What's wrong?
The 12-volt ground connection under the driver's seat on affected 2021-2022 Mercedes-Benz Gle 450 and Gle 350 vehicles is part of the electrical return path. It helps the battery system complete the circuit that powers and monitors vehicle electronics. The connection depends on a bolted joint being tightened to the correct torque so current flows cleanly through the contact point.
On these vehicles, a production rework step was not completed correctly. The bolt for the ground connection was left without the required tightness. A loose ground creates extra resistance at the joint, and that resistance can build heat around the connection. If the connection overheats, the vehicle can show electrical problems and fail to start.
Mercedes-Benz says the driver will not receive a warning before this happens. There is no warning sign before failure, so a battery warning message or a no-start condition means the electrical system already needs dealer attention.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the 12-volt ground connection under the driver seat and secures it if needed. The inspection, repair, parts, and labor are free under the recall. Mercedes-Benz is not offering a separate reimbursement program because the involved vehicles were not previously subject to this condition and remain covered under the new vehicle warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
