I've had my Model S going on 5 weeks now, and I got a message this morning after the car was sitting for a day in the garage that "Air Suspension Needs Service". I couldn't get the suspension to raise or lower (makes sense given the error). I tried a hard reboot, but the issue persisted. I drove about 10 miles, then did a full shutdown via the touch screen (Power Off), and then 5 minutes later started the car again with the brake pedal. The issue is now gone, and my air suspension raises and lowers normally. Doing some research, there are multiple people spanning years back, that get this error message. Since the issue seems resolved and the air suspension is working again, should I cancel the service center appointment? I am thinking of still taking it in to let them at least run diagnostics and see what was wrong. Look forward to hearing anyone else who may have had this on their Tesla.
