I am submitting a complaint regarding a safety issue with the rearview camera on my 2020 Kia Niro EV. VIN # [XXX] The rearview camera display has stopped functioning properly. Based on technical research and driver community reports, this issue appears to stem from an electrical surge that causes the camera circuit to malfunction. Upon checking owner forums, I became aware of an active manufacturer campaign/recall (Kia Recall SC342) related to this fault. However, I have not received any official recall notification or letter from Kia regarding my vehicle. Because a non-functioning rearview camera significantly reduces rear visibility and poses a clear safety hazard, I request that the…

I had just left my doctor after a protracted visit and was almost late for dinner guests. I noticed a thumping and thought it was the road, but it was a 3/8" bolt in my tire tread.I pulled up at Costco, hoping they could repair it quickly but was told I had to wait 2.5 hours when I had guests coming in an hour. I decided I would have to change the tire. When opening the trunk I found there is no spare, but saw a kit to fix the flat, which I vaguely remember reading about. I'm in a huge hurry to get home but I open the Owner's manual and there is: NADA about the flat repair. So I look at the components. There is a container of the repair solution and a pump with cartoons on it and a hose…

There is a silver strip that runs horizontally along the middle of the dashboard from one side to the other. Itâs made out of a very reflective material. During the midday hours, it brightly shines the sun directly into the driverâs and passengerâs eyesâitâs very blinding!âand makes it difficult and unsafe to drive. I canât even begin to think about teaching our teenage son how to drive in this car because of this safety issue.

About 7 months ago, "Refill Inverter Coolant" warning came up. Since then, I've scheduled service appoitment wtih Van Nuys Kia dealership 5 times to resolve this issue, but even after recent appoitment 2 weeks ago, this warning is still came up on my dashboard. Every time I start the car, the persistent refill inverter coolant light comes on. I believe I am experiencing this issue because KIA and their dealership where I bought my car doesn't want take ownership of this issue and resolve it. I am deeply concerned about my safety and the safety of my children when I drive my Kia vehicle.
