Engine Mounts on 2005 Acura TL

Engine Mounts broken. Spotted during routine maintenance. Car was in an accident prior to the last maintenance.
Could this be the cause. Ins. Co says it could be wear and tear. Anyone else have this problem.

Could be either one. If the mount was broken during the accident, it should've been detected at that time so the insurance company could cover it, but now it is probably too late.
