The plaintiffs are accusing Ford of rigging the engines to beat emissions tests which, sadly, is a story we've heard over and over as automakers like Volkswagen and Fiat Chrysler battled their own allegations, in the past two years, of similar practices.
This time the Dieselgate crosshairs are leveled at Ford, courtesy of a lawsuit filed yesterday from disgruntled F-250 and F-350 Super Duty owners who allege their trucks emit far more nasty bits into the air than advertised.
According to a Bloomberg report, a Ford spokesperson said in a written statement, "All Ford vehicles, including those with diesel engines, comply with all U.S. EPA and CARB emissions regulations".
Another lawsuit over diesel emissions was filed Wednesday in federal court in Detroit. A defeat device is software created to fool emissions tests by allowing a vehicle to boost its performance, but pollute substantially more in real-world driving.
Meanwhile, Ford and Bosch have denied the allegations.
Bosch is also accused of developing software that enabled Ford to adjust fuel levels, exhaust gas re-circulation, air pressure and urea injection rates while being tested for emissions by regulators including the Environmental Protection Agency and California Air Resources Board.
On Wednesday, Bosch said it took "very seriously" allegations of diesel software manipulation by Ford Motor Co raised by a USA law firm which named the components maker as a defendant in a lawsuit.
Bosch noted the "sensitive legal nature of these matters" in its response to a request for comment. It is a well-known fact that these allegations remain the subject of investigations and civil litigation involving Bosch. Bosch is cooperating with the continuing investigations in various jurisdictions, and is defending its interests in the litigation.
Volkswagen has struggled to draw a line under its diesel emissions scandal, which broke in the United States in 2015 and has cost the German company as much as $30 billion. The auto show's media preview starts Sunday.
