Loud Popping Noise and Misfire Experienced on Ford E-350

The spark plugs may become dislodged from the cylinder heads. A loud popping noise can be heard and a subsequent misfire experienced. The threads on the spark plug ports in the cylinder head(s) can become stripped or missing when the spark plug is dislodged. The threads in cylinder heads may be replaced using “Lock-N-Stitch” aluminum inserts. Our technicians tell us thread replacement is performed when the vehicle is out of base warranty. Vehicles under base warranty receive a new cylinder head.

Was fixed many times but happened many times and had to tow it a few times. Spark plugs come out of place and brake the coil. When one cylinder is fixed the other one gets the same problem. This Happened so many times that it caused my catalytic converter to be plugged up and I had to change that too. And yet I'm still having this same issue.
The cost to repair it is $500-$1000. No one wants to warrenty it. It should be recalled.
