Transmission going to neutral

Hi everyone, I have had two episodes over the past month or so where my transmission went into neutral on its own. First time was when I was creeping forward to park in my garage, and the other occurred as I was nearly stopped for a stop sign. Both times I was hardly moving. Car went back into drive right away once I realized I was in neutral and put it back into drive. Anyone else have this kind of issue or know if it’s a sign of a major issue? Car is a 2021 with only 18k miles on it. Not abused nor tuned.
thanks for any input!

This means network disruption. Couple modules are interacting poorly to request attention...

You should get your chassis scanned by a MB Specialist or buy a LAUNCH Elite MB scanner for less than half diagnostic price.

Let us know the fault description shown in your scan. This is unlikely major unless chassis gets in a traffic wreck.

Get a transmission fluid change first, IF that doesn't work, then it will likely be a busted valvebody. Same thing happened to my C43 but at 63,0000 miles. After getting the valvebody replaced, get a full trans fluid flush or else you might have issues with shifting 1-2-3-4 after..
