Two problems related to engine burning oil have been reported for the 2008 Lexus IS. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2008 Lexus IS based on all problems reported for the 2008 IS.
The car has extremely high oil consumption. The cylinder walls have apparently prematurely worn down despite timely oil changes and maintenance. I am having to put 2 quarts of oil for every 1,000 miles at this point.
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.
