Hello - I recently purchased a 2014 CTSV with 110,000 miles. I also purchased a warranty - which the people I bought it from flat out lied to me about and said the warranty started right away. I called the warranty company a week later and was informed that the warranty was only good after I had put 1000 miles on the car. In the mean time the car was making a humming noise and skipping under heavy acceleration. Took it into the dealer and they completed a rear end differential replacement (recall that had never been done on this car) replaced the spark plugs and a couple coil packs. Got it back and it is running much better. Before I took it to the dealer it was making is making this really strange humming noise and I noticed the fan was staying on when I turned the car off. The dealership told me the rear end replacement should fix the humming and that and that it was throwing a few misfire codes which is why they replaced the spark plugs and coil packs. The humming and fan staying on is still there along with the clicking or sound of a valve opening or closing or something. I am going to have to drive about another 800 miles I guess before I can take it in for anything to be covered under warranty. No check engine light is on and like I said the car seems to perform fine. Could this be a failing intercooler pump? When I turn the car off you can hear whatever is turning off, winding down. I love this car, it is the car I have always wanted but I hope I have not bought something that is going to require huge repairs. I financed the car and cannot afford any costly expenses that will be $1000's of dollars.
