Both the Blazer EV and Solterra have child safety locks to prevent children from opening the rear doors. The Blazer EV 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 Solterra’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.
Both the Blazer EV and the Solterra have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 around view monitors and driver alert monitors.
The Chevrolet Blazer EV weighs 730 to 1226 pounds more than the Subaru Solterra. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
