Volkswagen admitted that up to 300,000 diesel cars worldwide may have been equipped with software that allowed the vehicles to cheat on emissions tests.
The company also said that more than 50,000 of its vehicles may have caused at least two other accidents in which at least one of the vehicles was involved.
VW announced the new findings in a blog post on Tuesday.
The German automaker said that the vehicles in question were used on 1.1 million diesel cars from 2009 through 2021.
The vehicles were sold from September 2009 through September 2021.
VW said it had determined that more diesel vehicles were affected than previously reported.
Volkswagen admitted to using software to cheat in the 2017 and 2018 models of its Passat and Passat XL diesel cars.
It also said it found that up a third of the diesel vehicles sold in the United States had been equipped to cheat emissions tests for years.
VW will pay a $15 million fine and $13 million in penalties.
The US Department of Justice said in a statement that the company agreed to pay $2.4 billion for its emissions scandal and would pay $1.2 billion in restitution.
The Justice Department also said the company had to create and implement new controls that “will prevent future cheating.”
