My wife has a 2003 CTS. She has been having intermittent problems starting the car. It will not turn over sometimes. You have to try several times before it finally turns over, and starts. The battery is less than a year old (I haven't tested it). I have removed the cable connectors from the battery and they were clean and tight. It seems to happen more often when she is at work when the car is sitting in the hot sun all day (she says). When you turn the key there is nothing (no click or sound). You have to try several times some times and it starts right up. It doesn't happen all the time, but it needs to be addressed before it breaks down completely. Car is garaged when the wife is'nt at work. It has around 125000 miles. I have kept up all the scheduled maintenance on it.

Removed Battery cables and checked cleanliness and tension.
More often than not, this complaint turns out to be caused by a faulty starter. Lacking the ability to accurately diagnose it when it acts up (testing it when the car actually starts won't reveal the problem), I think I'd take an educated guess and put a starter in this car.
