Manufacturing defect - plug thread failure vehicle is a 1999 ford f-150 4x with 5.4l triton and approx. 45,000 miles. While unaggressively accellerating at normal highway speeds the engine lost power and a loud popping sound could be heard. The vehicle was immediately pulled to the side of the highway, turned off, and towed to a repair facility. No injury or crash occurred. Investigation indicated a spark plug and coil had been ejected from the head. The plug was the 2nd from the front on passenger side. The threads in the head were stripped such that a new spark plug could not be seated. A helicoil was installed for approx. $300 and loss of vehicle for a week, but it failed after approximately 3 months. This failure was evidenced by engine misfire, power loss and sluggishness. Investigation revealed that same plug was not firing, and was not able to be removed because the helicoil threads were also stripped. The head was replaced at a cost of $3,626 with and additional 2 weeks lost vehicle use (2 comparable quotes from reputable auto repair providers were obtained). Repair time was longer than usual as the part had to be ordered from out-of-state and expedited shipping was deemed too expensive. At this time, however, the engine misfires continuously at idle and frequently at highway speeds. The vehicle is currently in the shop for a 3rd time to investigate this continuing condition.

1. No events LED to failure. 2. A spark plug blew out of the engine. The consequence is that the engine runs poorly, is loud and has little power. 3. No repair has been made yet.
I was towing my trailer and had just left my house and got a mile down the road when I heard a loud pop like a tire blowing and I quickly tried to find a place to pull over. I later found out I had a blown plug and of course it wiped the threads and shot up and destroyed my coil on top so I had a helixcoil put in and a new coil . My truck is a 99 5.4 with 67,305 miles on it with the original factory plugs .
Spark plug blow out on 2nd to last cylinder on passenger side of 1999 f150 w\ 5.4 liter triton engine.
Dt: bought a used truck, and after the warranty expired had to replace the starter/the ball joints/he upper tie rods, and the control arm on both sides. Engine manifold split, and exhaust system rusted. Later, while driving tie rods came off. There was a slight drop at the entrance to the parking lot, and as vehicle went back up the drop, it slid and there was an impact. Got out of the car, and saw that the tie rod came off and gouged into the pavement. Spoke to the manager of country club chevrolet, and he simply gave consumer a discount on parts and labor. Yesterday he went to a certified used vehicle dealer and asked for the 88-point inspection,, and they were unable to provide that information.
I am shocked to discover the thousands of postings on the internet concerning the '99 ford f-150 that blows a spark plug because of too few threads on the engine in the original design. As a victim of this failure, the dealership acknowledges that this happens all the time and that there is no remedy for it. The cost for repair is almost $3000 and there is no guarantee that it will not recur. Seems that ford should be forced to recall these engines as it can lead to fire (as straight gas goes into the engine compartment) and the spark plug could spark as it blows igniting fumes or fuel. I will never feel fully safe in this vehicle again and am quite disappointed that ford is getting away with such a faulty design! Please help all ford f-150 owners that will fall victim to this costly repair and dangerous situation.
I have a 1999 f-150 ford pick-up truck 4-2l v-6, I was having a low cooleant problem. Took it to mcdonough radiator shop, they replaced water pump and gasket. It was still loosing cooleant. I called the dealership and ask if there was a recall for this vehicle and was told no there was not. I took it back to the same radiator shop after a closer inspection they removed the intake manifold and found water in the back two cylinders.they replaced the intake manifold gaskets, I picked the vehicle up I had not drove more than 3 miles before it started to make a knocking noise. I called the repair shop and took it back immeadiately, now they tell me that I have 2 bent push rods. They are suppose to replace them today. I found out later that I was not the only one having this problem, after some research on the internet I found a web site that has an long list of people with the same complaint. When I called ford motor company customer "no service" I was told that there had been no recalls on this vehicle for that problem and that they could not help me in any way because of the warrenty had expired. According to jasper engine rebuilders the problem stems from a poorly designed gasket for the intake manifold and that is what caused this problem, got this information from one of their tech bullitens.
