Poor MPG
2012 Chevrolet Sonic
This problem may be covered under warranty. Ask your Chevrolet dealer.
CarComplaints.com 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?

Bought my car to save on fuel..I have a truck also which gets 14mpg.I bought the sonic in hopes to save on fuel. With a promise of close to 49mpg s. 4 months later I got maybe 21mpg,then it slowly went up to 27mpg..then stopped..All highway!!The gas tank is so small u have to fill up a lot more.The insulation of the tank must be crap. I CAN PARK ON A FULL TANK,when I get back in I lose 1 to 2 bars just from the heat or evaporation. Not happy!!
