2015 Ford F-150 fuel/propulsion system problems

“While parked and shut off at a gas station in Lakeside, CA, my 2015 Ford F‑150 XLT spontaneously caught fire under the hood. The fire appeared to originate in the fuse box area, specifically where the fuel pump relay is integrated. The incident posed significant risk, occurring near a fuel pump while my child was in the vehicle. A gas station employee assisted with extinguishing the fire. The cause is believed to be an electrical short. There were no modifications or recent repairs.”

“It's the same issue as Recall Notice 22S02/NHTSA Recall 22v011. The replacement part is MR3Z-7583-A 1X ($2-$5 part with 30 second install), but they do not show it under parts for my truck, they would prefer to sell me the whole brake pedal assembly ($50+ part and labor probably diagnosis charge in addition to part replacement). The part becomes brittle and breaks. This caused dead battery, 5 hours from home, due to lights staying on, allowed me to start and put truck into gear without touching the brake, lost acceleration between 45 & 50 mph, cruise control would not turn on and message presents that hill assist is not available.”

“What component or system failed or malfunctioned, and is it available for inspection upon request? Transmission lead frame - error P072 - traveling on the interstate at 65mph and transmission downshifted in 1st gear nearly causing the car behind me to rear-end me. Lucky i wasnt killed or serioiusly hurt. How was your safety or the safety of others put at risk? yes Has the problem been reproduced or confirmed by a dealer or independent service center? yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no”

“STARTED TRUCK AND DROVE ABOUT 1/4 MILE WHEN IT LOST ALL POWER AND NUMEROUS MESSAGES STARTED FLASHING ON THE SCREEN. TRUCK HAD NO POWER AND I HAD TO PULL TO THE SIDE OF THE BLVD TO LET OTHER TRAFFIC PASS. SHUT ENGINE OFF AND RESTARTED. STARTED OKSY BUT RETURNED HOME. LEARNED FROM MY MECHANIC 180 MILES AWAY THAT IT IS THE THROTTLE BODY, A COMMON PROBLEM TO WHICH THERE IS NO RECALL BUT POSSIBLY AND EXTENDED WARRANTY. TRUCK HAS 49,253 MILES ON IT.”

“Throttle body failure approx every 45,000 miles. Bought F-150 new, now driven it approx 135,000 miles. Failure occurs when driving a various speeds, incl 75 mph. Engine shuts down, complete loss of power. DANGEROUS situation; safety at risk! Unexpected & random loss of power - w/ passengers aboard - in various traffic situations. After engine shuts down, restarts, then randomly shuts down until a new throttle body is installed. First throttle body failure repaired (=throttle body replaced) @ Ford Dealership in Price, UT. 2nd failure repaired @ Ford dealership in Hamilton, MT. Both covered by extended warranty. 3rd failure repaired [XXX] @ Hamilton, MT @ $324.55 personal expense. Check engine light warning occurs.”

“Chech engine light keeps coming on. Dealer said it was an evap canister issue, I told them warning had come on prior for check fuel fill cap. (Capless). Said they needed to replace purge cylinoid. So as I'm paying $500 for the repair, I'm told this might not fix the issue. What? Started with small evap leak. And fuel door codes. That only came on at 1/4 tank used. Now it's a large leak that comes on every time I start the engine. And I got the check fuel fill door warning again. I've done every trick listed on forums to clean and lubricate the fuel fill door, it did help for a while but as stated above problem is now much worse. Dealer should know how to fix this issue once and for all. Forums note that this is a common problem with no quick solution.”
