For enhanced safety, the front and second-row seat shoulder belts of the Kia Sorento have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Acadia doesn’t offer pretensioners for its second-row seat belts.
Both the Sorento and Acadia have child safety locks to prevent children from opening the rear doors. The Sorento S/EX/SX/Prestige/X-Line has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Acadia’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
Over 200 people are killed each year when backed over by motor vehicles. The Sorento Prestige has standard Parking Collision Avoidance-Rear that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Acadia doesn’t offer backup collision prevention brakes.
Both the Sorento and Acadia have rear cross-traffic warning, but the Sorento has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Acadia’s Rear Cross Traffic Alert doesn’t automatically brake.
The Sorento’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Acadia doesn’t offer a driver alert monitor.
Both the Sorento and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.
