Experiment update: finally got to a low enough charge to be able to plug in (69% displayed)...no pump noise pre-charging!

I am wondering if any of the recent firmware updates has mitigated the humming problem?
I have now charged our 2015 Tesla Model S 85 to 80% three different times. I set it to charge at midnight to get the cheapest electric rates and I am charging at 40 AMPs. After I disconnect the charger the car hums for about 10-15 minutes and then it stops humming. I have also observed very little battery drain after charging.
This is a marked improvement in battery drainage and humming, at least for our car.
Has anyone had anything fixed under warranty repair with this? I have an appointment for a different issue next week, and mentioned this.I have sent 3 different videos and times for them to review and they have not responded since Wednesday.
They are stating that there is a "noise charge" if this isn't an issue that needs fixed, so I obviously don't want to pay for nothing. Mine also occurs at ~90% state of charge - where I charge to at work a few times per week.
Yikes. How do you feel owning an 85 out of warranty?Their 'fix" is the noise you hear. It's to put a band-aid over a larger problem (namely Batterygate/Chargegate issues). So, unfortunately you need to live with it. The noise is the result of an imposed risk mitigation deployed by the Tesla OTA updates. The risk, in this case, being your Model S pack is probably Li-Plated to some degree or is going to be in near future (a bad situation for the pack). The OTA updates have been limiting your capacity, charge rate and the max charge level to manage/control the nasty Li-Plated cells. Running the coolant pumps (the noise) tries to cool down the pack (and also the DU) and drain your what Tesla considers, in this case, an overcharged/supercharged battery so the Li-Plated cells won't overheat. Charging over 79% would result in the noise you hear (the cooling pumps running) to keep the overheated cells cool, which inherently means loss of, if we can call it, excess energy (charge). The ultimate solution is the battery replacement under warranty which Tesla refuses to do.

Ugh, was planning on just keeping this car for a bit to enjoy no car payment but maybe I'll sell it for an X or Y...The same as owing it in warranty :-(

They are going to tell you your battery is in great shape, in fact one of the best they have ever seen for its age. They will tell you to drive slower, try not to accelerate, your mileage may vary, lose some weight, and so on. They have a prepared response for batterygated cars so your answer won't really be for you it's tailered more for people who are range capped and supercharge speed limited, but the noise is caused by the same problem so they will probably give you the standard official excuses.Just saw this thread and I am observing the exact same behavior everyone has described. The symptom is perhaps more pronounced than some since it starts to hum non-stop at anything above 70% charge. I started noticing this shortly after upgrading to 2020.20.1. My car would lose 5+ miles of range overnight after being fully charged and still plugged in. I started searching for possible causes and discovered that the car didn't appear to ever stop 'running'. This could be a 'new normal' but I went ahead and scheduled a service appointment, just in case. I'm interested in hearing if anyone else may have any updates while I wait for the appointment. Thanks!
That is good info. ThanksThey are going to tell you your battery is in great shape, in fact one of the best they have ever seen for its age.

If they try to charge you for diagnostics, demand your diagnostic data printed out so you can post it online. They are legally obligated to give you anything you pay them for, so this either gets you a paper trial for your money or they suddenly change their minds and waive the charge. So far, nobody has had to pay after they asked for their diagnostic data.
I’m new to TMC because of this thread. I have a 14 S85, and the same issue started for me to day.
Timeline:
- yesterday I used supercharger from 20-60%
- yesterday parked the car and started my home 22kw charger. (My vehicle is set on max 80%)
- this morning the pump sound is running. (I will try to attach the video.
it’s been running straight for 3 hours now, maybe longer. I have no idea when it started. My GOM says 310km on 80%. Let’s see what happens.
anyone have any idea about what’s up with this?
