I found one documented case.

Related to a failure not a common fault

That incident was caused by a failure of the mechanism that prevents
reversing of the horizontal stabilizer acutator from its set position.
It was not a runaway trim incident as such. It was more a slamming of
the stabilizer to its limits due to a failure of the actuator, not
the uncontrolled operation of the trim motor.
