What can fail
The 2021 Mercedes-Benz AMG GLE63 has 6 recalls, the most serious being two separate fire risks: a misrouted air conditioning drain hose that can flood the footwells with water, corroding wiring and causing short circuits, and a loose ground cable bolt under the front passenger seat that can cause a 48-volt electrical cable to overheat.
On the occupant safety side, the middle rear seat belt buckle can slip down into the gap beneath the seat cushion during buckling. If it cannot be retrieved, that seating position has no working restraint, leaving a rear passenger unprotected in a crash. There is also a headlight concern: LED headlights may have been set to an incorrect aim during a prior service visit, which can cut down on road illumination at night or throw light into oncoming drivers' eyes, raising the risk of a collision. Two recalls cover the automatic crash notification system, which contacts emergency services after a collision. In one case the system can transmit an incorrect location, potentially sending responders to the wrong place; in the other the system can fail to connect entirely, delaying any emergency response. Because both issues affect the same automatic distress call feature, prior repair attempts for one aspect of the problem may not address the other. Owners of this vehicle should verify with their dealer whether both eCall concerns have been resolved.
