So here's the resolution.
Subaru claims that because the problem is with the software that operates the head unit, it is not covered by warranty, only the hardware. But out of the kindness of their hearts they decided to cover updating the software to my head unit free of charge. As it was explained to me, if they did a poor soldering job and that caused your head unit being broken that is covered by warranty. If they did a poor programming job and that has caused your head unit to be broken that is not covered by warranty.
But in a twist, they say I'm not supposed to have the Starlink services so they took them away from me. Even though they are not required to comply with the law until June 1st, they decided that any MY 2022 or later vehicle cannot have starlink in MA. I agree with him that the law, as written, is vague and unpractical, but SoA's response is to take their ball and go home. The only problem is that the functionality was part of the sale and not excluded or disclaimed at the time of the sale. I don't know if that's the dealer's fault or Subaru of America, but now that I have less car than what I paid for I will let them squabble over whose fault it is.
