Have them screen shot you the service history list from the app and and send the PDFs for each service visit. If there are recurring issues that haven't been fixed, they'll be in the service docs. Non of it will be in the Carfax.
The app won't show more than the last 10 visits. If there have been more than 10, I'd pass.
To what end? What info can be gained from this that's relevant to the sale, especially for a vehicle still under warranty?
The # of visits isn't really relevant IMO. If a car had been in 10 times but 5 times for fixing the same handle they couldn't get right or needed further adjustment... is the thing a lemon? Not hardly.
I've bought/sold 7 used Teslas now and not once have I requested a screen shot of the service visits. This seems like an unnecessary request and to refuse to proceed with a purchase because of anything associated seems even more dramatic.
TBH if a potential buyer requests that screen I'm probably not wasting my time with them because I've never had that requested of me in all of my vehicle negotiations. I don't waste my time with needy buyers with odd requests as there's plenty of reasonable buyers out there who don't make pointless requests.
That's fine, more cars for me to buy I guess.
OP you're going to get a LOT of opinions on car shopping and some are routed in first-hand experience and others are from fantasy land. The only thing that matters is that YOU do your due diligence before spending a large sum of money. This applies to most things but especially vehicles.
Don't rely on any sort of vehicle history (read: CarFax) as sole source of information. If the vehicle history is clean... it doesn't mean it hasn't been wrecked/repaired. You still need to inspect the car carefully. All a vehicle history report tells you is where to inspect more closely if there's a repair listed.
The cars you're looking at are likely still under full manufacturer's warranty so this will narrow your thorough investigation to impact/repair and other cosmetic things not covered under warranty. Sure, it's good to know the mechanical condition and what _may_ need repaired but I wouldn't stress too much about those items that need attention, let alone what items have been addressed previously. If you're buying private party I would put more weight in the seller him or herself. If the person seems shady or is a prick... I'd walk away. Trust your gut. There's more cars out there and more sellers and NEVER buy or sell on emotion or under pressure. Stay logical and w/o emotion to avoid making quick decisions you'll regret in the future.
Case & point: Yesterday I test drove a Rivian R1T for a buddy who is out-of-state. The seller is private party and he wanted me to go get eyes/hands on it for him to make sure there was no dramatic damage that wasn't disclosed and that the seller was legit before he wired the full purchase price ahead of his arrival to take delivery. During the drive, I raised the truck tot he highest setting and did a launch from a stop. The truck made a shutter/grinding noise form the front indicative of the dreaded front half-shaft failing symptom. The owner was surprised by the sound and I could tell he felt the need to try to defend it as he had never heard it before. In this instance, I was more interested in the owner's reaction to the noise than the noise itself. I knew that the issue would be fixed by Rivian under warranty so it's no reason to walk away from a sale. Now, had the owner tried to cover things up or reacted in an unexpected fashion it would be more of reveal on the sellers character which was also being investigated. Moral: easily fixed warranty items are just that. Don't let something simple blow up a deal.
Bottom line is that nobody on this internet forum will have to live with whatever YOU end up doing. This is why it's important that YOU are comfortable with the deal regardless of what anyone on an internet forum thinks. Ultimately, you will be the one living with the decision.
