2023 Mercedes-Benz EQS Problems: 8 Known Issues

On the 2023-2024 Mercedes-Benz EQS, mercedes-Benz USA recalled 31,848 model-year 2023-2024 vehicles built roughly February 6 to November 10, 2023, including the EQS sedan, because 80-amp fuses in the main fuse boxes were manufactured incorrectly and can fail in service. A failed 80-amp fuse can cut power to the electric drivetrain (sudden loss of drive power while driving) or to critical safety systems such as the restraint system and instrument cluster, and Mercedes also cited an increased fire risk. The campaign was botched on some cars: in April 2025 a follow-up recall (25V255000) was filed because technicians had installed fuse boxes not intended for the specific model or variant during the 2024 repair, producing contact interruptions or wrong amperage values and re-creating the loss-of-propulsion risk. EQS owners on MBWorld report multi-week parts waits for the replacement fuse box.

On the 2022-2024 Mercedes-Benz EQS, owners report the 12-volt battery running down so the car will not start or keeps shutting off, including after sitting at a film and tint shop. A Mercedes workshop tip for several current models, including the EQS, covers a 12V message at start-up when fault code U116000 (a bus keep-awake unit was detected) is stored; the tip gives the cause as software updates that need to be performed. Applies to: Pre-facelift EQS sedans (V297), as discussed by owners including a 2022 EQS 580 owner. The workshop tip also covers other Mercedes models (206, 223, 232, 254, 294, 295, 296 platforms).

On the 2022-2023 Mercedes-Benz EQS, the monitoring function of the high-voltage battery might be impaired over time. In certain circumstances the warning that alerts the driver to a battery malfunction might not activate in the event of a fault, which would not comply with FMVSS 305 and could increase the risk of injury. Applies to: Certain 2022-2023 EQS 450, 2022 EQS 450+, 2022-2023 EQS 580 and 2022 AMG EQS 53 built February 14, 2021 to September 8, 2022, per the Part 573 report (September 19, 2023 revision); Mercedes recall 2023070013.

On the 2022-2024 Mercedes-Benz EQS, owners report lower displayed driving range in cold weather. The cited search-result excerpts discuss predicted miles, which are not a measurement of battery capacity or proof of degradation. Applies to pre-facelift EQS V297 sedans, including an EQS 450+ owner report. Search result only; page not opened.

On the 2022-2023 Mercedes-Benz EQS, mercedes found that the driving assistance system control unit software does not meet current specifications. Near uniquely shaped structures that run alongside the road at about 26-33 feet high, such as large overhanging bridge abutments, the car may apply the brakes on its own. Mercedes says the driver remains in control and can override the system at any time. Applies to: Certain 2022-2023 EQS (297 platform), along with C-Class and S-Class; about 24,840 vehicles in total, Mercedes-Benz USA service campaign 2023040017 (May 19, 2023). It is a service campaign, not a safety recall.

On the 2022-2024 Mercedes-Benz EQS, the Acoustic Vehicle Alerting System may have software that plays a noise tone instead of the intended beep tone when reversing. The volume meets requirements, but the sound is not consistent within the model year as FMVSS 141 requires, and emitting a sound other than the intended pedestrian alert theoretically might increase the risk of a crash. Applies to: A small number of 2022-2024 EQS 450+ (10), 2022-2024 EQS 580 4MATIC (4) and 2023-2024 EQS 450 4MATIC (2) sedans built February 21, 2022 to October 22, 2024, selected by software version; Mercedes recall 2025070005. The 2023-2025 EQS SUV is also in this recall.

On the 2022-2024 Mercedes-Benz EQS, owners report the MBUX screens going completely black during a drive, with loss of radio, navigation, phone and some driver-assistance functions, or the home screen restarting. In the reports, the system came back after the car was parked and shut down for a while, or after a dealer reset. Owners with and without the Hyperscreen describe it. Applies to: Pre-facelift EQS sedans (V297), as discussed by an EQS 580 owner and an EQS 450+ owner and in the MBWorld EQS sedan forum. Separate from recall 22V493, which covers a display that stays black at unlock on 16 specific 2022 cars.

On the 2022-2023 Mercedes-Benz EQS, mercedes technical information filed with NHTSA describes two flush door handle faults. On some cars the handle does not retract when the car is locked until locking is repeated, because the handle bracket electronics detect a motor fault. On others the handle must be pulled with increased force to open the door manually, because a turning angle sensor lever is broken. Applies to: EQS (model 297) with code 889 flush door handles. The non-retracting handle document covers cars built up to July 2, 2022; the extra-force document has no build-date limit. The same documents cover other Mercedes models.
