I cannot believe that GM would build a Cadillac without a sensor to let you know that the oil is low. The other reviews sound like me. Had I know that the SRX V6 uses so much oil and there is not a light that tells you there is no oil in the car I definitely would not have bought it. Driving from LA to Sacramento the car starts jerking but no warning light comes on so I think I just filled up with bad gas and continue to drive another 100 miles. Well it was not the gas it was no oil in the engine. I owned the car 4 months and was scheduled for an oil change two days later. I cannot believe GM does not fix this problem. The warranty does not cover engine damage due to no oil in the car.
The navigation system, DVD player, and sun roof.
Put a low oil sensor on the car. I buy a car every 3 years and never in my 47 years have I ever had a car run out of oil.
