The Model 3 is my third Tesla. I have been driving and advocating for Tesla since 2013. I bought the M3 to replace my wife's 2011 LEAF and took delivery in December 2017. The phone as key option has never worked reliably for her (Galaxy 5) and she is seriously fed up with the car. It works with my Galaxy 7 about 90% of the time. Multiple visits to the Service Center with no success though the Galaxy 5 supports the correct bluetooth version. Given the multitude of phones and implementations of bluetooth this has been a major design fail. Clearly, Tesla did not adequately test this function on a wide range of phones. I was told early on that Tesla would provide a fob at no cost when they were available. Now it appears that the fob, which should always have been available, will cost $150 and will not support essential functions of hands free unlocking and locking based on proximity, or summon. This is a major fail. At the least Tesla should have informed us that we may need to purchase newer phones to operate the car. We are very environmentally conscious and my wife refuses to replace a perfectly functioning phone because of Tesla's lack of testing. As a long time Tesla advocate and TSLA owner I have accepted reduced customer service as the user base grew; however, I now find myself reassessing my enthusiasm for Tesla. I have in the past spent countless hours at various car shows displaying my Teslas, especially the M3 in the early days, and sharing my experience driving electric. I am truly and advocate of electric cars and really want Tesla to succeed, This bump in the road is only going to anger more and more people. We early adopters have been extremely tolerant of quirky design choices, always confident that they would be address, and thy always have been. I doubt that new buyers who are not hard core EV advocates will be as tolerant. Hopefully this fob issue will be addressed as other issues have been in the past.
