Cam Phasers. Ford refuses to repair cam phasers despite having a recall previously and never fixed by previous owner. Ford quoted the repair at $8k. Previously recall stated safety concerns over faulty manufacturing of cam phasers, having plastic parts and exposed parts rather than metal and enclosed parts like in they install during the repair. While I understand the repair was a voluntary recall, it's still a safety concern as engine has rough idle, rough shift changes, sometimes will jolt forward while idling and possible engine shut off due to damage to camshaft caused by the failing cam Phasers. This should be an the federal safety agency ordered recall.

CAM PHASERS!!!! I have a 2019 Ford F-150 with the 3.5L EcoBoost engine which started having cam phaser issues. On cold starts, the engine makes a loud rattling noise for several seconds, and during idle a ticking noise is heard as well. At times the engine runs roughly and loses power briefly when i’m driving it. I’m very concerned because it happened to me while merging into a highway the truck cut power down and I almost caused an accident for not getting up to speed properly, additionally this could lead to the car shutting off on me, or other dangerous situations on the road, other than the long wear and tear that these bad cam phasers have on the engine. I’ve learned that this issue is known to Ford and has been happening for many years, and was addressed for other owners through Customer Satisfaction Programs like the 21N03 and its various supplements, to my knowledge the last one being held in 2022, but my truck is not covered at this time even though it’s a 2019 and has under 70,000 miles. I believe this issue should be investigated further as it is a safety risk to drivers, passengers, and all other vehicles on the road, and Ford should be held accountable, as this issue has been seen around their 3.5 Ecoboost engines and has yet to be fixed. It seems like it’s an ongoing profitable business for them to keep customers paying out of pocket for this $4,000+ job knowing that it’s an issue that many owners have, which is beyond ridiculous on their end. If it’s possible for you guys to take a look at any of their social media platforms, most of the comments on their posts, even if they have nothing to do with this engine, are complaints about not having a Recall for cam phasers on the 3.5 Ecoboost engine. Ford needs to be held accountable for this issue and give more importance to the safety of their customers instead of their parts/service profits!!!!!!
