    Hi all. Happy Holidays. I kinda want to do a poll to find out has anyone been experiencing the same "issue" as I am. I am not sure if this is an issue I need to bring up to the service center but lets say the night before I will set a charge of 90%. However, the next morning I wake up...it will charge sometimes to 95 or in this case 98%.

    It doesn't happen all the time. Any thoughts?

    2 years into model 3 ownership - yep happens to me occasionally. I think it’s due to the temperature changes from overnight to daytime and rebalancing

    It shouldn't happen. Certainly not 90% to 97%. I would bring it up with the service center. Also, you should watch it sometime to see if it stops at 90%, and then resumes later, or something else is going on.

    Hi Bktiger86,

    I have seen some other reports of this on some of the recent software 2019.36.x.x
    Are you charging on a HPWC?
    If you are on 2019.40.2.1 and are still having the problem contact your Service Center.

    I am using the HPWC. The firmware version is 2019.40.2.1. I will keep an eye on it to see if happens more consistently.

    Very interesting...yeah I'm not sure if it is weather related or not. I live in California and lately it has been pretty cold in my garage.

    Do you have a service like TeslaFi that can monitor the charging? This can give you a bit better insight as to what is happening.

    This happened to me for the first time in years of ownership (two cars since 10/2013) when I tried the new "depart at" option in the charging scheduler. Once I realized it was still charging even when the car was at or above the charge limit I had set, I immediately went back to my the start charge at 2am option and it hasn't happened again since.
