2022 Kia Niro Complaints

Intermittent warning to "Refill Inverter Coolant" displays on the dash screen. This is a known issue pursuant to SA512 (ELE 270 Rev 3) due to faulty coolant that crystallizes and interferes with the sensor. However, per Kia, it is only covered under standard warranty (5 years/60k miles) and while my vehicle is within the year warranty, it is over the mileage. Quote was to replace "Chiller, water pump and flush coolant system" at a cost of $2369.02 including parts and labor. Dealership will not perform recommended maintenance of coolant flush (every 37k miles) without replacing these parts. If this was a known defect why is there a limitation to the SA? It should be covered as a recall, not a voluntary service alert. I am unable to properly monitor the in-dash warnings regarding coolant levels until this problem is fixed

The vehicle has a recurring P0420 code (“Catalyst System Efficiency Below Threshold Bank 1”). A boroscope inspection at Ricardo Caballero Kia Santa Isabel (invoice #[XXX] dated December 5, 2025) confirmed internal disintegration of the catalytic converter, with physical pieces of the catalyst falling out when the exhaust pipe was removed. This failure appears related to Recall 23V534 (SC276) and TSB PS709 (overheating / coolant boiling issues in 2017-2022 Niro Hybrid models). Motorambar, Inc. (official Kia distributor in Puerto Rico) has ignored my warranty claim since December 2 and December 22, 2025 (more than four months). Motorambar is now refusing to authorize a courtesy loaner vehicle at the dealer Ricardo Caballero Kia Santa Isabel, claiming the tests will take less than 5 days. This leaves me without transportation. The catalytic converter is fully covered under the Federal Emissions Warranty (8 years / 80,000 miles). I request that NHTSA investigate this as a potential safety...

The contact owns a 2022 Kia Niro. The contact stated that the rearview camera displayed a distorted image while the vehicle was in reverse(R). The failure obstructed the driver's visibility, preventing the driver from safely operating the vehicle. Additionally, there was a delay with the image appearing on the screen when the vehicle was in reverse(R). The vehicle was taken to the dealer, but it was unknown if the vehicle was repaired. The contact stated that on a separate occasion, the vehicle failed to start up, with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the battery terminals were loose. The vehicle was repaired; however, when the contact arrived to retrieve the vehicle, the vehicle failed to start. The dealer inspected the vehicle; however, no cause for the failure was found. The contact was informed by the dealer that the vehicle had an open recall, NHTSA Campaign Number: 25V426000 (BACK OVER PREVENTION). The ve...

Vehicle with code p0420, Kia dealership technician say: the problem was the spark, proceeded to change it and clear code. Check engine turn on again, the same person say: it’s a ring piston, the car was leaked engine oil to exhaust and he see blue smoke, no evidence for part of dealership and dealership never mention the car was consuming excessive engine oil. I mentioned the law of emission to change the catalyst and the boss say: I can’t change it but the problem will be come but never do anything to change it. In other dealership Kia the technician dismantle the exhaust and see ceramic part coming from the catalyst, his recommendation is change it. Dealership make a formal petition to motorambar distributor official ok Kia in PR and motorambar refuse to change the part with the evidence provide by dealership: technician report and photos. I call motorambar in 2 times and the only thing motorambar do is creating ticket to escalated to technician, never received call from this ticket,...

What component or system failed or malfunctioned, and is it available for inspection upon request? -I have received a "Check Brake Light" warning several times now, even after replacing the bulbs. I have replaced them twice now in the past 6 months and the issue persists. I believe it to be a faulty sensor or something similar. Yes, it is available to inspect upon request. How was your safety or the safety of others put at risk? I do not know if my brake light is functioning properly as this warning indicator comes on intermittently even though the light has been replaced and even when it seems there is nothing wrong with the light. It is very stressful. Has the problem been reproduced or confirmed by a dealer or independent service center? I took my car to the dealership in November 2025 and they couldn't find any issue. The indicator light did not come on at the dealership but came on again later in the week. They even replaced both brake lights hoping that would help. Has the veh...
