5/5 Overall
NHTSA 5-Star Safety Rating
For the 2023 Kia Niro, the two most-reported complaint areas are the electrical system and forward collision avoidance, with powertrain rounding out the top three. On the electrical side, owners describe a range of issues including complete loss of power while driving, warning lights illuminating unexpectedly, and the rearview camera cutting out or displaying intermittently, in some cases after over-the-air software updates. A handful of owners report the vehicle becoming fully unresponsive and requiring a key-cycle restart to restore operation. Forward collision avoidance complaints center on the system activating unexpectedly or behaving erratically during normal driving. Powertrain reports include sudden loss of propulsion where the vehicle won't respond to accelerator input despite being in Drive, and at least one owner describes an unintended acceleration event at low speed. A separate, smaller cluster of reports involves the electronic parking brake failing to engage unless the auto-hold feature is active first.

By System
The 2023 Kia Niro has 5 recalls, the most serious involving wiring beneath the front passenger seat that can be damaged when the seat moves, potentially disabling airbags and seatbelt pretensioners in a crash or causing an unintended side curtain airbag to deploy.
On the drivetrain side, recalls only affect EV models: differential gear bolts that are not properly tightened can cause a sudden loss of drive power or lock the differential, and a drive shaft can fracture under load and also cut power without warning. Both failures raise the risk of a crash. There is also an electrical concern on vehicles equipped with a 4.2-inch digital instrument cluster: the display can go completely blank at startup, hiding tire pressure readings, warning lights, and other critical information the driver would normally see.
