I felt the opposite. Tesla's answer came across the worst to me, and reads to me with the over-specificity of a student making excuses for why their paper isn't done on time.

> "It was a supplier-related issue".

Passing the buck is really not a great look to start with. It makes the rest of the response seem like a series of excuses.

Tesla chose the supplier. Tesla built and inspected and sold and shipped the car with those parts. This is a Tesla-related issue. The only time Tesla should mention a supplier issue is in response to, "why can't you sell me a car?"

> "[It] did not pose any threat to vehicle safety".

That's good, but this isn't the safety survey.

> "[T]here was a[...] false service alert [... that was fixed] within two weeks of being reported".

I'm not even sure how to react to this one. Bringing my car in to be told "false alarm" is really not reassuring. And two weeks to fix a false alert doesn't help me - I've probably already brought it in for service.

> "This proactive approach to improved reliability is one of the reasons why Tesla is the highest rated car brand among consumers, according to Consumer Reports." (Paraphrased:) Our cars are the safest and best performing, and Model S is #1 in satisfaction.

To me, blaming a supplier for the issues is a terrible way to start, and this is likewise a terrible closing.

"You just fell in the rankings to come in 3rd to last in our reliability survey. Any comments?" "Our cars are the safest and fastest and we have always ranked #1 on your customer satisfaction survey."

Those stats are undeniably good. They also make me think those are the stats the company cares about a lot more than reliability.
