2015 Ford F-150 Fuel System Problems

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.

Fuel inlet light on

The throttle body will randomly get stuck either shut or open and when this happens the truck goes into a “limp” mode that makes the truck lose all power. There is no warning of when it will happen or to get your vehicle checked. If this were to happen pulling into traffic it could cause a serious wreck since you cannot get the truck to accelerate in any way. This problem has been reproduced numerous times.

at 63000 miles in June 2021, randomly while driving, it presented warning "Hill Start Assist unavailable" and other traction control warnings,, throttle goes to idle in traffic, vehicle coasts and dies. Key off & on restarts it. Code P2112. Ford dealer replaced throttle body motor under extended warranty on June 3, 2021. MotorCraft Part has 2 year warranty. On June 17, 2023 (14 days out of part warranty), at 93,000 miles truck does identical behavior. Starts & runs fine, presents warning with random frequency (4 times this morning) at various speeds from 30 mph up to 75 mph in freeway traffic. Throttle goes to idle, truck coasts at 3-5 mph until ignition key recycled. happened this morning at 65 mph on freeway in construction zone with no safety shoulders. VERY dangerous!!!

While driving with my family the truck gave several error messages and a check engine light. I pulled over immediately because the truck lost power and the stability control started shaking violently. I was able to safely maneuver out of traffic, but I cannot imagine what would have happened if I was on a busy highway instead of a small side street. Apparently this is an issue that has been fairly common with Ford from what I have seen online. The vehicle is at the mechanic now for repairs. He has determined that the Throttle body needs to be replaced.

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.

Throttle Actuator control system error (Hill Start Assist Not Available/Service AdvanceTrac). Vehicle lost accelerator power at highway speed in traffic. Traveling at highway speed without the ability to accelerate resulted is difficulty exiting to the shoulder when vehicle lost acceleration. Computer code error P2112 was later diagnosed with subsequent check engine light. This is a known problem. As such, Ford had issued a temporary Service Bulletin 16B32B for this issue on various models. However this narrow window for repair is not adequate for the issue at hand.

Warped exaust manifolds due to broken bolts. Both sides. Result in bad emmisons and possibly of carbon monoxide entering occupied cabin and poisoning passengers. Glazing/ warped rotors. Unknown cause.

While driving at 70 mph in heavy traffic the vehicle experienced a complete loss of power narrowly avoiding an accident. Suspect failed throttle body was the cause for loss of power.

The fuel economy for my truck is not working at the best I’ve have gone from medium gas mileage to poor (at its best) 18-20 mpg - 10 or less

Warped exhaust manifold. The design of the exhaust manifold where it connects to the turbo is not engineered correctly and only has 2 mounting studs. The heat generated from both the exhaust and the turbo is more than the 2 manifold studs can handle and the exhaust manifold warps causing a broken manifold stud and exhaust leak. This is clearly an engineering design fault and this part should be recalled. Loss of performance, and fuel economy. No warning signals in the vehicle. This is the second time that the exhaust manifolds have warped. The first time was covered under the powertrain warranty and replaced by the dealer at +/-60,000 miles. This problem has now occurred again and is no longer covered under warranty at 86,000 miles

Went into 'limp mode'. Advance track, hill descent warnings. Wouldn't throttle. stopped going downhill. Known Throttle Block problem.

Manifold leak.

THE FOLLOWING HAS HAPPENED MULTIPLE TIMES. I AM DRIVING IN TOP GEAR (5TH OR 6TH) AT APPROXIMATELY 55 MPH. I ATTEMPT TO PASS SOMEONE AND SUDDENLY LOSE ACCELERATION AS I PRESS THE ACCELERATOR PEDAL. THE TRANSMISSION SEEMS TO GO LIMP. AFTER A FEW SECONDS MY ACCELERATION RETURNS.

THE CAPLESS FUEL CAP FLAP IS ALLOWING AIR INTO THE TSNK CSUSING THE CHECK ENGINE LIGHT TO COME ON. I KNOW NUMEROUS FORD VECHICLES HAVING THE SAME PROBLEM. I FEEL FORD SHOULD RECALL THESE PROBLEMS .

I HAVE A2015 F 150 WITH 47,500 MILES. I WAS DRIVING ON THE HIGHWAY WHEN THE ENGINE JUST STOPPED. I WAS ABLE TO GET TO THE SHOULDER WITHOUT GETTING HIT. WHEN I TRIED TO START THE TRUCK IT WOULD CRANK BUT WOULDN'T START. I ENDED UP CALLING MY MECHANIC HE TRIED TO JUMP IT DIDN'T START. HE TOWED THE TRUCK TO THE SHOP, HE ENDED UP CHANGING THE FUEL PUMP AND FUEL PUMP MODULE. I LOOKED UP THE PROBLEM ON THE INTERNET AND FOUND MANY OTHER FORD TRUCK OWNERS HAD THE SAME PROBLEM. I CONTACTED FORD THEY SAID THERE IS NOTHING THEY CAN DO. MY MECHANIC SAID THE PUMP SHOULD NOT GO BAD WITH THE MILEAGE MY TRUCK HAD. WHAT HAPPENED COULD HAVE LEAD TO AN ACCIDENT.

THE VEHICLE WENT INTO "LIMP MODE"

P0316,P0300 AND U0140-00 CODES POPPED UP.

VEHICLE STALLED WHILE DRIVING AT LOW SPEED. DEALER FOUND FUEL PUMP SENDING UNIT AND MODULE HAD FAILED AND NEEDED TO BE REPLACED.

WHILE TRAVELING ON THE HIGHWAY AT 70MPH, MY VEHICLE WENT LIMP, ABRUPTLY SHOOK AS I PULLED OVER TO THE SHOULDER TO AVOID A COLLISION. MY INDICATOR LIGHTS LIT UP LIKE A CHRISTMAS TREE..."HILL ASSIST", "SERVICE ADVANCETRAK" " THE "WRENCH" ADN MY CHECK ENGINE LIGHT REMAINED ON. TERRIFIED, I GOT STOPPED, TOOK THE KEYS OUT AND HAD IT TOWED TO THE NEAREST DEALER. THEIR DIAGNOSIS WAS THAT IT WAS A THROTTLE BODY FAILURE. MY SERVICE MANAGER REQUESTED THAT I CALL FORD CUSTOMER CARE. I DID THAT IMMEDIATELY FOLLOWING THE DIAGNOSIS WITH MY REPAIR BEING ABOVE $650. AFTER A WEEK OF RESEARCH, FORD CAME BACK AND STATED THAT THEY WOULD NOT HELP ME OUT AT ALL. THERE ARE RECALLS FOR THE SPECIFIC PROBLEM INCLUDING AN EXTENDED WARRANTY FOR 10 YEARS AND 150,000 MILES, HOWEVER I WAS TOLD THAT I COULD NOT RECEIVE ANY HELP FOR THE SAME PART. I EXPERIENCED A PREKNOW CONDITION WITH A PART ON MY TRUCK THAT WAS FAULTY WITH MYSELF TO BLAME. IF I HAD KNOWN ANY OF THIS I WOULD HAVE NEVER PURCHASED THE VEHICLE.
