Engine Sludge in Toyota Engines
- The oil inside Toyota's 1997-2005 3.0L engine is predisposed to sludge problems.
- Oil sludge is a thickening of engine oil that increases fricition and heat, eventually causing massive damage to the engine.
- In 2007, Toyota settled a class-action engine sludge lawsuit that covered an estimated 2 to 5 million Toyota and Lexus vehicles made between 1997 and 2002.
While Toyota staunchly maintained that any such "oil-gel" problems are attributable to owners' abuse or poor maintenance habits it did set up a mechanism to reimburse complainants. The language of the settlement appears to include reimbursement to those people who may have already paid to have their sludge damage repaired.
The Engine Sludge Settlement ∞
Toyota settled a class-action engine-sludge suit in 2007 that covered an estimated 2.5-million Toyota and Lexus vehicles made between 1997 and 2002. Toyota agreed to repair the "sludged-up" engines for up to eight years from the time of purchase.
