The QX80’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Suburban’s rear power window switches have to be held the entire time to close them fully.

On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Suburban can only operate the windows from inside the vehicle, with the ignition on.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The QX80 offers available headlight washers to keep headlight output high. The Suburban doesn’t offer headlight washers.
