The service seems like a waste of money to me. I was in a similar position, but I went ahead and did it.
My Tesla has been in for mostly warranty "work" (not maintenance) 12 times before I hit 50k miles. I had a few things that needed fixing before I went out of warranty, and I said "eh, why not, let me pay them to do the service maybe they'll find/fix something". They did not. It was routine. This was what was done for $850
The OEM wipers lasted a while, then I replaced them with Bosch Icons which lasted about a year. And now the service replaced them with "wipers". I use that term loosely. They are complete cheap crap. The crap they put on was streaking within a month. I've never had wipers go bad that fast, not even $5 wipers from Walmart.
Then there's the alignment...
1. In hindsight I never got an alignment log, which shows the before and after
2. I came in to Tesla at 45k miles to get new tires, and they told me my car's alignment is fine, no need to get it aligned (I asked them if it's needed to just do it). So for the first 45k miles no alignment needed, and then bam in 5k miles the car needs an alignment. I get it, it can happen. But it just seems... almost as if they put it down to pack more into the $850 service. It doesn't say they performed an alignment check and it came back fine, it says they performed a 4-wheel alignment. It's likely not the case, but who knows.
So yes, they did everything they were supposed to do. But I don't feel my car needed most of what was done. I can do most of it, besides the battery fluid flush, myself. And $850 is steep for what was done.
