The Lexus NX is a luxury compact crossover sold by Lexus, the luxury division of Toyota. It was introduced in late 2014 as an all-new, entry-level crossover model in Lexus' lineup, slotted below the mid-size RX crossover. The name NX stands for Nimble Crossover.
Hi @maryann43656
What is the year of the vehicle?
Does the vehicle have a manual rear door, a power rear door or a power rear door with a kick sensor?
If the vehicle has a kick sensor and it isn't working check that it hasn't been turned off in Settings
Go to Settings > Vehicle customize > Door Control > Hands free and check
