I've played for more than 100 hours, nothing stop working so far, but does it happen?

The answer is no and yes. No, parts don't break randomly, unless you install a mod. Yes, parts randomly break if you drive/fly recklessly.

I'll start with NO because that's easier: Parts don't randomly fail in the same that Elon Musk's rockets do. There is a mod called Dang it! that can be used to simulate what I call "SpaceX mode" that will cause ...

...parts on your ship to fail randomly, and you will need to repair them before you can use them again. Be careful... some failures might be relatively harmless, but others might seriously ruin your day. The more you use a part, the less reliable it will become: so don't be too throttle happy with those mainsails!

Dang it mod for KSP

But unless you have that mod, parts won't randomly fail.

Now for YES part:

Sometimes, moving parts can move into other parts (it's called "clipping") and it can destroy parts - especially solar panels and landing legs. I've had this happen to me on my current mission, I have solar panels that are stored in a service module... something went wrong and now the panels won't extend.

Broken Landing Leg

Also hard impacts and high speed can break parts - especially wheels. But if you've been playing for 100 hours, you know that.

Broken wheel


Yes it happens. Sometimes more than others. KSP has never been 100% stable.

  • I read the question as asking about deliberate equipment malfunctions, to model the occasional unreliability of real rockets and spacecraft. (AFAIK, nothing like that is included in stock KSP, although I'm sure there's a mod for it somewhere...) Commented Nov 1, 2015 at 14:51

No, in terms of game simulating random rocket hardware failure.

Everything works perfectly in stock KSP. Though if you're looking for some, there's a mod called Dang it!
