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 Ioniq 5 are reminded to check the back seat if they opened the rear door before starting out. The Model Y doesn’t offer a back seat reminder.
When descending a steep, off-road slope, the Ioniq 5’s standard Downhill Brake Control allows you to creep down safely. The Model Y doesn’t offer Downhill Brake Control.
The Ioniq 5 Limited has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Model Y only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the Ioniq 5’s standard Rear Cross-Traffic Collision Warning uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. The Model Y doesn’t offer a rear cross-path warning system.
The Ioniq 5’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 Model Y doesn’t offer a driver alert monitor.
The Ioniq 5 has standard Blue Link, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model Y doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Ioniq 5 and the Model Y have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front 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 and rearview cameras.
