We keep getting a suspension failure warning at random times. I've had had it sitting still, driving down the road or anytime inbetween. At first I thought we hit the suspension adjustment switch, but that isn't it.
Went through this about 2 months ago. I'd notice it moving around at lights. Sometimes I'd get several faults within just a few minutes. On and off and on and off.
To help diagnose, I'd keep the nav screen on the 4x4 Info. If it was acting up, I could see that one of the wheels would show a full up or full down on the height. It would just look like a glitch. Sometimes the screen might not show a full high/low condition, but while sitting at a light one of the wheels would move up and down quite a bit. So I was leaning towards suspension height sensors. When I took it to the dealer I mentioned this, so they started looking at the sensors and replaced the (2) rear sensors.
Bad part is I think they screwed up the ride height calibration as the RRS sits consistently 5/8" lower on the right side(I've checked in different modes, different flat surfaces, different fuel loads) - plus my steering is cocked to the left. It's going back next week to look at this - I just didn't have time to address this after the last service due to a fam emergency.
