2025 Mercedes-Benz EQS SUV Problems: 7 Known Issues

On the 2023-2025 Mercedes-Benz EQS SUV, owners repeatedly report that the EQS SUV will charge normally on Level 1 and Level 2 AC but throws a charging fault and disconnects within seconds to minutes on high-power CCS DC stations (Electrify America, EVgo 150-350 kW), while sometimes still working on 50 kW units. The failure traces to the DC charging control unit / HV charging interface rather than the pack itself - multiple owners had the DC control unit replaced (some more than once) before the fault cleared, and at least one had an entire HV battery swapped without fixing it. A related trigger is the Plug-and-Charge handshake: several owners found that starting the session from the Mercedes me app instead of Plug-and-Charge avoids the abort.

On the 2023-2025 Mercedes-Benz EQS SUV, the EQS SUV's 12V auxiliary battery supports the entire low-voltage network - Hyperscreen, door handles, locks, and the contactors that connect the HV pack. On early X296 software the DC/DC converter did not reliably top up the 12V battery while the vehicle was parked, so cars left standing (or driven only short distances) would go completely dead: no display, no door handle presentation, no READY mode, with the 108 kWh pack sitting at 80%+ charge. Dealers commonly blame infrequent driving before diagnosing the parasitic drain or replacing the battery.

On the 2023-2025 Mercedes-Benz EQS SUV, other control units on the EVA2 bus continuously send diagnostic requests to the high-voltage battery management system. The BMS memory overflows, the module shuts down, and the HV contactors open - disconnecting the 108 kWh pack from the drive unit. The result is an instant loss of propulsion at speed with the red turtle icon on the display, even with a nearly full state of charge. NHTSA recall 24V-372 covered 14,912 EQE/EQS sedans and SUVs, and owners reported the failure occurring on freeways before the fix.

On the 2023-2025 Mercedes-Benz EQS SUV, eQS SUV owners report the 56-inch Hyperscreen going black at random - typically after the car has been driven for a while and heat-soaked - with the display sometimes only returning after the vehicle sits switched off for one to two hours. A milder variant is momentary blanking followed by the MB EQ splash screen as the head unit silently reboots. The root cause is a fault in the central multimedia computer; software reloads fix some cars, while others need the head unit replaced under warranty.

On the 2023-2025 Mercedes-Benz EQS SUV, eQS SUV owners consistently report the factory tires - commonly Goodyear Eagle F1 - worn out at 11,000 to 15,000 miles, with the rear axle and especially the right rear wearing fastest. The drivers are the roughly 6,200 lb curb weight, instant motor torque, aggressive rear camber, and the rear-axle steering system, which scrubs the rear tires and accelerates wear further if its alignment or calibration has drifted. Dealers frequently decline warranty coverage on the tires.

On the 2023-2025 Mercedes-Benz EQS SUV Electric, the AIRMATIC air suspension compressor on the EQS SUV produces an audible drone or buzzing noise during ride height adjustments, which is particularly noticeable in the cabin due to the quiet electric drivetrain. The compressor cycles more frequently than expected to maintain ride height under the heavy battery load.

On the 2023-2025 Mercedes-Benz EQS SUV, the EQS SUV's thermal management ties cabin heating and cooling to the HV circuit through a heat pump and high-voltage heat exchanger. The documented failure on the EQS SUV is A/C that works, then blows warm intermittently and cannot be reproduced on demand at the dealer. (Similar heating complaints exist on the EQB and EQS sedan but are not documented on the SUV, so they are excluded here.) Diagnosis is frequently misdirected to refrigerant charge first; documented repairs have included replacement of the high-voltage heat exchanger and, in one case, the full A/C and heating hardware after contamination was found in the coolant lines.
