While I don't think this specific issue affects me, I couldn't agree more. I specifically paid for the 4 + 4 Annual Service plan primarily for this reason, and so far I don't believe I'm getting anything above and beyond what other folks without the Plan are getting when they take their cars in. - - - Updated - - - I think this might be an artifact of how Tesla constantly changes the Model S specs and features as opposed to traditional car makers who increment by model year. I remember when Cadillac added remote control features (via an OnStar app) to the 2010 models and my 2009 didn't have the feature nor could it be upgraded. I was disappointing, but knew I had an '09 and it was '10 and newer feature so just moved on. With Supercharger limitations, Parking Sensors, Cold Climate Pkg. and so forth I believe you just have to think of it as having an "earlier model year" car. I think it's quite common for newer cars (or computers or smartphones for that matter) to just keep getting better.
