Over the past year, we have started watching legislation and the courts to see what is coming down the pipeline. In that time, we have actually seen a number of states taking positions against modifications and against the rebellious tendencies that many of us diesel owners have.

Recently, we started seeing multiple news outlets post stories about a new lawsuit against GM. The lawsuit will probably not pan out to be anything, but it is something to at least be aware of. According to Carcomplaints.com, Kenneth Dzieciolowski and Anthony Acedo are suing DMAX LTD. over what amounts to false advertising.

Their claim is that GM advertises the new Duramax engines to offer better fuel economy and increased reliability, but that isn’t the case. They are claiming the regeneration cycles cause a decrease in fuel economy and due to the increased complexity of the system, the cost of ownership is more.

Anyone who has owned a newer truck had seen this first hand. With the new emissions requirements, there are lots of additional components and processes the manufacturers have to adhere to in order to sell diesel engines.

Now again, we expect this lawsuit to go nowhere, but if we play the “what if” game, this could be one of those lawsuits that changes how things are done. The court case is in the U.S. District Court Central District of California Western Division and if the plaintiffs win, they are seeing a re-design and retrofit of all vehicles with a Duramax, according to Car Complaints.

There is a new Duramax already in the works and rumor has it being introduced as a 2017. Even if the plaintiffs win, Dmax will surly appeal and this will be a long drawn out process. But it will be interesting to see where this goes. The Duramax engine was introduced in 2001 as an LB7. The particular engine in question is a LML (2011-present).
