Volkswagen Diesel Recall Lawsuits

GMC and Chevy Diesel Emissions Cheating Lawsuits

General Motors is facing lawsuits over allegations of emissions cheating on its diesel trucks. Consumers who own or lease one of the Chevrolet Silverado or GMC Sierra diesel pickup trucks with Duramax engines involved in GM’s emissions cheating may qualify to file a lawsuit against the automaker.

According to the lawsuit, GM installed three emissions defeat devices on more than 700,000 diesel trucks equipped with Duramax diesel engines, including the following models:

  • Chevy Silverado 2500 HD Duramax diesel, 2011-2016
  • Chevy Silverado 3500 HD Duramax diesel, 2011-2016
  • GMC Sierra 2500HD Duramax diesel, 2011-2016
  • GMC Sierra 3500 HD Duramax diesel, 2011-2016

The defeat devices installed on these models were designed to conceal the high emissions levels of the affected trucks from drivers and regulators. Emissions testing performed on the affected GMC Sierra and Chevy Silverado models found that these trucks release nitrogen oxide (NOx) emissions that are far higher than those advertised by the company or permitted under EPA regulations.

Drivers who own or lease one of the affected Silverado and Sierra Duramax diesel truck models paid about $5,000 more for these vehicles than comparable gasoline-powered models. The lawsuits allege that Sierra and Silverado Duramax drivers were wrongfully overcharged for environmental and performance benefits that were advertised by the company, but which these vehicles failed to deliver as a result of GM’s fraudulent conduct.

Allegations of Diesel Emissions Cheating Against GM

GM allegedly installed the defeat devices on the affected Silverado and Sierra Duramax truck models because of design modifications intended to boost the performance of these vehicles. When GM built the affected GMC Sierra and Chevy Silverado trucks, it reversed the traditional order of the Selective Catalytic Reduction (SCR) and Diesel Particulate Filter (DPF) systems in these models.

By placing the SCR in front of the DPF, GM was able to significantly boost the performance of these vehicles. However, in order to bring the vehicles into compliance with federal emissions laws, would need to install exhaust treatment systems in the truck which would negate the performance gains on these models.

Rather than doing so, GM instead decided to install three emissions defeat devices on the affected Chevy Silverado and GMC Sierra trucks. The first emissions defeat device is designed to turn off the vehicles’ emissions control systems when they are being operated above 86 degrees Fahrenheit, when emissions can be nearly six times the EPA emissions limit. A second defeat device turns off the emissions control systems when the vehicles are operated below 68 degrees Fahrenheit, when emissions can rise to more than twice the EPA limit.

The third defeat device is designed to reduce the trucks’ emissions controls after 200-500 seconds of steady speed operation, increasing the emissions levels to about 4.5 times the EPA maximum. According to the class action lawsuit filed against GM, the affected GMC Sierra and Chevy Silverado models operate about 65-70% of the time with the defeat devices engaged.

Emissions Cheating Allegations Against Bosch

GM is the latest auto manufacturer to face allegations of emissions cheating in the last two years. In 2015, Volkswagen admitted that it installed a defeat device on 11 million “TDI Clean Diesel” models sold in the US and Europe. The company later agreed to a $10 billion settlement in the litigation over the Dieselgate scandal. Audi, Chrysler, and Mercedes have also faced lawsuits in recent years over allegations of emissions cheating.

Many of the vehicles involved in these lawsuits – including the Silverado and Sierra Duramax trucks – employed electronic diesel control (EDC) systems manufactured by auto parts maker Bosch. According to the lawsuit filed against GM, Bosch designed and produced the defeat devices that allowed GM to carry out its emissions cheating on the affected Silverado and Sierra diesel models.
