This Cruze has been in the shop many times. The last time it was for an emission fault and when it came out of the shop from that, it started surging. I am really disappointed in the car. I am the original owner and I have had nothing but problems starting at 7K on this car. Every 7k miles it has to go to the shop to have the sensors replaced or some program updates. There has not been any cost to me except time as it has been under warranty, however that is about to change with the number of miles I have on it now. I will never buy another Chevrolet.
