NHTSA Complaint #11682404 — 2021 KIA K5

At the beginning at the year I had to change my starter because my car would leave me stranded on the street, at a stop light or any time my car would stop. I was once in the car with my little brother and in the middle of the street it would not start again and left us stranded. Others around me had to help me push the car to the side of the road that way I wouldn't be rear ended. Now, I'm having other issues such as HVAC were my cars AC does not turn on. It doesn't even blow hot air. Some mechanics have told me it's probably my blower and resistor and other that it's a wiring issue. My car is only 4 years old and should not be having so many issues. I have tried reaching out to Kia but always get sent to voicemail or have told I would be charged for it to just be seen. If anyone could help me with my car that would be greatly appreciated.
