Mechanical failure is a fart in a hurricane compared to human factors when it comes to safety. I'm not gonna ding anyone for being too cheap to put TPMS sensors in their snow tire rims. I'm not gonna ding anyone for a CEL either. 95% of the time it's basically just complaining that an emissions system is not in an optimal state. In a work vehicle setting you do not fix this when it happens. You plan a time in the future to take the vehicle down for maintenance, just like patching a prod system.
