Yeah but maybe they know the root cause and maybe they are right this time. At least the response is positive better than response specifying hopefully.Engineers aren't in the business of building "Temporary" fixes. Or, to put it another way, the past six PCS revisions were all "permanent" too... right until they weren't.
also hopefully your replacement is installed properly. one of the earlier replacements resulted in the need for a full battery pack change. but this was one of the earlier ones and it was on a YT influencers very heavily used CTs. (TesLatino) hopefully the rest of the fleet will benefit from that learning case.
not likely since the drive is not activated during charging .

What happened with mine was that they re-used the old seals when they replaced the Power Conversion System. When I left to continue my travels, a month later the battery started failing to hold the charge and it turned out to be that dirt from all the trails I went to, made it into the bay and shorted the communications and/or power harness for charging the pack. Apparently that caused damage to the pack, so they provisioned a new one for my truck, and so far, so good. Now I am over 120k miles. The only other issue I had was one of the suspension valve blcks needed to be replaced and the driver window button to open and close the window snapped. I have the new switch with all four to replace it myself. Some day.
