DETROIT (June 16, 2014) — Chrysler Group L.L.C. will extend the warranty for consumers who bought certain 2011-13 vehicles with 3.6-liter V-6 Pentastar engines.
The left cylinder heads of a small percentage of the engines have cracked.
The company will extend its engine warranty on the left side cylinder head to 10 years or 150,000 miles. The remaining engine components will continue to be covered by the auto maker's 5-year/100,000-mile powertrain warranty.
In 2012, about the time Chrysler was instituting its design change, executives said that roughly 7,500 engines were susceptible to the cylinder head failure. A spokeswoman for the company last week declined to say whether that estimate is still valid.
