I have a 99 Grand Am SE and I can top those issues.

Three days after i drove it off the lot, Water Pump went out. No warranty was purchased. My bad. $650.00.
Five Months into ownership, AC was not working. Bought the car in January so it felt like it was working at the time. $600.00.
six months later, third gear gasket broke, lost third gear and up. I can't drive 30MPH, $1700.00.
Sporatic ticking from the turn signal/Flasher relay. Goes off when it wants to. Tested the connections on it and found that it is letting power escape through but tried a used one from junk yard, no cure. Will try a different one to see if junk yard was a bad one as well. New ones will cost about $60.
ABS and Trac Off warning lights come on daily now shortly after take off. Changed spark plugs, and am going to flush out radiator next. I too had an aftermarket cd player installed and have read on several occasions that this could interupt the electronic computer. Lovely! Not sure about the cost on that one. All i want to do is get it fixed and sell the darn thing! I fixed my plastic wheel covers using faucet washers from Home Depot, same method.
I had my coolant light come on once and I added some water to get me by for the moment. Bought some coolant and read that you shouldn't use just any coolant. The dex cool is suppose to keep your radiator from eroding as quick as the green classic. Then I also read in the manual that using the proper coolant can also help your warning lights work properly. SAY WHAT?! So here I am trying to find out more on that.
