“The transfer case is leaking and going to go completely out on my 2012 Mazda CX-9, I noticed the same gear shifting problem in my 2004 Mazda 6 wagon. The car feels like driving a stick, it jolts when shifting to drive and while moving it feels like it is shifting early. This is a known problem with Mazda but a recall is yet to surface for this issue.”
NHTSA complaint #11093736, filed 2018-05, 58,000 miles“I was turning right into a parking space with my foot on the brake, when the car suddenly accelerated. The engine revved up and the car darted forward. For a split second I lifted my foot to make sure I was not pressing on the accelerator, and immediately pushed back down on the brake as hard as I could; the car continued to speed forward. Instinctively I kept the wheel turned to the right to avoid crashing into the building in front of me as the car jumped the curb, but I hit 2 parked cars. …”

And the dealer can't find anything wrong with it. 1. The AC always comes on. Even when it's below zero outside. 2. It fails to go when pushing on the accelerator frequently, and especially in reverse, from a stopped position, until you really push hard on the accelerator causing it jump. 3. Last friday 2/21/2014 as I was on a ramp moving from one interstate to another, the engine continued to rev up even after I let off the gas, and pushed the brake. …”
