Toyota Excess Oil Consumption Class Action Lawsuit

Toyota excessive oil consumption class action

This class action alleges that Toyota’s 2AZ-FE engine is defectively designed and/or manufactured and these defects lead to excessive oil consumption.  

Toyota’s 2AZ-FE engine is a 2.4 liter engine that was manufactured by Toyota Motor Manufacturing Kentucky, Inc. at its manufacturing plant in Kentucky. The 2AZ-FE engine is a straight-four piston engine with an aluminum engine block, cast iron cylinder liners and aluminum cylinder heads with dual overhead camshafts.
The following models and model years have the 2Az-FE engine

  • 2007-2011 Toyota Camry HV, 
  • 2007-2009 Toyota Camry, 
  • 2009 Toyota Corolla,
  • 2009 Toyota Matrix,
  • 2006-2008 Toyota RAV4,
  • 2007-2008 Toyota Solara, 
  • 2007-2009 Scion tC, and
  • 2008-2009 Scion xB 

The lawsuit alleges that certain parts of the piston are defectively designed such that excess oil leaks into the combustion engine.

The lawsuit first alleges that the pistons and piston ring assemblies are defectively designed or manufactured and have insufficient tension which can cause engine oil to seep into the combustion chamber.

The lawsuit further alleges that the oil control ring groove and patin drain holes are defectively designed or manufactured  which can cause debris build up that in turn prevents the oil from returning to the oil pan.

The lawsuit alleges that these two design and/or manufacture defects can cause excess oil consumption.
