On Wednesday, we drove ~47 miles to the far northwest tip of our island. Even though the sun was at our back, ACC shut down more in one day than it has in total since we bought our car in November, 2014. ACC also failed to recognize a large white box truck in front and was accelerating toward the back of it until I intervened by pressing the brake pedal. The ACC icon did not show a vehicle in front, so it definitely was clueless about this truck. This had never happened previously. Such software glitches make me wonder how well autonomous driving will work. As a retired software engineer, I know the difficulty in eliminating all software bugs.
However, on the return trip in mid afternoon, ACC didn't shut down once. If anything, the windshield was likely a bit dirtier with a salt layer having parked near the ocean for several hours. Weird! But the November update did dial back the regen immediately when the ACC shuts down making this experience a much less jarring event which is nice.
When we departed on our return trip, I noticed that the nav screen was displaying the screen that it displays when the car is shut down. No iDrive button press would change this screen. It was like iDrive was hung at the car shutoff screen. I wanted to use the nav, so I had to pull over, shut down the car, and start it back up so that the nav screen displayed the usual startup screens. This has never happened before the November update which might or might not be responsible.
