Hello everyone! I have looked around a bit but haven't been able to find a similar issue.
Model S P85+ 2014
Main battery was replaced at the start of this year after a total failure
Around the end of September, I began to get GTW_w018 (Electrical system power reduced) errors that would show up, cut my AC, and then disappear a second later a few times every other drive or so. Over the last month, I have noticed that they only show up when it is above ~70F outside.
That was relatively harmless, so not as much thought was given to it as it probably should have.
So, his morning I went out to run an errand, and the car was powered off, upon turning it on it flashed a bunch of alerts at me (GTW_w018, DI_u014 Voltage supply too low, and GTW_w406 12V Not Supported) that said that there was low power so systems were shutting down, and the car was not ok to drive. Yesterday there was a very heavy rainstorm that I had to do a lot of driving in, I assume this may have caused this more serious issue.
Does anyone have thoughts on what it may be? I think I will need to make a service appointment, but I want to see if it happens to be something fixable by me, and if not then go in with information to hopefully cut down on troubleshooting time.
Attached are photos of the service alert pages. The first was taken on October 1st showing intermittent GTW_w018 errors, and the 2nd/3rd were taken this morning, the blue lines on number 2 show the breaks in time.
