same thing just happened to me last night... car had been jacked up for 2 months, I put all 4 wheels on the ground and I tested my electric SLS motor and both struts leaked major fluid... (they were not leaking before)
I jacked the car back up, then down again, the left rear stopped leaking, but the right continued, I cycled the suspension repeatedly using the SLS, but the leak on the right rear continues...
