Same issue with wipers. Were working fine and suddenly stopped working while highway driving. Wouldn’t trigger despite completely covered, had to do it manually. Like if it had hanged.
Other observation, when the HD maps were first rolled out, the speed limit would display exactLy when driving next to the panel. It was hugely precise. In recent updates, not so much. Nothing huge (not 50m), but enough to wonder if something has changed.
I was also stuck in traffic on the highway and the car was behaving like a drunk at very low speed, like if it was constantly trying to re-center. Had to eventually stop AP as other drivers probably thought I was drunk or trying to be funny. But in a not funny way.
Last, as other mentioned, the change lane takes a bit more time. A couple of times, I ended up stopping my blinkers too early for that new timing and my car violently swayed back on my original lane. Drunk-style again. I always hated that behavior: if you initiated, finish it, don’t use the blinkers as a command with arbitrary switching point.
