So my Tesla Model X has a Little Known Bug

Back in early December (2019) I noticed that the regen on my Tesla was not what it should be.

Basically, after overnighting in my garage on a 63 degree F morning, it would take about 25 minutes of my 40+ minute commute before I had full regeneration restored.

On a cooler 37 degree night, I ended up preheating the car for *54* minutes (miscalculated departure time) and, for that 32 minute drive I NEVER regained my full regen.

I contacted Tesla to have them take a look-see, after all, not a couple of weeks earlier they had replaced my Battery Coolant Heater (coincidence?).

Regardless, in spite of what seems like an obvious connection between a battery coolant heater and my battery heater not activating properly, Tesla came back and initially informed me basically that “battery packs are big and can be slow to warm up” and, when that didn’t work they then let me know that there is a firmware bug that is preventing the battery heater from activating.

Below is the transcript of my conversation with Tesla. I’m still waiting for the “future firmware update”.

Basically I’m seeing that Tesla Model X (Premium car) has now become so niche that it basically is not getting much attention at all. And I frankly believe that Tesla service is so overwhelmed that they can’t spend the time on customers such as myself, the earlier adopters who helped to fund the whole enterprise, to ensure that our vehicles are running correctly.

Color me disappointed. I can’t wait to see where I end up on the list of HW 3 upgrade recipients.
