Took delivery of a Model 3 in March 2019 and got FSD shortly thereafter. Entering and exiting the highway with Navigate on Autopilot (NOA) was pretty routine and no major issues.
However, over the last couple of months, merging onto the highway or merging into an exit lane from the highway is a bit aggressive.
Below is a crude sketch of a normal exit lane in my area (Midwest). When using NOA (Software version 2019.40.2.1) and merging onto the exit lane, the car always goes over the line and onto the shoulder or barely stays in the exit lane. The change is also very rapid, so much so that half the time I take over because something feels wrong.

The same issue happens when merging onto the highway, but the car nearly goes or does go into the middle (3 lane highway) or left (2 lane highway) lane instead of merging into the right most lane. The change is also rapid, such as the exiting described above.
- Cleaned all sensors and cameras
- Rebooted car (soft)
- Used manual lane change when using Autopilot to attempt to replicate. Autopilot performs maneuver correctly.
- Issue replicated in both good and poor weather conditions (i.e. sunny and clear as well as rainy and dark)
Has anyone else had or known someone with this issue and been able to resolve it?
