I'm chasing a problem we have with Track Mode in the Model 3 but it only affects Intel Atom-based models. Ryzen works OK.I believe it's not just MCU1 cars affected. Model 3 and Y are too. In any case, I'd probably just buy a cheap mobile hotspot and put a Lebara SIM in it before I'd consider spending £1400 on the MCU2 upgrade. At the moment I just always put my mobile in hotspot mode when I get in the car. I never get through all 15GB of data on my contract anyway.
When I spoke to them about they suggested there may be a link between that and the connectivity issue. I'm not convinced of that myself, but there's a possibility.
So just because it's a M3/MY doesn't mean it's not related to the MCU/GPU.
Has anyone compiled a list of affected owners with details of the model of car & GPU affected and locations/timestamps where it happened?
Sometimes you just have to do some of the work for them if you want something fixed...
