A complaint is an unverified account by the person who filed it, not a
finding of fault. One complaint is one ODI number, which is how NHTSA counts
them.
Complaints more than doubled year on year: 19 in the twelve months to 2026-Q2, against 8 in the twelve before.
A recall is the manufacturer conceding a defect, and the repair is free.
Whether one covers your particular car is a question only its VIN can
answer, because a campaign covers a production range rather than a
model year.

One complaint can name several systems, so these add up to more than 82.
When the complaints arrived
By the year NHTSA received them
By the year NHTSA received them, which is not the year the failures
happened. They peaked in 2026 at 21.
This is the year the complaint was filed, not the year the failure
happened. The range runs from 2017 to 2026, the last of them a part year, which is why its column is drawn faint.
Crash test ratings
NHTSA New Car Assessment Program
NHTSA has not crash tested the 2017 Kia Niro. Its New Car Assessment Program
tests a selection of each year's vehicles and does not reach
motorcycles, heavy trucks, motorhomes or most low-volume models, so
an absence here says nothing about how the vehicle would perform. It
is not a low score.
What owners have reported about this vehicle is below, and it is a
different question: a crash test measures what happens to the people
inside in a controlled impact, while a complaint records what broke
during ordinary use.

fire
On XXX, at approximately 11:30 a.m., a friend and I were driving on XXX near [XXX], when I noticed smoke coming from the engine compartment. As I pulled over to the side of the road, a warning light appeared on the dashboard. Once stopped, I saw flames coming from the engine compartment. We immediately got out of the car, retrieved our dogs from the back seat, and ran away from the burning car. Another motorist who had witnessed the flames pulled over behind us. Because our cell phones were still inside the car, we used his phone to call [XXX]. The Tennessee Highway Patrol and the Fire Department responded to the scene. The car was completely destroyed by the fire and was declared a total …

POWER TRAIN
The vehicle's hydraulic clutch actuator (HCA) has failed and is actively leaking fluid onto the printed circuit board (PCB), creating an immediate electrical short and engine bay fire hazard. This failure is identical to the defect detailed in Safety Recall SC276 (NHTSA Campaign 23V534). As indicated by a search of my VIN, the vehicle was brought in by us previously when we learned there was a recall, and the recall was officially marked "completed" in the NHTSA database. However, the dealership at the time claimed the vehicle was not affected by the recall, stating there was nothing wrong. They simply performed the minor step of changing a fuse to mark it as completed but did not provide …

ELECTRICAL SYSTEM
My 2017 Kia Niro has developed a serious hybrid system failure that causes the vehicle to shut off unexpectedly while driving. For about a month, the car would only start using the “12V Battery Reset” button. Now it starts, but after driving a short distance, the vehicle loses power and shuts off without warning. The only way to restart it is by pressing the reset button again. The AC and accessories continue to run, and the high‑voltage battery appears to charge normally, but the car cannot maintain 12V power under load. This is consistent with a DC‑DC converter or 12V subsystem failure, which is a known issue in early Kia Niro hybrids. This sudden shutdown creates a dangerous situation, …

ELECTRICAL SYSTEM
My 2017 Kia Niro exhibits a dangerous low-speed engine surging hazard matching Safety Recall SC276. An authorized Kia dealership technician inspected the vehicle under RO #6115244 and formally documented 'seeping fluid residue' inside the clutch actuator housing. However, the dealership and Kia Corporate are refusing to honor the recall remedy and have released the car at a $0.00 balance while explicitly stating in writing that the vehicle is 'not safe to drive.' I am requesting federal intervention for safety campaign non-compliance.

If this is your car and a dealer keeps failing to fix it, your state's
lemon law may require the manufacturer to replace it or buy it back. How
many repair attempts it takes, and how long you have to file, is set by
the state you bought in and by nothing on this page.
