A law firm is suing General Motors, claiming the automaker's diesel Cruze sedans cheat on emissions tests, just like Volkswagen's diesels.
Volkswagen is in big trouble for deliberately installing software that turns off emissions controls during normal driving, and on during fuel economy testing.
The U.S. Environmental Protection Agency sued Volkswagen over the deceit. The Associated Press reports an announcement of a settlement will be made early next week.
Now, the Hagens Berman law firm, using a portable emissions testing system, claims it's caught GM doing the same thing.
The lawsuit says emissions of nitrogen oxides from Chevy Cruze diesel turbos were up to eight times the allowable standard, and seeks damages for customers who believed they were buying a "clean" diesel car.
A statement from GM says the claims are baseless and the company believes the Cruze turbo diesel engines comply with all U.S. emissions regulations.
