GM is accused in lawsuit of cheating on diesel truck emissions
General Motors Co (N:GM) was accused in a lawsuit on Thursday of rigging hundreds of thousands of diesel trucks with devices similar to those used by Volkswagen AG (DE:VOWG_p), to ensure they pass emissions tests.
The proposed class-action lawsuit covers people who own or lease more than 705,000 Chevrolet Silverado and GMC Sierra pickups fitted with “Duramax” engines from the 2011 to 2016 model years.
It said GM used at least three “defeat devices” to ensure that the trucks met federal and state emission standards, even if they generated more pollution in real-world driving. The complaint was filed in the federal court in Detroit.
“These claims are baseless and we will vigorously defend ourselves,” GM spokesman Dan Flores said.
He added that the trucks comply with U.S. Environmental Protection Agency emissions standards and California’s own tough emissions standards.
The lawsuit alleges violations of racketeering and consumer protection laws, and seeks remedies including possible refunds, restitution for lost resale value, and punitive damages.
It adds to legal problems for Detroit-based GM, which has already paid about $2.5 billion in penalties and settlements over faulty ignition switches linked to 124 deaths.
GM joins VW, which has admitted to cheating, and at least four other automakers whose diesel emissions have been scrutinized by regulators or consumers.
