That is just plain wrong, and you're spreading misinformation. That doesn't help anyone.
When a multiple vehicles experience the same concern or failure, engineering monitors the concern to determine if it's simply a coincidence (large batch of repairs, then nothing) or a pattern failure. Once a trend is identified with a certain percentage of vehicles (very small percentage overall), engineering is required to investigate the concern, determine root cause, and resolve the issue.
In the case of the cam phasers, the phasers and PCM calibration were identified to be the root cause of the concern. All 3.5 GTDI (both standard and high output) built after April 8th 2019 have the revised phasers and new PCM calibration. For vehicles built before April 8th, the dealer will replace the phasers with the updated design and reflash the PCM.
It sucks that anyone needs to have the front of their engine torn down, but there is a solution. If anyone has questions about this please quote my post and I can assist.
