Oh I am having the similar issue with my storme which started few weeks back. I took my car to ASS
2 times. At first they could not tell what it was. At 2nd visit after careful examination they told me that its due to clutch release bearing and its normal. And when I asked them to solve it, they said that to change the release bearing they have to change the entire clutch assembly as release bearing comes in set with the clutch. My strome has run only 25,000 kms and the clutch is still so light, so they advised me not to change it yet. So I plan to drive some more kms and change it later on.
