2005 Ford F-150 Problems

What owners report

Owners of the 2005 F-150 most often report window regulators giving way and letting the glass drop into the door, followed by engine complaints centered on the 5.4L 3-valve V8 — spark plugs ejecting from the cylinder head, timing chain and cam phaser noise, and stalling or failsafe mode. Brake complaints describe a pedal that goes to the floor, and a large share of structure and suspension reports describe frame and subframe rust, often found by a mechanic rather than the owner.

1. 1
   Visibility (wipers, defrost, mirrors)

   Power window falls into the door (regulator failure)

   • 273 complaints (25%)
   • median 50,250 mi at 5.0 yrs old (262 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $400 (median of 39 quotes)
   • filed 2007–2019

   Owners describe hearing a loud pop or bang, then the window glass dropping inside the door and staying there, often while driving or in rain. Several say it happened to more than one window on the same truck, and the fix was a regulator or regulator cable replacement at the dealer. Complaints commonly note the window cannot be raised afterwards, and some mention prior warranty repair of a different window. Mostly reported between roughly 30,000 and 56,000 miles, on trucks a few years old at the time.

   What to check: Raise and lower every window, including the rear doors, and listen for cable slack or a slow, uneven track. Ask whether any regulators have already been replaced.

   2 excerpts from owner complaints in NHTSA records

   “This is the second time my window regulator failed in my truck. I was on the freeway and the regulator popped and the window fell. This, alone, scared me enough to make a jolt in my truck and secondly created quite a problem while driving on the freeway. If the weather conditions were not as good as they were, it would have been a serious problem.”

   NHTSA complaint #10322749, filed 2010-03, 50,000 miles

   “My 2005 Ford F-150 front passenger window fell inside the door. This is the second time I have had this same problem, first time it was my front driver side window, the dealer repaired it, it was the regulator. This time I disassembled the door panel so I could 'attempt' to fix the problem myself. Upon looking inside the door at the regulator/motor, all I saw was the cable wrapped around the regulator.”

   Body and structure

   Frame and subframe rust

   • 69 complaints (6%)
   • median 75,823 mi at 12.8 yrs old (48 state mileage)
   • filed 2005–2025

   Owners report rust-through on the frame and subframe, concentrated toward the rear and under the cab, in some cases with cracking near the rear leaf spring mount or the bed sitting visibly low. Complaints describe mechanics or body shops refusing to put the truck on a lift or advising it not to be driven, and owners say the manufacturer offered no assistance. Found mostly on trucks with 75,000 to 200,000+ miles, often in states where road salt is used.

   What to check: Look under the truck at the frame rails above and behind the rear axle and at the spring mounts for flaking, holes or cracks, and be wary of a fresh undercoating.

   “Frame rusting terribly and frame cracking near drivers side forward leaf spring mount. Truck has only 128,000 miles. Do not haul or tow any where near the trucks capacity. Normal driving and minor off road use.”

   NHTSA complaint #11413821, filed 2021-04, 127,000 miles

   “The contact owns a 2005 Ford F-150. The contact stated that when he had the vehicle serviced that the independent mechanic informed him that the front and rear frame of the vehicle was rusted and he should not be driving the vehicle. The manufacturer was made aware of the failure but provided no assistance but did inform the contact to contact NHTSA. The failure mileage was approximately 170,000.”

   Engine

   Engine tick, rattle or knock from timing chain and cam

   • 166 complaints (15%)
   • median 74,418 mi at 6.6 yrs old (150 state mileage)
   • 20 mention a crash, fire or injury
   • owner-quoted repair $3,000 (median of 23 quotes)
   • filed 2005–2025

   Owners describe a ticking or rattling from the engine that is loudest at idle when warm, and in some cases progressing to a heavy knock, shaking and stalling. Complaints mention cam phaser or timing chain and tensioner diagnosis by mechanics, and repairs including coils, plugs and throttle body that did not resolve the noise. Several report the engine ultimately needed major work or replacement. Widely spread in mileage, from about 30,000 up past 200,000 miles, with many reports above 100,000.

   2 related service bulletins

   What to check: Listen to the engine at idle when fully warm, not just cold, and look for a recent history of coil, plug or cam sensor work that did not silence the noise.

