Back in the year of George Orwell i bought a brand new car and proceeded to take it apart and investigate the engine control unit. Based upon that study i discovered a design 'feature' that was prone to failure and repaired hundreds of these units for a nominal fee and even provided free phone support to help folks troubleshoot and make the repair themselves. Now, after all our patents are belong to you, i was considering to buy a tesla in order to investigate the various subsystems to determine if there might be opportunities for a 3rd-party troubleshooting and repair service, to satisfy some curiousity about how it works, and hopefully be able to put it back together and still drive it. After reading thru this site i found some really interesting information about the battery and user interface that was shared by other curious folks who have the knowledge, skills and ability to do a detailed analysis of the systems--to them i say thank you very much for sharing. In addition there was the discovery of the lack of access to repair parts and diagnostic information outside of the factory-certified providers, and the total wireless control of the vehicle by the factory, e.g. turning ethernet ports and the ability to charge off... Sure the vehicles are under warranty for now, and there is no need for any outside repair services--maybe there never will be?
