Filed Aug 13, 2023 · Steering, Suspension · CA

At the moment, the vehicle is releasing a strong order smells like burning oil or gasoline. It’s coming from the rear of the vehicle. You can smell it immediately when you step out and in the car. The rear is making a loud cranking noise and starting to shake. It appears based on the information that it’s a huge possibility it’s my rear differential going out. It posses a threat due to the anticipation of the brakes locking and causing a serious accident to my family or other on the road. Ive taken very good care if the vehicle and done all the required maintenance on the vehicle. Went though GM motors repair shops

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.

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

Purchased car from dealership in oct 2015. While driving, I begin to smell burning oil and noticed oil leak under vehicle on left side. Took it to a mechanic to see where leak is coming from and he stated that valve cover gasket is leaking oil out as well as oil is present in the spark plug reservoirs. Will have to get gaskets replaced before further damage is caused. This seems to be a common problem with this model vehicle and I recently saw on news where gm recalled other models and years of vehicle with same issue. Why wasn't this model cadillac included in the recall when is should have?

For the last year my car has ran badly. Very rough idle, engine light throwing multiple codes, bad gas mileage, heavy oil consumption, and pulsating throttle while parked and driving. I've taken it to the dealership and for an entire year they've given me the runaround. On monday I took it back in to rancho motor company in victorville, california and they finally say it's the timing chain. The recall warranty voided at 120000 miles. Now they refuse to honor the recall. My car is dangerous to drive.

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.

Leaking valve cover gaskets resulting in oil on coils, oxygen sensor and risk for oil related fires. The smell of burning oil is prevalent because of oil on hot engine parts. A review of various internet forums shows this is a common problem on this make/model. A consensus opinion appears to be the valve cover gaskets were made from inferior materials. Since this is a fire safety issue and/or a result of the manufacturer's negligence, this car should be recalled.
