NHTSA lists 4 safety recalls and 59 owner complaints for the 2023 Kia Niro. Most complaints involve electrical system (22) and forward collision avoidance (9). The EPA rates it 49–113 mpg combined, and NHTSA gives it 5 stars overall.
Kia America, Inc. (Kia) is recalling certain 2023-2025 Niro EV, Plug-in Hybrid (PHEV), and Hybrid vehicles. The floor wiring assembly beneath the front passenger seat may become damaged, which can prevent the front air bags and seat belts from deploying properly or cause an unintended side curtain air bag deployment.
Kia America, Inc. (Kia) is recalling certain 2023 Niro EV and 2024 EV9 vehicles. The differential gear bolts in the gear drive unit may not be tightened properly, which can result in a loss of drive power or cause the differential to lock up.
Kia America, Inc. (Kia) is recalling certain 2023-2024 Niro EV and 2023 EV6 vehicles. One of the drive shafts may have been improperly heat-treated, allowing it to break under load and resulting in a loss of drive power.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“My 2023 Kia Niro Hybrid has a recurring intermittent electrical defect. Warnings appear together: Check Hybrid System, Check Engine, Forward Collision, Rear Cross-Traffic, Lane Keeping, Driver Attention, ESC, Brake, Auto Hold. They appear and persist while driving, during which stability control, automatic emergency braking, lane keeping, and related safety assists are disabled. Once, the vehicle would not start and was temporarily disabled, recovering after several minutes. This creates risk from loss of all electronic safety assists in traffic and from the vehicle failing to start when needed. Stored codes show lost CAN communication among multiple modules: U0101, C1611, C1693, U0111, U0164, U0293, U042B, U1341. Confirmed by two Kia dealerships over five warranty visits. V1–2 (Coughlin Kia, Dublin OH): software updates; warnings returned. V3 (Ricart Kia, Columbus OH): inspected, released OK; warnings returned. V4 (Ricart): Kia Techline case [XXX] opened; CAN signal confirmed out of spec at a passenger kick panel connector; dash harness replaced per Techline under warranty (2,800). V5 (current): same warnings returned within days, confirmed by the dealership;…”
“Driving VA Interstate 64. Traveling right side travel lane approximately 70 mph. Had ADAS engaged. Car entering highway, moved to center travel lane to pass. As I approached entering highway car, suddenly, my car stalled, engine off and I was stopped in center travel lane. Able to start car by putting transmission in park and pressing start button. Called KIA Car Care Center - They have no record of this type situation occurring throughout country. Took car to dealer. Their Technology Service Rep checked whole system and found no problems including memory bank listing the stall/stoppage incident. I will go to dealer and ask for their report. 2nd incident. Happened within first month or ownership 10/23. I dismissed incident as something I must have done due to my lack of familiarity with new technology.”
“The 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.”
