The contact owns a 2023 Kia Niro. The contact stated that while her husband was driving at 40 MPH, the vehicle hydroplaned and pulled to the left unexpectedly. The contact initially contacted the dealer and was informed of the headlamp replacement and general inspection. Additionally, while the contact's husband was driving, the driver-side front tire experienced a blowout near a service station; the technician advised that the tire exhibited steel tread. An independent mechanic attempted a wheel alignment but discovered a rusted, bent tie rod, preventing the service. Following dealer instructions, the vehicle was towed to the dealer, where the wheels, both hub bearings, tie rods, and brake calipers were replaced. Despite the repairs, the owner refused to reclaim the vehicle due to the recurring mechanical defects. The manufacturer was not notified of the failure. The failure mileage was approximately 71,000.

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 Automatic Emergency Braking). At this point, the car was too unreliable to drive so I returned it to my KIA dealership. Although the car clearly had problems that Kia couldn’t fix, I had to pay to get out of my lease and ended up buying another car, not a KIA. I am reporting the issues with the 2023 KIA Niro Hybrid to make sure people are aware of the issues on this particular car in case it is put on the pre owned market. I believe we’ve been very lucky not to get into an accident, my [XXX] drove it in the city and on the highway and I can't imagine what would have happened if the Automatic Emergency Braking would have gone off then.

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 verdict →
