In the last two months, Volkswagen has admitted that over 11 million vehicles have a "defeat device" installed. This software was installed on as many as 500,000 cars in the U.S. and is used to trick regulators into believing the car is compliant with "clean diesel" regulations, even though it isn't. Some cars are actually emitting up to 9 times the acceptable limit.

This is just the beginning as certain Audi and Porsche vehicles have also been affected. As of November 4, 2015, there is a stop-sale order for 3-liter, 6-cylinder diesel versions of the 2015-16 Audi A6, A7, A8 and Q5, as well as certified pre-owned models. Because of the stop-sale for Audi, the sales of 2015-16 Volkswagen Touareg and the 2014-16 Porsche Cayenne have also been halted.

Volkswagen has also released a statement indicating that over 800,000 cars have had "irregularities" with emissions testing. While most affected engines are diesel, these "irregularities" have also been found in the 1.4-liter gasoline engine that has a cylinder deactivation feature.

These car companies have violated not only their consumers' trust, but also the Missouri Merchandising Practices Act. Many of you have purchased cars under false pretenses and most likely paid an undeserved premium for them. Their apology letters are not enough to make up for their wrongdoings.

How to tell if you're affected:

Check the model of your car's engine to see if you have an affected vehicle. Cars with a Volkswagen's EA 189 diesel engine or 1.4-liter gasoline engine produced between 2009 -2015 could be eligible. Check your service book or VC5 to confirm your engine model number or call Volkswagen customer service.
