Chrysler is extending the warranty on one of its most popular engines.

The American automaker has announced that certain 2011-2013 model year vehicles will get warranty extensions because the left cylinder heads might crack. Chrysler will extend the engine warranty on the left-side cylinder head to 10 years or 150,000 miles and the remaining engine components will continue to be covered by the standard five-year, 100,000-mile powertrain warranty. According to Chrysler, roughly 7,500 engines were susceptible to the cylinder head failure and was first discovered in 2012.

According to Doug Betts, head of quality for Chrysler, the problem has been found in about 0.5 percent of vehicles with the Pentastar V6 engine. The Pentastar V6 is used in a variety of models including the Jeep Wrangler and Jeep Grand Cherokee.

“A small percentage of these 2011-2013 model year engines may be susceptible to an engine misfire which is caused by a combination of rarely occurring factors, including drive cycle and fuel quality,” Chrysler said in statement. “The issue does not disable the engine. Dealers will replace the left cylinder head with a new part with a minor design modification.”