The 4 wheel drive in the consumer 1999 ford f150 engaged in low range while driving. This caused the truck to jerk, lose control and the rear end to go out.*mr the consumer had a new rear end put in but the truck has continued to go in and out of 4 wheel drive automatically. Now the truck start on it's own. The consumer had to disconnect the battery to keep from burning out the starter. When the cruise control is on the transmission wouldn't shift and the RPM's raced into the red. The consumer could hear clicks under the dash while this was happening which resulted in the battery being drained. The radiator leaked.
Oil leak from right rear cylinder (passeger side). Oil is leaking from the cylinder head gasket. Vehicle is a 1999 ford f-150 5.4l windsor, ont, canada engine. 81,000 miles.
While driving approximately 5 MPH, the spark plug blew out of engine. *jb
Driver noticed a brownish liquid leaking from underneath the vehicle while parked. Driver took vehicle to the dealer, and mechanic determined that the head gasket blew out, and needed to be replaced.
Sitting at stop light in 1999 f-150 w/5.4 litre engine,slowly proceeded through light and heard a loud bang followed by very loud and rough running engine. This left me stranded at side of road at 3:00am. Turns out that spark plug ripped away from cylinder head causing expensive repairs. This not only is an obvious mfgr. Defect,but a safety concern as well. The manufacturer knows this is a problem and should step up and do the right thing. Thank you. Doug beeman.
Transmission gears breaking, timing chain loosening.
I have a 1999 f150 truck and a 1999 expedition, both have a 5.4l engine and both have oil leaks on the cylinder head gaskets, they both have about 60,000 miles.
Consumer was traveling at 35 MPH and heard noise from the engine. Vehicle stopped, and had to be towed. After the dealer inspected the vehicle engine was found to be defective.
While the vehicle was idling, a fire started in the engine. The fire was put out and the vehicle was towed. Please provide more information.
I was driving my ford f-150 (after a previous fix of the same problem I was about to experience), when my #3 spark plug blew out of the head unit. 2nd time happened, cost $2500 to fix. Now I want reimbursement for all repair work due to flawed engine design.
*aki was driving my 1999 ford f-150 with 5.4 liter v-8 engine when I experienced a blown #3 spark plug driving under normal conditions on my way to a soccer game. Extended warranty company would not cover problem. Got it fixed with a helicoil for $400 and same #3 plug blew 4 months later. Got it fixed with a new head unit for $2500. Now I want ford to reimburse me for flawed engine design.
Slight tapping that of like a tapping valve for about a week prior to first incident. The second incident occurred with no warning that I noticed.*ak vehicle has now ejected two spark plugs. Spark plugs were not the original from the factory. The first one was on the passenger side, 3rd back. When it came out, it destroyed the coil over the plug as well. It was repaired using a heli-coil solid steel insert which worked ok, but has come back out when the sparkplug was removed. Local ford dealer quoted $1450.00 for a single new head, not installed. The second time, it was the third back on the driver's side. This one killed the motor. I'm not sure exactly what happened yet, but along with the blown plug, I have water in my oil and the motor will no longer turn over, even with all plugs removed. I'll be buying a new motor now when I have the money. Meanwhile, my wife must sit at home with no vehicle and two young children until repairs are made.
I was merging onto a busy road safely, and a spark plug blew out of my engine head. It caused an immediate loss of power and almost caused an accident because the truck would not move in heavy traffic. It also posed a fire hazard as fuel continued to pour into a cylinder with no spark plug sealing the top of it.
I take good care of my pickup however it has broken down on me. It began with a small shutter. It felt like the pickup was having issues idling/accelerating. Only at low (5-10 MPH) speeds did I feel the weakness/shutter. I had this issue for about 4 months, I just assumed it needed a tune up and was prepared to have one done soon. I was towing a trailer (started off fine) then at a stop sign felt that the engine was now shuttering/misfiring even more. Took the pickup to mechanic the next day and found that valve 4 was stuck open and had essentially melted its self open. This in turn caused the piston to get damaged and now I'm faced with replacing the heads or the entire engine. My pickup has 110,000 however (according to the mechanic) there have been other pickups have the same issue with as little as 80,000 miles. I have not been able to find a recall on what I've experienced.
Replaced exahust manafold, my repairman said many ford owners had same problem.
