Serious issues with this car. Shifting kicks and makes the whole car lurch when it changes gears, makes the shifter freeze and I am unable to go into any gear at all leaving me stuck numerous times. Sometimes I think the whole drivetrain is going to fall out. I have contacted Chevy about this issue and as they couldn't reproduce the problem due to warmer weather they were unable to do anything about it. This also makes the automatic locks stop working when it does finally go into gear.
