No major ones to date. The minor issue has been the maintenance free battery that came with the car. It tends to die on us (twice) very suddenly.
1.4L is slightly underpowered, but we wanted a manual car and it was only offered as a 1.4.
When on the road it handles very well. We wished the insulation was better as the road noise does sometimes intrude a little too much.
Consumption is comparable (city+highway) is about 14-15km/L which is quite good considering the car is heavy. We don't try to be the first off the line, which helps the consumption.
With a 1.4 liter, you are never going to be first off the line whether you try to or not.
Unless the other vehicle is a mule cart.
Shouldn't this be an OPEL rather than a Chevrolet?
