Owner report 11450471 · 2022-02-04 (February 4, 2022)
I was involved in a collision 11/2021. I had just left a stop sign and was starting to go when a semi hit my front end and spun my vehicle around. I do not understand why my air bags did not deploy and I feel like emergency braking did not work. I have had it work when someone get close to my bumper in the past.

Owner report 11455280 · 2022-03-04 (March 4, 2022)
I've had my Kia Niro EV approximately 1yr. I'm the only owner so far was brand new but it had set for a year or so. (Purchase Date: March 2021). I noticed about 6 mo./8k miles that listening the same thing that my 2012 Kia Sorento that was involved in the class action lawsuit was having. When I pressed the gas pedal my RPMs go up to five to seven but the car doesn't really go it's like it's barely even going 10 miles an hour. This to me is a huge safety concern considering what if you were trying to get out of the way of a semi and you have th…

Owner report 11485034 · 2022-09-18 (September 18, 2022)
My Niro has been having issues with sputtering, jerking, chugging, and feeling like it’s about to stall. Sometimes it happens right when I start the car and sometimes it happens while I am driving. The check engine light just started coming on yesterday. I believe the transmission is faulty and have spoken to or taken it to the dealer with this same issue multiple times as it is covered under warranty. They keep telling me that’s just how the car drives but in the 8 cars I’ve owned in my life, I have never had a car that behaves this way before…

Owner report 11719210 · 2026-02-19 (February 19, 2026)
When I’m braking at slow speeds, 10mph or less the front left tire braking system locks and makes the car skid. This happens randomly. There’s also a clicking sound made from the regen braking to switching to regular braking. The mechanic replaced the hca assembly and wiring kit from a recall but the car is still having the same issues. This also brings up the codes EBS and AUTO HOLD on my dash.

Owner report 11727309 · 2026-03-26 (March 26, 2026)
I own a 2020 Kia Niro PHEV. In October 2024, my dealership performed Technical Service Bulletin SA512 on my vehicle addressing the inverter coolant system. I was not informed at that time that the issue was likely to recur or that periodic maintenance would be required. In March 2026, the inverter coolant warning light returned. I brought the vehicle back to the dealership, where I was told the coolant had crystallized. The dealer confirmed this is a known recurring issue with this vehicle and stated it would need to be flushed approximately ev…
