I took delivery less than 2 weeks ago, 3/25 (I previously wrote 3/24 but I got the date wrong). My VIN is 82XX. I can't check the sticker on the car since it's at the SC right now. It was towed around noon yesterday and as of right now it's still in queue for service.

Mine's in my signature. Delivery mid Feb with vin 50xx. Think the production month was January.
Hardware for sure...Although I suppose if they think software caused it then perhaps they could fix it that way. But the fact that they replaced the HV fuse and rear drive unit seems hardware to me...
Do not underestimate the ability of software to let out the magic smoke in a directly controlled power section (esp if the shoot through timing isn't observed). Likely not what happened here though.

I can’t vote on posts yet, but thanks for linking this thread. It gives a lot of insight on what might’ve happened to my car.
Just got an update from my service advisor. They are indeed replacing the drive unit and fuse, so it'll be at the service center for another few days. I miss my car. 
I used to wake up excited that I got to drive it that day, and I don't even like driving all that much!

The Service Center indicated that the issue revolves around the sensor firmware. In my case, I was backing the car from one driveway to one across the street and I hadn't buckled up. When I shifted from R to D the car's seat weight sensor was ignored and therefore assumed the unbuckled driver wasn't there resulting in an emergency brake being applied. Firmware is going to be adjusted. That's their story and they're sticking to it.

So, if I’m interpreting the posts correctly, if you don’t buckle up even if you move the car a short distance this has the chance of toasting a drive unit by locking the brakes?

Since my incident, I have had zero issues (and zero regrets) with the car. Even the maligned phone-as-key issues have avoided me.

Another BEV enthusiast who owned the same year and model of EV that I did before the TM3 mentioned our VW e-Golf (2015) had a very similar issue with motor-disabled-while-driving that turned into a model-wide recall.

Here is the SC conclusion:
"Reviewed vehicle logs with engineering and found pedal monitor had faulted due to pedal being pressed while customer is attempting to shift. This is a known issue and will be rectified in upcoming firmware update. In the meantime please have customer come to complete stop before shifting, especially due to the steepness of the driveway."
