CD Ejects Whenever I Start The Car
 

This has been a minor issue since I got the car.

If I have a CD in, when I start the car it ejects and I have to put it back in multiple times because it keeps spitting it out. Usually I have to hold the CD button down whilst I push it in to get it to stay in but even that takes 3 or 4 tries.

Anyone else experience this and know of a fix?
