Recently, companies such as Verizon, Automatic, and Zubie have introduced a module that plugs into the diagnostic port of most cars. This module keeps track of the status of the car and informs the user of any problems (explaining the problems in plain English). In some cases, companies such as Verizon have introduced a version that is connected to a cellular network. How could such a product potentially affect the customer and the management of automotive maintenance? Think about issues such as how this development could affect activities such as the ordering of spare parts and the monitoring of vehicles to identify systematic problems in product design or component reliability.
