- NHTSA id: 10083420

## NHTSA's summary

IF AN INTAKE ROCKER FAILS ON A VEHICLE BUILT FROM APRIL 2013 TO AUGUST 2013, ALL SIX INTAKE ROCKERS MUST BE REPLACED ALONG WITH THE FAILED CAMSHAFT. INVESTIGATION HAS FOUND THAT POOR ADHESION OF THE PVD COATING USED ON THE ROLLER PIN WAS THE ROOT CAUSE OF THE FAILURE. THIS LEADS TO A HIGHER FRICTION SLIDING SURFACE AND THE COATING PARTICLES GETTING TRAPPED BETWEEN THE ROLLER AND PIN CAUSING THE ROLLER TO SKID OR LOCK UP.
