Has anyone else had to have the entire head replaced? I smell recall.

"Did anyone notice a decrease in gas mileage prior to the full onset of this issue? My mileage has been terrible lately. I recently has an ignition coil replaced which smioothed my idling but no change in the mileage. I wonder if this sudden drop in mileage is a sign of bigger things to come..."

Took mine to the dealer today because my gas mileage was about 13mpg on average and my engine light came on for a little bit over the weekend. I'm in a rental and they said they are going to replace the head I have about 25,000 miles on it
