In the fall of 2012 a referendum in my home state passed with a large margin to make Massachusetts the only state (still is) where an independent shop can sue the manufacturer of a motor vehicle (gas or electric) if the OEM did not keep the playing field level in terms of service information, replacement parts, tools, equipment, software updates, scan tools and training information. It is NASTF (National Automotive Service Task Force) with teeth. The law has never been tested but it is clear to me that Tesla is in violation. If your Tesla failed our annual strict safety test you must have it fixed at the repair shop that did the test or tow it to the shop of your choice. Every car in my state gets tested every year. Obviously our emissions test does not apply to pure electric cars. Most car owners bring their vehicles to the shop they like and if something is wrong it gets fixed. Most owners will drive to another shop if it failed safety not knowing it is illegal. Those are the facts. Expect things to change soon as Tesla delivers more Model 3 cars. Currently if a Tesla Roadster, Model S or X failed for a safety defect (like a loose ball joint) you must have it fixed by Tesla, even out of warranty cars. That is not allowed in Massachusetts the way I read it as any shop should be able to make the car safe again.
