For enhanced safety, the front seat shoulder belts of the Mazda CX-5 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The GMC Terrain doesn’t offer height-adjustable seat belts.
The CX-5 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Terrain doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The CX-5 Turbo Signature has standard Smart Brake Support-Rear that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Terrain doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-5. But it costs extra on the Terrain.
The CX-5 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Terrain’s blind spot costs extra.
To help make backing out of a parking space safer, the CX-5 has standard Rear Cross Traffic Alert, helping the driver avoid collisions. GMC charges extra for Rear Cross Traffic Alert on the Terrain.
The CX-5 Turbo Signature’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 Terrain doesn’t offer a driver alert monitor.
Both the CX-5 and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mazda CX-5 is safer than the GMC Terrain:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mazda CX-5 is much safer than the Terrain:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the CX-5 the rating of “Top Safety Pick” for 2023, a rating granted to only 98 vehicles tested by the IIHS. The Terrain last would have qualified as a “Top Safety Pick” in 2017.
