According to Automotive News, approximately 7500 Pentastar engines built for the Wrangler in early 2012 were found to be susceptible to left-cylinder head cracks, potentially resulting in engine failure. Chrysler first discovered the issue when customers began complaining that their vehicles were making ticking noises, stalling, or that the instrument panel was inexplicably displaying a check engine light.
Currently Wranglers come with a 5 year 100,000 mile warranty, in this case the warranty is being extended to 10 year 150,000 miles. The cracked head is said to only show in a small percentage of Jeeps and a late 2012 design change remedied the issue.
jeepfan.com note: The 2012 jeepfan.com Wrangler is an early 2012 Jeep and was affected with this cylinder head issue. The dealer where the Jeep was purchased replaced the cylinder head and no further issues have been experienced.
