Consumer Description

Computer will suddenly error out and cruise control, AEB, forward collision warnings, and lane keep assist are not available. A warning "cruise control unavailable" shows if you attempt to engage autopilot or FSD. No forward collision warnings, no auto slowing down. Not docked for close following. No visualizations made. Not resolved with soft or hard reboot. Sometimes will randomly will allow to re-engage, other times I have to park the car and let it go to sleep without charging or sentry mode for things to reset. I've driven many, multiple times including for 1.5-2hour segments with a frozen visualization and no AEB or cruise control or FSD. Speed independent, weather independent. Time of day independent.
