well, in order for a proper "diagnosis" if u can call it that. u may have to be more specific. what do you mean when you say you "had trouble stopping"? as in did ur brakes not work properly, was your clutch engaged at the time? how bad was the accident? obviously not bad enough to prevent you from driving but it could have jarred the linkage to the clutch. 25,000 is not near long enough for a clutch to go out, unless you race/drive like a maniac/or let people drive it who dont know how to drive a stick. if you still have a warranty, take it in. it should be covered under warranty seeing as how a minor accident shouldnt cause anything with the clutch to malfunction. hope this is helpful
