Ask them where the corrosion was present. If it was located around the heater plugin, then definitely no. If it was near the battery, maybe?danowpg wrote: ↑Fri Sep 06, 2019 4:41 pmYeah, that's why I wanted to post everything was so that if someone else had an issue, they could learn from it.Lothsahn wrote: ↑Fri Sep 06, 2019 2:05 pmThanks for posting the root cause. That helps if we have any other fellow northerners with HV battery issues. Btw, $359+$180 is CHEAP compared to some of the diagnostic costs I've seen around. I would be very happy about that (and leave them a good review). This is why they quoted you $600 originally--turns out it wasn't a battery warranty issue and it's better to be up front about costs than to have a surprise.
My big question is still what IS the main cause?
How did it get corroded?
Is it related to the battery plate recall where corrosion could be introduced?
Where was the actual connection that was corroded - is it within the battery pack enclosure? If so, where does the battery pack warranty end and the electrical warranty stop?
This last question I think is really important. I'm assuming there's a connection somewhere in the battery pack for the main heater?
On the flip side, if I do find out that it has fixed my heater, I still have a quote from 1.5 years ago when my heat stopped working for $3,200 Canadian to replace the heater. Maybe it's still broken, we will know more tomorrow.
My understanding is that the recall was only to fix an issue where the battery pack could corrode through, break open, and expose people to high voltages. They basically replaced some plates and brackets to deal with potential corrosion issues. I highly doubt that had anything to do with your corrosion--corrosion around HV connections and plugs.
Also, the battery is fully sealed, so even if the car was driven through high water, it wouldn't have affected components inside the battery (unless something crazy happened). I know someone with 3 flood damaged Leaf's (from Katrina), and when he took the batteries out, they were 100% functional. The rest of the car, not so much. The cars were submerged, in some cases, up to the windows.
