I received my 2022 Model 3 LR back in March 2022. It has a stated range of 358 miles. Since purchasing it I had never put a 100% charge on the battery. I set my charge limit to 80% as recommended. This produced a consistent 278 miles. Back in November of 2022 my wife and I took a longer trip, so I charged up at home to 95%, which yielded 338 miles on my charge indicator on the screen. That seemed to be about where it should be since 95% of 358 is 340. By that time I had reset my charge limit for my normal charges to 85% because that produced 302 miles of charge making it easier for me to mentally keep track of things. Then a couple of months ago I noticed after an 85% charge my car was only showing 278 miles again, not 302. At first I thought it must be due to the fact that I had been running the cabin heater occasionally during some cold snaps. After a couple of identical charges I intentionally avoided running the heat for a charge cycle to see if it would return to 302 miles, which it didn't, still 278 at 85% charge. Next, I checked my setting to see if somehow it had gotten reset back to 80% charge, which it had not, still set at 85%.
A couple of weeks ago I was planning a short trip, so for the first time I set my charge to 100%. The car showed 327 miles on the full charge. In the meantime I've been reading about how Tesla had reduced the charge capacity on some Model S and Model X cars back 2019 with an OTA update and explained it as a safety issue when they were questioned about the mileage reduction. A class action lawsuit ensued with Tesla losing and being required to pay the affected owners $625. I recently read a story saying a similar thing is happening again with some Model X and Model S cars. This got me wondering if an OTA update might be responsible my my mileage reduction? In my case, it certainly didn't follow a pattern one might see with normal battery degradation, which would be a slow drop over time. Mine occurred instantaneously, going from 302 on one 85% charge down to 277 or 278 on all subsequent 85% charges. I always charge at home with Level 1 or Level 2 charging. I've only had one five minute DC charge soon after purchase just to test if that function was working properly. So, my question is: Have any other 2022 Model 3 LR owners noticed anything similar with their charge limits?
