Coming down the highway after a 3 hour trip, gauges and dash lights start going on and off, windows don't work, crazy things start happening, but car is still running fine, pull over, shut car, re-start, car starts no issues, get home, turn car off, nothing works, no lights, won't start and key won't come out of the dash. Maybe some kind of anti theft , I'm stumped, car is completely dead now. 65,000 trouble free miles, now this.

 

Jump started it, fired right up, opened up battery box all looks good, charged battery and it took it, shows 14.1 volts charging good. The only code it shows after clearing is steering column alignment ? I'm stumped as to why it died while driving 3 hrs. on the highway, even if the battery was a little down 14.1 should have kept it charged ?
