  We study the thermoelectric DC conductivities of Horndeski holographic models
with momentum dissipation. We compute the butterfly velocity $v_B$ and we
discuss the existence of universal bounds on charge and energy diffusivities in
the incoherent limit related to quantum chaos. We find that the Horndeski
coupling represents a subleading contribution to the thermoelectric
conductivities in the incoherent limit and therefore it does not affect any of
the proposed bounds.
