Excellent information, especially about the deep sleep solution temporary fix. That could be useful in a pinch to get to safety. The question then becomes if this was an isolated failure, or if their have been multiplate instances. I suppose if it was the latter, they'd determine if the fault can be tied to a specific batch of controllers, and if so, proactively reach out to affected parties. Otherwise, if it's an isolated failure, not associated to a broader production issue with a specific batch, then it is what it is.
I don't envy the job of vehicle manufacturers. Thousands of hardware components, the failure of which can lead to a non-drivable vehicle.
Interestingly, one course of action could be a software change which recognizes the fault and rather than leaving the vehicle dead in its tracks, proactively triggers a reboot (or whatever sequence would replicate the wake-up from deep sleep), allowing the potential for a better temporary outcome than being stuck at an intersection. Until such time, though, it's good to keep that tip in your back pocket.
Great to hear about the level of service, too, but sorry to hear about your ticket, let us know how that plays out!
