Update: So I contacted Tesla Service and they assumed it was a corrupted software update. They re-pushed the update to my MX to see if that would resolve the issue. Unfortunately, it didn't. If anything, it got worse. Good news is that within a week, a software update for FSD Beta v11.4.2 came out and I updated it. It fixed it!
However, now my FSD is almost useless now. It's trying to constantly lane hop, even when approaching an upcoming turn. For example, if I have an upcoming left turn and I am on a 2-lane road, it will change lanes to the right hand lane within a quarter mile of the left turn. Additionally, it's constantly trying to make left turns on a straight route (even though the navigation on FSD is showing the correct route). The route has me going straight for several miles, but it keeps trying to turn left into 'no through-street' neighborhoods. I even turned on "Minimal Lane Changes", but that did not make a difference. I've driven this same route to work on FSD for months with very few issues, but since the FSD 11.4.2 update, it's essentially unusable. The blinker comes on every 10-15 seconds and I have to cancel it. It's super distracting and I probably look like a nutbag to other drivers on the road.
I'm going to email FSD Beta about these issues to make them aware of it.
