2014 Model S 85 died, unable to start

I was not given any explanation on why DU went bad. After DU replacement, i am still fighting nasty knock from rear during acceleration (4 visits to SC later they still can’t find a source). Considering taking car to @wk057 for diagnostic as i am running out of options 😕

Rear subframe?

Do they acknowledge there is a knock?

Rear subframe - i asked them to check specifically that, 4 times - they said it is ok. I went under the car and carefully checked all contact points/joints at the subframe- no cracks.
And yes, they acknowledged the knock.
