What can fail
Water can collect in the spare tire wheel well and damage the fuel pump control unit, potentially causing the engine to stall while driving.
The 2020 Mercedes-Benz AMG GLE63 has 3 recalls, the most serious being a water intrusion issue in the spare tire well that can damage the fuel pump control unit and cause the engine to stall without warning while driving.
Water that pools in the spare tire wheel well can reach and corrode the fuel pump control unit, cutting fuel delivery and killing the engine unexpectedly at any speed. Beyond the stall itself, losing power while in traffic removes engine braking and can make the vehicle harder to maneuver to safety. The two remaining recalls both involve the automatic emergency call system, which contacts first responders after a crash. In one case, the system can send the wrong location to emergency services, meaning help may be directed elsewhere after an accident. In the other, the system can fail to connect at all, leaving occupants unable to reach emergency services if they cannot call on their own. Together, these issues mean that in the event of a serious collision, the automatic safety net intended to summon help may either misdirect responders or go silent entirely.
