Mercedes-Benz EQE AMG 43 4MATIC V295

The EQE AMG 43 uses the same MBUX system as the EQS, and it shares the same software instability on early production cars. Owners report screens going black during driving, navigation disappearing mid-route, and over-the-air updates getting stuck at 80-90% and never completing. A soft reset (holding phone + voice buttons for 15-20 seconds) fixes temporary freezes, but persistent issues may require a dealer visit for a full software flash (3-23 hours depending on scope). If the central MBUX control unit hardware fails, replacement costs €1,500-2,500. Cars built from mid-2024 onward with updated software show significant improvement. The optional MBUX Hyperscreen (three displays under one glass panel) adds further complexity but uses the same underlying software.

Mercedes recalled 14,912 EQE and EQS vehicles (2023-2025 production) after discovering the battery management system software could cause the high-voltage battery to shut down without warning. This results in complete loss of propulsion while driving. The fix is a dealer-applied software update that cannot be performed over-the-air. In Germany alone, 3,699 units were affected (KBA recall no. 012871). A separate earlier recall covered 8,281 units of 2022-2023 models for a related drivetrain software fault. Mercedes reported only two field incidents in the US with no injuries. If the recall is completed, there is no ongoing cost. If the software triggers a fault that damages control modules, diagnosis and repair could cost €300-500.

Mercedes recalled nearly 32,000 vehicles across multiple models (including the EQE) for an improperly manufactured 80-Amp fuse in the main fuse box. Affected vehicles were assembled between February and November 2023. If the fuse fails, it can cause loss of drive power, instrument cluster failure, restraint system malfunction, or in a worst case, increased fire risk. Mercedes stated there were no reported warranty claims or injuries. The fix involves replacing the main fuse box at a dealer, which is covered by the recall. Outside the recall, fuse box replacement costs €200-600 including labor.

The EQE AMG 43 uses AMG-tuned AIRMATIC air suspension on all four corners. Common failure modes include leaking air struts (rubber seals become brittle with age, causing hissing and uneven ride height), compressor failure from moisture ingress, and faulty height sensors. A single air spring replacement costs €1,500-2,000 including labor, while the compressor runs €1,000-1,500. If moisture from a failed compressor spreads to air springs, multiple components can fail together, pushing costs to €4,000-5,000. AIRMATIC components typically last 8-12 years or 100,000-150,000 km. Current EQE AMGs are relatively young, so these failures are not yet widespread, but they represent the largest potential repair cost as the car ages.

The EQE relies on a 12V battery to wake the computers, release the parking pawl, and close the high-voltage contactors. With dozens of electronic control units drawing standby power (telematics, SmartKey polling, MBUX), the 12V system can drain completely within one to two weeks of inactivity. Symptoms include 'Malfunction - stop vehicle' warnings, an instrument cluster that will not boot, or inability to unlock the doors. Mercedes has issued software updates that improve 12V charging management and sleep behavior. Replacement of the 12V battery costs €300-600 including SAM module programming. Disabling SmartKey polling via the key fob reduces drain. Prevention: keep the car plugged in when parked for extended periods.

Some EQE owners report AC charging stopping mid-session, DC fast charging handshake failures with certain networks, or the charging port door becoming stuck. The CCS DC connector can become misaligned if a public charger overheats during a session, damaging the vehicle's pins. In one documented case, a charging port replacement cost approximately €650 for parts plus €1,800 in labor. The on-board AC/DC converter module replacement runs €1,200-2,500. A stuck charging port door actuator is a cheaper fix at €200-400. Many charging issues are software-related and resolved by updates. There is a manual release cable near the rear fuse box for a stuck charging flap.

A widely reported issue across the Mercedes EQ range. The forward collision avoidance system can trigger sudden, hard braking at speeds above 70 km/h with nothing ahead. Owners also report abrupt braking while reversing in parking areas. Mercedes has stated this falls under normal system operation and has not issued a specific recall. Some owners change the emergency braking sensitivity from 'normal' to 'late' or disable it, though it re-enables at each ignition cycle. The braking itself causes no direct repair cost, but any resulting rear-end collision from the unexpected stop would. Road grime, ice, or residue on radar and camera apertures can trigger false readings. Cars from 2024 onward with updated sensor calibration show fewer incidents.

Mercedes has issued a Technical Service Bulletin (April 2026) for creaking noises in irregular sequences when driving slowly with slight steering movements. The root cause is the contact area between the wheel bearing and steering knuckle. The repair involves cleaning the contact surfaces and applying Molykote coating. This is a cosmetic annoyance rather than a safety issue, and is typically addressed under warranty or goodwill. Out of warranty, parts and labor run €200-600 depending on whether the bearing needs replacement or just the surface treatment.
