Springlock failure
These incidents occur when the locks, that are holding the endoskeleton in the folded position, break. This causes the endoskeleton to spring into its usual position, anyone caught inside the suit when this happens will be impaled and crushed by the parts.
What happens if you get Springlocked?
You will die, but it will be slow. You'll feel your organs punctured, the suit will grow wet with your blood, and you will know you're dying for long, long minutes. You'll try to scream, but you will be unable to: your vocal cords will be severed, and your lungs will fill with your own blood until you drown in it.”
Can you survive getting Springlocked?
That limb would be damaged beyond repair, but they'd live. TLDR: Short of a head or torso springlock failure, someone could survive.
