We are good, no worries here Even better with the patch for the temp sensor coming.
From what I read here the failures at colder climates are much higher, probably related to the fluid in the tanks freezing at some point.
Replacement of the active tank is actually not a big deal. A few bolts have to be removed, a few rivets and a few clips popped out to remove the bumper. Once the bumper is out there are 2 screws, few electrical connectors and a few quick disconnect hoses. I need to check the exact work hours in the KSD, but shouldnt be much.
