What the fix does
This page covers 11 recalls and 14 owner complaints for the 2022 Mercedes-Benz Gle 450.
Complaints about the 2022 GLE 450 center heavily on the engine and powertrain. Owners most often describe unexpected power loss while driving, the vehicle suddenly shuts down or loses propulsion without warning, sometimes accompanied by multiple warning lights. Several owners report a 48-volt system malfunction message appearing during these events, and at least a few say restarting the vehicle temporarily resolved the issue, though the root cause went undiagnosed at the dealer. A separate but related complaint describes the vehicle being unable to accelerate beyond 20–25 mph even with the accelerator fully depressed, making highway driving impractical. Electrical system complaints add to the picture of intermittent failures. A single report describes a roof glass panel shattering spontaneously while the vehicle was parked, with no apparent impact involved.

Crash-Related
By System
The 2022 Mercedes-Benz GLE 450 has 11 recalls, the most serious involving a steering coupling screw that can loosen and fall away from the steering gear, causing a complete loss of steering control.
Several recalls point to fire risks from electrical wiring under the front seats. Loose ground connections tied to both the 12-volt and 48-volt systems can overheat, and prior repair attempts did not fully resolve the issue across all affected vehicles. On the fuel system side, the fuel pump can shut down without warning and cut drive power while the vehicle is moving. The transmission also has a separate issue where it can fail to fully downshift in certain conditions, stalling the engine. A wiring harness for the front acceleration sensor may be routed incorrectly, which can prevent the front airbags from deploying in a crash. The automatic emergency call system can become disabled, preventing contact with emergency services after a collision. Finally, rear door window trim bars can detach while driving and become a road hazard for other vehicles.
