I just got my Cobalt (base) at the end of August, and it has about 2000 miles on it. I've recently been having some problems with the transmission. Whenever I drive in reverse for a bit, park for a minute, and then try to put it in drive, it just hangs there, revving in park, even though it's clearly in "D". The only way to get it to move is to put it in reverse and then back into drive. Going from drive to park won't seem to fix the problem. I've had it happen twice already, but it never happens when I'm trying to show it to someone. I think the guys at the dealership won't believe me if doesn't happen in front of them. Also, my CD player seems to be on the fringe lately. It'll just display the track number when I start the engine, and won't even eject the CD unless switching over to the radio first, and then switching back to the CD player. When it finally does eject it says "none." It'll work most of the time, but working all of the time would be better. Would it be worth getting these things looked at (while it's still under warranty)? I don't really want the guys at the dealership to just make things worse by trying to fix these things. Any comments/advice? Has anyone else been having any similar problems?
