Kia Niro 2025: Retiros, Quejas y Ley de Limón de California

I believe the issue is related to something connected to the AC system or a component underneath the hood. The exact part that malfunctioned has not been confirmed. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because some kind of leak or fumes were being sent into the car through the AC vents, causing myself and others in the vehicle to feel sick. I have taken the car to 3 Kia Dealerships. All of which have been extremely dishonest (have tons of proof) and say they cannot verify problem. I took it to an outside independent shop and they verified it instantly and wrote a very detailed invoice about the problem. They couldnt pin point where it was coming from though. The vehicle has only been inspected by the 3 Kia Dealerships and the independant shop Brake Busters I purchased the car in November of 2025 and had no problems until February 22nd 2026. No warnihg lights or messages came on prior. The symtoms that started were Nausea, Headaches, light headedness, vision blurry, and almost caused me to pass out at wheel several times.

On now 4 occasions--intermittently my car will go into drive when shifted into the reverse shift I don't know what component is impacting this. My safety and others safety is at risk by my car literally going forward when it's supposed to be in reverse. I've taken my car to the dealership two times and they have not been able to recreate it or fix anything. I've reached out to KIA corporate for a resolution but have not gotten follow up: Case#XXX (case where I was supposed to get a response from a case manger) and XXX (original case). To my knowledge I don't know if it's been inspected by the manufacturer, police, insurance representatives or others No warning lamps or signs. It happens intermittently and seemingly no rhyme or reason when it happens. This happened back in November 2025 and most recently this April.

On November 3, 2025 I had an accident/event in my KIA Niro. At 2:20 I had been sitting in my car with the engine running and the gear was in (P) park. I was on an incline. When I saw the child I was babysitting ‘s bus arrived, hopped out of the car (it was still running) and walked behind the car, and stood waiting for him. I told him to hold on and we would go inside after I grabbed my phone and turned the car off. I opened my drivers side door to grab my phone, when the car started moving very rapidly backwards. I made every effort get control of the car but I was unable to, as I was hanging half in half out of the car. I collided with a Toyota truck, and damaged the passenger side rear bumper and lights and the side panel on the passenger side. It all happened immediately after I opened the driver side door. By the grace of God my charge and myself were not hurt, as we were standing directly behind the car moments before I went to turn off my engine and get my phone.

The contact leased a 2025 Kia Niro. The contact was stopped at a traffic light during the night. When the light changed, the contact was partially turning when the other vehicle slammed into the contact's vehicle. No injuries were reported. The contact stated that the front collision sensor failed. The contact was not warned of the impending collision. The driver-side and passenger-side air bags did not deploy. The vehicle was taken to the collision center. A police report was filed. The contact believed that the sensor failed in the evening and worked as intended during the daytime. The insurance company was notified of the accident. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,500.

I am reporting a serious safety concern regarding the 2025 Kia Niro Hybrid and its adaptive cruise control system. When the cruise control is activated and set to maintain a certain speed, the vehicle continues at that speed regardless of whether there are other vehicles in front of it. In multiple instances, the car approached slower-moving vehicles at 45 mph without reducing speed or giving any warnings. There was no automatic braking or even a prompt to alert the driver of the imminent danger. This is extremely dangerous and could easily result in a rear-end collision if the driver is not fully alert. It is especially surprising because the same vehicle features intelligent climate control functions—such as adjusting fan speed during phone calls and preventing windshield washer fluid odors from entering the cabin while the A/C is running. Given the level of attention to such minor details, the lack of basic forward collision mitigation behavior is unacceptable. The issue was reported to a Kia service center, but no clear explanation or resolution was provided. I believe this may be a software bug or a design oversight that has not been properly acknowledged. Recommendation to other drivers: always keep your eyes on the road and be ready to intervene, even if the adaptive cruise system is engaged. The risk of collision is high if you rely on the system to slow down for vehicles ahead. This needs to be investigated immediately before it leads to serious accidents. I urge the NHTSA to review this issue and, if necessary, request a recall or software update from the manufacturer.

Situation: Slowing on exit lane from freeway while in I-Pedal mode. Anomaly: As i gradually lifted the accelerator pedal, at about 61 mph the car strongly accelerated. My response: I lifted my foot entirely off the accelerator pedal and scanned the dash to confirm that cruise control was not active. Acceleration continued. I tapped the accelerator pedal and the acceleration stopped. We were now at 69 mph and close to the car in front of us.

Transmission was replaced but then completely shut down as I was making a right turn. Multiple indicators on dash went off and safety errors kept scrolling across dash. Vehicle then wouldn’t shift at all. TCM was replaced but vehicle has high RPMs at low speeds. Has been at the dealership now for over 90 days.

I visited Car Pros Kia Tacoma for a wheel alignment on my 2025 Kia Niro EV. After the service, I was told the alignment was completed correctly and I was given a printout showing all values in the green. However, the vehicle did not feel stable or safe to drive afterward. The steering felt off, and the car did not track straight. Because the vehicle felt unsafe, I took it to Firestone the next day for a second opinion. Firestone performed a full alignment check and their “before” measurements showed that the alignment was significantly out of specification, including major issues with front toe, rear toe, and thrust angle. These values were far outside normal ranges and could affect handling and safety. Firestone then corrected the alignment, and their “after” measurements showed the vehicle was properly aligned and driving normally again. Their report clearly shows the difference between the unsafe alignment I received from Kia and the corrected alignment they performed. In summary: • Kia performed an alignment that was not actually within proper specifications. • I was told the alignment was correct when it was not. • The vehicle felt unsafe to drive after Kia’s service. • Firestone’s diagnostic confirmed the alignment was significantly off. • Firestone corrected the alignment and the vehicle immediately drove normally. I am filing this complaint because the dealership returned my vehicle in a condition that affected its stability and safety, and the documentation from Firestone clearly supports this.

The first time I drove this car after getting screwed in my contract , I pulled over in a pullout spot to turn around. I went to back up and it would not move. I tried everything to get it to go. There was a ed malfunction warning on the dash panel.between 5 and 10 minutes later it finally backed up and then trying to go forward did the same thing. I called Kia in medford and took it in, Noone had heard of such a thing and basically just sent me on my way. This is a brand new car. It wasn't even 3 hours and this happened. It happened again. I wanted them to take the car back for this and the fact that my contract was nothing like we agreed to. I want to give it back, already recalls and they misrepresented what they did. There was no paperwork, they didn't find it important, although I was stuck in a pullout lane twice.

Took car in and dealership kept it. Recall indicated that parts were available, however, dealership says that because there's additional fraying of wires, they don't have the parts. When I contacted Kia corporate, they confirmed that they have release of parts indicated as "TBD." According to NHTSA records, they should have the parts but they say they don't and can't indicate when parts will be available.
