2018 Ford F-150: check engine light

Filed Oct 19, 2026 · Fuel system · TX

Mandatory recall 24E12 reprogrammed the Powertrain Control Module (PCM) to stricter emissions monitoring standards. This caused the Check Engine light to appear within 24hrs showing code P0430. There were NO codes showing and the Check Engine light was not on before the recall was performed. Ford is denying responsibility and charging me $2,500+ out of pocket to replace the converter. I feel like they a FORCING me to purchase parts because if I don't, my vehicle wont pass emissions tests and is un-drivable (legally). Ford case#: CXH0966043220H4B3 Apparently, this has happened to THOUSANDS of F150 owners and needs to be addressed ASAP!!!!!

My truck has the 3.5 ecoBoost twin turbo engine with the known cam phaser problem. Ford dealership replaced cam phasers 4 years ago and told they were putting in new designed cam phasers to prevent this from happening again. Last week, I changed the v v t cylinder because of a p0018 code, and found that the replacement was the old cam phasers prone to break again. Truck is just now out of warranty. And ford is doing nothing to help. Drivability is not the same has hesitation. So far, and I'm sure it's going to get worse. Check engine light just went on last week. This truck is at dealership now. My biggest problem with this situation is Ford. Dealer lied said they put in new cam phasers, which they put in old ones. I would have got an extended warranty if I knew they were the old cam phaser. Now, I will be out 3 to 5 thousand dollars because ford dealership lied to me. I have all paperwork. Service reports everything on the truck. The truck was babied. There's no reason why in 70000 miles catastrophic engine failure twice. Fixing the problem with the same problem. Parts is not a fix. It's a bandade until warranties are over. And let the people deal with it.

2018 Ford F-150 Limited with the 3.5L EcoBoost engine. At approximately 60,000 miles the engine began making a rattling noise from the front of the engine on cold start, lasting several seconds. Over the last three months the noise has become progressively worse and now occurs at every cold start and lasts longer. The check engine light is currently illuminated. The vehicle has not stalled or lost power. A Ford dealer (Wynne Ford, Hampton, VA) diagnosed the condition on September 24, 2026 at 104,661 miles as cam phaser failure, requiring replacement of the variable camshaft timing (VCT) units and associated timing components. This matches Ford's Technical Service Bulletin 23-2143, which covers 2017-2020 F-150 vehicles with the 3.5L EcoBoost engine built on or before November 30, 2019. Ford previously issued Customer Satisfaction Program 21B10 and warranty extension 21N03 for this same defect on March 2, 2021, but 21N03 expressly excluded the F-150 Limited trim, and both programs have since expired. The dealer additionally reported that it has submitted multiple other cam phaser repairs on 2017-2020 3.5L EcoBoost vehicles for manufacturer assistance in the past two months, including vehicles newer and with lower mileage than mine, and that all were denied. The quoted repair is $5,414.11 at my expense. I am filing this report because cam phaser failure in these engines can progress to timing chain damage and engine failure, and because Ford has documented this defect since at least 2021 without issuing a recall. I contacted Ford (case CXH-09424982) and was denied any financial assistance.

I was required to complete the recall 24E12 on my 2018 ford F 150 2.7L eco boost XLT. Upon completion the check engine light comes on. I looked into this and this is an ongoing problem with the emissions recall . I scanned for a code and P0430 is coming up. (Catalyst System). I contacted the dealership and ford corporate and they will not help assist in resolving this issue. I explained my vehicle was working fine until the mandatory emissions recall was completed and that under the good will assistance I should be covered for Some compensation fixing this vehicle. I was denied any additional help. I as a loyal customer for many years don’t believe that it is my responsibility to pay a full bill for a new converter when it was their recall that caused the issue on an already perfectly fine vehicle.

10r80 transmission CDF Failure. Had repair completed though still has issues with 4/5th gear. Truck will lose power while accelerating until it finds the gear it wants to go. Multiple re-learning processes completed with no solution. V6 ecoboost - cam phasers repaired twice. 1st time by initial owner but that was not relayed to me. 2nd time by me after multiple trips to the dealership where they couldn't reproduce the issue. Took videos and finally brought the truck in with the check engine light flashing. Required entire engine rebuild.
