2023 Kia Niro Electrical System Problems

On multiple occasions, the car has flashed an error on the dash stating there was a problem with the hybrid system. It immediately slows down without time to merge over causing extreme danger on a busy highway several cars swerved to miss the Kia because there was nothing I can do. this has happened several times and Kia is well aware as I’ve had multiple communications with them.

I was driving my 2023 Kia Niro PHEV into my garage after running an errand, going very slowly. Suddenly the vehicle--all on its own--surged forward, slammed into the rear wall (triggering air bags), ricocheted backward across the street, and struck a neighbor's fence. I was able to get out of the car but I was in shock; paramedics were called. Ultimately, my injuries were found to be limited to bruised ribs, but it has been very painful and limiting. The vehicle was towed to a repair shop where it was pronounced a total loss. I received a settlement check from my insurance company, but I am out-of-pocket for the deductible, costs relating to getting a new vehicle, and of course the pain and suffering. I was told there was an event data recorder (EDR) on the vehicle, and my insurance adjuster will tell me what it reveals (I hope). There was no warning of any kind that this was about to happen. I was fortunate that it happened where it did; had I been driving the vehicle on the street, I could have killed someone (including myself).

I received a recall notice SC332 several weeks ago. In February I visited ALM Kia in Perry, GA. The sercice advisor ordered parts, I have checked with ALM Kia several times and they keep telling me the parts have not arrived. This is a serious safety issue and I need your help.

This May of been a cause of a defective Harness Assembly that has taken a few tries to get repaired (Harness is fixed but problem still continues randomly). Since then, my car has stalling problems, randomly, sometimes multiple time in one drive. I have no way to replicate it on my own just that it "can happen" anytime and has subjected me to waiting on the side of the road for the engine computer to "reset" or needs for a tow. Ive been in the dealership at least twice for this with a 3rd this week. Me and the dealer thought it may go away with the new harness installed but it still remains

USB connectivity is intermittent. This involves using the USB A connection in the center console as a port for stored media (music files) on a USB drive and Android Auto. The connection will connect and disconnect randomly regardless of the car being stationary or moving. The intermittent connectivity occurs regardless for all USB cables or thumb drives that I have tried. The vehicle is available for inspection. This presents a safety hazard due to the loss of connectivity for Android Auto while driving and the resultant sudden increase in driver distraction that is generated. Multiple steps and layers of infotainment screen navigation can be required to get to a workaround for music or navigation. The problem has been explained to the dealer service center multiple times but they are unable to replicate it and are explained that they are unaware of the issue on other similar vehicles. Video recordings of the intermittent functioning have been shown to the dealer. Since they could not replicate it, they are unwilling to correct the issue. The issue was first noticed in October 2024 and initially explained to the dealer service in February 2025.

The contact owns a 2023 Kia Niro. The contact stated that while driving at an undisclosed speed, the vehicle suddenly lost significant motive power and was unable to accelerate above 43 MPH. The contact was able to pull to the shoulder of the roadway, where the vehicle briefly returned to normal functionality, but the failure reoccurred. The EPS, stability control, impending collision, Lane Keep Assist, engine oil pressure, check engine, and catch-all warning lights were illuminated. The vehicle was taken to an independent mechanic, who confirmed the warning lights were illuminated but was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was 600.

I was 3 1/2 weeks into a four year lease driving this brand new car and it stopped completely in the middle of the road flashing a HYBRID SYSTEM FAILURE warning. I nearly died. It would not move nor turn off. Had to be in the shop for 2 weeks. I don’t feel safe in this car and I want out of this lease asap. Kia is not willing to work with me on this

The contact owns a 2023 Kia Niro. The contact stated that the vehicle had been "Hacked" by a stalker. While driving, the vehicle was controlled by the hacker to randomly steer to the right. Additionally, the contact stated that the hacker caused several features on the instrument panel to become disabled. No additional information was available. The vehicle was towed to the local dealer, who was unable to determine the cause of the failure. The manufacturer was notified of the failure. The failure mileage was 45.

The components and systems failing are the brakes, adaptive cruise control, smart stop n go cruise control and electrical. Yes it is available for inspection upon request. The auto cruise control doesn’t give a safe distance to stop at (u r close enough to not see there tires) from the car in front of u in case someone hits u from behind. It also doesn’t stop at the same distance it’s set at for the speed distance option. The car also doesn’t emergency brake itself when getting super close to the car in front of u. It only gives u warning sounds n shows that on the dash. I’ve already learned that with my young daughter in the backseat. No not reproduced by dealership Yes looked at by dealership Yes warning sounds n an alert on the dash but no action from the car. My car is brand new!!! Auto cruise control works great when the car is moving, but when utilizing “stop and go”, the car stops way less than 1/2 a car length from the car in front. A dangerous distance anywhere in my opinion. Changing the following distance does not change this stopping distance behavior. The dealership/s have been no help with most of the techs describing the stop and go feature as not stopping (Its the older models that have had this type of ACC, where the driver has to stop the car) So if they can’t understand the issue, there is no way to get them to correct the issue. I have found other drivers with similar issues so I know I’m not the only one. But I am the only one taking to time to say and do something about this huge safety problem for a brand new car.

1st noticed when parking car, beeping from control panel as if touchscreen buttons were being pressed when they were not. Day or 2 later, AC and/or heat started coming on randomly, would not turn off, all touchscreen buttons illuminating as if pressed. Dealership found crack in screen. No knowledge or memory of any impact to cause damage. Dealership refused warranty coverage. Controls unusable and screen is glass, so there is now broken glass all around controls. Crack spread and expanded during normal driving conditions over next week. Control panel affects multiple other screens that should display information needed while driving. Problem mostly stopped after crack expanded more after I hit a pothole. Started again recently. Glass is badly cracked and has gotten worse with temperature changes that should be expected when a car is parked in the sun, and due to vibrations while driving. Control panel now entirely unresponsive. This panel is far too fragile to be in a car. There was no accident or incident prior to the initial problem. It seemed to happen spontaneously.
