EPA administrator announces power-loss ‘fix’ for diesel exhaust fluid systems 

The EPA is changing how diesel exhaust fluid systems work, aiming to prevent sudden breakdowns that have long frustrated farmers, truckers, and construction crews. Announced by Administrator Lee Zeldin at the Iowa State Fair, the new guidance will require 2027-model trucks to avoid abrupt power losses when DEF runs out, and offers software fixes for existing vehicles. Officials say the shift could save family farms hundreds of millions annually, easing a rule critics argue has stalled equipment at the worst times while still meeting emissions goals.
