    All,

    Just updated to 5.8.4 (1.49.57).

    Official update notes details that the car will now reduce charge current after seeing some voltage fluctuations making for a safer system. Pictures below:

    Just got .30 this morning after holding off for a week.

    This .57 upgrade sounds really smart.

    So, this update is Tesla's response to this?

    That's exactly what I was thinking... Wonder if this change was already in the roadmap, or if it's a knee-jerk reaction?

    I sounds like they went back to the logs on the garage fire car and saw Vin flopping about. If you can see it, you can dial down your current draw and pop up an error message for the owner. NEAT.
    This is how the fast response software update should be used. Find it, target it to remove the immediate threat and COMMUNICATE what you have/are doing.

    So it can detect issues with an electrician's poor or shabby install that have nothing to do with the Model S charging system itself and reduce current to mitigate any possible issue? Definitely neat.

    Perhaps Tesla have learned from the fiasco surrounding the original 5.8 release? Time will tell.

    My update is installing now. I hope it fixes the sleep mode. 5.6 reduced the vampire load. The first version of 5.8 that I received also worked properly. The second version of 5.8 that I installed about 4 days ago broke the sleep function, and I started losing about 8 miles a day again. Am hoping the sleep mode in 5.8.4 will work properly again.

    After each update you should try toggling the setting that is causing you problems and resetting your main screen. Another member on here discovered that some funkiness happens after an update.

    I am curious about what Tesla considers a "voltage fluctuation" before the software makes an adjustment to the current draw.

    I did reboot the car without success. But I have not emailed ownership about it. Read that other people had this issue also, so assumed Tesla is aware of it.

    Perhaps this upgrade changes the charging system so that it again will be possible to charge with the full current/amps when the power is good. I have had the problem after upgrading to 5.6 that power is reduced automatically. I.e. when 32A is available the car only charges at 21/22A. Hopefully the update will allow full power on good installations..

    The same happened to me when upgrading to 1.49.22, I think it was. A later update (.24) didn't help, it had to be fixed remotely from Fremont by a FW expert logging into the car.

    Hard to know objectively, but this seems like the fastest update pushout yet. Seems they're really getting a handle on the process now.

    wow, 4 updates in a month. Seems like it's getting a bit excessive. Especially since I never got 5.6 but went straight from 4.5 to 5.8 (.22). I worry about quick turn updates - fully tested? I've managed software teams a lot and one thing that is a true danger sign is when you hear "hey, I've got a fast fix for xxx problem - it won't affect anything else, completely innocuous. let's push it out."

    By the way, I don't think this will prevent a problem with an undersized wire or frozen breaker. It could heat up and start a fire before the current fluctuations cause the car to cut back charging. There's only so much the car can do about the external environment. Note I think the change is a good one - it would probably have caught the faulty UMC problems that we saw earlier.

    So much for WiFi connected MS's getting the first push of updates. Been connected for 48 hours and nothing.

    It just started rolling out < 24 hours ago.
