car   Electrical System problem 1
Failure Date: 09/05/2014

While entering the highway at about 50mph I noticed well into a left veering merge, that my vehicle engine had shut off. All the accessories were still running as far as radio and air conditioner while the battery light flashed on the dash. My steering wheel locked in a cocked position as well as losing the ability to stop the vehicle with the brakes. I was forced to slam the emergency brake to the floor to get my vehicle to stop before being crunched from oncoming highway traffic at 60 to 80+ mph. While also trying to avoid from being rear ended! once I finally got the vehicle stopped I was able place it into park and turn the key to the "off" position. After restarting the ignition the car seemed fine.

Purchased 2003 Cts used in 2007 with 54,000 miles. At 60,000 miles, the serpentine belt broke and destroyed engine in the middle of rush hour traffic. 30 days later coil went out and had to be towed again. Approximately 30 days after that the other coil went out and again vehicle was towed to the dealer for repairs. Currently the car is sitting in my driveway and will not start. Took to repair shop close to my house and they said the electrical system is too messed up to run a diagnostic on it. Prior to the vehicle dying in the driveway, the engine shut down in the middle of the road on two separate occasions. I lost steering and had to push it off the road. It is a dangerous and unreliable vehicle and should not be on the road. I contacted Cadillac but received no response. The car currently has only 74000 miles on it with a total of maybe 20000 added in three years of ownership mostly due to the car needing constant repairs. I cannot afford to make the payments and pay for repairs both at the same time. I do not trust the safety of this vehicle.

2003 Cadillac Cts - the backup light assembly came off in car wash. . . Dealerships are well aware of problem but say their hands are tied because of gm. They said the reason was because the supplier to Cadillac used an incorrect epoxy to build the part. Gm knows about the issue but will do nothing. Part is over $550 to replace!! one search on internet brings up hundreds of complaints for same issue. This is ridiculous. I called Cadillac and they said they would call if a recall was issued, but they can do nothing more.

Failure Date: 02/01/2006

Since I purchased the vehicle used from a calliac dealer I had experienced the vehicle would shut down when the veichle would hit a pot hole or hard bump. I had dealership and several mechanics from other garages over the years check for engine shut down. No one was able to replicate the issue. Recently the news has been discussing issues with general motors ignition problems. I went out to my vehicle and started it, put the vehicle in drive and smacked my key ring and the vehicle stalled. My primer key ring contains a large number of keys with weight to them when I would drop of the vehicle I would always leave a single key. Since the news broacast I have only used a single key and have had no additinal issues. I would like someone to address my complaint or examine my vehicle because I see no information indicating that the Cadillac mmodels are involved in this issue. I beleive that this problem is more widespraed. This stalling has happen several times over the years. On of the most critical incidents occured on a riny night while travelling in the left lane of a 4 lane limited access highway. I struck a large pathole and the vehicle stut down. Being a very experienced driver I placed the car in netural and attempted to restart the vehicle. There was no resopnse to this attempt. There was no left shoulder so I activated the emergency flashers, brought the vehicle to a stop and placed the vehicle in park. Again an attempt was made to start the vehicle with no success. The key was removed, placed back into the igination switch at which time the vehicle restarted. This incident almost caused a high speed rear end collision because I was unable to get off the roadway.
