STEERING,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE — Filed 09/01/2024

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.

POWER TRAIN,ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM — Filed 04/15/2026

On April 15, 2026 at approximately 1:30 PM PT, I entered my 2023 Mercedes-Benz EQE SUV 500 4MATIC (approximately 20,000 miles) in my garage. The vehicle was not plugged in or charging prior to entry. I opened the car, sat in the driver's seat, and authenticated via the fingerprint scanner. The seat began adjusting to my stored profile position. While the seat was adjusting, I tapped the center console to open Apple CarPlay. The seat stopped moving midway through its adjustment, and what appeared to be every warning light on the instrument cluster illuminated simultaneously. I observed dozens of yellow and red warning icons, including a towing/recovery indicator. A number of warning messages also appeared on the screen. I manually adjusted the seat using the door-side controls. I attempted to shift into reverse to back out of the garage, but the vehicle would not engage. I then tried shifting into drive and the vehicle similarly would not engage. The drivetrain was completely unresponsive. I exited the vehicle, locked it, and re-entered to attempt a restart. All warning and system lights returned immediately and the vehicle again would not shift into any gear. I then connected the vehicle to my home charger. The charge port indicator on the vehicle flashed red, indicating it would not accept a charge. I disconnected the charger and attempted to start the vehicle a third time with the same result. I left the vehicle and took another car. The vehicle sat for approximately 45 minutes. At approximately 2:20 PM PT, another household member started the vehicle. It started normally with no warning lights and was able to drive without issue. The vehicle has been driven twice since this incident. On the following day (April 16, 2026), the Active Brake Assist system displayed a warning message indicating it is not functioning. This system was working normally prior to the April 15 incident.

POWER TRAIN,ELECTRICAL SYSTEM — Filed 03/14/2026

Vehicle shut down while driving on highway, repeated drive system malfunction, turtle mode. The vehicle has experienced a recurring, unresolved drivetrain malfunction — specifically, a drive system malfunction and battery malfunction causing the vehicle to enter severely reduced-power mode ("turtle mode") — that has persisted through a minimum of three (3) separate repair attempts across two authorized Mercedes-Benz dealerships, totaling more than sixteen (16) calendar days out of service within approximately 47 days of the first failure. Most critically, on March 14, 2026, while driving on a public highway in Ontario, Canada, this defect caused the vehicle to shut down completely while in motion, forcing me to pull over on the highway shoulder. The vehicle would not restart for approximately one hour. This constitutes a serious and dangerous safety hazard.

ELECTRICAL SYSTEM — Filed 10/03/2025

The vehicle has had repeated failures related to the air conditioning system and abnormal battery drain when the heating system is used. The vehicle has been taken to the dealership four times for the same issue and has spent more than two months in total at the dealership for repairs. The technicians have indicated that they have not been able to properly repair the problem. The vehicle continues to have unresolved defects affecting its normal operation and reliability. The vehicle has been at the dealer again from 3/26/2026 to present.

While driving down the highway late at night, with no other cars around, the panoramic sunroof exploded, throwing shattered glass everywhere. The window was not hit by an object and had no previous damage. Shattered flying glass while moving at highway speeds caused a momentary loss of control.

AIR BAGS,FORWARD COLLISION AVOIDANCE — Filed 01/19/2026

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.
