Brake Light problems of the 2007 Cadillac CTS

I am the owner of this 2007 gm product. I took my car to frankel Cadillac 1/09/15 , invoice number 60596 and I was never notified that there were recommended recalls on my vehicle. On that date there were some problems related to the wiring on the abs and ebtm and I denied the service to be done there because I was quoted a cost of over 2,500 dollars and I was informed that it might escalate to 3500 if an abs pump needed to be replaced also. I later had the work done at young's located in woodlawn for a lot less. I now problems with the power train and the anti theft system and have the auto in gregg's repair , 5050 wabash Ave. I also saw on line that the on star operation is able to release the anti theft mode. I have been quoted a price of 886 dollars plus change by gregg's Cadillac . I am able to drive the vehicle, but in order to get the key out, the battery has to be disconnected. I am perplexed that I was never notified about the recalls on this vehicle. With all of the noted problems I was in motion. I was stopped by the police for the brake light in the city and I was driving on the highway when the anti theft mode went into operation.
