2011 335i X-Drive, N55 (running MHD flash if that makes any difference)

I am having a weird issue. Randomly while driving from a stop, the car will jerk, the interior electronics turn off and back on (iDrive, dashboard, etc), and I start receiving DSC/x-drive errors pop up on the screen. This all takes place in 1-2 seconds. Sometimes the electronics do not turn off but the errors pop up.

Other than this, the car drives normally. I can usually clear the codes by turning the wheel all the way in both directions, otherwise it just goes away after the car goes to sleep. It seems to me like the electric is getting disrupted somewhere which is causing the x-drive system to malfunction.

Battery is about 6 months old and was registered upon replacement. Positive and negative wires are tight on the battery. Reading 14+ volts from the posts under the hood when the car is running.

Any ideas on what could be causing this?
