Another Superbottle and Coolant valve failure - 2018 LR RWD at 108k miles

[CubedRoot]

It finally got me. My 2018 Long Range RWD with 108k miles on it finally started showing the following two error codes in the service menu:

VCFRONT_a210_coolantValveCalib
VCFRONT_a249_coolantValveBadMode

Some of the symptoms I was having that made me check the service menu was that the car would never precondition to the right temp. I could be navigating to a supercharger 140 miles away and it would precondition the entire time, but when I arrived, it would charge and show that the battery was being heated for a decent portion of the charge. My charging curves were also pretty limped at times. In addition the AC was having a hard time keeping the cabin cool and the radiator fan would run wide open even when taking it easy and driving slowly or at highway speeds. I also verified that something was up by running a thermal systems check in service menu and it failed.

Contacted Tesla, and this will costs about $986 to replace. Replacing the Superbottle (Part number: 1111740-00-A) and 5-way valve (Part Number: 1133873-00-A). Total parts was $376.76 and labor was $504. Its scheduled to get replaced August 30th.

Anyone else gone through this yet?

The only good news is that the failure didn't cripple your car!

under $1k for a new AC system main component isn't that bad... but 5yrs / 100k miles isn't a long time or mileage *at all* for such a main component to fail...

My error was ‘high voltage needs to power up’. 2018 LR 96k miles. Frankly, i don’t have much confidence but then I don’t work on Teslas. Charge is $1318 which includes 390 for diagnostics. Not a happy customer.
