Over 200 people are killed each year when backed over by motor vehicles. The Sonata Limited has standard Reverse Collision-Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Impala doesn’t offer backup collision prevention brakes.

The Sonata Limited has a standard Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The Impala only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the Sonata and the Impala have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front-wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.
