Where to start? If you are having oil leaks, then there should clearly be a point of origination under the vehicle that you could see. Right? But the dealer does not find them?
The transmission issue is odd and may not be duplicated at the dealer if it is intermittent.
Rollback is noted and discussed in this forum. That is an annoyance and not a defect in my opinion.
Paint issues? Personally, my edge has an excellent paint job. You should post some pics to back up your paint claim. Before I buy a vehicle, I always inspect for paint defects like acid rain spots.
Fumes and coolant? Do you have antifreeze on the ground? A dealer would definitely correct this quickly even if in the heater core.
Not running smooth and pulling. Some Edge owners report a pull and it is discussed here.
No offense, but you sound like the kind or owner that is looking for issues and piles them on. Dealers absolutely hate customers like that. They see you as "over-the-top" and unreasonable. Just reading your first post leads me to this conclusion. I would suggest going to another dealer and working on one problem at a time. Get under the car, dins the oil leak (if there is one) and take it for repair. Good Luck.
