if you ever worked on automotive you know it's bs.
since CAN all reliability and predictive nature was out. we now have redundancy everywhere with everything just rebooting all the time.
install an aftermarket radio and your ecu will probably reboot every time you press play or something. and that's just "normal".
I’ve working in automotive since it was only wires and never saw that (or noticed it) happening specially since usually body and powertrain work on separate buses tied through a gateway, the crazy stuff happens when people start treating the bus (specially the higher speed ones) like a 12v line or worst.
