Wait a minute,
@cwerdna. I'm an engineer. The 12 volt battery problems you reference have nothing to do with the drive motor. There
have been some "accessory" 12 volt batteries failing. The other issues you list are all over the place. Let's be real. There are about a million Teslas on the road. Of course there are going to be failures, like on any electronics. Of course it's always unnerving when it happens to you. Having two DUs fail on the same car might suggest an upstream or mechanical fault causing both. That needs to be thoroughly checked. But statistically it's like rolling dice, each throw is independent of the previous ones.
Reporting a drive failure to NTSB or whoever? sure, if there's a database, why not. Just be specific as to what failed and what was replaced so it's useful.
Now the OP and everybody needs to calm down. People are getting riled up about how he's being charged. That hasn't happened here. The standard Tesla invoice
always shows cost to repair for their internal accounting. The car is under warranty, the drive train I believe for 8 years, there's no way he's going to pay anything, or be blamed for it, unless e.g. he commutes under water.
"I want a call back and someone to describe why the vehicle has had two catastrophic failures." Aside from the regrettable fact that they don't call back much, do you think that somebody making calls in service knows the answer to that question?
Please, relax, there's a good warranty, the cars are overall very reliable. Go pick up the car and talk to the service manager until you're satisfied. Ask if they've examined the car carefully and if they've completely excluded some other failure that would cause 2 drives to go out. Ask him what exactly failed, how, what they've replaced, and what else they've checked to ensure there's no hidden problem. Be polite but tell him how much grief and anxiety this has caused, and ask him if this wouldn't suggest to a reasonable person that they missed something during the first repair, and were being negligent, or that you might prefer a new car?
