We recently traded in our 2015 to a 2018 QX60 and found that it has new lighting under the car for the welcome/open the door but it stopped working. The welcome lighting is on in the menu but it still does not work. Any ideas?
I just installed this myself and had a similar issue. I wonder if it takes a while for the control module to reset after starting the car?
This is what is happening with mine after installation :
The welcome lights / handle lights /dome lights turn on when approaching the car
After pressing door unlock, the welcome lights / handle lights turn on and off with the dome lamp
The welcome lights/handle lights and dome lights turn OFF when the car starts.
With the car running and shifter in park, when the door is open the dome lights turn ON, then welcome lights STAY OFF
After turning the car off and opening the door, the dome lights turn ON, the welcome lights STAY OFF
The welcome lighting will NOT turn on and off with the dome lamp anymore with the keyless remote or when approaching the vehicle
The handle lights WILL turn on and off with the keyless remote and when approaching the vehicle.
Not sure this is normal but I also would have expected for them to come on with the handle lights after turning the car off. I am assuming that after they receive the signal to turn off when the car starts, there is a period when they don't respond anymore.
