Indeed, call Subaru Road Assistance (or whatever they call the "free" towing service that should have come with the new car). Have it brought to the dealer. But before loading the car on the flatbed, show the driver what is happening and even have them try it (in addition to perhaps videoing); it will help to have a "witness", especially one who is going to be paid to bring the car in on Subaru's tab. And don't do anything in the meantime that might clear the problem.
