Presumably they know more about the root cause through looking at the logs. It would be so great if they could be more transparent about it. On the surface it doesn’t make sense that a FW issue would be causing an issue with your TM3. What about the other ~200,000 cars on the road? But to answer your last question, yes, it’s layers of incremental software functionality on the same hardware stack. Without knowing at which point it’s failing it’s hard to say if cruise could be enabled without AP. As a point of comparison, I had my TM3 wrapped in protective film. As part of that process they removed trim including the side cameras to lay the film flat with fewer cuts. The shop (not Tesla affiliated) left the side cameras disconnected. Upon starting the car it reported an issue with side cameras. AP worked but degraded — wouldn’t change lanes, and cruise still worked fine. Some some hardware faults do not fully disable the feature.

>left the cameras disconnected... AP worked but degraded That’s very interesting, and closer to what I would expect. The newest development, when I drove in this morning, the Service Tech said it’s a seatbelt sensor malfunction. There is a “driver seat buckled” interlock for cruise control, but the alert for that explains the reason. I’m just getting “cruise not available” with no explanation.

  Yeah I unbuckled once while AP was active to try to take off my coat and the car lost its shit on me. Red flashing alarms like, “WTF you doing?!” I think that service tech was grasping at straws, unless he actually examined the logs and saw it written there. If it was the seat belt, wouldn’t you see it indicated on the display that the seat belt was unbuckled? It displays the unbuckled indicator for all seats that have occupants detected (weight sensor). Presumably the logs will contain the exact reason it fails? Next time they text you maybe ask if they can tell you exactly what the log file says when AP engagement fails.
