DETROIT, MI (AP)-- A person familiar with the matter says Ford will reduce the gas mileage estimates on the window stickers of its C-Max hybrid.
The move comes after an investigation by the Environmental Protection Agency, which enforces mileage estimates.
Customers have complained that the C-Max doesn't get the advertised 47 miles per gallon in combined city and highway driving.
The person says the mileage estimate will be cut by nearly 9 percent to 43 mpg.
They said that Ford followed EPA methods to calculate the mileage, but in this case that resulted in the mpg numbers being overstated.
The person didn't want to be identified because the change hasn't been revealed publicly.
A Ford spokesman would not comment.
