Greetings all. I have a recurring rotor overheat issue I'd love your thoughts on.
June 2018 bought rwd long range model 3.
April 2020 rear motor fails and is replaced under warranty.
December 24, after 45 min of driving in 15F temp, rotor starts to overheat at highway speeds causing significant loss of drive power with speed decreasing from 75 setpoint down to around 60 on mild uphills despite accelerator pedal fully depressed. Similar situation occurred a week later.
Service determined motor coolant was overfilled from the factory at 2.5 L instead of 2.3L
Feb 3 2021, same issue. 10F, after driving 40 min with heater on, loss of acceleration / limitation of drive power, decrease in speed from 75 to 55 while going up a moderate hill. I assume this will be another rotor overheat.
Any idea what would be causing inadequate rotor cooling in very cold outdoor temperatures? Service appt scheduled for Feb 10.
