When I got my car last October, I had very high energy usage on all drives. One wheel had huge amounts of brake dust while the other three did not. One day, my car smelled of burning brakes and immediately energy usage plummeted. Service checked it out and couldn't find any problems. The car has been super efficient since then, even through the winter. Until today. Energy usage spiked. Was over 350wh/mi on my commute that is normally 290. Loud grinding sound. Grabby brakes. Overall sluggish to drive. I called roadside assistance and they told me to stop driving and sent a tow truck. Tow truck driver said it's not the first Model 3 this week with the same issue. Could it be the latest software release?
I checked temp of the rotors and calipers and one side was about 10C higher than the other side, but not crazy high.
