Cadillac CTS owners have reported 6 problems related to battery dead (under the electrical system category).
Attempted to start the car while it was parked in the garage, but it would not crank and the dashboard display indicated a problem with the stabilizer. Also, the seats could not be moved, could not place the transmission in neutral, the door would automatically lock, and the lights would flicker off and on. I attempted to use brand new booster cables (positive to positive/negative to negative) at the remote terminals but stopped trying to connect from the charged battery due to sparking as though I was reversing my polar connections; at one point, I saw a flicker of flames and I never started the booster vehicle (12 volt). I had a wrecker attendant to try my booster cables and he attempted to charge with the connection directly to the battery and with the booster car started which created smoke and over heated cables. At the dealership, where the car was taken, I was told the positive cable was useless and the battery had a dead cell. This was very costly. I retrieved my car after about 11 days and parked it directly in the garage. The next day, I attempted to start the car and the same issue surfaced. Had it moved by wrecker again, and I am being told that they jumped the battery and started the car, but had not determine the drain on the battery.

The car has had 7 batteries replaced. It has been towed three times to two different dealships. When the failure occures the door lock, the engine will not start, lights will not work, the car is completly dead. The last time my wife went one mile and the lights,radio, air conditioning and doors locked and would not open. She could not get the key out of the ignition. The door was opened and the car sat for two hours. When she went back to the car everything worked like nothing happened. She drove home and the next morning the battery was dead. It was towed to the dealership and the oder of burning wiring was obvious. One week later the dealer service department called to inform me that the fuse block was replaced and the radio caused the problem. The car was leased and I just returned it with 17,890 miles. We went out and purchased another car when they said the wiring and fuse block was burnt. We just let it sit in the driveway until the lease run out.
The contact owns a 2006 Cadillac Cts. The engine failed to start after several attempts as a result of battery failure. The vehicle was successfully jumpstarted and resumed normal operation.

The failure mileage was 28,000 and current mileage was 38,000.

I am writing to report a very dangerous problem that occurred to my wifes 2004 Cadillac Cts. While she was driving to work that morning she began to smell a rotten egg type of odor inside the vehicle. She thought what she smelled was an exhaust odor. At this point she decided to return home with vehicle. When she returned she had me inspect the car, as there was steam emitting from under the hood. Upon opening the hood the source of the steam was revealed as the vent outlets on the battery. The battery was hot and was venting sulfuric acid steam. The battery is located in front of the firewall on the passenger side directly adjacent to the air intake grills for climate control system. The sulfuric steam was being sucked into the air intake of the hvac system and then being emitted into the cabin via the vent system. My wife had inhaled this caustic gas for the period she drove the car causing her to have severe respiratory distress requiring an emergency room visit. She was treated for severe respiratory irritation due to exposure to the caustic gas. The symptoms and illness from this exposure lasted 8-10 days and included a number of follow up visits to the doctor. At this time there has been no definite cause or reason to why the battery failed. A certified mechanic said that the battery probable had a major plate failure and went into an internal, dead short circuit causing the overheating. I want to warn/document this incident as a dangerous threat to the occupants of 2004 Cadillac Cts and other similar models. My concern is that this problem may occur to others and someone may die due this poor design. Gm patented the design of the battery and making it a dealer only replacement part. This demonstrates their responsibility for the battery design and location in the vehicle. It appears that they are negligence in providing safe vent path for the battery in the event of such a failure.

2002 cadallic ctc has not truck key lock. Adverse conditions occur when the battery fails as all, and I mean all systems shut down. One cannot get into the trunk,use the phone, or even get the keys out of the ignition. But, not having a key lock for the truck is dangerous and unsafe.
