I recently bought a new 2009 Toyota Sienna two months back. When driving it out of the dealer lot it had 130 miles. It has a instrument panel which gives the average mpg. Out of the dealer lot it showed 14 mpg. Now it has increased to 15.2 mpg at 790 miles and has stayed there for a long time. It is not giving the average of 21 mpg as advertised. I asked the service center about it and they said it will increase after 500 miles. I am having my doubts now. Does anyone have similar experience?

2009 Toyota Sienna Mileage Less Than Advertised.?

Those computers aren't that accurate. You may be getting better mileage than what it shows.
As for the mileage advertised, there is no guarantee you'll get that. There are a lot of factors that effect mileage and acceleration is probably the biggest.
Check your mileage by calculating it at fillups to see what you are really getting. If it's low, change your driving style. Take your time getting up to speed, try not to go over 55 if you aren't on an interstate highway, take your foot off the accelerator earlier as you approach places you have to stop. If it's still low, then complain to the dealer.

Like everyone else said, the mpg computers aren't always 100% accurate.
However I think the biggest reason is that your car is still very new. As cars wear in mpg improves. I had a 2005 Toyota Camry V6 that was advertised to average around 25 mpg. After about 50k miles the onboard computer said I averaged 22.3. That sounded about right since I tend to have a lead foot. Driving habits make a huge difference in varrying mpg performance.
After you've driven your Sienna 5 to 10k miles the engine should start to wear in and you should start to see your gas mileage improve.

first of all, calculate it the proper way, don't rely 100% on those numbers you see on the panel. fill up with gas until handle clicks, reset the trip meter. drive until the car is close to empty. fill up again until handle clicks. take the number of miles on your trip meter and divide by the number of gallons of gas you just put in your car.
having said that, yes it is common for a motor to not run as efficiently when it is new. Honestly, give it at least 5K miles before you start getting worried about it. It's also not uncommon for a new motor to burn oil, so keep an eye on it and top off as needed. Keep tires properly inflated. And lastly, it's very common for cars, in the real world, to not always get what the manufacturer claims. There's too many variables, your driving habits, weather, etc.. You might get 15mpg and I could take the same car and get 18. such is life.
