I would like to report 3 issues. One, happened yesterday, XXX. Driving on [XXX], in clear weather, no obstacles, no vehicles around, the vehicle engaged emergency breaking and pulled seatbelts as if there was an imminent crash. Second issue, the carpet behind rear doors is separating on both sides, preventing the rear doors from closing normally and it is catching the seatbelt prong. Third issue, the handles retract when children are trying to open the doors, catching their fingers while retracting and causing minor injuries.

The electric refrigerant compressor on my 2023 Mercedes-Benz EQS 580 4MATIC SUV failed without warning. On this vehicle, the compressor is a dual-function safety-critical component: it provides cabin air conditioning and, more importantly, active cooling for the high-voltage lithium-ion battery pack. I am filing this complaint because a single-point failure in a component responsible for high-voltage battery cooling should not occur on a vehicle of this age and mileage, and because owners receive inadequate warning of the safety consequences when it does. I request that NHTSA investigate the failure rate of the electric refrigerant compressor on 2022–2024 EQS-platform vehicles and evaluate whether the battery thermal management design provides adequate redundancy and driver warning The vehicle was taken to an authorized Mercedes-Benz dealer, which confirmed the refrigerant compressor failure and replacing the compressor under warranty. Parts are backordered per Mercedes. The vehicle has been off the road for 28 days The dealer did indicate awareness of similar failures on other EQS vehicles.

There are several issue with the 2024 Mercedes EQS. I had the car have a full system failure and stop in the middle of the road with no warning. It could not even be towed. Apparently coolant was leaking without any warning. This caused a complete system failure- car wouldn't power on, couldn't be towed, couldn't be pushed to a safe location- nothing. The next most concerning issue is car automatically locks itself within seconds and with the key inside and with a passenger inside. My baby was trapped in the car. I came out of the driver seat and the key was in my purse. This could've resulted in a fatal incident. I live in [XXX] where we have a lot of heat. What if my key and phone were both in the car and my daughter was trapped. The car has locked automatically with key still in the car on multiple occasions. The car shuts off on its own within 2 minutes while passengers are inside. Again, as a parent this is deeply concerning and can lead to a fatal incident and overheating The lane correction is extremely harsh and many times wrong pulling the car in the wrong direction and with a lot of force INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My Mercedes EQS SUV has experienced repeated safety-related defects. The brakes have intermittently locked up while driving, creating a serious safety concern. The vehicle also vibrates at highway speeds on the freeway. These issues have occurred on two separate occasions. Despite multiple service visits, the dealership has been unable to diagnose or repair the problems. During the first incident, they reset the software. During the most recent incident, multiple software error warnings appeared simultaneously, indicating system malfunctions (see images for documentation). The vehicle has now been at the Mercedes service center for over two weeks, with required parts on backorder from Mercedes and no estimated repair timeline provided.

The contact owns a 2023 Mercedes-Benz EQS580 4Matic. The contact stated that the vehicle was designed with Level 2 Semi-Autonomous Driving System and was purchased brand new. The contact stated that the first failure had occurred in the first month of purchase. The contact stated that while driving with the Adaptive Cruise Control with the Stop-and-Go Mode engaged, the set speed changed radically. The contact stated that while the speed was set to 60 MPH, the speed decelerated to 20 MPH unintendedly. No warning light was illuminated. The vehicle was taken to the dealer, but the cause of the failure could not be determined. The contact stated that a staff at the dealer advised the contact that it was a known issue with similar vehicles. The contact stated that the failure recurred while the dealer was test-driving the vehicle. The vehicle was not repaired. The contact stated that the failure persisted. The contact stated that upon taking the vehicle back to several dealers on several occasions and the contact was provided a loaner vehicle; however, the same failure occurred with the loaner vehicles. The manufacturer was not notified of the failure. The failure mileage was approximately 200.

Complaint When switching the front passenger display on and off, sporadic images may be shown that are similar to stains on the display. This complaint need not be a permanent one, it may disappear again on its own. Attachments 1648459315482 (1).jpg 1648459315528.jpg Cause Implausible video transfer from head unit during start and switch‑off sequence. These images (artifacts) are of a purely cosmetic nature only and they do not impair the function. Remedy Software update of MBUX (A26/17) to software release E316.5 or higher.

This complaint need not be a permanent one, it may disappear again on its own. Cause Implausible video transfer from head unit during start and switch‑off sequence. These images (artifacts) are of a purely cosmetic nature only and they do not impair the function. Remedy Software update of MBUX (A26/17) to software release E316.5 or higher.

Issue A software update will be performed that provides enhancements to the robustness and system stability of the communication module. The update is free of charge and runs in the background, which takes about 8 minutes to install. During this time, the vehicle can be driven without any restrictions, and the new software will be active with the next ignition cycle. Remedy MBUSA will conduct an OTA service campaign. Remote software updates are automatically downloaded and installed in the customer’s vehicle free of charge and do not require a dealer visit.

Complaint Slight creaking noises when steering. Cause Noises may come from one or more sleeves of the horn contact plate. Remedy Remove the horn contact plate and check the sleeves for noise; see attached video. If necessary, apply lubricant to the sleeves.

Complaint Repeat workshop visit for vehicle vibration while braking from 60MPH. NOTE: Although the symptom is similar to a tire or wheel vibration, it is usually readily noticeable that it is distinctly different if it happens at all times or only while braking. Cause Although the cause of the vibration is most likely due to excessive lateral runout on the rotor or hub/wheel bearing, the system as a whole needs to be checked for other possible contributors. 1. Prior collision damage. 2. Excessive vehicle sitting times without rotating components. 3. Wheel bearing/hub lateral runout. 4. Wheel mating interface has been overtightened (did not follow WIS torque procedures). 5. Mating interfaces have been excessively modified (painted, gouged, bent, etc...). Remedy Read through the entire attached worksheet prior to performing. After performing, please review the final page and perform work accordingly. NOTE: This document is not pre‑authorization or otherwise dealing with warranty. This is intended for diagnostic purposes only. If there are any questions on how to proceed OR The work sheet has been performed and the vehicle has returned with the same concern. Please perform the measurements as seen in the worksheet again and open a TIPS case to the Body, Chassis, and Entertainment team.
