2018 Ford F-150 fuel system problems

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!!!!!

The 10-speed automatic transmission (10R80) shifts harshly and erratically, hangs in gear, and lost 2nd gear entirely, causing unpredictable acceleration and gear engagement in traffic. First reported to a Ford dealer on 6/8/2021 at 25,883 miles (dealer called it normal). Repairs: internal teardown at 32,920 miles (damaged clutch, input shaft, torque converter hub); valve body repair under TSB 24-2101 at 63,483 miles; CDF hub and friction plate failure diagnosed at 77,584 miles (TSB 25-2126 failure mode); loss of 2nd gear at 88,449 miles. Pre-repair scan 9/2026 shows P0732, P076F, P07F6 (incorrect gear ratio, gears 2, 7, 9). Transmission being rebuilt again 9/2026. The engine also suffered timing chain and crankshaft failures requiring a full engine replacement at 66,108 miles and another timing repair at 77,584 miles. Three catalytic converter failures. Nearly 200 days in Ford dealer service departments.

The engine dies out then on then out during any speed. Will not accelerate, Will not start. Dies out on the interstate and in town. Each repair by the dealer has not fixed my truck. I see Ford has recalled this model of F150’s but not mine. It needs to be.

This vehicle received a PCM update performed in strict accordance with Ford service procedures, per TSB/SSMO No. 24E12, on 1/02/26. At the time of the update, no stored or pending diagnostic trouble codes related to catalyst efficiency were present, and the vehicle was operating as designed. Pre- and post-update scan data has been retained and is available upon request. Approximately 100 miles after the recalibration, the check engine light illuminated. The vehicle was returned for service within 500 miles, at which point a DTC P0420 (Catalyst System Efficiency Below Threshold) was confirmed as a mature two-trip fault. This condition was not present — and had not been detected — during the vehicle's prior 134088 miles of operation, which includes no history of catalyst-related codes. The immediate onset of this fault following the PCM recalibration strongly indicates that the updated calibration altered system monitoring thresholds in a manner that directly triggered this code. This presentation is inconsistent with an ordinary mechanical failure. The most reasonable conclusion is that the fault is either calibration-induced or that the prior calibration's monitoring parameters were insufficient to detect a borderline condition that the updated calibration now flags. In either case, the root cause is directly traceable to a Ford-mandated software update — not to customer neglect, abuse, or normal wear.

Manufacturer recall #24E12 (PCM software update) triggered a PO430:00-ED code (Catalyst System Efficiency Below Threshold - Bank 2) because the new software more strictly monitors the catalytic converter, causing it to detect previously ignored degradation. This reprogram scamming program makes community bothered by paying parts replacements more than 2K, even vehicle was fine before the recall. This needs resolved with FREE FIXED and FREE Catalytic Replacement. This is not right to announce a recall with unfinished repair issues left. This needs action. Thanks, So mote it be!

I own a 2018 Ford F-150, with the Cougar V-8 and a turbocharger. A few years ago, while on the expressway, I had to accelerate to clear a dangerous situation. A message came up on the instrument cluster saying that I was seriously low on oil. I pulled off on the shoulder and shut the engine off. I checked the oil level and it was almost empty. The truck only had about 10,000 miles on it at the time. I had checked the level prior to leaving and it was full. Luckily, I carry extra oil on long trips, a habit I got into back when I used to drive beaters. I had enough oil to fill the engine back up with oil and proceed on my way. I have not had any oil loss since then, although I rarely drive the truck, except to pick up lumber or other large loads, and it currently has about 23,000 miles on it. A few years ago, I read about an F-150 whose driver tried to pass a slow moving vehicle on a mountain road and was hit by an oncoming vehicle. Everyone in the truck was killed. When I read that article, I thought back to what happened to me. Luckily, I had room to pull over. I believe that when I did that hard acceleration (as the driver on the mountain road must have done), a large amount of engine oil must have been sucked out through the turbocharger, emptying the crankcase. If this happened to the driver in the article, he would have been left with no engine power and no way to complete the passing maneuver. This is all speculation on my part, but an emergency hard acceleration should not empty any engine of oil, leaving the vehicle's driver and their passengers defenseless.

I was not in an accident. I have a 2018 ford f150 xlt and it has a 3.5 eco boost. My truck is leaking some type of oil from the top and has very bad fuel injectors which is why my truck cant accelerate and shakes extremely bad. When I sit at a red light my truck dies and I think i have a leaking exhaust. I bought a new battery but it still dies. I know they used to do a recall for a new engine from what i’ve searched but they don’t do it anymore and I don't think its safe for me driving while I have all those problems. I have not been in an accident but with all these problems my truck could possibly die or go out while i’m on the highway and just makes me nervous driving something like that when the 3.5 eco boost is already not a great engine. Thank you

The vehicle experienced repeated failures involving multiple systems, including the transmission system (transmission replacement), powertrain/engine system (cylinder-related repairs), electronic control systems (vehicle computer/control module replaced multiple times), electrical system (ongoing electrical faults), and rear safety systems (backup camera failure). The vehicle is available for inspection upon request. These failures created ongoing safety concerns due to loss of vehicle reliability and malfunction of safety-related electrical systems, raising concern about unexpected mechanical or electrical failure during operation. The issues were confirmed and documented by Ford-authorized dealerships and independent service centers. Despite repeated repairs, the same or related problems continued to occur. The vehicle was inspected and repaired by Ford dealerships; however, one servicing dealership (Ford of Ventura) later closed, leaving unresolved issues without continuity of service. Warning lights and system alerts occurred prior to failures along with ongoing electrical malfunctions. Exact dates of first warning indicators are UNKNOWN, but symptoms recurred over time despite repairs. The vehicle was purchased with approximately 38,500 miles. Due to COVID-19-related delays, dealership availability and parts shortages caused months-long wait times for service, and when the vehicle was finally inspected by a dealership, it had approximately 60,000 miles. Major system failures occurred well under 100,000 miles. Ford later declined assistance, citing out-of-state purchase and maintenance not performed exclusively at Ford dealerships, despite regular routine maintenance. The cause of the failures is UNKNOWN, but the pattern suggests systemic mechanical and electrical defects rather than owner misuse. All invoiced available as system will not upload them at this time.

Ford F150 2.7L Ecoboost was running fine. Went to dealer for PCM recall and 3 days later check engine light came on. Went back to the dealer and they say I have a PO430 code now and that I need a catalytic converter at the tune of $3000. Of course I am 8000 miles over the factory warranty of 80000 miles and the extended warranty I bought does not cover it. Seems not right. Is the any help with this issue? Shouldn't Ford be responsible?

When cold starting the engine, a rattling sound occurs caused by the cam phasers not aligning properly. My research shows that Ford claims this is not an issue, and has never issued a recall for this, however, I am worried that continued use might damage the engine further.
