Mercedes-Benz EQE 350 4MATIC V295

The EQE's MBUX system is among the most complex infotainment setups in any car, and many owners report freezing screens, slow boot-ups, dropped CarPlay connections, and random warning messages. Over-the-air updates frequently stall or fail, often requiring specific conditions (charge above 70%, car locked, parked with brake set) to complete. When OTA fails, a dealer visit is needed for a manual software flash. A steering-wheel soft reset (hold phone + voice buttons 15-20 seconds) resolves temporary glitches without losing saved settings. While most software issues cost nothing if under warranty, out-of-warranty diagnostic fees and MBUX hardware module replacements can reach €300-500. Mercedes has improved software stability through successive updates, and later-production cars (mid-2024 onward) are generally better.

A recurring issue across the Mercedes EQ range. The EQE's numerous always-on modules (telematics, keyless entry, connectivity) can drain the small 12V auxiliary battery within 1-2 weeks if the car is not driven or plugged in. Symptoms include an unresponsive dashboard, inability to shift out of Park, and 'Malfunction - stop vehicle' warnings. A 2024 recall addressed battery management software on affected cars, but the underlying parasitic drain from connected services persists. Disabling Mercedes Me Connect features, turning off the SmartKey proximity scan, and keeping the car plugged in when parked for extended periods helps prevent this. Replacement of the 12V battery costs €200-400 at a dealer, and many owners have needed it replaced within the first 2-3 years.

Mercedes recalled 24,873 EQE and EQS vehicles worldwide (3,699 in Germany) for a BMS software defect that can unexpectedly shut down the high-voltage battery, resulting in a sudden loss of drive power. Affected vehicles were produced between February 2023 and May 2024. The fix is a free dealer software update. On a used car, verify via VIN that this critical recall has been completed. If the recall was missed and the fault occurs out of warranty, diagnostic costs may apply, though Mercedes has covered the software update regardless of warranty status for this safety issue.

The EQE's extensive driver-assist suite (adaptive cruise, lane-centering, blind-spot intervention, automated parking) relies on multiple cameras and radar sensors. Owners report false warnings in bad weather, jumpy lane-keeping that tugs the steering wheel during gentle lane changes, and intermittent loss of functions requiring dealer visits. After any windshield replacement, full ADAS recalibration is mandatory (€200-500). If a radar or camera sensor fails, replacement costs €500-1,500 including recalibration. Road grime, ice, and film on sensor apertures can trigger phantom warnings, so regular cleaning of the sensor windows is important. Most issues are resolved through software updates, but persistent sensor failures outside warranty can be costly.

At 2,450 kg, the EQE 350 4MATIC is heavy, and the instant torque delivery accelerates tire wear significantly compared to combustion equivalents. Forum reports indicate front tires reaching the wear limit at 15,000-25,000 km, especially on cars with 20-inch or 21-inch wheels. Rear tires last somewhat longer but uneven wear patterns are common. EV-specific tires (Bridgestone Turanza EV, Michelin e.Primacy) help extend life. Regular alignment checks are essential. A set of four 19-inch EV tires costs €600-900 in Europe, or €800-1,200 for 20/21-inch sizes. This is partly accounted for in fixed costs, but premature wear beyond normal expectations pushes additional cost into risk territory.

The EQE sedan offers AIRMATIC air suspension as an option (standard on the AMG variant). When equipped, the typical failure mode is a slow leak in the rubber air spring, causing one corner to sag when parked overnight but rising back to normal height after starting. Replacement cost is approximately €1,200-1,800 per strut at a dealer, and it is recommended to replace struts in pairs. A failing compressor adds another €800-1,200. This issue is well-documented on Mercedes models with AIRMATIC and typically appears after 60,000-100,000 km. Cars with standard steel suspension are not affected.

Mercedes recalled approximately 32,000 vehicles across multiple models (including the 2023-2024 EQE 350) for incorrectly manufactured 80-amp fuses that could fail, potentially causing sudden loss of drive power, disabled safety systems, blank instrument clusters, or in rare cases, an increased fire risk. The fix is a free fuse box replacement at a dealer. This is a safety recall that should be verified as completed on any used EQE before purchase.

Some EQE owners report intermittent HVAC failures where the air conditioning or heating stops producing temperature-controlled air despite the fans running. The heat pump system is efficient but complex, and issues can stem from a low refrigerant charge, stuck blend doors, a faulty expansion valve (€200-600 to replace), or software mismanagement of the thermal system. In cold weather, the heat pump may produce air that feels cool even when the system is working correctly, as it targets cabin temperature rather than vent temperature. Full compressor replacement, if needed, costs €800-1,200.
