Question

Answer
Hi Sundifu!
The circle with exclamation mark (actually gear with exclamation mark) means that the EGS (transmission control module) has detected a fault in the transmission system.
If the broken stabilizer link did not damage the cables of the wheel speed sensors,then I suppose that it has nothing to do with the DSC light coming on.
I think the power loss has affected the coordination between the engine, transmission and abs/dsc (thereby setting off the dsc  and transmission checklights). Funny, you never mentioned that the check engine light is on considering that you say there is a loss of power.
Have the DME(engine) faults read by a good OBD2 scanner
(try the free scanning offered by Autozone). Once you get the results, you may decide to reach your own conclusions and proceed with repairs. Or, you may want to tell me about it and get my 2 cents worth of advise.
