RepairPal Expert Overview:
Mercedes-Benz is recalling certain model year 2011 G550 and G55 (AMG) vehicles manufactured from September 20, 2010, through April 27, 2011. If the front passenger airbag were to deploy, parts of its molding strip could become loose and become a projectile in the passenger compartment. This projectile would increase the risk of personal injury during airbag deployment. Dealers will reinforce the connection between the molding strip and airbag cover flap to correct this concern.
2011 Mercedes-Benz G55 AMG Reviews
I have a 2011 G55 AMG. The horn and steering wheel instruments intermittently fail to operate for long periods of time. The Mercedes dealership in Fort lauderdale refused to even look at the problem since the steering wheel instruments worked the days that I took it in. Also the seat lumbar support pump on the passenger side keeps going on and off (possible leak). Finally when the vehicle goes from reverse to drive it has a 3-5 second hesitation before engaging. The dealership said that this is normal for this model.
Overall the horn issue and the transmission issue are safety issues, very dissapointed at the dealer response (Fort Lauderdale Mercedes).
