Chevy is recalling certain 2012 Sonics, manufactured between June 2, 2011,through November 21, 2011 because of brake system issues.
The recall was issued because the front inner or outer brake pad might be missing from the Sonic, which can cause a loss in brake system power and result in a collision. There is an estimated total of 4,296 Sonics which are affected by the recall. GM says that if you bring your Sonic into a local dealer the mechanics will inspect the front brakes, and if there is a pad missing it will be replaced by the company.
