I've tried to get help from Tesla to no avail, so I guess posting it here and hope for an owner uprising is the only thing left. I LOVE my Teslas, but a BIG part of that was how regenerative braking was so good, I almost never needed to use the brake pedal. As of a software update several months ago, the regenerative braking behavior of my model S is DRAMATICALLY reduced ALL OF THE TIME... hot, warm, cold, half charged... it doesn't matter. This is not the same as when it's at or near capacity and can't be charged, and I live in southern California, so unless 60-80 degree weather is considered "cold" then temperature is not a factor either.
I've tried to put up with it thinking Tesla would release a fix immediately because of how dramatically it changed the driving dynamics of the car, but here I am several months later still feeling like I'm driving a completely different car (when it comes to braking). I'm still letting up on the accelerator at the same places I have been for years only to find that I'm left hitting the brakes HARD as I approach stop signs and intersections that I used to EASILY come to a full stop at without so much as thinking about the brake pedal. It's almost as if the "Standard" setting has taken on the "Low" setting parameters... although I can't imaging it being any lower unless the new "Low" setting really means "disabled."
Not only is dramatically changing the way my car BRAKES a terrible idea, it's DANGEROUS! PLEEEEASE can I have my "FULL" regenerative braking back?!
