He goes on to say that software updates can extend the life of the screens, though does not indicate by how much. It is economically, if not technologically, infeasible to expect that such components can or should be designed to last the vehicle’s entire useful life," Prescott wrote, in discussing the increasing "Electronic components are becoming increasingly more complex while, at the same time, the expected useful life of vehicles has grown substantially. But further comments do not provide comfort that screens in other Tesla vehicles will do much better. Presumably, Prescott is talking only about the vehicles covered in the recall. But owners not covered by the recall could face expensive fixes midway through the vehicle's life. recall with one in China as well last week.) Those owners can get a new screen for free.

The recall covers models S and X built before March 2018. The touch screens can cost more than $1,000 to replace, judging by some quick internet searching. Safety issues aside, this is noteworthy from a cost-of-ownership perspective. "NHTSA has asserted that the component should last at least the useful life of the vehicle, essentially double its expected lifespan," he says, after establishing that the touch screens' expected life is five to six years. In so doing, Prescott says that Tesla's touch screens last for only half the expected lifetime of a vehicle.
