TORRANCE, Calif. - Lexus, a division of Toyota Motor Sales, USA, Inc., today announced that it has informed the National Highway Traffic Safety Administration of its intention to file a Defect Information Report (DIR) regarding approximately 138,000 Lexus vehicles, powered by 4.6 and 5.0 liter V8 and 3.5 liter V6 engines in certain 2006, 2007 and 2008 GS, IS and LS models in the U.S. The formal report will be filed the week of July 5.

In the covered vehicles, due to slight variations during the manufacturing process, some foreign material may have contaminated a small number of the valve springs. If a vehicle is affected, there is a remote possibility that abnormal engine noise or idling may occur. In extremely rare instances, the engine may stop while the vehicle is in operation.

Lexus estimates that the likelihood of a customer vehicle experiencing this condition is two-tenths of one percent (0.2 %). Lexus has received no reports of accidents or injuries related to this condition. No vehicles from the current 2010 model year nor 2009 are affected.

Lexus will send owners of the involved vehicles a recall notification via first class mail. Owners are requested to contact their local Lexus dealer for diagnosis and repair after receiving their notification. The repair will involve replacement of the engine’s valve springs at no charge.

Owners can continue to drive their vehicles. If symptoms are noticed, such as vibration, rough idling, unusual engine sounds or poor performance, the vehicle should be brought to a Lexus dealer for service.
