phoned 4 dealers and all say never heard of this problem and nothing they will do about it until you reach 20,000km, and that will take me a good 4 to 5 years. so it is a very bad fuel mileage at 13 miles to the gallon when it is rated at 32 miles to the gallon. Purchased brand new because of the mileage that was posted and I have decided after the service I am receiving from the Chevrolet dealers it will definitely be the very last Chevy I every purchases.

Update from Aug 21, 2013: I finally got a dealer to do a fuel consumption test, and after they did the first test which got a result of 11.7 miles to the gallon. They couldn't believe the results so they did a second test and then it was 12 miles to the gallon. Now we have to wait on GM Canada to decide what they will do if they will do anything which can take two weeks to months to decide what to do and if they can do anything.

Update from Sep 9, 2013: 3 weeks still waiting on gm Canada what to do

Update from Dec 3, 2013: NOT DOING ANY THING WITH FUEL PROPLEM.FILED FOR BBB.STILL DID NOT A THING
