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?

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.
In the past several weeks, whenever I press on the brake pedal firmly at a stoplight or even on the highway, the "low brake light" alarm on the vehicle turns on. I went and checked the brake fluid level, but it is normal. It also seems to take longer to brake the car than before. I'm not sure if it is related to the recent recall or not.
The GL450 has the balance shaft problem .It skipped timing and caused major engine failure.. This problem is prevalent for the M273 engine. The parts wear prematurely. The timing is affected and the 4 cam power train misaligns. The engine quits and the repair is usually over 4000.00. It produces 1208 1200 codes along with misfire codes. I feel Mercedes Benz Corp is responsible and has liability for the loss. Thank You. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
