New issues with 12.1.2 for me. Two incidents of lost TACC and Autosteer. Was driving on Autopilot like normal when I got the "take over immediately" warning. After that I noticed that TACC, and of course Autosteer, was not available. At the same time I noticed that my automatic headlights came on even though it was the middle of the day. Auto high-beams were not available (gray headlight icon with A inside was not on screen). After about two minutes TACC, Autosteer, & auto high-beams came back, and the headlights turned off. It's almost like a few software modules restarted. Today started having intermittent loss of low-end during Slacker streaming. There would be a slight pop, and loss of bass for about five seconds before it would come back. It was isolated to a single song, so maybe could have been a problem with the stream.
