Chrysler to extend warranty on 3.6-liter V6 Pentastar engines built between 2011 and 2013

Article by Christian A., on June 17, 2014

Chrysler Group plans to extend the warranty for customers who purchased some MY2011-2013 vehicles fitted with 3.6-liter V-6 Pentastar engine after finding out that a small number of the powerplants had cracked left cylinder heads. The engine warranty on the left side cylinder head now covers 10 years or 150,000 miles.

The other components will be covered by a 5-year/100,000-mile powertrain warranty. In 2012, Chrysler executives remarked that around 7,500 engines were prone to the cylinder head failure. Chrysler discovered the issue in 2012 following customer complaints on new vehicles having a "ticking sound" or stalling, and a check engine light illuminated.

Doug Betts, head of quality for Chrysler, quipped to Automotive News that year that the issue was discovered in about half of 1 percent of vehicles equipped with the Pentastar engine. Chrysler did not disclose whether the figure has since changed. The 3.6-liter V-6 Pentastar is the Chrysler’s primary V-6 powerplant.

It comes as standard in a number of Chrysler’s its top-selling vehicles like the Jeep Wrangler and Grand Cherokee. Chrysler probed into the issue for months and attributed it to an unusual mix of factors including low-quality fuel and certain driving conditions.

Chrysler said in a statement that the engines may be susceptible to an engine misfire caused by a combination of “rarely occurring factors, including drive cycle and fuel quality." The carmaker noted that the problem does not disable the engine.

To fix it, dealers will replace the left cylinder head with a new part with a modified design. According to Chrysler, it modified the design in August 2012, after which the carmaker had not received any complaints regarding the problem.
