KIA NIRO 2023 UNKNOWN OR OTHER
mediumThere's a problem with the horn in my car. Either the high or low. The problem is intermittent and the horn will fail and it is not available in emergency situations. I brought this to the dealership and made them aware but they refuse to take this seriously and two adequately evaluate the car. They blew the horn and said it was working. It was not working and I said it was intermittent and they said well we could not find any problem. There were no warning lights. Nothing else. The horn is just intermittently failing.

KIA NIRO 2023 VEHICLE SPEED CONTROL
mediumThe contact owns a 2023 Kia Niro. The contact stated that while driving at 25 MPH, the vehicle independently accelerated. The contact constantly depressed the brake pedal to stop the vehicle. The contact was able to coast the vehicle to the residence while depressing the brake pedal to prevent the unintended acceleration. Neither a dealer nor an independent mechanic was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 11,000.
KIA NIRO 2023 WHEELS:HUB
mediumThe 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.
KIA NIRO EV 2023 FUEL/PROPULSION SYSTEM
mediumThe vehicle is a rental vehicle. It experienced two incidents of sudden loss of propulsion within the first two days of operation. During both events, the vehicle became completely unresponsive to accelerator pedal input and would not move despite being placed in Drive. I attempted to shift the vehicle into Park and then back into Drive, but propulsion was not restored. No warning lights, malfunction indicators, or system messages were displayed before or during the failure. The first incident occurred while exiting a car wash. The vehicle became immobilized in an active traffic lane and would not respond to throttle input, creating an immediate risk of rear-end collision. Vehicles were approaching from behind and I narrowly avoided being struck. The second incident occurred later the same day in a parking lot while the vehicle was charging. Again, the vehicle became unresponsive without warning and would not move. The intermittent and unpredictable loss of motive power presents a serious safety hazard because it prevents the driver from maintaining control and safely operating the vehicle in traffic conditions.
