There is a strong smell of what I could only at first describe as natural gas or propane (rotten eggs) entering the cabin. It was compounded when I put turned the cabin heat on. With winter upon us the smell enters the heating ducts making it nearly unbearable. Furthermore while driving under normal acceleration on a minor road there was an audible pop (as if a hose beneath the engine came off) and a fluttering noise with loss of power. I am assuming a turbo or waste gate hose came off on its own. Once the hose popped off the smell was undeniably singed motor oil. After 30 years of doing oil changes I can assure you it is the smell of burning motor oil. I have seen many such odor complaints on the 3. 5 litre eco boost turbo. There is definitely a problem affecting many if not all turbo eco boost engines. Please investigate this dangerous noxious singed oil odor. I purchased this vehicle in may 2017 as a certified used car, it is currently in the dealership for repair. I am available to assist in any way to help with the investigation. I am an owner of a vehicle with the takata recall, this condition and nauseating smell is far far worse. Please help.
