I am never buying a Volkswagen after the Volkswagen Emissions Scandal in 2015.
Betcha that some Energy Star appliances can detect when they are being run through a test cycle.
And it's not like this was the first time: https://en.wikipedia.org/wiki/Defeat_device
It's really quite weird that it has become associated so closely with Volkswagen.
Not enough to matter, even if they had no emissions controls at all.
