There has been issues of the gasket behind the water pump going bad and as for putting pellets is not a fix to the issue, it's just a band aide to mask the problem that will bite you after the warranty is up.

Take it back and have them flush the pellet out of your system before it plugs up other area's like your heater core and water jackets through out your engine which will restrict the coolant flow.

Lastly take it to another dealer, never take my toys to a butcher of cars and truck.

Good luck and keep us posted.
