2006 Sienna Owner Reviews (1)
Our Sienna XLE is approaching 40,000 miles. The majority of the miles are highway, which should evidence better gas mileage. However, we notice that the mpg is 19-20 regardless of where we are driving. This is very poor gas mileage, which leads me to believe that estimates are based upon faulty input. Do the manufacturers really place the autos on elevated equipment similar to EPA checking stations, to achieve the higher numbers. If so, the quoted statistics are bous and should be forced to cease printing incorrect info.
