In September 2015, Volkswagen Disclosed It Had Sold Hundreds of Thousands

In September 2015, Volkswagen disclosed it had sold hundreds of thousands of diesel cars in the U.S. with software specifically designed to evade government pollution tests. The company disclosed that the irregularities on diesel-emission readings extend to some 11 million vehicles globally. The company has admitted that it rigged diesel vehicles using a "defeat device" to pass lab tests, even though they emitted as much as 40 times the legal limit of pollutants on the road.
In November 2015, VW set a November 30 deadline for staff with knowledge about its diesel emissions test cheating to come forward. Workers who get in touch with internal investigators by then would be exempt from dismissal. VW said it would not sack workers for what they might reveal, but they might be transferred to other duties. "Employees covered by collective bargaining agreements who get in touch promptly, but no later than November 30, 2015... and... may rest assured that the company will waive consequences under labor law such as the termination of employment, and will not make any claim for damages," according to the letter sent to workers.
