Return of phantom 16 amp charging

- Start date
Same for me, I had to put a call in!!! I’ve leased mine so maybe just another complication of that?
Came here to see if I was alone. I updated to 2020.12 a week ago. First charge last week was fine but woke up this morning to find the car still charging when normally it would be finished and speed at 4kwh rather than the usual 7kwh. This is a Podpoint charger that has worked flawlessly on an i3 and then the Tesla for 6 years. Immediate thought was issue with charger due to its age but clearly its a software issue based on the comments here. I guess I will log a service call like others have.

Any errors in car? Any electrics tripped? That sounds similar to what I witnessed twice on 2020.16.2.1 although it occurred right at end of an otherwise successful charge.

First time charging on sw 2020.20.12 and had the same issue: car was charging between 17-18 A on a public source London point. Fixed by reading this forum (thanks) and restarting charging via the app.
Really unimpressed by this shoddy Tesla coding. Some people are going to have their journeys badly affected though no fault of their own.

Happened again last night.
I commute 100 miles and my E7 rate only kicks in at 0115 so I have a fairly limited charging window, I really need those 32A
Bloody morons.

I've owned my M3P since March and never experienced this problem but now that I've installed the latest software I've had the charge rate drop a couple of times : https://i.imgur.com/ajIm9mF.png . This is with a BMWi wallbox charger that has worked fine charging various EV's for the last 7 years. This is the first time I've encountered a problem.
Came on here to see if anyone else was experiencing the same issue so interesting to find this thread. Seems I'll just wait for a fix from Tesla, however long that'll take.

Don’t just wait for them to fix it.
If you could please submit a service request, that should spur them into some action. Hopefully it won’t take them a year to fix it like last time...
Just had this back about the charging bug in advance of my service appointment I had booked
Our technicians have reviewed your vehicle intermittently dropping to 17a when charging concern and have confirmed that this is caused by a known firmware bug on current firmware levels. This bug is currently under investigation by our engineering team and fix will be implemented in an upcoming over-the-air firmware update. Until then, whenever this occurs, full charge power should be able to restored by restarting charging.

This is interesting and i suspect behind the charging at 16amps rather than 32, i.e if some maths is one binary digit out then the value is halved in decimal...someone got their maths wrong in a bit of code.
yes actually. When I checked it had tripped. Charging today ok but 17/32 A

If you, or anyone with the same problem, have a data logger such as TeslaFi, could you please check the logs at the time the fault occurred. The pilot current* (ie what the car thinks is the power that the charge point is offering) or charge rate/mi-hr fields might be useful to look at - although I suspect not as things may occur too quick or not at the level reported. * pilot current may be needed to be added to he headers via the edit layout button after you have clicked on the charge icon to show minute by minute stats.
I'm wondering if this is the opposite of the 17A charge problem, that the car is somehow thinking that it should up its charge rate (rather than dropping it to ~17A) and overloading the circuit hence tripping the MCB.
Of course it may show nothing interesting like mine, but I'm only charging at 10A as when I had the issues, I had been earlier topping up on solar.

My car is currently installing 2020.24.6.1. I'll plug it in tonight and see if it has fixed the problem.