   2 excerpts from owner complaints in NHTSA records

   “Bought the truck used at 150000 miles. After 5000 miles the loud ticking that these trucks are known for became louder. At 161000 miles the engine died. I started it up in my driveway one morning and instead of just ticking, it was knocking 100x louder. The truck began shaking violently. Then it just died. All this happened in a matter of minutes. Had it towed to a shop, and they said I need a whole new engine. I can't help but think if I was driving and this happened, what the outcome would be. …”

   NHTSA complaint #10927783, filed 2016-11, 160,478 miles

   “While driving 75 MPH on interstate 40, vehicle went into fail safe mode (happened a couple of times). Subsequently, engine began with a ticking noise with ever increasing rattling/shaking to a point that the engine had to be turned off. This happened numerous times while stopping or idling in city traffic. Local Ford dealership replaced all coils & plugs, throttle body, fuel filter, etc. Vehicle ran fine for six months, however the rattling, knocking, shaking, surging, stalling have returned two fold. …”

   Engine

   Spark plugs ejecting from cylinder head

   • 62 complaints (6%)
   • median 90,500 mi at 6.5 yrs old (56 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $915 (median of 18 quotes)
   • filed 2007–2025

   Complaints describe a spark plug blowing out of the cylinder head while driving or during service, sometimes stripping or damaging the threads on the head, and in some cases a coil pack coming loose with it. Owners report the truck running rough or misfiring beforehand, and repairs ranged from a thread insert to head or engine replacement. Some describe being charged for broken plugs during a routine 100,000-mile plug change. Reported from roughly 20,000 to 150,000+ miles; several cases appear around or after the scheduled plug service.

   2 related service bulletins

   What to check: Ask whether the spark plugs have been replaced and whether any plug had to be extracted or a thread repair performed; listen for a ticking or popping sound from the engine bay.

   2 excerpts from owner complaints in NHTSA records

   “The coil packs and plugs have been changed on different times and the vehicle still has the same problems. Ford has to find a better solution to fix these ongoing issues so the customer does not have to keep paying all this money for the same problems over and over again. Engine lost power on several occasions and shakes when idling. Paint on front of vehicle started peeling off. …”

   NHTSA complaint #10494593, filed 2013-01, 20,000 miles

   “Spark plugs and coil pack continue to eject themselves from the cylinder head.(f150 blown out spark plug). This continues to be a problem and has occurred while the car is in motion on the hwy., traveling at a speed of about 30 MPH.”

   Brake pedal goes to the floor / weak power assist

   • 181 complaints (16%)
   • median 38,000 mi at 3.5 yrs old (166 state mileage)
   • 28 mention a crash, fire or injury
   • owner-quoted repair $585 (median of 9 quotes)
   • filed 2005–2025

   Complaints describe the brake pedal travelling to the floor when stopping, sometimes with the brake warning light on, requiring a second pump to get braking back. Some owners were told the brake booster vacuum supply hose had come loose or was falling off and it was glued or clipped back in place; others were told the ABS module needed replacement and that the part was no longer available. Other reports list repeated caliper and rotor work. Reported from very low mileage up to about 175,000 miles, with several cases below 60,000.

   “Brakes failed 3 times. Last time pedal went to floor and I went through stop sign. Also had throttle sticking. After pedal sinks to floor & you try a second attempt then it works fine. Truck has been at dealership since february 10, 2006 & is still there today april 17, 2006. Ford refuses to acknowledge or repair problem. Ford told me to drive it until it happens again and notify them. Vehicle is not drivable in it's current condition.”

   NHTSA complaint #10155487, filed 2006-04, 9,400 miles

   “The contact owns a 2005 Ford F-150. The contact stated while driving approximately 30 mph and depressing the brake pedal, the brake pedal traveled to the floor. The driver immediately turned the steering to avoid hitting several kids that were crossing the street. During the failure, the brake warning light illuminated. The cause of the failure was not yet determined. The local dealer was notified of the failure. …”

Buying note. Check the frame for rust-through and the window regulators before anything else, and on 5.4L trucks ask for service records covering spark plugs, timing chain and cam phasers, since those repairs are the expensive ones owners describe.
