Notes: The 2012 Chevrolet Sonic is fairly new & is already showing an early trend of transmission problems.

Owners report hesitation when shifting & grinding/hard shifting into gears. Some dealers are calling the condition "normal". Another owner reported his dealership replaced the transmission under warranty, but the new transmission had the same exact grinding problem. Design defect?
