The Mazda CX-30 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Forester doesn’t offer a front passenger side knee airbag.
The CX-30 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 Forester’s blind spot costs extra.
To help make backing out of a parking space safer, the CX-30 has standard Rear Cross Traffic Alert and Smart Braking Support - Rear Crossing on the Preferred/Carbon/Aire/Premium automatically engages the brakes to help avoid a collision. Subaru charges extra for Rear Cross Traffic Alert on the Forester and its not available on the Base and the Forester’s Rear Cross Traffic Alert does not include automatic braking.
Both the CX-30 and the Forester have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the CX-30 is 1.9% to 2.7% less likely to roll over than the Forester.
The Mazda CX-30 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Forester is only a standard “Top Safety Pick” for 2025.
