Wondering if anyone else has experienced something similar. I have now owned my 85D for nearly 3 weeks and we decided to take the car for a long trip from SoCal to the Monterey area. Towards the end of the trip, we were driving down a steep grade when the low brake fluid alert came on, along with the red brake failure light. The brake pedal feel did not change at the time. The light stayed on until we returned to flat ground. I brought the car into Tesla service the next day (they were very accommodating and responsive) and I was told that their logs confirmed the warning but that the fluid was only 4 "tablespoons" down from the max level and well within recommended operating levels. They suspected that the level was just low enough to trip the sensor on a steep grade as the fluid shifted below the sensor level. Although this was a steep grade (about 10%), it's not like these types of grades are all that uncommon. I would have to assume that other people are experiencing the same issue if my fluid was just slightly lower than the max level. They also suspected that the car was never topped off at delivery but I find that hard to believe given the car has already been fully "inspected" and topped off on at least one other occasion recently when I had to bring the car in for a windshield washer reservoir that leaked all my fluid on my garage floor. Love the car and the service from Tesla but have not had good luck so far in these first 3 weeks of ownership.
