FCA 3.6L Pentastar V6 Engine Excessive Heat on One Side Class Action

FCA US, LLC makes a 3.6L Pentastar V6 engine that it puts in a number of Chrysler, Dodge, Ram, and Jeep vehicles made between 2014 and 2021. The complaint alleges that the engine is defective, developing heat on one side that causes premature wear to components, and possibly component or engine failure.

The class for this action is all persons in California who bought or leased a 2014 or newer FCA vehicle equipped with a 3.6L Pentastar V6 engine.

The vehicles include the following:

  • 2014-2016 Chrysler Town & Country
  • 2014 Dodge Avenger
  • 2014-2021 Dodge Challenger
  • 2014-2021 Dodge Charger
  • 2014-2021 Dodge Durango
  • 2014-2021 Dodge Grand Caravan
  • 2014-2020 Dodge Journey
  • 2014-2021 Jeep Grand Cherokee
  • 2014-2021 Chrysler 300
  • 2014-2021 Jeep Wrangler
  • 2014-2021 Chrysler 200
  • 2014-2021 Ram 1500
  • 2014-2021 Ram Promaster
  • 2016- 2020 Chrysler Pacifica

The complaint alleges, “FCA sells approximately 2 million vehicles each year. Nearly half of these vehicles are equipped with a Pentastar V6 engine.”

The complaint describes the 3.6L Pentastar V6 engine as “an aluminum dual overhead cam 24-valve gasoline V6 engine, which features variable valve timing” and which “convert[s] energy from the heat of burning gasoline into mechanical work or torque.”

The complaint alleges that the engine “cannot handle the specific thermal demand placed on [it] by the various model vehicles equipped with it.” The complaint claims that the engine has a defect that causes too much heat to build up on one side. This excessive heat keeps the engine parts from being properly lubricated and causes premature wear, notably on the rocker arms, the complaint says.

The rocker arms open and close, allowing fuel to flow into the combustion chamber and exhaust to escape from it. According to the complaint, “[t]he opening and closing of the valves must be properly timed or else the engine will not function properly. Failure in the rocker arms and lifters can throw off this timing, causing loss of power, misfires, or—if left unaddressed—total engine failure.”

The excessive heat in the engine can cause premature wear to the rocker arms and lifters, the complaint claims, “caus[ing] the roller in the center of the rocker arms, which the rocker arms use as a pivot point, to wear out, warp, or to otherwise dislocate the rocker arm.” This can create a ticking sound in the engine. Lifters and valves can also suffer premature wear, the complaint alleges.

Finally, the complaint alleges, the components that suffer the excessive heat can wear down, allowing metal shavings to circulate through the engine. According to the complaint, this can lead to serious engine damage and a need to replace the entire engine.

The complaint alleges that FCA has known about these problems for a long time but has not warned prospective customers about it or found a permanent fix for it. Even when components like rocker arms are replaced, it says, this does not solve the underlying problem.
