NHTSA Complaint #11513568 — 2018 FORD EXPEDITION

I own a 2018 Ford Expedition 3.5L ecoboost. This is an engine and vehicle that is known to be problematic. In 2020 I took my vehicle to the dealership to have the noisy cam phasers fixed, a TSB was found and the parts HL3Z cam phasers were replaced under the powertrain warranty. Now in September of 2022 my vehicle started having issues again with the same problem, since Ford told me that the problem was only noisy and not a mechanical issue I delayed taking it to the dealership until it started having more issues with idle, power, etc. It is then that I find out there was actually an extended warranty/ recall for that issue. Ford is denying my claims saying that my problem was fixed in 2020. The parts it was fixed with are faulty, and redesigned parts were released in late 2020 that have a stiffer spring that allows the oil pressure to hold better than the HL3Z cam phasers, thus preventing the problem. The new parts the ML3C cam phasers are now what Ford is telling me need to be replaced at a $3000 charge, in addition to the timing chain which has been damaged due to the cam phaser issue. Ford needs a recall on vehicles with the faulty HL3Z 6C525 cams not just a vin recall. This is a KNOWN problem for this engine and Ford is doing everything they can to avoid paying for their mistake.
