General Motors/ Chevrolet Chevrolet Camaro Misleading and inaccurate fuel economy Detroit, Michigan

The 2011 Chevrolet Camaro advertised fuel economy of 18 City and 29 Highway. I purchased the Camaro in March of 2011. Within 400 miles I realized the vehicle was getting significantly lower MPG. The onboard computer indicated that that vehicle was getting 13.1 miles per gallon. I did a manual calculation and came up with the same number. I brought it into the dealer and was told it would take 8,000 to 10,000 miles before I got the advertised MPG. I kept a record both by the onboard computer and a manual calculation and the fuel economy continued to drop to 12.883 miles per gallon. I took it to the dealer again and was told that the vehicle checked out perfectly.

I then contacted GM and the Better Business Bureau and after a four month arbitration was told that mileage varies and that it was out of the Better Business Bureaus jurisdiction. I provided four months of gasoline receipts, manual calculation and dashboard photos showing the onboard computers readings and still GM denies that there is a significant difference between what is advertised and what was delivered. I also provided a copy of an email from the dealer representative that I purchased the vehicle from. In the email, she claims that this happened with a Chevy Equinox and General Motors purchased the vehicle back. However, they still deny an issue with the Camaro even after they were given all of the above proof.

Beware. GM does not stand behind the claims they make of the vehicles they manufacture.
