Why is my Chrysler 3.6-liter engine making a ticking noise?

I’ve had my Chrysler for a few years now with very few issues, but recently it’s started making a ticking noise. I checked the 3.6L engine, and it seems to be coming from there. Do you know what’s causing the Chrysler 3.6 to make a ticking noise?

**The most common reason for a Chrysler 3.6L engine to make a ticking noise is from the “Pentastar tick”—a loud ticking noise originating from the left side of 3.6-liter Pentastar V6 engines produced between 2011 and early 2013.
The 3.6-liter Pentastar is the flagship V6 engine and is found in various cars, including the Chrysler 300, Dodge Challenger, Charger, Jeep Grand Cherokee, Wrangler, Ram 1500, and Promaster cargo vans.
Chrysler discovered the issue in 2012 after complaints about a ticking noise and the check engine light illuminated. Chrysler found the left cylinder heads on thousands of engines were prone to failure from excessive wear and could lead to misfires.
As a result, Chrysler extended the warranty of 2011-2013 3.6-liter Pentastar V6 engines to cover the left-cylinder head for ten years or 150,000 miles.
While an extended warranty on your vehicle may help cover some costs, having a reliable

policy can help to prevent unexpected expenses from accidents or repairs on the road.
