Remote start Stinger 2022

Hello, I figured it’s worth a try to post this. Appreciate any suggestions.

My 2022 Stinger GT1 (leased) remote start stopped working about a year ago. It’s been serviced shortly after for about a month, and after many attempts to try and fix it they were never able to figure it out.

I recently took it to a different location for service, left it there for about a week and they were also clueless about what is happening.

Any ideas on what I should do in this situation?
