What owners say about the fuel/propulsion system

Verbatim from NHTSA complaints, newest first
“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.”

“My vehicle (2018 Ford F150) is presenting with the same issues the 2021- 2023 ford an Lincoln models regarding the fuel system with my truck sputtering in 7th and 8th gears and stalling. It has stalled a few times in the past few months. The spark plugs have been changed, purple fuel styrene cleaner has been used regularly, filters changed, basically all trouble shooting has been done with no significant change. Maybe there are others who are experiencing the same out there. My vehicle is well maintained, in fact I just put upwards to $8k into it this year.”

“While driving to Sam’s Club (approximately 20 miles from home), my 2018 Ford F-150 3.5L EcoBoost began running very rough, and the check engine light came on. I had the vehicle scanned, and diagnostics confirmed that the cam phasers are failing — the exact issue I had replaced under warranty at approximately 59,000 miles. The vehicle now has just 88,000 miles, and this failure occurred in under 30,000 miles since the original repair. I have maintained this truck with extreme care. I only use Motorcraft parts and fluids, change the oil every 3,000 miles or sooner, and always use premium fuel. This is not a maintenance issue. This is a design or part failure that Ford has not properly resolved. When the phasers were replaced the first time, I was told there was no warranty on the replacement parts. That is unacceptable. A known failure being replaced with an equally defective part is not a resolution. Ford is aware of this issue — there are multiple TSBs (including TSB 21-2130 and 19-2208) and widespread complaints across owner forums — but they have taken no responsibility. I paid over $44,000 for this truck and should not be facing the same critical engine…”

“In November of 2024, my truck was shaking, accelerating erratically, and felt like the transmission was slipping. The check engine light came on as well. I took it to the shop and after diagnosing that it was a misfire issue in cylinder 6, they replaced spark plugs, fuel injectors, and tried to switch out new coils. They found gasoline inside cylinder 6, and upon doing a compression test, it was well below 100%. The truck continued to have misfires in cylinder 6, ultimately leading to 0% compression in that cylinder after taking it back to the same authorship to diagnose. After researching online forums and technical bulletins, it’s clear this issue is not uncommon among 2.7L EcoBoost engines from this model year, suggesting a manufacturer defect. The cost to replace the engine (as now recommended) has been estimated at nearly $10,000. With the history of regular oil and maintenance by the previous owner and myself, I feel this is a manufacturing defect that could potentially cause harm to the driver and passengers.”

“I just had to replace my fuel pump due to sudden failure. It was repaired this month at Crossroads Ford of Wake Forest NC. I as well the dealer have the receipts for the repair cost. I believe it should be included in the current recall just issued by Ford and be reimbursed.”
