• Weird Engine Sound: The Pentastar 3.6L Jeep engine might sometimes give you some weird rattling engine noise. It happens if your engine is damaged or has a low fuel level. A damaged fuel system or contaminated air can give you the same engine noise for a long time.

• Failure of the Coolant System: Once you’ve completed 120k to 150k miles, you may get the faulty coolant system. In such cases, you get an overheated engine, poor performance, and different engine sounds. If any of these appear after 100k miles, you should check the coolant system thoroughly.
