In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Prius Prime are reminded to check the back seat if they opened the rear door before starting out. The ID.4 doesn’t offer a back seat reminder.
Both the Prius Prime and the ID.4 have standard driver and passenger frontal airbags, front side-impact 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Toyota Prius Prime 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 ID.4 has not yet been fully evaluated by the IIHS for 2024.
