    upon acceleration from a red light or stop sign ,if i encounter rough roads or pot holes the vehicle will react like i was on ice, the rpms would jump from normal rpms to 2500 , and 3000 and would have let off the gas to get things back to normal acceleration,mostly on cornering and once in very short while when i start the car it just quits and will have to restart.other than that i love it.i owned an outlander for 11 years and it never let me down i would have bought another but they decided to get rid of that very nice hatch back, tail gate option which was the perfect combo for me. owned mazda pick up loved it,owned a dodge pickup piece of shit so lets see if this so far so good car has to offer
