GM pickup owners sue, alleging emissions cheating

The suit, filed in federal court in Detroit, is on behalf of more than 705,000 people who bought or leased Chevy "Duramax" Silverado and Sierra trucks between 2011 and 2016.

Consumers are suing General Motors for allegedly rigging the emissions controls in Duramax diesel trucks in order to pass emissions tests, while in real-world conditions the trucks emit 2 to 5 times the legal limits of deadly NOx pollutants, according to Hagens Berman.

GM said the suit has no merit and will vigorously defend itself.

General Motors on Thursday denied allegations made in a lawsuit that the company's full-size diesel pickup trucks cheat on emissions tests.

If the claims in the lawsuit against GM are proven true, the company will nearly certainly face major sanctions from US - and possibly global - regulators.

There's not yet any accusation from regulators or any federal investigation announced by the U.S. Environmental Protection Agency (EPA) or the California Air Resources Board (CARB).

For Aaron Cockerill, it was a shock to the system and a not-so-subtle reminder of how precarious things can be out on the links. I don't see where that's a bad thing, politics aside. "Play with what you have and that's what I did".

A lawsuit on behalf of 705,000 GM Silverado and Sierra diesel truck owners alleges the vehicles have technology on them created to beat emissions tests.

In the case of Fiat Chrysler Automobiles, drivers filed a class action alleging VW-like cheating on diesel emissions tests and shortly after, US prosecutors and regulators were investigating as well.

Berman says after the Volkswagen diesel emissions scandal broke, he didn't believe it was limited to that one automaker.

Auto parts supplier Robert Bosch GmbH was named as a co-defendant in the VW case, and was also named in the GM suit as "an active and knowing participant in the scheme to evade" emissions standards.

The lawsuit, which seeks class-action status, underscores questions about the credibility of clean-diesel technology.

GM shares fell as much as 2.7 percent after the lawsuit was filed on Thursday, but gained some of that loss back in afternoon trading. Based on its testing of emissions control systems, the firm is also leading litigation against Chevrolet, Fiat-Chrysler and Mercedes for illegal use of emissions-cheating software.
