About one month ago I realized that my usual 50% charge at home, 48amp, Tesla charger was NOT staying at 50%, but instead was re-setting the charge endpoint at variable times after I set the 50% as the limit. I use TeslaFi, and had 4 other apps related to Tesla charging to help me locate alternate charges for a drive between Austin and Taos for a ski trip.
I first made sure the locator apps were uninstalled on my Samsung Note phone, and that 50% was the saved setting in TeslaFi. I would then CLOSE teslaFi on my laptop as a just in case, so that only the screen in the car and my assigned cell phone were in touch with the car. I set the charge limit in the car AFTER plugging in, and shut down and rebooted my phone without loading the Tesla app. Loading the App about 5 hours later shows that it’s charged up to 70%. So I push the charge limit on the app DOWN to 50%, leaving an excess of about 20% charged. In just 10 minutes, the app resets the limit UP to 70% again. Now, the TeslaFi has been and IS set to 50% and 48amp. I suspect at this point the last update I got is somehow wonky. (2022.12.3.12) . In addition, every morning commute at 6:30am to my pharmacy about 40 miles away, if I choose to FSD, within 5 minutes I get a COLLISION ALERT, due to nothing in the way but perhaps a shadow on the street at <40 mph. Which apparently dings my safety score as well. I wash the car at least weekly and hand-dry with cleanfresh microfiber towels, particular attention to every camera location so the cameras can “see” well. Back to the charging problem, which is really frustrating. Until this started happpening I was seeing a chart of my battery life compared to all other Y models at my mileage, where my battery statistic was significantly better than 90+ % of all other Ys. Because this sliding scale charging has started pushing me up to 100% at times, all on its own, my chart is showing a distinct drop towards “everyone else”. So I have uninstalled every charge locator app, unloaded TeslaFi from my browser when I leave work, and STILL the charge limit setting keeps resetting itself up and up. I now have Alexa set an alarm based on the estimate the Tesla app gives me of how long to charge to 50%, and then get up and go downstairs and UNPLUG the freakin’ charger so it won’t overcharge me beyond 50%. (50% gives me a 30 to 40 mile cushion for my daily roundtrip commute).
I can tell the app to STOP CHARGING, move the limit point back down from 70 or 80% that it snuck up to, to 50%, and even then after 10 minutes or 15 minutes it resets itself back up to a point beyond the current charge level. It did NOT used to do this, but AFAIK I have done nothing on my end to cause this, other than allow the updates to happen. The only other recent idiosyncracy I have is that I used to be able to vent the windows in the morning at work, and they would stay open all day. Today being a typical central Texas day, the vents closed at some point in the morning after I got busy as a pharmacist, and when I checked it late in the afternoon (12 hour shifts) it was 145 degrees inside and the vent setting was CLOSED. <sigh>
ANYONE else experiencing charging that won’t behave and stop at the original setting in the dashboard or in the Tesla App? Anything else sound familiar? Suggestions? Is there a log I can dig into that will iterate WHAT triggers a change in the “charge limit” setting? Love my Tesla, but….
