“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. …”

“I first bought the car brand new from the car dealership and the first problem was a check engine light came on when I bought it. I took it to the car dealership and could not find the problem. I bought the car in December 2020. And off and on the check engine light comes and goes. And they could not find the error. Lastly about two weeks before the car caught on fire. It was service for oil change and a catalytic converter replacement. …”

“My key fob works perfectly fine. I came out from work and my car was dead, I pressed my key fob to unlock and nothing happened. I tried the key attached to the key fob and it’s strange because it doesn’t even fit to open the door. It was so hot outside because I’m in Texas and when I called KIA roadside assistance an hour passed by and they still hadn’t arrived. I could’ve had a heat injury, but I was able to hide under a tree for some shade. This is the second time my car just dies and doesn’t turn on without having to get help from roadside assistance. …”

“My vehicle was the victim of attempted theft and reported to City of Cincinnati police 8/11/23. It then underwent repairs and delays before it was returned to me on 9/22/23. The left side rear door is basically detached from the system, causing the alarm to go off or not even work. The back seat lock is completely malfunctional, and there is glass remaining inside the car. I was informed by two separate Kia locations that they would contact me about repairs. On 9/29, notice attached here, I was informed that when a remedy is available, they will repair and cover the costs. …”

“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. …”
