TORRANCE, CA - Lexus discovered faulty valve springs in some V-8 and V-6 engines in certain Lexus models sold in the U.S. Due to slight variations during the manufacturing process, some foreign material may have contaminated the valve springs resulting in potential breakage. 

In such a situation, 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 has not received any reports of accidents or injuries related to this issue.

Approximately 137,000 vehicles are potentially affected in the U.S., including the IS 350, GS 350, GS 460, GS 450h, LS 460, LS 600h L.

Current model years are not affected.

Lexus is moving quickly to resolve the situation and will announce an appropriate remedy as soon as possible.  

"In the meantime, we sincerely apologize to our customers for any inconvenience and request that they contact their nearest Lexus dealer if they believe there is a problem with their vehicle," said Mark Templin, group vice president and general manager of the U.S. Lexus Division.
