NHTSA lists 1 safety recall and 19 owner complaints for the 2019 Kia Niro. Most complaints involve electrical system (8) and power train (8). The EPA rates it 43–112 mpg combined.
Kia America, Inc. (Kia) is recalling certain 2017-2022 Niro and 2018-2022 Niro Plug-in Hybrid vehicles. Fluid may leak into the printed circuit board inside the hydraulic clutch actuator, which can result in an engine compartment fire.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“My 2019 Kia Niro EV, with approximately 75,000 miles, continuously displays a “Refill inverter coolant” warning. While driving, the vehicle intermittently displays the turtle-shaped reduced-power warning and experiences a significant loss of acceleration. The vehicle does not respond normally to accelerator input. The condition sometimes clears after a period of driving, but when traveling uphill, the warning and reduced acceleration persist. This creates a serious safety concern because the vehicle may be unable to maintain speed or accelerate sufficiently on hills or when merging into traffic. The vehicle has been at an authorized Kia dealership for approximately seven days. The dealership has not yet identified the cause and has reportedly contacted Kia corporate technical support. The dealer has also indicated that another vehicle has presented with a similar issue. I am requesting an investigation into the potential coolant-circulation or thermal-management defect and its relationship to unexpected propulsion-power reduction.”
“Our 2019 Kia Niro EV (approximately 138,000 miles) exhibits an abnormal rumble/growling noise from the front drive unit while driving slowly in "D" range and when accelerating or decelerating between 0–25 mph. This symptom matches exactly the condition described in Kia Technical Service Bulletin ELE234 (Rev. 1, April 2021): "Drive Unit Inspection & Replacement for EV Motor Rumble Noise," which covers all 2019MY Niro EV vehicles produced from December 5, 2018. To our knowledge, TSB ELE234 has never been performed on this vehicle. The repair involves replacement of motor/roll mount brackets and, if necessary, traction motor or reduction gear replacement. Kia has a documented, tiered repair procedure for this exact issue with assigned labor operation codes. The failure presents a safety concern because drivetrain noise at low speed can precede loss of drive power or sudden drivetrain failure, which creates a hazard in traffic, intersections, and during highway merging. Despite the existence of this TSB since April 2021, NHTSA appears to have few or no formal complaints logged for this specific defect, meaning it has not triggered the regulatory scrutiny it…”
“The contact owns a 2019 Kia Niro. The contact stated that upon starting the vehicle, the engine seized. The contact stated that the vehicle failed to shift into gear. The check regenerative braking system message was displayed. The vehicle was towed to the local dealer where it was diagnosed that the transition motor needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, and the contact was informed that the repair was not covered under warranty. The failure mileage was approximately 90,000.”
