What's wrong?
The 48V ground connection under the front passenger seat is part of the electrical return path for the onboard power supply. Its nut and bolt are supposed to clamp the ground cable tightly to the vehicle body, so current moves through the cable without extra resistance or heat.
On affected 2020-2022 Mercedes-Benz GLE and GLS SUVs, production rework left that ground connection tightened below the required torque. A loose connection raises electrical resistance at the cable end. That resistance creates heat, so the cable at that point can overheat instead of carrying current cleanly.
There is no warning sign before the connection starts to fail. When the failure happens, the instrument cluster displays messages tied to the 48V onboard power supply. Treat those messages as a sign that the ground connection has already lost the tight electrical contact it needs.
Who's affected?
The scope spans GLE, GLS, AMG, and Maybach variants from 2020, 2021, and 2022, all tied to the same under-dash wiring ground connection.

What's the safety risk?
An overheated electrical cable can increase the risk of a fire. There is no warning before the cable overheats. If warning messages appear in the instrument cluster about the 48V onboard power supply, pull over when safe and call the dealer. Repair is free at any franchised Mercedes-Benz dealer.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the ground cable bolt for the 48V ground connection under the front passenger seat and tightens it when needed. Parts and labor are covered under the recall. Mercedes-Benz is not offering a separate reimbursement program because all affected vehicles remain covered under the new vehicle warranty. If you have prior repair paperwork, ask the service desk how that warranty coverage applies.
