Chronology of Events [XXX] (Purchase & Test Drive): I purchased the vehicle as a Certified Pre-Owned unit from Mercedes-Benz of North Houston. During the initial test drive, I explicitly noted and pointed out an active issue with the radar/sensor system to the sales team.

Severe, life-threatening autonomous safety system and powertrain failures in a 2023 Mercedes-Benz EQE SUV. The vehicle exhibits sudden, violent unintended acceleration, unprovoked emergency braking, and steering lockups. On multiple occasions, including at 75 MPH on the freeway and 45 MPH on city streets, the vehicle abruptly applies maximum braking force down to a near-stop without driver input or any road obstruction, nearly causing multiple catastrophic rear-end collisions with semi-trucks and buses. Conversely, the vehicle experiences sudden unintended acceleration; during one severe city street incident, the vehicle unexpectedly accelerated from 40 MPH to 60 MPH while the driver was actively braking, causing the brake pedal to feel completely locked, stiff, and unresponsive for several seconds before stopping. While stopped at red lights, the vehicle violently surges and rocks forward/backward as if wanting to accelerate without driver input. The steering assistance system abruptly locks up or pulls hard to the right without warning, requiring the driver to physically wrestle control to maintain lane alignment. The braking system suffers from severe malfunctions, including the pedal randomly repositioning itself lower while driving and dropping completely to the floor during parking, causing the vehicle to roll until pumped. The electronic parking brake intermittently fails to release when shifting into drive/reverse. Additional systemic electrical and safety defects include: complete instrument cluster/gauge blackouts impairing speed monitoring; steering wheel physically blocking gauge visibility; total failure of rearview/surround-view cameras, blind spot monitors, and mirror controls; exterior door handles failing to deploy; rear trunk malfunctions; severe high-voltage battery range loss; and continuous infotainment/navigation crashes. Authorized dealerships have failed to repair these critical safety components across 4 distinct repair attempts.

Description of Incident: On January 19, 2026, this vehicle was involved in a severe frontal collision. Despite significant structural damage resulting in a total loss (GEICO Claim: 0445628610101151), multiple critical safety systems failed to activate. Specific System Failures: SRS (Airbags): None of the 10 airbags deployed despite a high-energy impact that met deployment thresholds. Active Brake Assist: The system failed to monitor traffic or apply autonomous braking to reduce impact severity. Steering/Stability Assist: No steering intervention or collision warnings were provided during the pre-crash phase. GUARD 360: Collision detection monitoring failed to log the event. Safety Risk: The failure of the airbags to deploy during a high-energy impact represents a catastrophic failure of safety systems mandated by FMVSS 208 and directly increased the risk of occupant injury. Warning Symptoms: The dashboard was clear of all safety faults. No SRS or restraint system warning lights were present prior to the incident. Inspection Status: As of January 22, 2026, the vehicle is being held at Mercedes-Benz of Stevens Creek (San Jose, CA). It is awaiting a formal technical inspection from Mercedes-Benz Corporate. The vehicle is available for NHTSA inspection.

On several occasions the vehicle aggressively stopped and jerked as if someone hit my car from behind. I took it to the dealership and they thought it was a software malfunction issue, since there were recalls on the vehicle. I received my car back from the dealership and in a week of receiving my car, the issue happened twice. This has been extremely scary especially because on two occasions a car almost hit me in the back and both times my son was in the car. The car has done this where there were not any cars around and the car falsely believes there is a car around a collision will occur. Today , the car did it twice. The first was while I was taking my son to school going slowly. The second time this happened was while I was stopped at a red light. The dashboard then had a red triangle with an exclamation mark inside. Every time the car stops it caused my neck and back to hurt and I am afraid a car will actually hit me from behind.

On Mon, [XXX], my father was involved in a single car accident in the family's Mercedes-Bens EQE 350 (all electric) vehicle. When he was in driveway, he claims he was on the brake when the car suddenly accelerated on its own. It destroyed the garage door and then went through the garage destroying property, the attic staircase, and the frame of an interior wall into a bedroom. We have pictures of the damage. Emergency repairs were required to stabilize the frame of the house with more 2x4s. The insurance company says he likely confused the brake and gas pedals, but he's convinced that he was on the brake when it suddenly accelerated on its own. Importantly, no auto-emergency braking occurred, no airbag deployed, and no other emergency systems engaged. We received no indication that the system reported an accident. I was able to source an online forum where individuals recounted identical fact patterns about being on the brake and the Mercedes EQ vehicle accelerating dangerously on its own. We believe that the issue was a electrical computer malfunction and yes, the car is available for inspection. It is currently being repaired at a collision shop in Edison, NJ. I have sent a general service request to Mercedes Benz to encourage an inspection from them. The problem has not yet been sourced or reproduced and no warning lamps or messages appeared prior, during, or after the accident. Here's the MB electric vehicle community message board describing similar accounts [XXX] I am messaging to initiate a safety report about this vehicle since this issue could potentially cause a fatality if not properly addressed.

There have been 3 instances of the same incident of the Automatic Emergency Breaking system failing, the 3 times has happened over the 8 months I have owned the car. Mercedes has aknowledged the failure of the automatic breaking system but they do not have any fixes for it. When I am driving, if the safety system senses a police radar system a car may have installed (like an old school one on a civilian's car dashboard) the car's security system "shuts down" for a couple seconds and slams on the breaks nearly causing a crash. I have been driving at 15-20 MPH on a clear street and out of nowhere the car slams on the breaks because it detects someone's radar detector. As you can imagine, this is absolutley terrifying to be driving on a clear street and have the car slam on it's breaks. My heart rate goes up, I have been visibly shaken up. The feeling is as if I got into a car accident-but I didn't it was self-induced by the vehicle. I am worried if someone is driving behind me and is not prepared for the car to break, I will be rear-ended. Please help Mercedes owners fix this, it's horrible.
