2023 Kia Niro PHEV Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Unknown which component exactly as it does not throw a fault. I believe it to be transmission related as the behavior seems like a clutch to me, but dealership has not been able to confirm. Vehicle rolls freely in directions other than what is selected and does not respond to throttle input. Described the issue to dealer numerous times and they claim to have seen it. I do not believe they actually have. It is currently at the dealer for the fourth time about the issue. Currently claiming engine issues but the engine isnt even on when it experiences the problem. (PHEV) Has been occurring since purchase but very intermittent. Could not reproduce until enough trial and error when it did occur that I could reliably reproduce it. During my own testing and diagnostic is how I found it can roll freely in the wrong directions and is much more dangerous than just shaking was. Description: Within the first few minutes of the vehicle being turned on it can shudder against the brakes when stopped. It can stop responding to throttle inputs and roll freely in directions other than the selected gear while throttle input is ignored. It will start responding again after some time, I dont know what makes it start responding again. Does not show errors or messages. Reproduce: Plug in car, let it charge all the way to 100%. Unplug and immediately start car, move forward or backward a few feet at a time. Shaking against brakes will start, and at that time if you let off brakes and attempt to move car it can shake loose of clutch and roll freely. It does happen outside of this specific scenario and I have recording of such, but most of my recordings are in this scenario as it is difficult to catch such an intermittent issue Some recordings at: [XXX] More detailed here: [XXX] And many more stored locally because they're very large, available if desired.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
