Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Vehicle jerked when driving down highway when you reach 45 to 50 mph. I would let off gas and then give it gas again and it would not jerk. Check engine light appeared so I took it to Ford dealership and they run a check. Told me I need another motor. This truck has 154000miles. It has not overheated.

On November 16,2011 I was on my way to see my mother who passed away and while driving it sounded like a bomb went off and I had vehicle towed and it was spark plug issue, then two years later it happened again, I changed on plugs and coil packs at garage, now two years later another 3rd plug breaks into engine, now in need of new engine. Miles are over class action suit but not by many. My truck is worthless for Ford lack of fixing this issue. I do have documents to show. This problem is a repeated issue and end result for them not to recall issue sooner has ended with a none working truck engine.

On 3 occasions my vehicle, over 4 months, has had a complete engine failure. This occurred most recently while I was exiting the interstate.when the engine shuts down so does the dash and brake lights, it also stops power steering and brakes. This time by reacting quickly I was able to put the vehicle in neutral and restart, after turning key to off position first.

Spark plugs on the 5.3 liter engine when replaced break--in return the book said pull engine and pull heads to replace spark plugs. The law suit filled Ford admits to bad decision on spark plugs and will reimburse some of the cost. The cost is very high--the book and Ford's shop said the engine needs to be pulled to pull the heads to replace the spark plugs. There was never any software updates, and now the vehicle requires them. The error in the cluster software recall was suppose to be repaired and I read from the experts all software should have been upgraded with the cluster error. There are 42 P.M. Ford and nhsta knew or knows about on my vehicle and nothing has been done, I am a 100% dav and my vehicle has been broken down. The 2006 harley davidson F-150 that cost so much with it's on board computer system does not work. I have read many complaints about the F-150 engine cutting out, I pulled out to pass on a two lane road and almost got killed when mine cut out so bad. A two cylinder would have done better than that V-8.

Originally factory installed sparkplug blows out of the engine head traveling at approximately 35 mph. This was disclosed after taking vehicle to a Ford dealership for diagnostics as there was a loud noise while engine running and loss of power. Repair cost was $617. Discussion with dealer discloses that this a well know problem by Ford management, a tbs has been issued. Further Ford has denied any responsibility and will not provide any monetary assistance. This is a Ford created design engineering defect that Ford just ignores and let's the customer pay for its mistake. Customer is subject to cost of repair that is far from normal wear and tear, a safety concern of fire in engine compartment from raw fuel blown out of the hole vacated by sparkplug, a reliability issue and a safety concern from sudden loss of power. This problem should be covered by a federal mandated recall since Ford is making this a consumer problem ignoring the fact that it is a engineering, design or manufacturing problem for which it refuses to accept responsibility. In addition the trade in value of this vehicle will be reduced by the Ford dealership that is aware of the problem evan for the customer that did not encounter a sparkplug blowout and at private sale if prospective buyer checks on vehicle via any internet automotive site. Again Ford lets consumer absorb cost of defect it created.

Morning of July 23,2015, I was driving about 25 mpr speed when number three spark plug blow out of the cylanderhead on my F-150 Triton V8. Took it to the local machanic shop walton's. three hours later, walton's had to replace and resleeve number three cylanderhead and replaced electrical sparkplug wire, plus replaced all eight spark plugs. All at a cost of $543. Not only this happened to me but walton's stated that I was the 10th person this week this has happened too. I presented the part to my local Ford dealership where we bought the truck (hall's Ford Motor Company) brand new in 2006 and paid cash to the sum of $30,000. I asked them if they know of this problem with Triton V8's. they stated they did but no know recalls and they too had several repairs come in for the same thing in the pass week. They also stated that the Ford Motor Company was aware of this matter but never let there customers know about this problem yet because there was no recall on file to let them know. This thing where the spark plugs come flying out of an engine can be very hazards, it could cause a crash or even give a person a heart attack because the truck sounds like world war III going off under the hood and it may even start a fire. This matter needs to be taken care of by Ford.

The contact owns a 2006 Ford F-150. The contact stated that the vehicle was taken to an independent mechanic for routine maintenance. While at the independent mechanic, the contact was notified that seven of the eight spark plugs in the vehicle were fractured and needed to be replaced. The contact stated that one of the fractured spark plugs remained in the cylinder head. The mechanic stated that the cylinder head had to be removed from the engine to remove the fractured spark plug. The vehicle was not repaired. The manufacturer was notified of the failure; however, the contact was not offered a remedy for the failure. The failure mileage was 84,000.

2006 F-150 lost all power function while traveling down the interstate. I lost power steering and brakes. The cause is a corrosive fuel pump control module. After taking with my local Ford dealer I was made aware that this is major safety issue and one that fmc refuses to recognize. This incident could have resulted in a major accident. I was lucky enough to be able to signal to the cars around me that I was having trouble - however I was still almost rear ended twice before being able to pull off to the side of the road.

The engine began to tick on top. Later it began to tick on the bottom. The engine light came on and I had it checked. The code said it was a cam sensor. As it turned out the engine was not getting the proper amount of oil due to a clogged a oil port restriction. End result had to replace the engine. While at the service center another truck came in with the same problem with similar mileage. Now my son who has a 2005 Ford F150 is experiencing the same issues with his truck with 96000 miles that's three that I know of.

Engine had blown a plug out about 300 miles ago on the number 3 was repaired with repair kit new plug and coil was put on. Was traveling started up hill engine began to miss drove 20 miles to destination had truck tested at advance auto parts readout stated misfire on cylinder 1 and 3 and bad coil on 3. replaced coil 3 again took to mechanic his computer read out was number 8 coil was bad replaced it engine continued to miss took it to the mechanic he changed all the plugs the 2nd plug on drivers side was loose and ready to blow out and he took the number 3 plug out that had been replaced prior the whole bottom of plug was melted could have resulted in a fire looked down in engine with camera the piston was destroyed. This problem is from the factory installed plug blowing out and fragments going into engine. Now I have to replace my engine 2500 out of my pocket D/T poor head design Ford is well aware of this problem and refuses any assistance Ford actually has excluded blown plug repair from their warranty. When you purchase a new vehicle you expect to get more than 106000 miles.

Vehicle started missing and bucking. Brought into mechanic and was told this is a very common problem with Triton 5.4L engine. Needs spark plug change and chances are they will break off in engine while changing (which 5 out of 8 did). Total cost a shameful $800 (estimate was between $600-$1200). Mechanic pulled out many prior invoices from owners with the exact same issue. The spark plugs in these engines should be recalled.

Engine started making a loud noise upon inspection of engine found that the back spark plug on passenger side had blown out from head and of course stripped the treads from the head the spark plugs are the ones that came from factory they have never been removed or replaced vehicle was purchased new after reviewing information on the internet this seems to be a major problem with Ford 4.6 and 5.4 engine as well as resulting in fires and considering Ford makes a repair kit. If this has effected this many vehicle shouldn't Ford foot the bill.
