Go get it replaced. Same thing occured on mine and it eventually stopped playing CD's all together. Just got it replaced (Under Warranty) a couple of weeks ago. Don't wait for it to break because it took my dealership 2 weeks to order, receive, and replace the damn thing! I felt lost without my CD player!
