there is a burning oil smell, that is so pungent it causes nausea and burning of the eyes when driving the vehicle. have taken it to 2 separate dealerships, the first told me they could not find an oil leak and i would have to deal with it. the second dealership stated that it is a valve on the back of the motor and that there is nothing they can do about it. i was told not to roll down the windows and to leave recirculate on. called and spoke to gm directly and they state take it to a third dealer and they denied my request to send a master tech to check the vehicle. i am left with driving a car that leave me nauseated and is a possible hazard to drive.
