Thank you all. I really appreciate all the great responses. I took delivery of my car in September 2018. The VIN is in the 66,000 range. All three tests were performed within the past few weeks. The temperature for all three test was roughly between 70° and 78°F.
Anytime I am on the highways I do use cruise control for efficiency purposes. Test #1 was non stop, McAllen, TX to Three Rivers, TX (165 miles).
Test #3 was where I was hoping to achieve, at least, close to 300 miles for the full charge. That was pure, 100%, city driving with lots of regen. Everything I did in test #3 was with the expressed purpose of trying to achieve maximum range. I never accelerated hard from a standstill. I feathered all of my starts watching the energy graph closely. Never over 50 mph. The far majority of the driving was between 35 and 45 mph. I did everything in my power to try to achieve maximum range. I didn’t turn the radio on and even the fan speed was set to 1. No passengers, no cargo, just me and hopes and dreams.
Would you say I have a reportable problem to Tesla?
