we have our Model X 90D for 3 weeks now. In general we love the car but there is a big problem. I always feel that the car does not deliver the full 256 mils range as it has promised. We charge to 90% as instructed by the store staff, so the range should be 230 miles. So I have decided to do some test.
After one overnight charge to 90% or 230 miles, we have the car running all the way to 36 miles remaining. The miles driven since last charge was only 149.4 miles. So we lost about 230-36-149.4 = 44.6 miles. Average Wh/mil was 364. What is scary was that the KWh used since last charge was only 54.4 KWH. It almost feel like I have the 70D instead of the 90D, because with the 90D, it should charge to 81 KWH at 90%.
The other thing strange about it is that when I first had the 240V charging outlet installed in my garage, the car charges at 26 mils/hr at 40A, but now it only charges at 30A out of 40A and 20 miles/hour.
Any one seeing similar problems? Any feedback or thoughts will be much appreciated.
