Home charging being throttled with latest software update

[vogz]

Updated my car (to 2021.36.5.5) and the mobile app (to 4.2.2 on iOS) the other day and noticed the next time I plugged into my wall connector, it was only charging @ 14 amps (4kW). I manually turned it up to 48amps and it charged the rest of the way with no issue. Again today I plugged the car in and it's charging at 14amps again. I again manually turned it up to 48amps and it increased charging speed again. I let it charge for about 5 minutes and unplugged it for about 30 seconds and plugged it back in. Now it only went to 47amps and I had to click it up that one more amp. Does anyone know why this might be happening? I'm running on a 60amp circuit with 6 gauge wire and never had any issues like this until the most recent update.

You haven't mentioned this yet, but are you adjusting the amps through the mobile app on your phone, or using the touch screen in the car? I saw another thread where @SabrToothSqrl has found that this new software version broke that if you try to change it in the app. His current keeps getting dropped from 32 to 31.

amps cuts to 31 now...

So... as far as I know my amps have been 32 since new. never had an issue that I know of. Now the app, which shows and lets you change charge rate.... when I open it at random shows 31. wtf? i set it to 32 and randomly (almost every time actually) it's showing 31... why?!?! 32 is slow enough. I...

I was using the mobile app to turn it back up since it's easier than going into the car to do it. If it's turned back down tomorrow again, I'll try turning it back up in the car and report back. Seems like it's probably a software bug.

well, at least I'm not the only one. Service brushed it off as 'customer is an idiot'. I mean 'customer education'. BS.

Pretty much the same experience here when changing via the app. I had to goto the car and change there.

So seems like it's an issue with the mobile app.

So I set it back to 48amps inside the car and it's now charging at 48amp on the subsequent charge with zero issues. Definitely a mobile app issue.
