Engine stopped running. Would not restart. Had to have vehicle towed to authorized Cadillac service center (green Buick GMC, davenport, ia). Green replaced parts (throttle body, part 9128412, connector part 15306420, seal part 90412566) with new ones and then cleaned, at a cost of $1,425.82. To be fair, in retrospect, green should have cleaned old part to save customer unnecessary costs. Now, three years later, this expensive fix is needed again. According to lujack northpark auto, davenport, Iowa, (invoice no. Cvcs863235) date 05/05/14, milage: 113716, these parts need to be replaced again already. (48000 miles later) that means that the $1,425.82 we paid to green was lost to either inferior quality parts (planned obsolesence) or sabotage by the authorized service centers. This car was in lujacks three times this year. Twice their technician removed & replaced V/C & vit gaskets. (parts vs50628R & MS96103. See cvcs854609 & 855596) which means removing these parts. GM refused to make any good faith effort at resolving issue (see GM file # 71-1305208758) updated 11/24/2014

Tsb 05-06-01-007A this has happened to my cadi on at least three occasions. First time, Cadillac dealer charged to replace thermostat. Didn't work. Next time, repair shop replaced oil gasket. Didn't work. This time I found the below description on line and will ask my repair shop to fix. If this is recurring to Cts owners, there really should be a recall. It is also a fire hazard. Irritating. My research found the below and it is right on target.....it rarely happens because it is rarely below 10 degrees in my neck of the woods.... the car involved was a 2003 Cadillac Cts. Started vehicle in approximately 7 degree weather. After starting vehicle and running for approximately 15 minutes notice severe power loss. Within next couple of minutes black smoke with extreme burning smell flooded vehicle interior compartment also smoke starts to come from under hood of vehicle. Pulled into safe location found huge oil leak on left side of engine around valve cover. Could have possibly started a fire due to highly combustible oil being blown on engine but luckily did not catch on fire. Check on-line found tsb 05-06-01-007A stating GM knows this is a problem. "when operating in extremely cold weatherconditions, some 2003-2004 vehicles with 3. 2L V6 engine may leak engine oil from the cam/valve seals, especially from the left side just below the oil fill hole in the cam/valve cover. " this is quite a bit more than a leak since approximately a quart of oil was blown on the engine in only a couple minutes. If the engine would have been hotter there could easily have been a fire. Since this is a know issue with a known cause shouldn't this be taken care of by GM or at least the safety of the drivers and passengers should be considered. It could have been much worse if the vehicle would have caught fire.

Starting around September, my car would randomly shut off while in motion, at various speeds. After hundreds of dollars in diagnostic fees, I found some Cadillac forums stating it was a crank shaft sensor malfunction, which is common in 2003 models. My car would also show the traction control was off with no warning, and not get out of gear while being on, with no warning as well. The computer system would show low oil pressure and other warnings although nothing was wrong. And lastly, at around 78,000 miles, while driving 70 on a highway, the car make a huge bang, and smoke erupted, almost causing me to crash on the highway. All the oil leaked out, and the car won't start. I'm being told to replace my entire engine because of a possible head gasket, which according to multiple forums, tends to be faulty in the '03 models. These should obviously be recalled if so many cars are affected. I'm paying over 5000 dollars in repairs and costs for this. I refuse to ever let anyone I know, as well as myself, purchase another Cadillac, unless this gets resolved.

As I was driving down the highway, the stability control light came on, then the brakes seemed to jerk a little and the car lost most of it's power. I had a mechanic test it, and they said they couldn't find a reason for it. The stability control light stayed on, but I didn't seem to have the problem again until about 2-3 months later when I was going 70 down the highway, lost all power and the motor shut down. Cadillac would not restart, had to have it towed over 2 hours back home, only to find that this time the timing belt had broken and the motor is blown since these cars have interference motors which causes the valves to get bent when the timing belt breaks. I am now without a vehicle and was almost in 2 accidents due to this. Another issue is the light cover from the lights on the trunk came off in the car wash and broke. Apparently this is a known issue yet Cadillac refuses to fix it. Their adhesive was not strong enough to hold on the plastic. This was my first Cadillac, and will be my last. They are dangerous and they refuse to fix their failures.

I was driving down the highway and all of a sudden the vehicle lost all power. I was almost hit by the cars behind me. The timing belt had broken, and the motor is now blown due to the valves being bent. This was not only dangerous for me and my family, but is very very costly. I had previous issue with the vehicle losing power once while driving, also almost got into accident, but the mechanic could not find the cause. This was about 3 months earlier. It only happened on the highway going between 60 - 70 mph. This is so dangerous! I was over 2 hours from home, and had to pay a ridiculous amount to have the vehicle towed back home.
