Go to your dealer and have them verify the CSP about the transmission and see if it applies to your Sport.
Your fluid definitely needs to be changed at that mileage which could be part of the problem.
I always had the screen warning of phone misalignment on my 2021 BL. The phone would always shift while driving. A ryal PITA.
On my 2025 BL never once have I seen that message. Works every time. I like the feature along with the wireless Carplay on startup.
Keep it on the vehicle but default to the off position. If I want to turn it on I will.
As Garth said, it really can't be good for the engine and the starter. JMO.
