Lawsuit Alleges GM Cheated On Diesel Pickup Emissions

Comparatively, Volkswagen admitted to installing a device to skirt emissions tests on roughly 550,000 vehicles in the US, which sparked the so-called Dieselgate scandal in 2015 that has ever since increased attention on diesel emissions across the world.

About 18 months ago, Volkswagen was hit with allegations of using a device in its diesel-powered cars that could skate around diesel emissions regulations. But the suit says plaintiffs conducted a test of GM's trucks and found they emitted two to almost six times the legal limit.

GM spokesman Dan Flores called the claims "baseless", and said the trucks comply with U.S. Environmental Protection Agency emissions standards and California's own tough standards.

Customers have now filed a class-action lawsuit accusing the company of using "VW-like defeat devices" in over 700,000 diesel trucks from 2011 to 2016. The other reduces the level of emissions controls when the trucks are running continuously for 200 to 500 seconds. Instead, GM used three defeat devices that turn down emissions controls when the vehicle is not being tested, the lawsuit alleges. Bosch says it is cooperating with government investigations into emissions cases and "defending its interests" in lawsuits.

GM erased gains in early trading and fell as much as 3.9 percent after the lawsuit was filed. The suit targets more than 705,000 vehicles now estimated to be on the road, with model years between 2011 and 2016.

The lawsuit demands a jury trial and seeks punitive damages, restitution, and recovery of the purchase price of the trucks or the decrease in their values because of the devices.

"GM claimed its engineers had accomplished a remarkable reduction of diesel emissions", attorney Steve Berman, a managing partner at Hagens Berman, said in the complaint. Hagens Berman has also sued Fiat Chrysler.
