4 Brake Light problem of the 2006 Cadillac CTS

Failure Date: 07/01/2015

My back center brake light no longer works and since this was pointed out to me earlier this month, I have noticed at least four other Cts cars with the same issue. They range from my year ('06) to at least 2009. And when quoted a price ($600+!) I balked at having it replaced. Anyone else notice this or have this issue?.

5 Brake Light problem of the 2007 Cadillac CTS

Failure Date: 01/09/2015

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.

Failure Date: 11/18/2009

The exterior back brake lights fell off my Cadillac Cts 2003 model. I have noticed a majority of the 2003 Cts models have the same problem. It's a shame Cadillac would not be responsible, the vehicle cost me over 30,000. 00 after its paid for, they have no concern for the condition of my vehicle. It really makes Cadillac look awful to have that many vehicles in the same condition. I will not purchase any more Cadillacs.
