GM Lawsuit: Reportedly Sold Non-U.S Fuel Compatible Diesel Trucks

Lawsuits. It’s a word that usually never ends well and for a company as big as General Motors, you know the numbers will be high. GM has been hit with a lawsuit recently for allegedly selling GMC and Chevrolet diesel trucks that are not compatible with American diesel fuel. That oh-so-loved 6.6-Liter Duramax engines in the 2011-2016 range apparently weren’t designed for our fuel.

In a Detroit-based federal court, the lawsuit was presented where details were provided on the faulty fuel systems where hundreds of thousands of trucks are affected. Apparently, the high-pressure injection pumps are designed by Bosch, a German auto supplier, and pumps metal shavings into the fuel injection system and damaged said systems and even the engines.

What they are explaining is American diesel fuel is thinner than European diesel fuel and doesn’t obtain as much lubricity. The metal shavings are a result of the air pockets forming internally and causing metal on metal contact.

“The pump secretly deposits metal shavings and debris throughout the fuel injection system and the engine until it suddenly and catastrophically fails without warning,” the lawsuit claims. “Such catastrophic failure often causes the vehicle to shut off while in motion and renders it unable to be restarted because the vehicle’s fuel injection system and engine component parts have been completely contaminated and destroyed.”

“GM promised consumers the continued reliability of their diesel engines, but with increased fuel efficiency and power at greater fuel efficiency.”

The lawsuit involves:

  • 2011–2016 2500HD Silverado 6.6L V8 Duramax diesel trucks with LML engines
  • 2011–2016 3500HD Silverado 6.6L V8 Duramax diesel trucks with LML engines
  • 2011–2016 2500HD Sierra 6.6L V8 Duramax diesel trucks with LML engines
  • 2011–2016 3500HD Sierra 6.6L V8 Duramax diesel trucks with LML engines
  • 2010–2011 Chevrolet Express vans with Duramax LGH engines
  • 2010–2011 GMC Savana vans with Duramax LGH engines
  • 2010–2011 GMC Sierra trucks with RPO ZW9 (chassis cabs or trucks with pickup box deleted) with Duramax LGH engines
  • 2011–2012 Chevrolet 2500HD Silverado 6.6L V8 Duramax diesel trucks with LGH engines
  • 2011–2012 Chevrolet 3500HD Silverado 6.6L V8 Duramax diesel trucks with LGH engines
  • 2011–2012 Chevrolet 2500HD Sierra 6.6L V8 Duramax diesel trucks with LGH engines
  • 2011–2012 Chevrolet 3500HD Sierra 6.6L V8 Duramax diesel trucks with LGH engines.

It isn’t anything new to be under fire for the performance of diesel vehicles. As you may know, Volkswagon has already been involved with their own issues lately with emissions testing. In fact, after it was all said and done, Volkswagon was forced to pay $2.8 billion in criminal fines in relation to evade U.S emission standards.

Who knows what is next for GM as they undergo this investigation. Do you own a truck in this year range? Have you had similar issues? Let us know in the comments below. Stay tuned to Diesel Army as we will keep you up to date with the latest news on the subject.
