I was extremely disappointed driving one for a day. The GX seems like a perfect car for me, a 4Runner that’s better for daily but it was a poor attempt at luxury.
The v8 was smooth, power didn’t feel like a v8 but gas mileage did. Interior looked very out of date (before the new nav)...
Just did both front doors yesterday. Likely that metal rod that comes down into the hole on the actuator. See this video at the marked time: https://www.youtube.com/watch?t=855&v=NgGl87pyhH4&feature=youtu.be
