In the middle of driving, these warnings came on
Pulled over to check brake lights and turn signal in the back, they are fine. Not sure why, I will be doing more testing at night.
Although warnings are bad and upsetting, but I'm very pleased with the detailed warning message and clear indication. My old vehicles would just hyper flash in this case

update:
The brake/rear turn bulbs were tested last night, no problem at all in park or drive situation and over multiple engine on-off cycles.
Today during the day, can't reproduce the same warning.
speculation:
I think this might be heat related, during the time the warning persisted, ambient temperature reached near 100 degrees, and the rear end had been basking under the sun for a while, especially the left rear pointing towards the sun.
The heat potentially triggered some sensor malfunction.
And interestingly, we're in a chip shortage crisis, and OEMs are buying whatever they can find, so perhaps chips that aren't made with the exacting standards of temp range are allowed in none mission critical parts.
