Yes, it sometimes is a a problem. I have had two mobile service visits. One to replace the 12 V battery that was done under warranty and happened quite quickly and on time; another to replace a smashed door mirror that was delayed by a week because of a mistake in their internal processes. The biggest problem I have with Tesla (the company not the car) is that they are very bad at communication. Unlike the supercharger network, which is very nearly ubiquitous in northern Europe, their telephone service is almost impossible to use because it is simply permanently overloaded. This is a major problem if you are trying to call them from a mobile phone in an area with poor coverage such as when one has blown out a tyre by hitting a pothole on a rural road in north Devon in the pouring rain.
