Last week we mentioned that older Lexus hybrids, including the GS 450h and LS 600h L, were potentially impacted by a bad valve spring issue which, in very rare cases, could cause the engine to stop while the vehicle is in operation. The luxury Toyota brand has now turned this issue into a full fledged recall.
Lexus said it will be recalling overall 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. This includes 2007 and 2008 GS 450h hybrid models as well as the 2008 LS 600h L year. It is said that due to slight variations during the manufacturing process, some foreign material may have contaminated a small number of the valve springs. In most cases where anything at all happens, only abnormal engine noise or idling may occur. It would be very rare indeed for the engine stoppage potential to occur.
Lexus plans to contact owners of the impacted vehicles via a letter. Lexus dealerships will handle the free repairs for those notified. 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.
