They get stuck when the CD Changer is starting to get worn out.
cd player
burn the car! trust me
You need to clean the CD Changer every 6 months to ensure the CD Changer runs smoothly.
The Disc is no longer recognized as media that can be played through your player, or you eject button is stuck on.
my parents Trailblazer has the same issue, i think it has something to do with the CD player getting warm.. shut the car down for a little while to let things cool down and when you restart the car the CD should come out.
You can take it to a local mechanic or car shop and they should be able to get it out for you. I wouldn't try and do it yourself.
take the CD player apart
Try popping a credit card in when you hit the eject button. It worked for me!
Don't know how stuck the CD is in the CD player, but I used another CD to pry it up and out - worked fine for me.
I had this same problem with no luck getting it out. However, I left a tablet PC plugged in while the car was off and had to have a jump. When I started my car after the jump, the CD popped out!!! No problems since.
Not sure if this will help or not, but a CD gets stuck in my GM car about once a year. In order to get it out, I cut off all power to the CD player by removing the appropriate fuse for about 15 seconds. I put the fuse back in, push eject, and the CD always comes right out.
