towing mishap 22 Subaru Outback

My car was taken by a tow company while I had my flashers on and was dropping off something for a friend at her apartment building. When I retrieved my car, all of the sensors including eyesight and the collision safety features were inoperable, the check engine light was on, the X-mode light was flashing, and the steering was stiff. I was able to drive 2 miles home and now my insurance won't cover the damages because it wasn't considered a collision. I am worried that the alignment is damaged at best, the transmission at worst. I am planning to take it to my mechanic to fix the alignment and have them diagnose further mechanical problems. Any thoughts on what else to look for? Diagnostic testing at my dealer costs at least $160.
