Thank you for the data. A couple of questions for you: What kind of supercharging speeds are you seeing? what is your current 100% rated miles? are you noticing any noises when charging above 80% of heating/cooling fans that S 85 owners are seeing?
Just charged our x90d, delivered June 2016, 54k miles, Vin 05xxx 90%=212 or about a 9% degradation. Our Model 3 with 23k miles has hardly any degradation
Picked up a 12/2016 MX today with 22K miles. On my first charge it only went up to 225 miles full charge. The MX came with battery warranty till 2024. Would this be something I could immediately claim this under warranty?
Only if they find there is an issue with the battery. Normal degradation is not considered a warranty issue.
It’s about 12% loss, which isn’t great for that many miles, but hopefully it will stabilize there and not really lose much more. You can always ask them to check the battery just to be sure there are no internal issues. Did you buy it directly from Tesla?
Status report on a May 2016 MX90D on 2020.4.1 with 90K mile: A normal 90% charge is 212-213 Miles. This seems to be about a 8-9% degradation. It will supercharge at max of 94KW when SOC is 47-51% then drops as SOC increases. This to seems to be what others with similar vintage experience.
I have a Tesla Wall Connector; 18 feet. I believe the reason for the lower charge at 30A is due to a degraded Tesla power cable. The Tesla mobile service guy says that the cable can degrade and you will get lower power. He said you used to be able to purchase just a replacement cable; but no more. I have had the wall connector for almost 4 years. I get full 40A at my daughters house with a Tesla Wall Connector, and full 40A using the Mobile Connector.
Could be because of early version. Mine is a MX 90D April 2017 - brand new it was 262 miles at 100%, now after 47k miles it has 251 miles. I lost 9 miles in almost 3years... not too bad...
I’m in the market to pick up a used X and the 2016 model year 90D is what fits in our budget. Does anyone know what month the cutoff is (about) to get the improved battery chemistry? Also, I’ve been emailing the Tesla used car sales person and he says that they don’t do any battery capacity checks as part of their inspection. I suggested that charging to 90% and recording the rated miles or, at least, comparing the rated miles to charge % for an extrapolation would be a simple thing to do and very helpful.
Purchased a 90D 12/16 MX last month and get 245 full charge and around 218 @ 90% is what I usually charge it to
My 12/16 90d I picked up last week is very similar. 90% is 221 miles and full is 246. That is only 5% degradation in 3 years
