Anti-theft Controller Problems of Cadillac CTS

This vehicle has had thousands of complaints about ecm related problems. Every complaint is the same. The computer causes the temp gauge, fuel gauge to stop working, the tc light & antitheft lights to come on, and the key being stuck in the ignition. It renders the car undriveable because the temp & fuel gauges stop working. I have researched this and there has been the exact same issue with thousands of cars!!! when I contacted Cadillac about this they said I would have to pay hundreds of dollars for a diagnoses fee. I told them that this is obviously a defect with poor design and/or bad parts. I have included just one of many links that owners have had with this model of car. . Read more...

This incident occurred twice. The first time (April 29th 2013), the car was at a stop light. The engine turned off by itself and the message: "anti-theft" was displayed on the car sat-nav screen. Key was removed from ignition and reinserted. After turning the key, the engine restarted. The second time (may 3rd 2013), the car was in motion in a parking lot. While pulling into a parking spot the engine turned off again. The message: "anti-theft* was displayed on the car sat-nav display. After removing the key and reinserting the engine started when the key was turned. My mechanic informed me of this website to report the incident. The car has been brought to a Cadillac dealership and I have also reported the incident with Cadillac corporate. A rep from Cadillac will be in contact with the dealer. Said that I will receive a call back between 5/6/2013 and 5/9/2013 with the options to resolve the issue.

I was driving home from work when the security light came on the dash and a "service anti theft system" message came on the radio. The entire dash quit working, radio went off, power steering stopped working and I was driving without knowing how fast I was going or what was going on. After I got the car home and parked it, I shut it off and came inside. When I went out the next morning to start it, nothing happened. The dash lights up, everything works but the gas gauge and temperature gauge, but the car doesn't start or even attempt to turn over. The security message and service air bag message shows on the radio. I was told that it may be the key so I purchased a new one from moses Cadillac and attempted it but a new message came up "ignition start disabled, remove key. " I can't do anything with it, the entire car is locked up and won't start so I can't even get it to the dealer to be looked at. When you're in it and turn the key on all the doors lock, you can hear the fuel pump start, and nothing else. The key locks itself into the ignition, I had to access the manual release to get it out of the car.

I own a 2008 Cadillac Cts with awd. I bought it in December 2007. At around 7000 miles in mid-February 2009 my car would not start. The antitheft device was activated. A roadside assistance technician came out. He said it was a defective battery which he replaced. Three weeks later I tried to start the car & received a dashboard alert that the battery registered low voltage and could not be started. The car was towed to the dealer who worked on it for two days. They told me that "maybe" the computer was being turned on when the car was shut off. Their "maybe" answer made me feel they were just guessing. They told me they had corrected the glitch, charged the battery, told me the battery was fine & that the car should be fine now. Last night, April 15, 2009 at 10:00pm my dashboard alerted me that the battery was too low to start. I called roadside assistance who could not get it started either. On April 16, 2009 at 8:30am I had to have the car towed into the dealership again. The service technician again said my battery must have a defective cell. This is the same battery that they put into the car 6 weeks earlier that they said was "fine". I am now awaiting their "professional" diagnosis. Do you have any other complaints of this type on this vehicle? also do you know if this car can qualify as a lemon under federal & NJ lemon laws?.
