Service bulletin M110413

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Service Action: N14 Engine Check Timing Chain Tensioner and Timing Chain. The timing chain tensioner applies pre-tension to the timing chain guide rail mechanism. In some cases, the tensioner spring force may be too low. Depending on the severity of the wear, it may lead to a rattling noise when starting the engine cold or when the engine is idling. CAUSE The timing chain tensioner internal tolerances are not consistent.
