Bad Throttle Acuator

Hello, I was hoping someone could give me some advice if they have it. I have a 2022 rocket 3 gt. I just got confirmation from my mechanic that it has a bad throttle actuator. Which apparently the only way to fix it is to buy a whole throttle body assembly. The whole thing is at least $3800 in parts. I’m going to reach out to warranty to see if they cover it but don’t think they will. Does anyone have any advice or similar experience?
