Re: Cracked head - 2012 v6
Very common for some but usually #2. It has been alleged that there was some faulty machining of heads specifically the valve guides but have not heard of cracked heads before.
Chrysler has replaced a lot of '11, '12, & early '13 heads. I have a lifetime warranty through Chrysler and check about monthly for misfires so am not concerned.
