Ford F-250 and F-350 Super Duty Diesel Vehicles

In January and April 2018, two class-action lawsuits were filed against Ford Motor Company for allegedly deceptively advertising its F-250 and F-350 Super Duty vehicles as being the “Cleanest Super Duty Diesel Ever” with reduced nitrogen oxide (NOx) emissions when, according to the complaint, the vehicles have a device that turns down the emission controls when they are not being tested resulting in vehicles that emit more pollution during normal driving conditions than during testing. According to the complaints, the pollution emitted from the vehicles also exceeds federal- and state-imposed limits. Plaintiffs also allege that Ford’s marketing promises that the vehicles have “best-in-class fuel economy” and “best-in-class towing” without disclosing that the fuel economy could only be achieved when the emission controls were reduced and that the towing capabilities came with high NOx emissions.
