Chevrolet Sonic driver's seat back may be weakly welded medium
On some 2018 Chevrolet Sonic cars, a welded joint in the frame of the driver's seat back was not done properly, which leaves that seat back weaker than it should be. If someone hits your car from behind, the driver's seat back could break instead of holding you in place, and you could be hurt more badly in the crash. A dealer will install a whole new driver's seat back for free.
