I've had my Model S for a few years now so lets get the "this happens every winter" people away from their quick responses of 'this is what happens to regen braking every winter. I've checked with some locals and they too have more aggressive regen limiting and no battery preheat.
The past few years in winter when I would preheat the car via the mobile app the battery heater icon would show up and the car would have at LEAST a little regen braking when I was ready to leave. This year I have zero battery preheating unless the car has been sitting for a LONG time in temperatures below 15 degrees. However even then the battery heater icon only shows up for a short period and nowhere near long enough to gain any regenerative braking.
Something was done to the software on purpose. I say on purpose because the heater does still activate but under new circumstances just seemingly at new temperature set points. Why? I have no idea but no regen, burning through my brake pads on a 20 mile hilly backroad commute is bull. I have the excess energy but instead I'm being ushered into a $175 hour Tesla shop fee brake job. No thanks. So for the past month or so I've been sitting in the car with the it "navigating to a supercharger" to trick the system into preheating the battery in anticipation of a supercharge. The car is willing to preheat the battery if it means alleviating Supercharger congestion aka bad press for Tesla but unwilling if they can gain some money on a brake job. I thought the service centers were not supposed to be a source of revenue? Right.
*Side note some real bad debugging. When I preheat the seat heaters don't come on until I've actually sat in the car. When I turn the car on the HVAC reverts to the settings I had when I left the car (completely ignoring what I had set the HVAC to via the app) and at times the seat heaters don't follow my selection. I've had a burning hot seat at level one while other times having no output on level3. It seems to correlate more withe the temperature I've asked for and the 3 seat heat levels are actually just a on/off placebo switch.
The constant meddling with software, removing and adding features, while screwing other functions up has left me strongly debating staying with Tesla despite following the company since its inception. I used to be excited by software updates. Now I cringe pressing the update button not knowing what may get broken this time in exchange for slapstick "comedic" flatulence or tacky backseat romance in dash fireplaces. I loved this company and admire their mission to move us away from fossil fuel consumption. It's a business yes but I'm wondering if it's become more about the money and twitter headlines on new products. A year from now when I have to make a choice to stay with Tesla or switch brands I hope Tesla gets its act together.
