I would say the GT350 engine issue. But that's because I know of more cases on a personal level, which can be chalked up to knowing more Ford/GT350 people than Chevrolet/Corvette C6 Z06 people.

A personal friend of mine is replacing his motor for the second time now. Pretty ridiculous.

The Z06 valve issue was a manufacturing issue, not the design of the engine. I haven't followed the GT350 issue too much...

The Phillips-Head Screw

Worse than the worthless slotted design? I'll take a Phillips all day over a slotted.

Ford always seems to have a lot of grenading engines but I've never experienced it first hand not met anyone who has themselves.

5.4 Triton
New 5.0 truck engine
5.2 Voodoo

Basically every Ford diesel truck engine.

OP, I voted GT350 here. C6Z valve issue is an easy fix.

Phillips isn't bad if you get the correct number bit to match the head profile. It's harder to strip a flathead with the incorrect bit than a phillips. The worst auto-feed systems I ever worked on were phillips. Torx is my favorite by far.

And what profile do we grind into a phillips when we inevitably strip one out by looking at it the wrong way? One big slot. :)

For real though......
Mixing metric and standard fasteners in the same equipment.

They need to invent a new method of torture for engineers that do that crap. I fired a guy one time who kept doing that out of sheer laziness. Our engineering standards dictated metric fasteners, but our CAD system had SAE as default (we kept requesting PTC give us an option to change it). This dingus would only use metric if it was already established in a model, so we had M6x1 here, 1/4-20 there. Sometimes he'd sneak in a fine thread, or somehow managed to get non UNC/UNF threads altogether. I stuck him on detailing duty until he pulled two stunts on the same day and I had to let him go.

Well, you could say Challenger was not an engineering screw up. If they had listened to the engineers, it never would have been launched. And Columbia was more a political screw up. The foam failed because the brass insisted a new foam be used because it was "green." I do see your point, though.

No argument on the other two, at all!

Torx is best. When I install a puppet ruler of the world, the first thing I'm going to have him do is make a law banning everything but Torx.
