Known issues on the 2015 G550. Certain 2015 G550 vehicles are named in two recalls. The first involves the steering coupling, which may not have been tightened sufficiently; the resulting wear could lead to a loss of steering, and the fix is a replacement coupling. The second targets the emergency call system, where a software fault could let its clock drift from the actual date and time and pass along an inaccurate location. The manual's steering procedures, torque values and diagnostics cover the first area, and its wiring diagrams cover the communication circuits.
