BRAND NEW 2015 GMC Terrain, 245 miles, its listed as 22 city MPG. I live in LA, very flat and regular traffic and driving conditions. We don't use the AC and we get 12MPG......DREADFUL!! and unacceptable.....Dealer said it needs time to break in at 5000K.......They gave me a loaner while they ran tests, a GMC Arcadia, three rows seats bigger 6 cylinder engine and it only had 125 miles on it so it was NOT broke in.......Well I have driven that for two days and I am getting 18MPG and this car is listed at getting 17mpg!!!
