The QX70 is pretty much mechanically identical to the previous FX37, so its safety package hasn't changed much versus that model. There's a long list of standard and available safety equipment here, and existing safety ratings are positive.
Bluetooth and a rearview camera system are standard on the QX70; and because of obscured visibility from the curvy sheetmetal it does especially need that camera. There's also Infiniti's AroundView camera system, which mounts fisheye lenses on the underside of its outside mirrors and on the nose and tail of the vehicle. The results are stitched together and displayed on the dash's LCD screen for a 360-degree scan of the surroundings. As a standard feature on the QX70 3.7 and optional on the QX70 5.0, this system is useful for parking in narrow garage and parking lot spaces.
Other safety options are bundled in packages. There's Lane Departure Prevention follows lane markings on the road, notifies the driver, and can even apply the brakes lightly, while an advanced cruise control system can bring the FX to a complete stop if traffic slows.
Because the QX70 is a relatively low-volume model, it's likely that the National Highway Traffic Safety Administration (NHTSA) won't test this crossover. But the insurance industry-funded Insurance Institute for Highway Safety (IIHS) did test the FX and found it "good" rating for front and rear impacts. It wasn't tested for side impacts or roof strength, however it achieves an 'advanced' rating for frontal crash prevention.
