general problems of the 2007 Mercedes Benz GL450

The steering wheel airbag spontaneously deployed with no prior warning sensors activated or collision (moments after pulling into driveway at home). Mercedes benz refuses to take any responsibility, or at least inspect and replace the steering wheel and airbag. Driver's arm was partially injured due to deployment, not severe. However the concern remains of whether this could have deployed while driving, causing critical injuries. Should we worry about the remaining airbags spontaneously deploying?.

Mercedes Gl450 the front end started riding low after driving it and would then adjust itself, which was very noticeable not the minute amount is supposed to do just for aerodynamics. Then it started out low from a parking position and once on the road it would raise a little to where it was drivable that went on for two days I had an appointment to get it inspected and on the third day the front end just lowered itself and the whole car was very unstable jumped up and down because of tbe great difference between the front and back I was driving on a one lane road on a mountainous region which is where I live and had nowhere to pull over. I made it after driving at 30 mph on a 45 mph zone, front air suspension struts that were leaking and told me this car was notorious for this problem. I need you to please look into this o believe it is a hazardous dangerous problem with this vehicle!.
