Self-oscillations are the result of an efficient mechanism generating periodic motion from a constant
power source. In quantum devices, these oscillations may arise due to the interaction between single
electron dynamics and mechanical motion. We show that, due to the complexity of this mechanism,
these self-oscillations may irrupt, vanish, or exhibit a bistable behaviour causing hysteresis cycles.
We observe these hysteresis cycles and characterize the stability of different regimes in both single
and double quantum dot configurations. In particular cases, we find these oscillations stable for over
20 seconds, many orders of magnitude above electronic and mechanical characteristic timescales,
revealing the robustness of the mechanism at play
