Driveshaft problems of the 2016 Volkswagen Jetta

This car continues to sporadically go in reverse while I am in drive. This has happened while waiting in like at a drive through, foot on break while in drive while waiting for food, then told to pull up only to nearly back into the car in line behind me. Had to put car in park and shut off engine- restart to correct problem. Has happened while foot on break at red light while in drive, took foot off break when light turned green - car went into reverse while drive shaft "d" still lit up almost backing into car behind me. And again this happened while backing up in my apartment parking lot, put car into reverse to back out, break, when to put car into drive and car went into reverse. Each time the car has went into reverse while in drive I have had to turn off the car completely and restart to correct the problem. This is a huge safety hazard and threatening to my car, my safety, and other drivers. Dealership cannot recreate problem and says therefore there is no problem, vw customer care is no help either as they simply keep telling me to take it back to the dealership.
