Recall 10V309 covers 138,874 2006-2008 Lexus passenger cars for engine valve springs that can break. Repair is free at any franchised Lexus dealer.
Lexus is recalling 138,874 2006-2008 passenger cars, including the LS600HL, GS450H, and LS460, because micro-foreign objects in valve spring material can weaken the spring and let it break. A broken valve spring can make the engine fail and stop suddenly while the vehicle is moving, increasing crash risk, and the dealer repair will be free once available.

What's wrong?
The valve spring in the 2006-2008 Lexus LS600HL, GS450H, Is 350, Gs 350, LS460L, LS460, and GS460 engine is a small metal spring in the cylinder head. Its job is to pull an engine valve closed after the camshaft opens it, so air and fuel move through the engine at the right time and pressure stays where it belongs.
In this recall, micro-foreign objects in the spring material degrade the strength of the spring. That weakened spring can break during normal engine operation. Once it breaks, the valve no longer opens and closes as designed, and the engine cannot manage that cylinder correctly.
There is no warning sign before failure. If the spring breaks, the first thing an owner notices is the engine problem itself, so the recall repair matters even if the car has sounded and driven normally.
