Tesla mode 3 LR 2018 full charge showed as 281 miles

Tesla mode 3 LR 2018 with 21K miles
Full charge showed as 281 miles yesterday. It showed as 316 miles last September.
The weather here in Dallas is around 52 degress F.
Is this an issue OR not an issue.

Comments

  • No. Just try recalibrating the BMS. Lots of threads on this topic.
  • No issue. Energy bar is a guess o meter. Estimated driving distance.
  • Normal. This comes up about once a week. Here's an article I wrote with more details on understanding range, range inaccuracy, and how to calibrate it:

    Depends on Rated Range.

    Per Tesla 5-10% battery degradation in first year is "within normal limits". I have 6% after 40k miles in a 2019 but I charge at fast DC charging and big discharge/charge differentials which is worst case scenario for battery degradation.

    To get a better handle on state of the battery, try TeslaFI.com, StatsApp for Tesla and Battery Health. The three programs use the car's data to show you how you battery degradation is going.

  • Fishy is present and, as usual, is spreading FUD with a manure shovel. Public Service Announcement:
    FISHEV is a known troll of several years standing and several user
    names who pushes an anti Tesla narrative. Please
    take his opinions with a grain of salt, avoid any advice he may
    suggest, and do not let him implant any Fear, Uncertainty, or Doubt
    about Tesla or your car into your own opinion.
    Fishy especially spreads its FUD on this forum in the hopes of convincing newbies and potential buyers that Tesla is All Bad, and has been doing this against all the facts. The entity uses, or tries to use uncheckable $BS at every opportunity, with the above being a prime example.
    It's considered quite likely that FISH may be one or several employees of a commercial shill farm, paid to disrupt the forums and Tesla in particular. The one time a couple of years ago when FISHY was publically planning to meet with a number of members to confirm his/her/its bone fides, the meeting was cancelled by FISHY. Then, right then, an apparent sock-puppet by the name of raqball showed up and said FISHY was this extra nice person. People then checked into raqball; when raqball was asked, flat out, if he/she/it was a sock puppet, raqball went, "What is a sock puppet?" and.. immediately canned the thread, something that the originator of a thread could do. Makes it unsearchable in Google, don't-cha-know.
    As to whether any of these types above are a natural human being, well, that's in question.
  • Mine fluctuates between 278 and 290. Normal
  • @rnkana_98203661 My 2018 LR RWD with 30k miles still shows ~318 miles at 100%.

    Did you change your charging habits in the last year? You can try helping the car recalibrate though the following info is theoretical but plausible...

    Let your car sit sleeping over night at multiple charge levels, for example every 10%. Make sure sentry and summon standby is off.

    The theory on this is that the BMS has to get multiple voltage readings to make its estimation of capacity. Before it takes a measurement it wants to make sure the voltage is stable which is why it needs to be sleeping for a while before it takes a measurement.

    This obviously will take a while to get multiple charge levels and it may or may not work. You will know if it does work, but you won't know if it doesn't work.

    Further reading on the theory can be done here https://teslamotorsclub.com/tmc/threads/how-i-recovered-half-of-my-batterys-lost-capacity.204712/
  • It's normal. Don't worry about it. That miles display thing isn't accurate.
  • By the way Fish is anti Tesla hater and troll.
  • I have 65k miles on my march delivery 2018 LR RWD. Full charge comes in at 308 miles
