Hyundai is dissapointing

In 2019 I bought a Hyundai i10 Grand Glide with much pride and excitement . The excitement was however, was short lived because the cars clutch started hardening a year later. Ive been to two Hyundai dealerships. They all say there is nothing wrong. It has gotten to the point where I need to book an appointment with the doctor because it's really hurting my foot. I am due for a service soon and I'm so anxious because I'm tired of being **** to by the technicians. I was hoping I could trade-in my Hyundai at a later stage for another Hyundai. But I'm tired of the lies.
