The middle row seatbelts optional on the Expedition inflate when a collision is detected, helping to spread crash forces over a much larger area of the body and limiting head and neck movement. This can help prevent spinal and internal injuries. The Sequoia doesn’t offer inflatable seatbelts.
Full-time four-wheel drive is optional on the Expedition. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Sequoia.
The Expedition’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 Sequoia doesn’t offer a driver alert monitor.
Both the Expedition and the Sequoia have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, 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 and available around view monitors.
