Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. 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?

2012 Chevrolet Sonic Owner Comments

problem #2

Sonic 4-cyl

The button to release the car out of gear, and once in park that releases the key came apart. It has been sticking for awhile then all of a sudden, something sharp started poking out of the bottom of the button, and it has cut my husband's hand. Now the button barely pushes in and the car is very hard to get out of park.

On or around December, 2014, the shift cover would not attach permanently. On or around March 10, 2014, the electrical access plug did not operate. On or around March 6, 2014, my mother was driving around 45mph, and we hit an elk. No airbags deployed.
