The contact owns a 2011 Chevrolet Malibu. The contact stated that the vehicle hesitated while attempting to accelerate. The contact mentioned that there was a 3-4 second delay when the accelerator pedal was engaged. The vehicle was taken to the dealer who explained that the manufacturer changed the way the system reacts in the vehicle, as a result the signal from the accelerator pedal goes through the computer first and then the engine which causes the delay. The VIN was not available. The failure mileage and current mileages were 4,800.

I bought my 2011 Malibu ltz in April 2011. Since I bought it I have noticed, consistently, the car revs extremely high when shifting between gears while accelerating. It often times struggles to shift between 2nd and 3rd and 4th gears. The car is also rated to get up to 33 mpg highway, average of 25. I drive about 90% highway and backroads and am only getting an average of 23.3 mpg, which is the city rating. This car has a 6 speed auto and was supposed to do better on gas than the last few models, but my 2009 Malibu with a 4 speed auto did better than this car does. Initially I figured I was doing bad on gas because I tend to be a leadfoot driver, so I made significant strides to reduce my overall speed and quick accelerations. After about 4 months now of driving slower and safer I have not seen any change in the mpg. I am about to make an appointment to get the fuel system checked out. I also have the automatic starter in my car and it has died at 25,000 miles. I don't know if this is average battery life span for it or if it is an issue, so I will be getting it checked out too.
