I was traveling approximately 65 MPH on a 3 lane highway, while mainitaning a constant speed. Suddenly all power to the vehicle cut off including my power steering and braking. In a panic as I as coasting I was fortune enough to weave my way across 2 lanes to the side of the highway and roll to a complete start. After gathering myself I turned the ignition from the run position to off. I looked up and noticed there was smoke coming out from under the hood. I jumped out, lifted the hood, and heard popping and steam/smoke rising up from underneath the engine by the firewall. I pulled the oil dipstick and I was about a quart low, and it looked normal. I waited about 30 min and checked the level again with the same result. I then tried to start the vehicle and there was not response at all. I was unable to roll up my windows, and there was no power to display any information on dash. When my wife arrived I hooked up jumper cables and after a while I was able to turn the key forward to see the instrument panel. It said my battery was at the correct volts, and there were no warning lights on my dash. When I turned the ignition to start. My dash flickered rapidly and there was a clicking noise but the engine made no sound as if it was trying to turn over. So I called tow truck and got towed to my house. The vehicle was purchased by me in 09 with 32k miles. It had an issue where it was eating up to 4 quarts of oil every 1k-3k miles. I had purchase an extended warranty so bye 50k miles they tore apart engine replacing pretty much the entire engine. The car currently has less then 20k miles since warranty rebuild and I am at a loss. I put a new battery in it and that has done nothing to help. Still just makes a strange clicking noise. I have no idea what to do now. It is a 2005 cts 3.6l base automatic transmission

The car has unbelievable oil consumption. I was traveling from illinois to iowa to visit my father. During the first 4 hours, I had to add 4 quarts of oil. Than 20 minutes from our destination, we hear a pop, the car stops running, no brakes and I am doing 70 MPH in the left lane with no power steering. I luckily get the car to the right side of the road. Called a tow truck and tow it to a mechanic who tells me I need a new engine. Upon researching any issues with cts, I find numerous blogs with customers with the same car and issues. Many of who complained to cadillac. Why has the manufacturer not done anything to correct this, notify customers and prevent any injuries or worst a potential death. What are they waiting for? They know about the blogs because their representative was on there after someone suggested a class action lawsuit trying to defuse the situation.

This car has had several issues the newest being it started using excessive oil just after the main computer was replaced. This car has had regular maintenance at the proper times and never used a drop of oil. When it started using oil it used five liters of oil in just 24 days or 2000 miles.
