[2023] While the vehicle was stationary and connected to a DC Fast Charging station (Electrify America), a thermal event occurred at the charging interface. The charging connector overheated and thermally fused (welded) to the vehicle's high-voltage charging inlet. The connector could not be released by the vehicle or the station. A technician dispatched by the charging network was unable to remove the

Charging System

[2023] I recently noticed that the charging port is showing signs of melting, which is both concerning and potentially hazardous. This issue is affecting the functionality and safety of my vehicle, and I am deeply disappointed that such a problem has occurred. The charging port is a critical component of the high-voltage system. Its failure poses significant safety concerns such as overheating, sparking,

Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.

Known issues

High

2024 EQE / EQS traction-battery recall (NHTSA 24V-372) covered a high-voltage pack issue affecting EQE 350/500 and shared EQS architecture; Mercedes repaired affected vehicles free of charge.

NHTSA recall

Low

EQS Sedan launched 2022 with software-related range-prediction quirks; OTA updates resolved most reports.

Owner-fleet data

Low

DC fast charging up to 200 kW is well-engineered; sustained sessions hold rate longer than most peers because of conservative thermal management.

Owner-fleet data
