The fuse is blown? What about if a rat chews through the battery cable. Where’s a spare cable and what about the poor rat. Have a beer my mate and stop worrying. I’d be more concerned about the battery going flat in your example. Did you leave something on or is it knackered? This will stop it happening again.
Yeah... I know.
Something definitely was left on - that's why battery died. But my point was the trouble I went thru. Frankly, I think with EPB system - not many are aware of this possibility ; that can get completely stuck. As for the trunk business - ah well. At least I can still wriggle into the trunk area after lowering the rear seats. Some due to their age/size may not be able to.
As a tacit decision, have decided to avoid using EPB if my car's going to be parked someplace > 4 hrs with 1 exception - if the road's inclined.
