the engine is in the grand cherokee too... and fca is using both ram and jeep as the two images they want to be recognized by. so i'd say it's valid.
all of these articles i have read have really been tricky. they talk about the epa's issue and that they found unreported emissions controls... but then refer to "cheat" devices with the lawsuit. it is the same things the two groups have issues with. a cheat device is setting up the car to recognize it is being tested, and alter the way it works in order to pass emissions. these are not cheat devices that the 3L has...
there is nothing that "cheated", just that at high speeds and heavy use applications, the engines computer would opt for more power rather than prioritize emissions control. if i was towing a trailer through the mountains, and had to floor it... i would really like to get up the hill, even if it caused a bit more pollution.
so dumb.
