I pulled the vehicle out of my garage yesterday and drove it out and turned it around and put it in reverse to park it on a very slight incline on my driveway close to the garage to clean it, put it in park, and shut if off. I spent a couple hours vacuuming and cleaning it. I then went to turn it on to back it into my garage for the night and it lurched backwards in an alarming scary way - I rolled my passenger window down and asked my husband who was right there if there was something in the way that I had just tried to run over with my car. He assured me there was nothing in the way so I put the car in drive and tried to go forward and it did the same thing. It was like I was trying to go over a log or something. (My husband said the same thing had happened to him when he also had it parked on the slight incline and he said to shut it off and try again). I then shut it off, put it in drive and as soon as I took my foot off the brake it flew forward without me ever touching the gas peddle. I slammed on the brakes and it stopped. It was like the cruise control was set to 60mph and it was accelerating without me in control. I tried another time to get it to operate correctly and the next time the rear wheels locked and it flew forward with the wheels locked, leaving a skid mark on my driveway. My husband then took over trying to figure it out and had the same things happen to him. We left it parked outside in our yard and called Kia. It was towed to Berlin City Kia in Williston VT today. This was all recorded on my ring camera. It also did it when the tow truck driver came. He said "I've been doing this for 23 years and I've never had an experience like this".

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2023 Kia Niro EV verdict →
