NHTSA Complaint #11446422 — 2021 MERCEDES-BENZ AMG GLE53

It is incredibly distressing to have experienced an issue that is widely reported in this database and online forums, and remains unaddressed by MBUSA. It also seems to be an entirely preventable issue that can be fixed via a software update. The issue relates to a malfunction of the 48V battery that made the vehicle inoperatable. It happened in the midst of winter and we would be been in a dire position if our family did not come to the rescue to pick us up. The vehicle had to be towed to a dealership. Here is the dealer summary: 48v software vehicle has no power, connected jumper, battery lights on in dash, towed into shop and connected battery charger, performed quick test, found codes in 48v- B183349 and B183371 , referred to Topic # LI54.10-P-069698 remedy #2, performed guided test for B1833349, as per guided test updated 48v software and commissioned, after completion vehicle started normally, performed extended test drive and multiple short test drives to verify vehicle now operating as designed again, lights no longer present in dash.
