The National Highway Traffic Safety Administration has been informed by Lexus of its intent to file a Defect Information Report (DIR) that covers about 138,000 Lexus vehicles. The formal report is expected to be filed sometime this week.
The division of Toyota Motor Sales, USA, Inc. said that these vehicles are equipped 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 US.
Lexus said that because of slight variations in the manufacturing process, some valve springs may have been contaminated by foreign material.
There’s a slight possibility that an affected vehicle will exhibit abnormal engine noise or idling. In the worst cases, the engine could stop while the vehicle is being operated. Lexus estimates that the chance of a vehicle having this condition is 0.2 %.
To date, Lexus has gotten no reports of accidents or injuries linked to this matter. Lexus would also like to clarify that vehicles from 2009 and from the current 2010 model year are not affected.
Owners of the affected vehicles will receive a recall notification via first class mail. They are asked to contact their local Lexus dealer for diagnosis and repair, which will involve replacement of the engine’s valve springs at no charge.
