Q: Fuel economy worse than advertised
I feel a little deceived, I have driven my 2012 GMC Terrain 30,000 miles now and I have never gotten fuel mileage as good as what was advertised. I drive gently and don’t speed. Even on long trips where the roads were straight and clear, less mpg than advertised. I like the car, but GMC had to have known their numbers were bogus. Is there a way to ask for a reimbursement for the spent fuel?
