Finally got car back from previous repairs and it was making a loud groaning noise all the time. Took it back to dealership and they said they had to repair the rack and pinion system and the gears were shredded. Employee says they now have another niro with the same problem as my original symptoms when transmission was replaced twice. Car has consistently had problems with the RPMs being incredibly high at low speeds but the dealership can't seem to replicate the problem. Car randomly switched over to manual mode after a long drive. Video of problems given to employee and just said he's going to give them to his field technician. Car has now been at the dealer for over 4 months and was finally returned because they can't reproduce the problem.
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.

What happened? While driving my 2025 KIA Niro on [redacted] , I stopped at a red light behind another vehicle. Suddenly, my car was rear-ended by another vehicle, causing a significant impact that pushed my car forward into the vehicle in front. The seat belts deployed but I sustained a broken nose from hitting the steering wheel. My daughter and I were taken to the hospital for treatment.

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). …
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.
The contact owns a 2022 Kia Niro. The contact stated that the rearview camera displayed a distorted image while the vehicle was in reverse(R). The failure obstructed the driver's visibility, preventing the driver from safely operating the vehicle. Additionally, there was a delay with the image appearing on the screen when the vehicle was in reverse(R). The vehicle was taken to the dealer, but it was unknown if the vehicle was repaired. The contact stated that on a separate occasion, the vehicle failed to start up, with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the battery terminals were loose. The vehicle was repaired; however, when the contact arrived to retrieve the vehicle, the vehicle failed to start. The dealer inspected the vehicle; however, no cause for the failure was found. …
This car was purchased certified pre-owned from a Kia Dealership with 46,227 miles in October 2024. Within a month (Nov 2024), the electrical system would die overnight and we would require a jump start. This seemed to align with colder temperatures. After the first or second jump start, a headlight blew out. We replaced it. Then a tail light blew out and we replaced that one too. It seemed that there must be a connection between the electrical failure and the headlights / tail lights burning out. We took it in for a software update to see if that solved it, we also had them check the hybrid battery and the 12V battery. No other issues were detected. Eventually the problem just stopped happening. Now in Nov 2025, a year later, the problem has returned. The car's electrical system dies overnight and we have to jump start the car. And another tail light / turn signal has burned out. …
