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

Sonic 4-cyl

As I was making a left turn in an intersection at 5:30am my rear glass window burst and all the glass shattered leaving glass on the four sides only. Inexplicable how it happened, my first reaction was too look back and see if anybody had hit us, but when I looked through the rear/side mirrors there was no cars behind us or near us. The same morning I called the dealership and they towed my vehicle to the shop for a transmission recall, per the dealer they would not cover it under the warranty due to General Motors had no other vehicles reporting the same incident. I feel it should be looked at because I'm sure many 2012 Chevy Sonics have it as a defect. With so many recalls I wouldn't doubt that the windows are being recalled as well.
