Multiple Errors

[springdaisy82]

I have a 2015 Model S. Last night I got these errors. They went away for a bit and then came back. The left headlight is flickering, and I lost power steering and power braking. Basically, it isn't safely driveable. Any idea what would cause this?

ESP_w003 Traction Control Disabled
BC_W005 Left Headlight malfunction detected
DAS_W009 Automatic Emergency Braking is unavailable
DL_W039 Regenerative braking Unavailable

All at once?
Have you been driving through water?
Ah, you're still in Washougal? If so - yes, you've been driving through water.
One damp major connector could cause several warnings/stoppages.
With a car as old as yours (NOT saying that your car is old, only that it's had more chances for some wiring issue than less used cars might) I'd take it to Tesla for a nice thorough scan.

I would first try a hard reboot and then try reinstalling the latest software.

12-volt good?

I let the car sit all weekend under the car port (I was gone most of the weekend). All the errors have gone away now.

I do think it is related to the snow. I think the left front fendor area has been too packed with snow, causing some gaps between the vendor covers and the wheel well. So it makes sense that water got in there and caused this issue.

Update: There was a grounding rod that was broken off. This is located inside the frunk area on the driver's side. Fortunately there was another one right beside it, so I simply moved the wires to that one, and the problem is fixed.
