problem #11

Jan 152015

F-150 XLT 4.6L V8

  • Automatic transmission
  • 152,969 miles


The plug that blew out was a stock plug. I have only owned this truck a little over a year so I haven't ever changed them. So I know it was not a tightening problem on my end. Completely ridiculous something like that can happen.

F-150 STX 4x4 4.6L V8

  • Automatic transmission
  • 60,495 miles

I just got done putting new brakes on front axle and cleaned up back brakes. Took truck for test drive and spark plug blew out. Can't believe that it cost $585 to replace one plug and coil. This is the worst thing I have ever experienced. I just retired from Ford and am very upset that they don't think is should eligible for a recall. They are screwing the consumers with this issue. I asked my mechanic if I should replace all the plugs and he told me it will not stop this from happening again. I'm gonna trade by truck in but an seriously thinking of buying another brand.

F-150 5.4L

  • Automatic transmission
  • 53,000 miles

My truck is a 05 ford f-150 4+4 with 53,000 miles. The spark plug broke off and went down in the motor causing the motor to lock up. It cost me 6,400 dollars to fix it. Ford would not do anything to help me. It had the same plugs in it that came with the truck.I am 52 years old and this has hurt me very bad. I will never buy another ford of any kind. nor will any of my family or friends and I will tell everyone I see about this. I hope ford gives their CEO's a big raise this year. My family will not have a christmas Thanks To FORD.

F-150 4.6L V8

  • Automatic transmission
  • 78,968 miles


I had just purchased this used truck and had put only 1700 miles on it, when the #3 spark plug blew out causing two gas explosions when I was 800 miles from home. It cost $981.98 towing and repair to a Ford garage. I had them install a spark plug insert instead of replacing the cylinder head at a cost of $3,900.00. Before the spark plug blew out I did smell gasoline around the engine a few times and I checked but found nothing.

I found that Ford does not cover this known problem out of warranty.

Ford recommendation is to replace the cylinder head. Ford has a service bulletin

TSB 07-21-2 to install a spark plug insert.

The spark plug blow out is a design defect by Ford of the aluminum cylinder head and should be covered by extended warranty especially since there is a potential of fire and explosion hazard. The owners manual states the spark plugs should be replaced at 100,000 miles. My spark plugs were OEM at only 79,000.

never replaced spark plugs because ran great and fuel mileage was real good.Spark plugs should not come loose ,no matter how many miles .when they are installed at the factory.Ford should be responsible.

problem #2

Jul 032008


  • 60,000 miles

Over a period of 20,000 miles I had to replace the right head not once but twice- Since 50,000 mile mark I have shelled out in excess of $12,000 in repairs and I have the receipts from the local Ford dealer. Tongue in cheek, I sent a letter off to CR at Ford along with copies of the receipts requesting why I should ever again think of buying a new Ford. Last week I bought 2 new Toyotas.
