Remember how someone claimed their Toyota's brakes refused cooperating, and even though Toyota managed to prove it was the user-installed floor mat issue their sales fell through the floor and Toyota had to rekindle them with discounts, 0% financing and service guarantees?

People don't do deep research and follow-ups on automotive incidents. Best-case scenario is they have someone do it for them, like Consumer Reports. Typical-case is they see a car with a logo on TV or on top of a salvage truck and they make a mental note to avoid that manufacturer.

If it was done by an unofficial maintenance person, then no, not unless it's proven that it was Tesla's fault instead of the maintenance person.

Not sure how it works with official maintenance garages though. I'm sure there's a liability waiver signed somewhere, else there'd be a lot of big lawsuits about improper repairs by official maintainers. Unless there is no such thing as improper repairs. IDK

The media would blame Tesla, they have an agenda.

The media is plural, it has many agendas. So?
