I replaced the spark plugs in my wife's 2012 Ford Focus at odometer reading aprox. 100,000 miles.
30,000 miles later during a trip out west it started to misfire.
A Ford dealer "York Nebraska" found 3# plug had come loose. They replaced all four plugs.
10,000 miles after that #4 plug blew out without so much as a misfire leaving no threads whatsoever.
The cylinder head had to be replaced. Nearly $2800.00
I went on line to see if this problem has been prevalent. I guess I found my answer.
I am a mechanic by trade. Industrial maintenance the last 20 years and an auto mechanic before that for 13.
I just double checked the tightness of the plugs I installed in our 2006 Milan 4cyl. and they are still tight.
