Check Hybrid System Low engine coolant?

Probably not to be honest about it need to scan it for the codes quick things come to mind like inverter pumps but need to check your codes see if there's any electrical issues

 

"battery coolant" is this one?

 

I don’t think it’s any of those you mention that is causing it to not start. I would take out the excess brake fluid immediately with a turkey baster or something similar. (Don’t use it for food after). Excess brake fluid will heat up and expand. This may cause your front driver side brake to engage by itself and heat up that wheel/area. I know from experience, not in a Toyota though. Top off the low coolant if it’s not excessively low then move on. If it’s really low then need to investigate why.

Rats! They’re known to eat through wiring harnesses. Gotta look for any damage to the wiring…
