CRV is not a safe car

Brand new vehicle.  Owned it a total of 20 days.  The hesitation/vibration problem is noticeable (intermittent shuddering as if a wheel is out of alignment, but related to the newly designed CRV transmission, a problem common to all CRV 2015 that does not yet have a fix) but what really stunned me was a sudden extremely high rev when going down a small hill. I was braking lightly at the time. (Service told me that the transmission downshifts on hills, so, using the brake caused this. ??!!) It didn't last long, but the engine raced so completely out of control that the vehicle did not feel safe, and one had the sense that motion had seized up, although it kept moving. The noise was incredible. It didn't happen for a while, and I assumed it was due to using the brake on a hill. (I stopped using the brake on hills and noticed that the transmission didn't always downshift, sometimes it shifted UP as the vehicle gained speed! What to do...) I brought the vehicle in to service about the vibration issue over a week later, and was told that all CRV 2015 have this vibration issue and there's no fix yet. I left cheerfully enough, and driving home, the surge/rev happened AGAIN, going UP a hill, with no use of the brake. I called my salesman, and the next morning returned the vehicle to the dealership and asked for my money back, because the car is not safe to drive. He wouldn't give my money back until this problem is proven by a Honda Canada engineer on this OR ON ANOTHER CRV 2015 VEHICLE. I left the car there. CANADIANS-- I NEED YOUR HELP IF YOU HAVE THIS PROBLEM! See the CRV forum and find me there. I owned it for 20 days, a little over 1000K (500 miles). The surge/rev problem only occurred twice, on WINDING HILLY ROADS. The vibration/hesitation problem happens anywhere, but is more pronounced on winding hilly roads.
