moved due to me posting in wrong section...

1st a warentee issue , I would think that a heater hose , would be quick and easy , could also be a freeze plug .
Have you check the res. & rad. levels , keeped topped off , but get to dealer and get fixed on warentee .

you might get more replies if you had this thread in the 03-07 instead of 07 and up.

OOps I will have to move this, sorry