Drove my f-150 truck to eat then when I came out I drove it about 100 yards and stop and did about 15 minutes shoping at home depot when I came out and started it it made a bang. It sounded like a hole in the tail pipe. When I took it to the dealer they said it was a cylinder head from a blow spark plug.
My f150 p.u. Has a stress crack in the curve of the door by the window. The latch is not tight enough, so the door is hard to shut. My windshield wipers turn on by themselves, the odometer light goes on & off, the seat belts do not recoil & the "door ajar" light gets stuck, eventhough all doors are reshut. Engine sometimes runs rough eventhough has just had 60,000 mile check. The ford dealership wants to charge me for new part to fix odometer light $300+plus labor, $58 for door part+labor. Haven't talked to them about "rough running", I'm sure they'll want more $$ to fix it too.
While driving , suddenly the vehicle started shaking. The repair shop performed a diagnostic and indicated that it could be the spark plugs. The spark plugs were replaced, but didn't correct the problem. The butterfly to the fuel injection on the passenger side of the engine motor froze and stopped the flow of the fuel, which caused damage to the fuel injection thus damaging the timing belt, and piston. The entire engine motor fell apart from the inside out per the mechanic.
While driving, the head gasket would leak oil. The mechanic repaired the problem once, but did not resolve the problem. Please provide more information.
While driving at 65 MPH, suddenly there was a popping noise, then the vehicle stalled. The spark plug had came out the engine cylinder head. This occurred because of a design flaw, there was insufficient tread to hold the spark plugs. The cylinder head was replaced.
While I was driving 30 miles per hour, my back passenger side spark plug shot out of my head, I have a warranty but the dealership is not sure if they will cover this incident. I have noticed all over the internet that this is a common problem, what is wrong with ford, how can they make something defective that is so costly to their customers and not recall the item? The dealership is quoting me $3800.00 to put a new head on the 1999 ford f150 which I thought was a dependable vehicle. I have driven fords all of my life and I doubt I will ever buy another one, not to get this kind of treatment.
My 1999 f-150 5.4 ltr 4wd started making loud ticking noise @ 39,000 miles.took truck to burch ford from whom I purchased vehicle & they diagnosed ticking noise as a bad cat. Cvrtr!!! They also advised me of leaking head gasket from (r)rear head and a repair cost of $3,200 w/ (12 mo./12,ooo mi.warranty !!! )on repair.when I picked up vehicle & started engine,the same loud ticking noise (only worse) was still there!!! Burch ford & ford motor corp refused to even acknowledge problem or warranty their repair.while trying to get assistance, I drove vehicle bare min and aprox. 300 miles after the "repair",the engine blew # 3 spark plug out of (r) head like like a rocket & massive loss of power which nearly left me in direct path of a loaded semi truck !!!(thought I was going be crushed to death).I had truck towed back to burch ford & they faxed me a estimate of $3,200. More to replace head (now total is $ 6,400. From the two repairs!!!) and in bold print @ bottom of est. Say's ....no warranty!!! Vehicle needs new engine & neither the dealership or ford motor corp are willing to ohnor their original repair,or assist in this catastrophic problem that research shows has occuring by the hundreds on 4.6 ,5.4 & now many v-10 engines from 1996 to 2004........ (8 yrs.)!!! My truck is my pride & joy & with aprox. 39,000 miles on it,my $ 40,000.00 ride may be a total loss due to current book value & contraversial $$$$$cost of repair!!! This is my 6th ford vehicle(all of which were paid off in full 1-2yrs.early!!!)in the last 9 yrs.I've been a more than loyal ford customer,...but with blatent dissregard for their bread & butter,(loyal ford customers) ford seems to be for 8 yrs. Now; grossly and w/o any remorse, far less than a loyal automobile manufacturer !!!...respectfully,...j.l.
The consumer took vehicle for service because of a ticking noise heard on vehicle. The dealership indicated that the ticking noise was coming from the catalytic converter, and the head gasket had blown. Which resulted in an oil leak into the exhaust manifold. The dealership replaced the catalytic converter and the head gasket; however, the ticking noise still exist after the repair was performed. Within 300 miles after the parts were replaced, the spark plug came out of the right side of the engine head which resulted in engine failure. The dealership refused to honor repair warranty and perform any further service on the vehicle.
