2016 Tesla S suddenly lost power (PRND turned RED). No error message!

2016 Tesla S
I had no issue with my car until after low voltage battery was replaced by Tesla Mobile Support 10 days ago.
A few days later, I noticed a noise coming from the frunk area. The noise was more noticeable on low speed drive. The noise gradually became louder then today suddenly lost power while driving on a highway. I noticed PRND turned RED. Never seen this before. No error message on the dashboard. The power came back in a few seconds later. I was able to drive home without another episode until I almost arrived at my house when the car kept losing power. I would put in D then step on gas, but immediately lost power. This kept happening for several minutes and I was not able to park in the garage. About 10 minutes later the power stayed on long enough to pull into my driveway. I requested Service, but the earliest date is 1 month away! Any feedback would be helpful, since I can't find any similar issues. Thank you in advance.

Can you go into Service mode and see what errors there are?
Or better yet, post pics of your error messages

Could it be the dreaded RDU (rear drive unit) failure? Although I thought that was accompanied by a message. More common in 2015 and older, from what I've read.

My guess was also a DU failure, but only OP can determine that. Definitely need to see error messages else it’s pure guesswork.

The lack of error message could indicate a mechanical failure the software isn't monitoring for, like a broken CV axle. It's hard to say without a description of what the noise sounded like. This kind of reminds me of the time I spun a bearing in my WRX and shot a rod through the block - the failure didn't trigger a check engine light.
