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?

What owners say
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.
Oil leak from frozen pcv valve and valve cover gasket. Causes oil to leak onto engine and exhaust and fumes from burning oil to enter into the cabin of the car.
Tl*the contact owns a 2003 cadillac cts. The contact stated that the pcv passage froze and caused oil to spill onto the exhaust. He called the local dealer and was informed that the pav passage was faulty. The dealer redesigned the pcv passage in the vehicle. Three months after the repair, the pcv passage began leaking again. The contact called the manufacturer about the leak, but has not received any feedback from the manufacturer or the dealer. He feels this is a safety issue because the burning oil leaves a toxic smell in the vehicle, and the leaking could cause the vehicle to shut off. The current mileage was 67,000 and failure mileage was 66,164.
2003 cadillac cts, no sevice lights on, when stopped at light, smoke coming from under the hood, then smoke inside of the car. Turned off engine and assistance opened the hood, flame under hood and smoke from fire near battery. Was told that pvc valve burst under pressure from cold outside temperatures, caused oil to spray over engine and under hood and because engine was hot from use, caused it to ignite. Also told that this was the 3-4th car reported last week to one dealership with same problem. Not sure what repairs were done, car is repaired today.
