This vehicle has an oil consumption problem the same as other Toyota vehicles in the class action lawsuit relating to owners having to constantly spend money on oil due to a defect in the engine. This Toyota/Lexus engine defect consumes oil and this problem grows worst as the vehicles get older. Toyota knew of this Issue but did not inform customers, and will not help in the repair or do a recall. This problem can cause the engine to fail and cause a host of other Issues.
