Just an FYI for others to get the word out: 9,000 miles on a 2012 Rubicon and the MIL light came on. Jeep dealer said it was a TSB problem, applied the computer patch fix for something they claimed had to do with the valve timing, reset the code and gave the vehicle back.
The MIL was back on in an hour with the same P0304 code. The mechanic then tried telling us we had bad fuel. Told him we had read web info about people having bad cylinder heads with that code and he denied any knowledge of it. Made it clear we wanted the engine tested for compression, bad valves etc.
The mechanic basically threw his hands up and said he was going to put a "star" request into Chrysler and ask them what they wanted him to do with the vehicle?
The "star" request advised the mechanic to keep the vehicle, remove the intake and inspect the engine. Got word today that the cylinder head is bad.
The dealer states they have to order the parts and have no firm date of when we are getting vehicle back.
Only ray of sunshine in this mess is Chrysler is picking up the tab for a rental vehicle. We don't have an extended warranty or policy that is paying for the rental; Chrysler is doing it on their own, which is good because we are out of state on a vacation.
Again, just getting this out there for others. And you can't tell there is an actual engine problem just by driving the vehicle - at least we couldn't anyway.
I'll post the final outcome about how long it took them to fix it and what they replaced...
