## NHTSA's summary

ENGINE ASSY \- 3.6L AUTO TRANS Before replacing the engine due to an abnormal ticking noise, please check that the INTAKE Hydraulic Lash Adjusters are not "collapsed". If a collapsed INTAKE HLA is found, replace all INTAKE HLAs on the suspect cylinder head. The noise can occur at low or high RPMs, and at low or high temperatures. There are no Diagnostic Trouble Codes \(DTC\)s present. CAUSE: INTAKE Hydraulic Lash Adjuster may have a manufacturing issue that can cause the plunger to stick, generating valvetrain noise.
