What is the class action lawsuit for the 3.6 Pentastar?

Owners of vehicles equipped with the 3.6L Pentastar engine manufactured by Chrysler have filed a class action lawsuit alleging defects in the engine design that can lead to premature failure. The lawsuit seeks compensation for affected vehicle owners and demands that Chrysler address the underlying issues with the engine.


What is the 3.6L Pentastar Engine?


The 3.6L Pentastar engine is a V6 engine developed by Chrysler and introduced in 2010. It has been used in a wide range of Chrysler, Dodge, Jeep, and Ram vehicles, including the Chrysler 200 and 300, Dodge Challenger and Charger, Jeep Wrangler and Grand Cherokee, and Ram 1500 pickup trucks. The Pentastar engine was designed to be a more fuel-efficient and powerful alternative to Chrysler's previous V6 offerings.


The Class Action Lawsuit


The class action lawsuit alleges that the 3.6L Pentastar engine is prone to premature failure, with issues such as excessive oil consumption, engine knocking, and complete engine failure. The lawsuit claims that Chrysler was aware of these defects but failed to properly address them, leaving vehicle owners to bear the cost of expensive repairs.


Key Allegations in the Lawsuit



  • Excessive Oil Consumption: The lawsuit alleges that the Pentastar engine can consume oil at an abnormally high rate, leading to the need for frequent oil changes and top-ups.

  • Engine Knocking: Some owners have reported experiencing engine knocking or tapping noises, which can be an indicator of internal engine problems.

  • Engine Failure: In severe cases, the lawsuit claims that the Pentastar engine can experience complete failure, requiring a costly engine replacement.

  • Chrysler's Awareness: The lawsuit alleges that Chrysler was aware of these issues but failed to properly address them or provide adequate compensation to affected vehicle owners.


The class action lawsuit seeks to hold Chrysler accountable for the alleged defects in the 3.6L Pentastar engine and to provide compensation to affected vehicle owners for the cost of repairs and other damages.


Potential Outcomes


If successful, the class action lawsuit could result in Chrysler being required to cover the cost of repairs for affected vehicles, provide extended warranties, or even issue a recall for the 3.6L Pentastar engine. The lawsuit could also lead to monetary compensation for vehicle owners who have already incurred expenses due to the alleged engine defects.
