2013 Mercedes-Benz SL550 QuestionsTruck will not open automatically only opens with the mechanical key (1 answer)
I opened it once using the inside button but now it is locked and will only open with the mechanical key not with the smart key or the inside button.

2013 Mercedes-Benz SL550 RecallsPower Steering Assistance Fails
The electric power steering system may have improperly soldered contacts inside the control unit. This could result in the power assist failing while driving. Dealers will replace the electric power steering control unit free of charge to resolve the concern.
The occupant detection system may unintentionally shut off the passenger front air bag due to a sensitivity issue in the sensor mounted within the passenger seat cushion. Dealers will replace the passenger side seat cushion which includes the sensor free of charge to resolve the concern.
These vehicles are equipped with a new type of A/C refrigerant - R1234yf. Testing has determined that escaping R1234yf refrigerant may ignite under specific conditions. A severe frontal crash may rupture one of the air conditioner refrigerant lines, which can result in a gaseous mixture of refrigerant being released into the engine compartment. The resulting fire could spread to additional combustible materials. Dealers will replace the R1234yf refrigerant with R134a (which is the type that had been used previously) along with new refrigerant lines (hoses) designed specifically for R134a.
