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 s…

Owner report 11549802 · 2023-10-13 (October 13, 2023)
I backed out of my drive and began to go forward. Five times in my 2023 Kia Niro HEV within one block the dashboard began to flash red, beeping sounds were emitted, and then the brakes slammed rapidly bringing the car to a stop. My attempts to accelerate were futile until the car let me accelerate about 5 -10 seconds later.. There was absolutely nothing in front of me or to the sides of me or anything coming towards me. This was entirely phantom braking. In four of these phantom forward collision avoidance ( FCA) instances there was nothing…

Owner report 11536892 · 2023-08-07 (August 7, 2023)
Forward Collision System: When stopped or at low speeds, the vehicle’s forward collision warning will activate for short intervals (roughly 1-2 seconds) randomly. Hybrid Battery: The vehicle won’t go below 50% battery on the hybrid battery and the engine unnecessarily turns on to charge back to 90% when hitting 50% rather the exercising a wider range on the battery such as 20-80%

Owner report 11633950 · 2025-01-03 (January 3, 2025)
Each time I don't drive for a few days and start driving again, the car jerks/jolts as it's shifting gears (both when I'm accelerating and decelerating). The sudden jolts is dangerous as I'm gauging cars ahead and behind me as I'm driving. But when I brought it up to the service department, they said they can't diagnose it if it isn't happening at the moment, but by the time I've driven to a dealership, my car is warmed up and not jolting anymore.

Owner report 11597684 · 2024-06-29 (June 29, 2024)
Last year, I purchased a new 2023 Kia Niro Hybrid and had a 24-month lease contract on it. After 9 months (5,700 miles), my car started having problems (Forward Collision Warning, random loss of power steering). My car had to be towed twice to a KIA dealership, where I was told nothing was wrong with my car. They finally agreed to run a scan on the electric syste, where they found a few communication issues. After doing a system update, KIA told me the problems were fixed, however, the car kept having the same problems plus a new one (random …
