GM is recalling 4,296 U.S.-market Chevy Sonic models—all assembled at the automaker’s Orion Township, Michigan plant, for a possible assembly issue that leaves the subcompact lacking either an inner or outer front disc brake pad.
According to General Motors, a rental Chevrolet Sonic was brought into a dealership in late November for brake noise, and found to be missing a pad during warranty service. While this sounds hard to believe, given that vehicles receive test-drives after assembly, those who brake lightly might not notice that anything is wrong right away. The issue would cause much longer stopping distances during emergency braking or harder brake application, however.
Through the effort, dealerships will inspect the front brakes (the Sonic had drum brakes in back), installing pads as necessary and installing a new caliper and rotor if a pad had been missing. GM is sending out notification letters for the recall beginning January 14, and the effort affects vehicles that were manufactured from June 2 through November 21, 2011.
