UNHAPPY AND FRUSTRATED!!

I bought a Atos Motion 2022 model in 2022, brand new and it was cash purchase. late last year I started having issues with the fuel sensor and car seats. The seats have been replaced 3 times, but my main issue is the fuel sensor, it too has been replaced 3 times and in a matter of 8 months and it is still giving problems after it was replaced last month. No one seems interested in sorting out the problem. Hyundai just keeps replacing it seeing that it is still under warranty. I don't know much about cars, but logic tells me it's not the fuel sensor but something else. Every time the car must be booked it, which is 6 times now already, then I am without a car. I called Hyundai Boksburg left a message for the dealership principal to call me back, no one calls as well as the service manager. I then called the call center, which is no help, they told me to take the car to the closest dealership, I asked for a manager to call me back and nothing. Hyundai is quick to take your money, but their service is shocking to say the least. I'm currently driving the car and not sure how much fuel I have left because the sensor is once again malfunctioning. I could be standing on the side of the road and then what. I am a single parent and cannot afford to get stuck or be without a reliable car. I asked the service manager I want another car because this one isn't reliable to which I got no reply. He did say the fuel sensor should last a lifetime so now I'm on my 3rf life already in only 2 yrs.
