There are five active recalls for the 2007 Chevrolet Cobalt as of March 2015 that involve the car's ignition, air bag, steering and fuel pump. Not all 2007 Cobalts are affected by all of these recalls, however.
The most infamous and potentially dangerous item involved in the recalls for the 2007 Chevrolet Cobalt is the car's ignition switch, which has been confirmed as the cause of at least 67 deaths due to accidents according to investigators working for General Motors. The specific defect allows the key to slip in the ignition switch, potentially resulting in the car shutting off while at speed. The airbag system may also be disabled if this occurs, making any resultant crash much more likely to be lethal. GM is replacing ignitions to remedy this defect, as well as a second ignition defect that can allow a parked Cobalt to roll away and cause an accident.
Recalls for the 2007 Chevrolet Cobalt's air bag system are related to the defect reported in the ignition recall, but this recall affects additional vehicles that were not initially recalled. The recalls for the Cobalt's fuel pump involve leaking pumps on cars sold in Western states that must be replaced, while the steering recall is intended to replace defective power steering motors that can cause the loss of power steering capabilities at any time while driving.
