Here's how screwed up it is for me:
2015 (bought new) = No active OnStar plan being paid for, but can use app's key fob functions, can send directions to in dash nav, get monthly reports. Website says I have The Basic Plan until 2020 (5 years since purchase)
2016 (bought used in 2019) = Safety and Security Plan active and being paid for. Can NOT use the key fob features, cannot send directions to in dash nav, do get monthly reports. Website says besides Safety & Security, says I have Basic Plan through late 2020 (1.5 years since purchase? weird), and Connected Access through 2024 (5 years since purchase)
2018 (bought new) = No active OnStar plan being paid for, but can use app's key fob functions, can send directions to in dash nav, do NOT get monthly reports. Website says I have The Basic Plan until 2023 (5 years since purchase)
What kills me is that I can pay $$ for the safety & security package but not get key fob actions on app, but on the 2 cars I am paying nothing on, app functions are active. Seems like inconsistencies on their part. I would call but fear there is something goofed on the 2015 and 2018 status and they would figure that out and shut off the active functions.
