Air bags
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?

Service brakes
Was driving my vehicle on the freeway and pulled off on and exit ramp. Brake pedal went to floor with very little braking had to pump the brake pedal to regain control. Brakes felt soft. Returned home by pumping brakes. No warning lights, Next day bled brakes and replaced brake fluid. Function restored but no cause could be identified for the air in the brake lines. Very disturbing and unsafe. Sounds very much like 22V315000.
