What are your sources? Are you referring to the diesel VW emissions cheating debacle? If so, the Cruze is not involved (yet).

Anybody know if there is any truth behind the dieasels being declared lemons?
The word's use to describe a highly flawed item predates its use in describing cars and can be traced back to the beginning of the 20th century as a British and American slang.[SUP][1][/SUP]
Its first attribution to mean a problematic car was in a Volkswagen advertisement created by Julian Koenig and Helmut Krone as part of an advertisement campaign managed by William Bernbach, all advertising executives with the firm Doyle Dane Bernbach in 1960, which was a follow-up to their Think Small advertising campaign for VW.[SUP][2][/SUP][SUP][3]

EPA has dual standards, did I say dual? More like multiple standards, commercial vehicles like diesel semi's that would line the interstates for hundreds of miles, bumper to bumper were the last on the list puffing out black smoke loaded with sulfur.

Course then, dealing with large corporations that have the best attorneys money can buy. Its so much easier to pick on the little guy popping along on a little tiny less than 2 L engine, and this is what they do.

Hmmm, come to think of it, the IRS is the same way.

Unfortunately, the greater the efficiency of an engine, the greater the production of NOx's or more precise, N2O, also called ozone, but in the lower atmosphere and not nearly as bad as the emissions that can affect our ionospheric ozone layer that protects against harmful UV radiation from our very own sun.

N2O emissions do have a positive side since both man made and our earth emitting tons of methane gas. N2O will break this down.

N2O is an irritant for use humans, and particularly bad in our way over congested cities where people like to pile up on top of each other. But really major sources of its production is our space program, military, and airlines, EPA tends to ignore this. What combines oxygen with nitrogen is heat. But the more the heat, the more efficient our machines are.

So the price we pay is poorer fuel economy and using a lot more HC's to get us there.

Can really go around in circles with the subject, but still a lot easier to pick on the little guys.

I have 143,000 miles on my Cruze diesel and it is FAR from a lemon. In fact, it's been a very reliable and awesome car. not sure what you are asking??

The way you can get better fuel economy with direct fuel injection like in the diesel is to lean out the mixture when running at constant highway speed. But apparently not caught by standard exhaust pipe emission testing, because the engine is always changing speed. Lean burning runs a lot hotter that generates more NOx's. In the case of VW 40 times as much.

Never would be caught in Wisconsin, got away from real emission testing and just check to see if your check engine light is off. With a scanner, can also check for historical codes, but they can get rid of by starting and stopping the engine so many times depending on the code.
