In terms of eligibility, the carmaker offers free of cost repairs and the extended warranty only on vehicles from the 2011, 2012 and 2013 model years. Some of the vehicles that are powered by the 3.6-liter Pentastar V6 are the Ram 1500 pickup truck, Jeep Grand Cherokee and Wrangler, Chrysler's 200, 300 and Town & Country models, as well as lots of Dodge-branded cars such as the Challenger, Charger, Journey, Durango and Grand Caravan.
Chrysler explains that it won't issue a formal call back operation to fix this glitch because if the cracks are to occur, the engine will still work in a rough, misfiery manner. Dealership service department will fix cracked left cylinder heads by replacing them with a newly developed component. Other engine components which may not operate properly will be replaced as well, with Chrysler offering a 5-year/100,000-mile warranty for them.
As a brief reminder, the Chrysler Group found out about this fault a couple of years ago after several customers complained that their all-new sub 1,000-mile vehicles were producing an intrusive "ticking sound" at idle.
