2022 Mercedes-Benz EQS 580 4MATIC

Repeated unintended automatic emergency braking XXX – Small animal: While driving, the vehicle initiated an emergency braking event because it detected a rat. The braking was sufficiently aggressive that it nearly caused an accident, there were vehicles following closely behind at the time. XXX – Moped: The vehicle slammed on its brakes when a moped drifted slightly into my lane, despite there being no apparent imminent collision. XXX – Parking lot: While reversing into a supermarket parking space, the vehicle applied emergency braking even though there was nobody else around. XXX – Home driveway: While reversing into my garage, the vehicle initiated an emergency stop despite there being nothing behind it. XXX – Highway: While traveling on [XXX] and passing another vehicle with DISTRONIC adaptive cruise control activated, the EQS suddenly slammed on its brakes. There was nothing in front of the vehicle that appeared to justify this action. XXX – Highway: The vehicle suddenly applied emergency braking on the highway despite there being no vehicle in front of me. Another vehicle was directly behind me, creating a significant rear-end collision risk. DISTRONIC adaptive cruise control does not maintain the selected following distance When another vehicle moves into the space between my vehicle and the vehicle ahead, DISTRONIC does not reliably increase the following distance to restore the selected gap. Instead, the EQS sometimes continues following too closely or accelerates into the available space, getting even closer to the vehicle ahead. This behavior has occurred repeatedly and has contributed to situations in which the vehicle subsequently applies hard braking. It creates a potentially dangerous chain of events involving insufficient following distance, unexpected acceleration, and sudden braking. Video of the issue...

I am formally reporting a serious and potentially life-threatening safety issue with this vehicle and requesting an immediate investigation and recall consideration. On 09/21/2026 at approximately 5:05 PM, I was driving along with my wife on westbound Tennyson Road in Hayward during heavy traffic, the vehicle suddenly stopped without warning and multiple warning lights and indicators appeared. Fortunately, the vehicle behind us did not collide with us, as this could have resulted in serious injury or loss of life. A similar sudden-stop incident occurred 3–4 months ago outside our home at low speed, which we initially believed was an isolated mistake, but the recurrence now raises serious concerns about a possible safety defect. We cannot risk our lives by continuing to drive a vehicle that can suddenly stop without warning, particularly because the consequences could be catastrophic if this occurred on a freeway at high speed. We request an immediate diagnostic investigation, a written explanation of the cause, confirmation of whether the vehicle is safe to operate, and urgent review for a safety recall. This should be treated as a formal, potentially life-threatening safety complaint requiring immediate corrective action. 1.Immediately investigate this safety 2.Determine whether this is a known or recurring defect affecting this vehicle or other vehicles of the same model/year. 3.Provide a complete diagnostic inspection and written explanation of what caused the sudden shutdown. 4.Confirm what immediate steps must be taken to ensure the vehicle is safe to operate. 5.Escalate this matter for an urgent safety review and recall consideration if this defect can cause sudden loss of vehicle operation. This matter requires urgent attention and immediate corrective action

Tires being designated as the preferred tires via Mercedes are Bridgestone Turanza LS100 265/40R21 These tires go from new to under 3" of thread left, how is this possible. Yes EV vehicles are heavy but its clear these tire are not made sufficient enough to handle this vehicle. In addition to having to change all tires within less than 9,000 miles. The mercedes dealership in 2 different locations say that is normal!. one dealership advised some clients are having to change tires 3000 t0 5000 miles of use. If this is not confirmation that tires being designated for this vehicle are not sufficient. 3 TIRES !!! within 2 months have blown, pothole and 3 tires within 2 monhts is not normal. How is mercedes allowed to place into the market a vehicle where its obvious there are no tires capable of handling its weight. After 2 incidents to leave vehcile undrivable, HOUSE rules no more EV. I would not feel comfortable my family this vehicle with tires which cannot sustain normal driving conditions.

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.

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.

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 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.
