The NHTSA awarded the Grand Highlander five stars and the IIHS designated it a Top Safety Pick+; however, 

the Grand Highlander has not yet undergone evaluation by either organization. 

However, both safety agencies ranked the Highlander highest on their safety rankings. 

This will be revised once accident testing on the larger Grand Highlander is complete. 

Standard and optional driver-assist technology contribute an additional point to the 2024 Highlander's total score.  

An additional innovation introduced in 2024 is a driver monitoring system capable of halting the vehicle in the event that the driver fails to respond.
