Ford is lowering its fuel economy estimates for six models, including the Fiesta subcompact and hybrid and plug-in hybrid versions of the Fusion sedan.
The mileage on most labels will fall between one and five miles per gallon. The biggest change is for the Lincoln MKZ hybrid, whose combined city and highway fuel economy has been reduced by 7 mpg to 38 mpg.
Also affected is the C-Max hybrid and C-Max Energi. Ford restated the C-Max's mileage once before, in the fall. But the company says this is a separate issue.
Ford will compensate 215,000 buyers with payments of between $125 and $1,050. Most of those customers are in the U.S.; around 15,000 are from Canada and elsewhere.
Ford says it found the errors as part of an internal audit.
