling, which are known problems with the GDI engine. This is affecting driveability and may indicate piston ring or valve seal failure. My engine code starts with G4KJ which falls under the current recall, but my vin does not show up. Why isn't my car eligible? I have called Kia and their response was to call my local dealership. Started noticing the issue on [XXX]. Called dealership at that time and they said my car doesn't qualify. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Electrical issue all dash lights came on and couldn’t shift into gear, had to replace my main computer as it was fried at 72,000 miles, also had to get the steering column replaced total of $6,000 fixes

Burning oil, not wanting to accelerate properly on the freeway, kia has engine in previous years having the same issue, and these 2020 and they are not trying to fix them.

I am submitting this complaint regarding ongoing and unresolved safety issues with my Kia K5, which I believe are directly related to a known recall involving the ECM (engine control module) and/or fuel system. My vehicle continues to jerk and misfire during acceleration, and it has even stalled at idle on multiple occasions — creating a serious safety concern for myself and others on the road. I have already completed the recommended repairs, including new ignition coils and spark plugs, yet the problem persists. Despite these symptoms aligning with known recall-related issues, Kia of Orange Park (Florida) has refused to fully diagnose or investigate the matter, citing that the recall does not apply in my case. However, the symptoms match those outlined in other ECM/fuel system-related recalls, and this is not the first time this dealership has failed to properly address mechanical concerns. Previously, I had to escalate an A/C issue to Kia Corporate, which only resulted in a resolution after a recall was issued right before my vehicle was set to be returned with the same issue. That situation makes me extremely concerned that my current safety concerns are again being ignored and will only be addressed after a broader recall is issued. I am requesting that the NHTSA investigate this matter, as I am worried this defect may affect other vehicles and poses a safety risk that Kia and its dealerships are not taking seriously. Thank you for your attention and action.

The oil light flickered on and off intermittently despite oil in it and was making a cackling noise during acceleration for 2 days then my engine made loud screech noise and smelled like burnt oil and shut off . I had it towed to a mechanic who stated it showed a hole in the engine block .

Sunroof would not open or close properly. Dealer said arms broken. Need entire new sunroof at over $5000 plus labor! To replace just these small pieces. The glass is out of the track and taped down. It is a dangerous fix. I cannot understand why Kia won’t fix with it being a known malfunction of sunroof mechanism assembly according to TSB. I am out of warranty by 6 months. I contacted Kia and this was their response. Need help please.

ICCU failed while charging using Level 2 charger. Dealer still has my vehicle and issue was diagnosed.

It feels like the engine is starting to cut out and as soon as that happens, the electronics in the car seem to start fighting each other. They adaptive steering and the lane assist it feels like they don’t work together anymore and I’m always fighting it or it won’t stay in the right lane and the car jerks from line to line. If I turned the lane assist off then it drives OK but the engine still is doing something funny.

1- ENGINE It’s been about 3 months that when I depress the gas pedal the car skips or hiccups and I get a check engine light on I have to accelerate slowly this also happening while I am driving it’s worse if I try to pass a car

On or around [XXX] the rear occupant sensor warning light came on. We scheduled a service appointment with the dealership for 7/15/25 at 7:00 a.m.. We were informed later that morning that it was a defective module that could affect the air bags and it wasn’t safe to drive the car. It is 7/26/25 and we still wait on the part. Yesterday we were told by the service department that they didn’t know when the part would be available, it is back ordered due to the number of vehicles with the same issue. While our car waits at the dealership we got an email from Kia Connect giving us a 12 volt battery discharge warning. We don’t know if this is related or not but when looking online we found several people with that same problem as well. Our mechanic agreed that the 12 volt battery should not be discharging that fast due to just not being driven. The car sits at Russ Darrow Kia in Madison WI where parts and other information should be available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
