Automatic Transmission Control Module Problems of Cadillac STS

I purchased this car in January of 2010 from apple Chevrolet Cadillac located in york PA. When I purchased this car I bought it used however it still had the remaining manufactures powertrain warranty. It had 51,554 miles on it at the time of purchase. On Feb 9, 2011 I reported to heritage Cadillac in belair MD. That I had an issue with the check engine light coming on and that I want to have that take care of before the warranty ran out. When I took the car there I was told that since the light had went out before I got there, there was no way they could tell what was wrong which I found out to be false because months later they were in fact able to check it with the check engine light being off. To make a long story short, since the first incident I have take my car back to heritage Cadillac 10 times for the same problem and I have paid them $4,212. 08 (to maintain and allegedly repair the problem of the check engine light) today is November 15, 2012 and the light is still on. I have been told that they don't really know what is wrong and that they had to contact a Cadillac manufacture to get information but I will have to pay another $3,100 to fix the problem which may be fuel injectors and a transmission control module. I feel that my wife and I have been and are being take advantage of in this situation by a certified Cadillac service center. This problem should have been resolved when I first brought it to their attention when the car was still under warranty.
