I just want to know if this is common or not, because it is a 4000-5000$ repair that I am not willing to do after the warranty is over. This will be a big factor for me to decide if I keep it or not.
So, anybody knows someone that had this issue? From the lack of positive answers on this, I assume it is still an uncommon problem, which is good news.
The LBC is located inside the battery pack. The battery pack is sealed from water intrusion with a rubber gasket (2011/2012) or glued (2013+). If water got into the battery pack, it would be very
bad, as it would short cells or busbars. Either short would result in cells overheating and over-discharging, which would quickly destroy them and possibly start a fire. A busbar short could be up to 400V, which would almost certainly start a fire.
I have never heard of water getting into the battery pack on a Leaf. You could wait to see if anyone else reports this, but I would seriously doubt it. That said, I would be shocked if the failure was a LBC due to water intrusion. If it were, I would demand that they explain how the battery case leaked water, and confirm that the leak was fixed.
I think it's far more likely that a different computer component was affected. If you want to confirm how common the failure was, you're going to have to understand exactly what failed and where the leak was.
