Safety features include standard electronic stability control, anti-lock brakes with Brake Assist, front side airbags, and side-curtain airbags that cover both rows of seating. The G37's poise, good steering, and excellent dynamics might also be considered an accident-avoidance safety asset.
Adaptive Front Lighting and the Intelligent Cruise Control are optional (provided you move up to the Journey model) and with them you get a Preview Braking safety feature.
The Insurance Institute for Highway Safety (IIHS) has given the G37 top 'good' scores for frontal and side impact, but in the roof-strength test it achieves a score of just 'acceptable.' Marginal scores in the seat-based rear-impact test (as of 2012) are also concerning.
