The cars display of range at the little battery icon is useless. On the other hand, the navigator is fairly accurate at predicting remaining battery percent at the end of a trip. So use the navigator to find a good estimate of real range.

Used fuses are likely in the same condition as the one you are replacing. Why would you do that?

My 2016 90D just gave me this message also. Dealer did it. About $350.

Don't rely on the cars display of range to change in proportion to actual battery degradation and real loss of range. My 2016 Model S has had a large loss (~30%) of actual battery capacity and actual range. Meanwhile, the cars display of range has only diminished 5% to 10%. I would make sure...

2016 S 90D. About 360 wh/mile over 80,000 miles. This is with a moderate driving style. Real full-charge range about 195 miles. Usable battery capacity about 70 kwh. Tesla shop says that everything is normal.

Scheduled charging again failed to occur, leaving me with inadequate energy for my day. This is a sporadic occurrence. But even once in a while is too much.

All that and you didn't tell us which car it was? Model 3? Model S"

When you say that the range is 292 miles, is that the actual number of miles that you can get? Or is it the cars display of range? Important difference. For example, my cars display of range was 275 miles. At that time, the real life achievable range was only 200-220 miles. Worse, usable battery...

Good for you. Good idea to get an "inventory" car. I also got my Model S that way. Big discount. Small mileage hit. I do wonder if the sales people abuse the batteries of those cars by keeping the batteries at 100% for all those months. The "90" kwh battery in my 6 month old car had a usable...

Well, let's see. My 280 mile Model S delivers 200 miles of real range. So the the 400 mile model should deliver maybe 300 miles.

Sorry Ran. I am just not understanding most of what you are saying. At 6 months of age, my cars battery had 72-73 kwh of usable capacity. And my achievable range was 70-75% of the displayed Rated Range (200-220 miles). So, lots of things wrong and would not be expected. First, not able to get...

In the summer of 2016, the new Model S 90D cars in the showrooms displayed a full charge Rated Range of around 280-285 miles. The usable capacity of these batteries when new was described in several places as 81-82 kwh. 72-73 kwh is certainly not a normal usable capacity for the 90 kwh battery...

Yes, I know that I said the same thing a few times. I felt if appropriate because it appears that many readers read only replies to their own messages. Also, the fallacy of rated range display accurately revealing battery degradation is so widespread, and recurs so frequently that frequent...

Many of us have found unexpectedly large loss of battery capacity (and loss of range). Battery degradation may or may not be revealed by a decrease in the displayed full charge range. If you ask Tesla, they will say nothing is "wrong" with your battery until or unless a fault is displayed...

I suspect that many owners would be surprised and disappointed by the extent of their battery degradation. If they knew what it really was. (My car shows a 5% decrease of rated range while it has 15% degradation) The display of full charge range gives false assurance of minimal degradation...
