In this study, the properties of oscillatory dissipative solitons (DSs) in a cubic complex Ginzburg-Landau equation stabilized by nonlinear gradient terms are investigated. The main finding is the transition to dissipative solitons with spatiotemporal disorder, which occurs as a function of the diffusion coefficient. This transition proceeds via quasiperiodicity and is accompanied by the emergence of incommensurate satellites next to the fundamental frequency and its harmonics, suggesting a possible route to localized spatiotemporal chaos. The transition back to oscillatory DSs follows a similar scenario.
