That's the most important criteria to evaluate the success of Tesla (in addition to profitability). I'd say he's been the most reliable executive in the industry. No wonder why he's the CEO in auto with the longest tenure.
I don't know a single Model S owner that hasn't had the door handles fail. It's a $900 repair, unless you haggle with them for weeks ant threaten to sue them, at which point they'll agree to pay for it, because Tesla knows they don't work.
Oh, and a tire/wheel budget of $3000+ a year is pretty excessive, too. (On Teslas, both are notoriously unable to withstand potholes and dips that even other cars with low-profile tires can just drive over. All that battery weight is a really bad combo with low-profile tires and thin-cast wheels.)
