Please do not spread speculation and misinformation. The camshaft phase issue was isolated to the phasers themselves not parking properly. The production cutoff occurred in April 2019 and service parts have the upgraded design. There were no “multiple” releases of “updated” parts as you speak of. I have explained this in other threads. The phasers fail to lock upon shutdown, which causes erratic operation (rattle) on the next start, because cam timing will be unstable until full oil pressure reaches the phasers. A phaser with this failure mode is easy to identify upon tear down; the camshaft can be moved throughout the phaser’s range of travel with the phaser unit moving. A single example of vehicle exhibiting a similar, possibility unrelated noise at extremely low mileage is not an indication that the issue in question has not been resolved.
