AP3 and wipers have a mind of their own... sometimes. I don't think it's related.
It’s not the AP3 that’s causing the problem. It’s the camera sensors and the software that’s running the wipers subroutine.
This is separate topic - I think there are issues with the hardware and software stack in general on the 3 and Y. Sometimes, the event triggers are just not recognized in time. Since I will be interacting with the Tesla hardware team shortly, I am planning to bring this up to one of the senior execs who I know well.
1. Homelink doesn’t work reliably.
2. Auto fold mirrors don’t unfold in time consistently when pulling out of the garage.
3. Navigation is sometimes too late to inform of upcoming turns, or places the car in a completely different location (the latter could be just the GPS signal loss issue)
4. User profile is not recognized reliably when entering the car. Sometimes it works, but more often than not, it does not work. The seats, mirrors stay in the previous profile most of the time.
5. The side camera video feeds take a long time to become visible when backing out of the garage (when they would be needed the most). They are black and showing a turning ring until after you’ve pulled out. Then they become available.
Most of these issues are related to how fast the CPU is managing its various tasks and subroutines, which in turn is related to the software stack prioritizing its work. Some could also be related to sensor warm up time, and things related to boot up times.
Taken together, one or two things in the above list show up 1-2 days of the week.
