05 SXT clutch?

Has anyone had a problem with the clutch slipping on cold days? Mine seams to slip when it’s cold but after the car warms up its fine. What’s strange about this is the fact that it doesn’t do it every time, some days even though it’s cold it runs fine. I was just wondering if it might be a sign that there’s a bigger problem coming. I have 35,000MI on it right now and I would like to find the problem before the warranty runs out at 36,000MI. any help would be greatly appreciated.
