We're sorry to hear that some of you are not fully satisfied with your vehicles because of the fuel economy you are getting on them.
A few notes on fuel economy to pass along:
The EPA's fuel economy estimates are designed to allow consumers to comparison shop. Your fuel economy will almost certainly vary from EPA's fuel economy rating, which is based on a number of factors, such as weather, road conditions, driving and maintenance habits, and the use of air conditioning. For more information on how your fuel economy can vary, or tips to improve your fuel economy, please visit "Your MPG Will Still Vary" and "Gas Mileage Tips" on www.fueleconomy.gov
Terrain can also affect fuel economy - are your roads mostly flat or do you have to do hill/mountain driving?
I'm not sure about your odometer readings, but new vehicles will not obtain their optimal fuel economy until the engine has broken in. A typical engine will take 3 to 5 thousand miles to break in and during this time period a gradual increase in fuel economy can be expected.
If you are concerned and want to have your vehicle evaluated by your dealership, please keep Katie and I in mind as we're available to you. We can be contacted on the forum via private message or by email at [email protected]
(include your name and contact information, the last 8 digits of your VIN, and a brief summary of your concern).
