LEGO Set Missing Pieces? Here’s What Really Happened and How to Fix It

So you just opened your brand-new LEGO set. You sorted the pieces, followed the instructions step-by-step, and suddenly realized something’s off; you’re missing a piece.

It’s disappointing to get so far into a build only to find you can’t finish it because a piece is missing. Especially if you’ve never had that happen before, you might be wondering: Why is my LEGO set missing pieces?

Let’s break it down.

Is It Normal for LEGO Sets to Be Missing Pieces?

LEGO Pieces

No, it’s not common. LEGO is known for its excellent quality control. Missing pieces in brand-new, unopened sets are extremely rare. When it does happen, it’s usually due to a minor packaging error.

Sometimes, the piece isn’t actually missing — it might be:

  • Stuck in a bag corner
  • Hidden inside another larger piece
  • Mistaken for a similar-looking piece
  • Dropped or rolled away during the build

Always double-check the bags and your workspace before assuming it’s missing.

What to Do If Your LEGO Set Is Missing a Piece

  1. Check Thoroughly: Go through every bag again. Shake them out, check corners, and inspect the area where you’re building.
  2. Still Missing? Contact LEGO: If you’re sure a piece is missing, LEGO’s customer service is known for being helpful. They’ll send you the missing part — completely free.
