The 2003 Infiniti G35 has 5 recalls, the most serious being a fuel pump hose connection that can work loose while driving or at startup, cutting off fuel flow and stalling the engine without warning.
A malfunctioning brake light switch affects both sedan and coupe models: when the brakes are applied, the brake lights may fail to illuminate, leaving drivers behind with no indication the car is slowing. That kind of invisible stop significantly raises the risk of a rear-end collision. On the lighting side, certain sedan models were assembled without the tamperproof caps that lock the headlamps against horizontal adjustment. Without those caps, the headlamp aim can shift over time, potentially pointing light away from the road ahead or into oncoming traffic rather than holding the angle set at the factory.
