The Vin No. 1G1YL2D74E5106354 The dealer is Burns Chev in Rock Hill SC. I heard a very loud grinding noise at about 500 miles, pulling away from a stop light, I had the top off and music on, everything seemed normal, no indication of anything abnormal just the noise, very loud. I went to a local chevy dealer Carter Chev in Shelby NC for an oil change and told them about the noise. They dismissed the noise said could not duplicate. Also, they called me as soon as I got home and asked me to check my oil. They said they thought that it might be low. It was, three quarts low. That prompted a letter when they sent me a survey. Anyway, I kept hearing a ticking noise when the car wanted a skip shift when I went to 4th gear. And out of nowhere the other morning when I started the car it made a loud ticking noise when pressure was applied to the clutch. The night before, there was no hint of a problem when we put the car in the garage.
