Now I've had many chev and ford trucks too. Fuel pumps got changed at 200000kms. Never had any other real issues.
What's wrong with this picture? Dodge = reliable if it spits a few transmissions and a few rear ends. Ford, Chev = reliable if it only needs fuel pumps. I'd call puking transmissions and rear ends unreliable....

In fact if I had to call any if my previous vehicles junk it would be my 2000 mustang. And only because it spit out plugs costing me time and effort changing heads.
The engineer that approved that POS should be drawn and quartered.
Cost saving measure. "Lets only drill 3 threads!"
I think it was actually for installation purposes (which in a round-about way I guess ties into a cost savings of sorts in terms of reducing assembly time). The threads are at the very bottom of the hole and there is a taper above it. Basically, a machine could drop the plug down the hole and it would self-centre and would just need to be tightened. This is useful when your spark plugs are 6" down an angled tube.
Ultimately though could have put three more threads in the hole and possibly achieved the same effect but perhaps in testing this proved to give the best seating results whilst still (on paper) providing adequate thread engagement for the predicted stresses of the operating environment and required fastener torque.
