There is a problem with the MPG and it is or could be the TCS, which is being engaged when not needed creating drag. Turn off the TCS and a light comes on saiding it is off however it re-engages as soon as you take off. It should only re-engage if it detects slippage, therefore something is wrong if the light goes off showing that it has re-engaged. I have also noticed that I am getting brake noise reflecting that the system must be using the brakes to create drag causing the bad GPM. Also this is a hazard as I was pulling out of a drive way in the snow and the system has a delayed action which had brought the car to a stop and I was frantically pushing the gas pedal to get out of the on coming traffic. This is a very dangerous car and I have told Mazda this.

2008 CX-9 GT AWD My first tank MPG was 16.5mpg with 50/50 city/highway. The highway portion is mixed with daily commute congestion (30-40mph for 50% of the highway). This is slightly better than my BMW 540iA (V8 4.4L), which did 16mpg on the same route. Of course, this is no where near what my Prius does, 44mpg. Same route, same speed, same driving style. I am happy with the CX-9. This vehicle really shows what Mazda can do if they really try. Bravo! |

I've been getting 15.5-16 mpg for my tanks (usually not a full tank, as I fill up on the days that they usually raise the price, whether I need it or not). My usual driving is about 60/40 highway/city. Generally about 77 mph on the highway. Today I had to drive 200 miles total, 95% highway. 19.9 mpg. I filled up before leaving, and again when back. Most of the highway driving was between 70-80 mph (not all, because the roads were still bad from our snowstorm for the first part). my fuel gauge was between 1/2 and 1/4 tank (closer to the 1/2, didn't see what it was exactly) when I filled back up. Also, I've noticed most of my other cars' fuel gauges go down faster on the second "half" of the tank vs the first "half" |

Replying to: jchcraig (Feb 13, 2008 8:20 am) I have been consistently getting about 15-16 mpg with mixed metro traffic. For a heavy vehicle like CX-9, if you are lead-footed, the MPG could drop very dramatically. Try to time the red light and accelerate mildly. Also check your tire psi.
