EngineCrash
I have experienced two incidents of sudden, severely reduced propulsion while driving my 2024 Kia Niro Hybrid. The incidents occurred several weeks apart. During both incidents, pressing the accelerator did not produce normal acceleration. The vehicle continued moving with very limited propulsion, but the gasoline engine remained at 0 RPM and did not engage when additional power was requested. There were no warning lights, error messages, or other indications of a malfunction on the dashboard. During both incidents, I shifted to Neutral and back to Drive while safely coasting, but this did not correct the problem. After coming to a safe stop, placing the vehicle in Park, turning it…
Sep 28, 2026Forward collision avoidance › Automatic emergency braking
My 2024 Kia Niro Hybrid has experienced multiple issues that I believe should be documented. The vehicle previously displayed an Electronic Parking Brake (EPB) warning. It was taken to an authorized Kia dealership for diagnosis and repair. Although repairs were performed for the EPB-related issue, I am submitting this report so the condition is documented if similar reports are being received from other owners. In addition, the vehicle developed a persistent creaking/clicking noise during forward driving. The noise was not present when the vehicle was new and began after normal use. It is most noticeable during forward driving and is not heard while backing up. The vehicle has been…
Jun 1, 2025Forward collision avoidance › Adaptive cruise control
I was travelling on a road today and was in the right hand lane with adaptive cruise control on. I then switched lanes to the left hand lane (it's only 2 lanes) and the adaptive cruise control was still on. I noticed the car travelling faster than it should be for there being a stopped vehicle ahead. I was prepared to stop on the brakes and luckily I was! The collision warning came on and I immediately applied the brakes. How is it that the collision warning came on before adaptive cruise control came on? This is at least the 3rd time something like this has happened.

The interior surface of the windshield freezes during cold weather operation, beginning at the edges of the windshield and progressing toward the center directly into the driverâs line of sight. This significantly impairs visibility and requires approximately 20â30 minutes of vehicle warming before safe operation is possible. The condition has occurred repeatedly since November under normal winter temperatures. No warning lights or system messages appear prior to the event. The vehicle has fewer than 8,000 miles. The vehicle has been inspected multiple times by authorized dealerships. Three separate dealerships performed diagnostics and preventative service, including cleaning A/C…
Nov 30, 2025Electrical system
The 12-volt battery system in my 2024 Kia Niro (VIN: [XXX] ) has suffered two total failures in under one year of ownership (approx. 10,000 miles). In both instances, the vehicle was completely unresponsive, with no power to essential systems. Safety Risks and Incidents: 1. [XXX]: Vehicle experienced a total power loss. It would not start and all electrical systems were dead. 2. [XXX]: Identical failure. These failures create a significant safety risk by potentially stranding the driver in hazardous locations and disabling critical safety systems, including hazard lights, power steering assist, and emergency braking. If a total power loss occurs while the vehicle is in motion, it could…

Forward collision system fully activated while driving eastbound in the fast lane on [XXX] . The sun was behind me. No glare. No cars or objects were in front of me or next to me. The dashboard started flashing and warning sounds activated and the car slammed on the brakes itself. The seatbelt locked up and left me bruised. Miraculously, the cars behind me avoided crashing into me while I accelerated out of it. I could have been killed. Dealership minimized my concerns. I donât want to drive this car ever again unless someone can make sure it doesnât happen again. This safety feature malfunctioning is a death trap.
