 A few areas have made us not pleased with our choice. Gas mileage is much less than advertised. The car is too heavy - sluggish when passing on highway or going up hill, poor gas mileage. There is a design flaw with the doors. They are big, unnecessarily heavy, and balanced wrong. When parked level, they will naturally fall hard to a full open position. As the doors are so big, they will catch any wind and open hard. The check strap on the door is under-engineered for such a heavy door. Within 45 days, the check strap broke, the door slammed back into car body. $1500 damage and Mazda will not even return phone calls or acknowledge issue. Not happy with the CX9 or Mazda, give both a pass.
