KIA Complaints

The ICCU charge control unit for Kia electric vehicles that immediately depletes the 12v battery & significantly reduces motive power forcing you to pull over with no countdown to how long one has in terms of distance or duration. This uncertainty is absolutely unsafe as you cannot know how long it is safe to keep driving before the vehicle ceases to move. This ICCU failure has been affecting several 2022 onwards Kia vehicles & even replacing this component does not guarantee this failure will not recur & needs serious action & accountability to Kia.

I own a 2020 Kia Sportage that is currently within the 100,000-mile powertrain warranty. The vehicle has been experiencing EXCESSIVE oil consumption, requiring oil to be added between scheduled oil changes, despite no visible leaks or warning indicators. I have consistently maintained the vehicle according to Kia's recommended maintenance schedule. Oil changes were performed regularly, including some done at home. For those oil changes, I have provided bank statements showing the purchases of oil and filters from Autozone, which is a valid form of maintenance. There is NO evidence that improper maintenance caused the oil consumption. The vehicle was kept by the Kia dealership for 18 days during their evaluation. Despite providing documentation and cooperation throughout the process, Kia denied my warranty claim. Denying warranty coverage solely due to oil changes performed at home is not consistent with the Magnuson-Moss Warranty Act, which requires proof that improper maintenance directly caused the failure.

While driving, heard a pop and a check electric vehicle system error popped up on the dash. Car was not drivable except for very low speeds shortly after (impacted safety of the drive) until it eventually stopped being able to turn on at all.

6” Snow ice storm & negative degree temps 12/13/25 used heated windshield deicer. On 12/15 driving to work on a country road no other traffic, heard pop cracking noise above my head checked sunroof snow ice melting no visible cracks thought noise from thawing ice. Parked vehicle in my home garage while I went out of town. Returned home 12/22 found large crack origination point in front windshield originating in glass down the middle of rear view mirror sensor housing black box mounted on inner windshield the crack spans from top middle to bottom of black box glass over to right center half of windshield. Believe this is a manufacture defect design flaw low quality integrity of glass weaker than standard glass making it more susceptible to temperature changes or minor impact. Entire crack feels smooth interior exterior glass as if the crack is in the inner layers of glass windshield. Due to multi complaints & prior class action lawsuit regarding manufacture defect of KIA windshields I am reporting my complaint as it is quite similar to others complaints, issues & lawsuits. The massive crack in windshield is a driving safety hazard & a manufacture defect that needs recalled & resolved before injury or death occurs. KIA must acknowledge, issue recall &/or post a bulletin, accept responsibility this is a manufactures defect, notify the public and replace the windshields under Good Faith Customer Relations Warranty

1) What component or system failed or malfunctioned, and is it available for inspection upon request? The panoramic sunroof assembly — specifically the sunroof panel and its track/mechanism — failed. The sunroof panel came off its track and damaged related components (e.g., guide rails/wind deflector arms). The damaged sunroof and broken parts are available for inspection upon request. 2) How was your safety or the safety of others put at risk? The sunroof panel dislodged unexpectedly during normal use. This could have caused objects or glass to fall into the cabin or onto the roadway, presenting a risk of injury to occupants or other road users. Sudden failure of the sunroof mechanism also poses a distraction while driving. 3) Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The dealership/service center inspected the vehicle and confirmed the sunroof panel was off its track and broken. (If the dealer refused to acknowledge it as a defect, state: “The dealership inspected the failure but did not classify it as a warranty defect.”) 4) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle/sunroof was inspected by an authorized Kia dealership service department. (If applicable: “Insurance representatives were not involved.” / “Kia corporate has not inspected the vehicle.”) 5) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages prior to the sunroof failure. There were no abnormal noises or operational symptoms immediately before the sunroof panel disengaged from its track.

The ICCU failed in my car while attempting to charge the vehicle while at home in my garage. This component has a known history of failure while driving and now that it has been replaced with an identical unit, I fear for my safety while driving since I live in a remote area and rely on the car for transportation in sub-freezing temps and winter conditions. While the dealer has replaced the ICCU, there is no acknowledgement from the manufacturer that the failure mode of this component has undergone any redesign or improvement to warrant trust that it will not happen again. It is a ticking bomb.

The contact owns a 2025 Kia Sportage. The contact stated that while attempting to start the vehicle, the engine experienced difficulty cranking. Additionally, the contact stated while driving at an undisclosed speed, the transmission failed to properly shift gear. The contact stated that the engine revved up, but the transmission failed to properly shift gear. The Auto START/STOP light was orange. The contact was concerned about a possible disintegration of the transmission after a friend alerted him of a similar failure. The contact called the local dealer and left a message. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 18,000.

Kia has a known ICCU issue with several of their electric vehicles. Mine went out yesterday creating an extremely dangerous situation on the road. After it blew, I lost the ability to accelerate or steer. This was obviously very scary for me and the drivers around me. I feel very lucky to have not been hit by another car. Although Kia is replacing these, this does not guarantee a fix. That is to say, the ICCU has the potential to blow again after replaced because the core issue is not something that Kia group has reengineered. I should not have to fear getting into my vehicle and wonder if it will blow again. I hope the government steps in and conducts an investigation into this. It’s only a matter of time before someone, unfortunately, will lose a life over this.

I am submitting a safety complaint regarding unexpected and inappropriate automatic braking behavior at low speeds involving the parking sensors, rear cross-traffic alert, and/or automatic emergency braking system. While performing normal, low-speed maneuvers such as backing out of street parking spaces or parking in tight urban environments, the vehicle abruptly applies the brakes even when no imminent collision exists and when obstacles or traffic are clearly visible to the driver. In one frequent scenario, while exiting a parallel out of a parking spot into traffic, the vehicle suddenly stops itself while partially in the roadway due to a car approaching in the rear. This occurs despite sufficient clearance and approaching vehicles slowing to yield or even happens AFTER the approaching vehicle has passed already! This creates a dangerous situation where my vehicle is immobilized in active traffic, increasing the risk of rear-end or side collisions. The driver behind me sees me stopped in middle thinks that I'm waiting for him, when really my intention was to come out of the spot and then finally it releases the emergency brake and then my vehicle juts out into the roadway. Also, during parking maneuvers, the vehicle applies emergency braking despite having enough space, SLOW speed, & the driver having full visual awareness via the backup camera. This removes the driver’s ability to make precise low-speed adjustments. The override behavior is also unsafe. Regaining control requires a firm brake press, after which releasing the pedal causes the vehicle to move abruptly, eliminating precise control and increasing collision risk. This behavior is unpredictable, inappropriate for dense urban driving, & creates hazardous situations rather than preventing them. I believe this constitutes a safety defect in the vehicle’s braking and driver-assist systems. Concerned this could lead to serious accidents, particularly in urban environments. Friends have same problems!

The ICCU that charges the 12V on board battery failed to keep the battery charged and it made my vehicle a paper weight. Had to have it towed to my local Kia dealership to wait 2 weeks for an appt. Hasn’t been repaired yet and I’m sure it won’t be a short wait after they schedule the repair
