For enhanced safety, the front and second-row seat shoulder belts of the Hyundai Santa Fe 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 Cadillac XT4 doesn’t offer pretensioners for its rear seat belts.
Both the Santa Fe and XT4 have child safety locks to prevent children from opening the rear doors. The Santa Fe 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 XT4’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.
The Santa Fe’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 XT4 doesn’t offer a driver alert monitor.
Both the Santa Fe and the XT4 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, 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.
The Hyundai Santa Fe weighs 461 to 793 pounds more than the Cadillac XT4. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Hyundai Santa Fe achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The XT4 has not yet been fully evaluated by the IIHS for 2024.
