I'm based on the outskirts of Bangkok which is currently a "high risk" area for an impending flood that's heading my way, sometime in the next couple of days. I'm hoping that it'll not be more than 1m of flood that I'll be facing with, however, I need some advice in the worst case scenario if I can't find an elevated place to park my car, what's the best measure I should take? Should I disconnect all batteries? Thanks! John
Sorry to hear about this John. We have seen from someone else on this board that a flooded Prius is not good. The HV battery is completely disconnected whenever you turn it off. Just try to keep it dry. [edit] - here is the link to the other flood case.
I've known folks in flood/hurricane areas of the USA and they seek parking places on inside walls of upper floors of hotel parking structures. The upper floors stay dry and the hotels are very motivated to clean up and re-open to house the recovery personnel.
Its not the batteries you have to worry about - its all of the electrical harnesses and connectors that will get wet and muddy and eventually corrode if the car gets flooded. Insurance companies will usually take a total loss on the car if it is subjected to flood.
