I previously had major issues and recall 23V534000 fixed on my 2017 Kia Niro. I had issues again and took it to the local Kia dealership in Wichita, KS. They found a leak in a seal causing fluid to leak on to the clutch actuator. The service tech indicated it is related to the recall. I have spoken with Kia customer service escalations on multiple occasions. Originally they stated it was related to the recall. When I spoke when them today, on the phone they said all the parts that are affected are what were changed out previously. When they called back, they changed the story and said it is not related and they would not pay for it to be fixed, even though they previously said it was the exact thing related to the recall. When I emailed and asked for it in writing as to why it was denied, she changed the reasoning. It was nothing the same that she had told me on the phone. This is a safety issue that should be fixed by the manufacturer and they are refusing to fix it and telling me I have to pay over $5000 to fix it. Completely unacceptable.

Hybrid System Failure due to overheating Overheating due to coolant leak into resorvoir My car started having white smoke come from exhaust during driving Took to the repair shop, repaired the coolant reservoir next day, same issue took back to the service tech stated they couldn't find the leak, but the reservoir was empty. Took the car for a second opinion, the service people had my car all day, after picking up, was told by the repairman that it was the engine and KIA is aware of it. Stated he is unable to help and I should take the car to a KIA dealer For weeks the car was still blowing smoke Took the car to KIA of Stamford Had the car for a few hours, tech said coolant leak and I will need to replace the part which is 3000, advised there is a bypass method on the internet for NIRO owners with the same issue online, and I was told they will not do the bypass due to emission laws. Advised my car should be covered under Emissions warranty, and was told it does not cover the part. Advised the service man this should be covered under my 100,000 warranty with KIA, which is what I was sold, and was told this is not the case, and I wasn't covered. Advised KIA I have an extended warranty with WIZ autos where i purchased the car. Spoke to the warranty department and was told it wasn't covered under their warranty either. May 2023 While driving I saw white smoke, my car began to overheat and I tried to pull over, when I pulled over the car would not drive. HYBRID System Malfunction The car has been with Wiz autos and they are now telling me the repairs will cost $5,800 There are many people online suffering because of this defect. There are reports online that once fixed, the issue returns months later. Wiz autos is asking me to pay 6000 for a repair and 3 month warranty on the part. Issue: Coolant leak is causing issues that affect the safety of drivers, as well as destroys their vehicles and KIA Motors has been the worst to work with.
WHILE PARKED AND ENGINE OFF, THE TRANSMISSION SLIPPED OUT OF PARK AND ROLLED BACK INTO ANOTHER VEHICLE. NO ONE WAS IN THE VEHICLE AT THE TIME. WHEN I RETURNED TO THE VEHICLE, IT WAS STILL SHOWING IT IN PARK AND OFF.
