Anyone have any advice for those of us living in squirrel country? We're planning to put up a carport just to keep the squirrel poop off, but have been worried about possible damage. Haven't had it in the past, but we've got some nasty ones here, and any helpful hints would be appreciated.
Get an outdoor cat. My yard was overrun by chipmunks and squirrels. Socks the hunter cat took care of the chipmunks in short order, and the squirrels saw what happened and decided to stay away.

Shoot...
I just sprayed with capsicum small openings at the base of my garage door where little critters could get in. Seemed like a good idea from a previous post where he used capsucum on his wires or someplace. I should have known that a slight breeze usually blown into my garage when I open the door. Well guess what, now I can't go into my garage let alone the critters!!! Had no idea how powerful that stuff is. I'm sure it works but if you use it BE CAREFUL!

The saga continues. A couple of days after getting the car back, I noticed that the right front parking light wasn't coming on. I only noticed this when I saw my wife pull into the garage one night. After checking all the lights, I determined that the right front fog light wasn't working either. Back to the service center this morning. At least this time I was able to drive it there and they gave me a Model X loaner.

I just heard from them, and it's more rodent damage to a different wiring harness. Again, it's the purple wire that was chewed through. I guess purple wires are particularly yummy. This time they're going to replace the harness rather than fix it for $313 plus tax. Rodents/squirrels are expensive!

Here's the pic.

I think it may be worth equipping yourself with a soldering iron and heat shrink tubing. If the wire is moderately accessible, that's a pretty quick repair job.
I thought of that, but there are some obstacles. Since I don't have a service or wiring manual, it becomes somewhat a matter of luck to figure out where to look for the problem, and I have to hope that the damage is obvious. It looks like for both of these incidents it was fairly obvious if you knew where to look. For the parking and fog light, my guess is that the wiring is somewhere near the light, but for the system failure caused by the first wiring issue, I would have had no idea where to start looking. There's a fair amount of hassle getting to the wiring: jacking the car up, removing the wheels, removing fender liners and/or underbody covers, etc. If you don't know where to look that could be very time consuming. And that's assuming that it isn't part of the wiring harness that you have to access from the inside of the car where bits of the interior have to be removed.

Are service manuals and wiring diagrams even available from Tesla? If so, where can one get them and how much do they cost?

I did a bit of searching, and it seems that you can't actually purchase service manuals, but you can pay for a subscription to access the service information on line by the hour, day, month, or year.

Subscription Level * 1 Hour - $31.88 24 Hours - $106.25 One Month - $371.88 One Year - $3,187.50

If I'm trying to repair wiring I doubt that one hour would be enough, so I'm looking at $106.25 before I even start.

It turned out to be what Tesla called rodent damage. We actually think it may have been a squirrel based on where the car stopped running. I've never had rodent damage to any car over the last 40+ years of car ownership. Do Teslas have particularly tasty wiring? :) They repaired the wiring harness near the front drive unit. It cost $232.50. They initially thought they were going to have to replace the harness, but then decided to repair it.

Here's a picture.

I'm a wildlife biologist and that does not look like rodent chewing. The perfect edge at either end of the "incision" was not done by a rodent. The center portion of the cut that has more irregular edges may be, but I would need more photos. If a rodent chews something, there will be tooth marks on the opposing sides of the object. Were there? They also do not create a perfectly straight cut like you would see with a scalpel, such as in your photo.

interesting. I’ve been reading and saying that in all my years lurking car forums, this seems to be a decent number of rodent damage reports. Would actually be a relief to find out it’s something else. The nest in the glovebox is rodents though, still creeps me out.

I agree that the straight edge doesn't look like it was chewed. I didn't see it in person; the photos were taken by the Tesla service center folks. I can think of a number of possible reasons for the straight edges however. A couple of those possibilities are that the wiring loom may be a split loom similar to the picture below, or maybe they had to cut the wiring loom open to provide enough access to properly check the wires.
