The mercedes cl & sl classes have the same front seats with an integrated seat belt system. Since it was only connected to the seat, the seat failed without even a bruise to my right shoulder (by over 30-40 degrees). I was left against the dash board (with my seatbelt on) throwing limbs at my survival.
Upon impact impact side air bag did not deploy. Consumer notice mercedes benz body service, no response as to why?
