3 Engine Oil Leaking problem of the 2006 Cadillac CTS

Failure Date: 09/30/2013

Engine has used one quart of oil every 800 to 1000 miles since I bought it in 2013. No smoking, no leaking. Just disappears and no way to know where it went. Only had 38,000 miles on it and has 85000 miles on it now and still does it. Told by one place that general say it is normal for that car? don't believe that. . Was almost empty be time I was having problems and checked it. I had put 3000 mile on then and did not expect a oil loss like that. Have kept eye on it not to get that low since.

4 Engine Oil Leaking problem of the 2005 Cadillac CTS

Failure Date: 03/07/2013

A few weeks after my latest oil change I was driving on the freeway in semi crowded conditions when the car started bucking. The car slowed and I had to avoid traffic and almost was hit as the car would not respond, was scared to death. I thought it was a transmission issue but when I called the mechanic he knew what it was right away, he said check your oil and I did and it was near empty. No oil in my garage, no oil in my work parking spot, no visable leaks, but all the oil gone. It just happened for a second time and when I looked for complaints on the car it is the same issue time and time again. How is Cadillac not held responsible to the driving public for this safety issue. How many must die before it is recalled?.

6 Engine Oil Leaking problem of the 2003 Cadillac CTS

Failure Date: 09/20/2012

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.
