Not sure if this is an issue, and if there's some known fix:

When i go to accelerate, at times there will be a delay, with a major engine rev up to 5000 RPM, and then it will accelerate.

Doesn't happen all the time but i've noticed this pretty much since i bought the Jeep - but couldn't reproduce for the mechanic.

Thoughts?

Do the dealerships fix the Service Bulletins for free? How does that work?

 

Depends on dealership. Some will and some just tell you they don't mean nothing and your outta luck

Is a service bulletin and the thing from the NTSB different things? I have problems with mine cranking and dealer said they have a service bulletin that came out when it was built, but it would cost me about a $1,000.00 , I'm living with it

Does anyone know of a TSB for the 2012 cylinder head problems?

 

I just looked at AllData, which is usually up to date on recalls and TSBs. Didn't find anything on the subject.

there is no specific tab. They recently sent a letter to the owners of the effected vehicles which indicates coverage for 150k or a given time. They won't repair/replace anything until it throws a code.
