We have the same issue. But, we have two homes where we charge the Tesla and both are set up differently. We have a Nema 14-50 with an extension cord at one house, and a Nema 14-50 with the Juicebox at our other home. The car has the same issue at either location. The car will charge, stop, charge, and I will get five messages from the Tesla app telling me the time and percent/mileage that the car is at.
I have to restart the charge from the app on occasion, or go out to the car and try to get it to charge again. This is for a Sept 2022 build.
We have another car that we plug in, so we didn't want to go with the hardwired Tesla unit.
