2002 Ford F150 lightning, three blown spark plugs. Two were repaired under warranty, one out of my pocket. Ford did not acknowledge any problems with the Triton cylinder head and did nothing about it. Ford left me stranded three times, twice on the freeway. Thanks Ford.

On thurs. 12-07, I was driving 40 mph when I heard a loud pop, the truck was running rough and loud. I pulled over, it blew a spark plug(#4). Towed it to the dealership, was told the head would be replaced, then when I returned for the truck was told they would only repair the hole with a helicoil, which I found a service bulletin #0214 that states engine assemblies with aluminum cylinder heads repaired in vehicle have been found to leak coolant and/ or oil from the cylinder head gasket area. The dealership seems to think this is trivial, and refuses to replace the head under warranty. Truck is an '02 F-150 lightning. 5.4 motor.

Since purchase of vehicle three coils have gone bad and had to be replaced. I was told by the mechanic at a Ford dealership to not wash the motor on the vehicle. I was also told that they have had several problems with the coil configuration on all Ford, Lincoln, and Mercury vehicles since they switched to individual coils for each cylinder. This is very expensive to replace and it has to be checked on the computer to tell which one is bad.

Manufacturer uses faulty electronic component in vehicle ignition system. No part of system provides for indication of potential failure or complete failure. Once part fails, the vehicle experiences random misfiring in cyclinder which causes damage to spark plug threads of aluminum cylinder head. Eventually spark plug is blown from cyclinder head resulting in loss of power and function. Resulting damage to aluminum cylinder head requires replacement at cost of @ $3,000. Replacement parts are identical to failed parts and potential repeat failures continue. No corrective action to parts has been reported and no improvements to vehicle sensing system have been made. Ford Motor Company disclaims any responsibility for damages except those covered under initial vehicle warranty or those covered under extended warranty. If warranty does not cover failure of electrical components then Ford Motor Company will not cover collateral damages ( failure of cylinder head spark plug threads). Ford Motor Company published internal technical service bulletin to repair facilities that requires use of oscilliscope to determine if electrical part is experiencing problem. Ford repair facility refused to return damaged cylinder head and faulty coil-on-plug assembly stating that they were required core returns.

Each time tomball Ford has repaired the vehicle and the last two times I have had to pay for the repairs. I would like Ford to recall the ignition coil on this model and pay for my repairs.
