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 UX 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.
Using vehicle speed sensors and seat sensors, smart airbags in the UX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The UX’s side airbags will shut off if a child is leaning against the door. The Model Y’s side airbags don’t have smart features and will always deploy full force.
The UX has standard Whiplash Injury Lessening Front Seatbacks, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Front Seatbacks system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Model Y doesn’t offer a whiplash protection system.
The UX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Model Y doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To help make backing out of a parking space safer, the UX’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engages the brakes to help avoid a collision. The Model Y doesn’t offer a rear cross-path warning system.
The UX’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 UX has standard Safety Connect®, which uses a global positioning satellite (GPS) receiver and a cellular system to 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 UX and the Model Y 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, available all wheel drive and rear parking sensors.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH, results indicate that the Lexus UX is safer than the Tesla Model Y:
