An experience working on my Jeep Renegade inspired me to make this post.

I recently decided to replace the front grille inserts on my Jeep Renegade. These are little plastic pieces that snap into the front grill piece and give it that distinct look of the Jeep SUV lineup. I wanted to replace the stock chrome with a nice black-out look.

When I got the seven inserts, I assumed they were easily snap in place. I tried the first one, and it wouldn’t fit. It just wouldn’t. Maybe it was upside down? No. It’s right. Why won’t it fit?

After a good fifteen minutes of messing with them, I finally realized: Each one of the seven pieces fits uniquely into one of the seven spots. That is, all seven of them are unique parts for each spot. They’re not universal. If you go look up the inserts, you can see that they all have slightly different locations of little plastic tabs that prevent them from being fit in anywhere but their specific spot. They’re labeled all differently as well, like A1, B2, C1, C2, D, etc.

Why someone would design something so simple in such a bizarrely complicated way is beyond my comprehension.

What are some other car design decisions that were like this?
