Count me in too guys. Just experienced this over the weekend. Car in dealership now, they will need to replace my transmission valve.
Purchased in March/April 2013 - 2014 CX-5 GT with just over 10,000 km.
Symptoms are exactly what the previous post describe.
Just picked up my 2014 2.5L AWD last week, first tank still. Only 10.5L/100KM average. 50/50 city / hwy. Maybe still need to break in, not too impress so far.
Never gone higher than 3000RPM. Just driving normal.
