It's not that i'm mad, this is just a bummer .
 I kept my 1994 Lumina APV over my 2001 Venture because the Venture was an absolute piece of junk. It had a major list of problems. I had only always bought Chevy's, but that Venture ended it for me. So i buy this Mazda5 and seem to have an issue with it right away. So i'm not mad, just bummed and kinda laughing a little.

So brace yourself, there's a list of things you will experience in the next 12 month
 
* Cracking noise from the base of the windshield when it is cold
* Body vibration at 50mph
* Uneven tire wear -- the rear wheels sit like this / \
* Rear suspension noises when cold
 
Motor mount and rear shock failures are also reported.
 
Good thing you got rid of the Venture. Watch this:

How's the rear main seal on the APV?

Ouch!!! on the youtube.
 The suspension seems really stiff and already creaks in the cold. And i can already see the back tires set like this "/ \". Like it's sut-up like a racecar. HMMMMMMMMM. Did i get a Mazda flavored Lemon?

Mileage update! Probably 75% highway travel on this tank, drove 237.7 miles and it took 10.24 gallons.............23.2 MPG

sbsteggs, yes i am getting the mpg that I wrote. I would be very disappointed if i were experiencing what you are because we got rid of our older minivan for similar reasons like yourself.
 
All I can add is that I do not let the vehicle warm up in the mornings, perhaps only about 30-45 seconds max, but that should not matter regardless. This morning as I write this it is 18 degrees out, and I would bet you are not that much colder there.
 
If what you mention in the above comments is correct then clearly something is definitely not functioning as it should on your Mazda, and I hope the dealership can fix this for you. Could you have received bad fuel somewhere? This is a LONG shot but I wonder if the oil is ok ~ possibly somehow it is contaminated or lost it's viscosity in someway? The same would apply for the transmission fluid? I realize that this is FAR out there for possible explanations.

On a last note, when I fill up in never "top" off the car with fuel to get in that last gallon in (I read that is not recommended to top off your car). When the pump stops, that is it. If you are consistent on how you fill up then the mpg numbers will not be effected, this just came to mind. Perhaps sometimes you top off the vehicle and sometimes you do not?? If this is so then that extra gallon of fuel may be the culprit here?

For me to narrow down the cause I would.
 
1. Check tire pressure
2. Ask where you get your gas what the octane rating it and the amount of ethanol.
3. Check the air filter
4. Check all fluid levels
5. Check the brakes to ensure they are not dragging. That goes for both normal and emergency(hand) brake.
 
   I would then, after checking the above, wait for a non raining / snowing / not overly windy day then fill the tank and go take a half hour drive each way on the highway on level ground using the cruise control at 55 mile / hour (90km) then return to the gas station and refill the tank. Do this on a less busy time so that other driver do not shoot you(lol) for driving that speed. Try as much as possible to fill to the same full point. Also turn off the air and do not put the vent on the defroster only setting as the a/c will still be on even though the a/c light is off.
 
I would then calculate the mileage at that point if the figure is not very close to the best company rating then there is something amiss.
 
ps their is not a real difference in mileage on dry conditions from winter to summer. the difference is negated by the fact the temperature of the gas is lower in the winter and so is more dense so that even though we will use more gas to heat our cars it all comes out in the wash. they used to tell you at what temperature the price was calculated when purchasing but they tend not to show that on the pumps any more.
 
Just a suggestion.

The heat used to warm the interior of the car is waste heat, once the thermostat opens -- a few minuets after start-up. If it weren't used to heat the car, it would be lost through the radiator. There is no added cost.
 
Air density does increase in the winter, as the temperature decreases, which means more wind drag.

Just kind of dawnned on me, but by any chance are you running a different tire size then what it came with stock? Can it be that your odometer is not functioning correctly or not calibrated correctly? .....Just a thought.

The tires are the tires from the dealer. Hopefully they check the calibration to the odometer.
 I got a feeling the problem is in the brakes. They often squeak, and are extremely touchy. They may be dragging. I'm not a rocket scientist, and can hardly even speeel rocket scientist, but if the brakes are grabbing that probably would have a heavy impact on MPG.
 I take it in Wednesday (tomorrow) morning. I'll keep you all posted and thanks muck for your thoughts and input.
