The 2005 Pontiac G6 has 4 recalls, the most serious involving the shift cable on automatic transmission models, which can fracture without warning and leave the driver unable to change gears, remove the key, or shift into Park.
Two recalls address brake lamp failures caused by separate electrical faults. Corrosion in the body control module's wiring connector can cause the brake lights to stay on when the driver's foot is off the pedal, or go dark entirely when the pedal is pressed, leaving following drivers with no accurate signal of what the car is doing. A related electrical fault can produce the same brake lamp misbehavior and also interfere with cruise control, anti-lock brakes, and stability control, reducing the car's ability to assist in emergency stops or maintain control on slippery roads. On vehicles equipped with electric power steering, the steering assist can cut out suddenly while driving, making the wheel noticeably heavier and requiring more physical effort to steer, particularly at low speeds or during a turn.
