I had the “Service Suspension” pop up yesterday. Popped up often but very intermittently. (I was surprised how many times the suspension is cycling during a drive!)
The day before I had popped the hood after pulling in the garage. Unfortunately, apparently the suspension was not done doing its whoop-de-dooos before popping the hood. When you pop the hood it “freezes” the suspension where it is, I guess confusing the module. Anyway, message kept popping up and I couldn’t even get to the control screen to change ride height.
30 second disconnect of the negative battery cable and it is back to working fine and like normal.
Thought this might help someone who has these random errors. Now instead of the “Italian tune up” we have to do the “whole car reboot”!
