Headlights Turn Off While Driving Problems of Toyota Highlander

Early today, 3/21/19, was alerted that my hatchback was open. The car had been locked for several hours, but when I came outside I was told by a friend that the hatch had just opened on it's own. About an hour later, I was driving after dark and received a blindside mirror alert--the closest car was at least two car lengths immediately behind me in the same lane. Shortly after, the caution light came on, beeped, the eco light came on, it beeped again and the eco light went off. About 40 minutes later, I had the bright headlights on with the auto dim enacted. The headlights went out, the dash lights went out, the radio stayed on, and the navigation screen got very bright. I had to return the light control on the signal switch away from the setting and then back to get the headlights and dash light to come back on. All events except hatch were when vehicle in motion. Hatch opened while parked and empty. All events were within approximately 2 hours of each other. 10000 mile service had just been completed 3/15/19 with no concerns noted.

The complaint has to do with computer systems on this vehicle. Some of the complaint is convenience, but worrisome because other systems seem to be involved as well. The computer screen has always been slow/hesitent, with various "glitches". Vehicle has gps mapping screen which occassionally "disconnects" and resets to blank screen. The bluetooth and other systems have also "disconnected" and couldn't be reset until the vehicle was stopped and turned off. The headlights sometimes do not shut off, day/night doesn't work properly. Have had occassional problems with door locks not working as they should. Never know when and which systems will be affected. I have also filed a complaint about intermitent non-acceleration issues, which maybe related.
