People definitely complained about the random reboots, especially on the Nexus 6P, since that phone wouldn't boot again until after it was connected a charger plugged into a power outlet.
Heaven forbid you had a medical emergency away from a power outlet with a phone that unreliable.
Google just refused to do anything about it.
It soft bricked itself until you were able to plug it back into a power outlet.
Until then it was useless.
