General Motors is expanding a recall it issued last year as it discovered more vehicles affected by the problem. The recall, which covers a problem that could cause the wheels to lock up, now impacts more than a half-million vehicles from Chevrolet and Cadillac.

General Motors will recall more than 90,000 Cadillac and Chevrolet Camaro models due to transmission control valve issues which could cause lock tires and lead to a crash.
