I have a 2010 Hyundai Tucson with 5-speed manual transmission. When the engine is cold, there's a loud but brief grinding noise when starting up as the clutch is released. It's been suggested to me that it may be the clutch-release bearing. Is that likely? The clutch (including the release bearing) was replaced just a year ago. When the engine warms up, there's no longer any noise. Starting in second gear isn't different.
