Was going to drive my daughter to school this morning only to find my 2018 Model 3 COMPLETELY dead and unresponsive. The car was plugged into the wall charger overnight. Couldn't unplug either.
Contacted Tesla roadside assistance. They called a tow truck to have my car towed to the local service center.
Tow truck showed up, but since the car was in my very tight 1-car garage front end first, we had to figure out how to get it out of the garage. We got the plug removed from the front bumper, took a while but we eventually fished out the wires to open the frunk. We used his portable jumping device, nothing, frunk didn't open. He then moved his tow truck closer and use the extra long jumper cables and hooked those up to the wires, the frunk opened right up. We then got to the 12V batter and hooked up to those. Nothing. I contact Tesla and they said give it 20 min. We left it hooked up 30 min, still nothing. No response whatsoever. The tow truck driver said he's seen this happen before and that a Tesla tech neede to fix it. He then said he couldn't do anything more and had to go.
Tesla rep then arranged for a Tesla tech to come by. He checked everything and also stumped that the car was completely unresponsive to jumper cables attached to the 12V battery. He brought a spare 12V battery, so he swapped it out and as soon as he connected it, the car came back to life!!!!
He contacted a senior rep who went through the car's logs and said that just before the car died around 4am it was drawing about 3A from the 12V battery and that at some point the car shut itself down.
The car was plugged into the Tesla wall charger overnight and it DID charge the car yet the 12V battery died.
After a bunch more reviewing of logs they think it might be the Hannshow 9" display that for some reason could have been drawing power. The Hannshow display had been installed for almost a month now and I never had any problems before. The car never reported a problem with the 12V battery.
So, we're stumped. I disconnected the Hannshow display as a precaution, but I'm not sure that's the problem.
Anyone ever experience something like this?
