Just purchased a 2011 CX-9 three weeks ago. Love the vehicle, but! The power train malfunction/reduced power warning light (looks like a wrench) lights up after starting the car. Doesn't do it every time, but has done it four plus times. Returned to dealer and they replaced the TBI, (didn't solve it), then replace accelerator assembly (still no luck). Going back to the dealer on Monday. Anyone else have this issue? Apparently Mazda engineers have said this has only occured on 3 other 2011's. I've owned Mazda before and really don't want to be negative about them. The CX-9 is great.
