While driving my 2026 Mercedes-Benz E350 (rear-wheel drive) at approximately 40 mph, I began slowing for a traffic light. As I approached the intersection, the vehicle suddenly experienced what appeared to be a catastrophic electronic failure. Without warning, the vehicle became almost completely inoperable while the engine continued to run. The vehicle abruptly came to a stop and became immobilized. The rear wheels locked, preventing the vehicle from moving. I was unable to shift the transmission out of Drive or into any other gear. The gear selector became completely unresponsive. I was unable to shut the vehicle off. Numerous warning lights and system malfunction messages appeared simultaneously across the instrument cluster. The windshield wipers activated on their own without any driver input. The windows rolled down automatically and would not roll up. Nearly every electronic system appeared to malfunction at the same time. I lost the ability to control the vehicle normally because I could not shift gears, restart the vehicle, or clear any of the system failures. The engine continued running throughout the event, but the vehicle was effectively disabled and could not be driven. Emergency personnel were dispatched to guide the flow of traffic as the vehicle was obstructing traffic. This failure created an extremely dangerous traffic situation. The vehicle became immobilized in the roadway without warning during normal driving. As the driver I had no reasonable ability to anticipate or respond to this type of sudden total electronic failure. The vehicle has 1,117 miles. Unlike other reports to the NHTSA, this was not an isolated warning light or infotainment issue. The simultaneous failure of multiple independent systems suggests a significant electrical, software, communications network, or control module malfunction. The vehicle is currently with the dealership, they have been unable to diagnose the problem as the vehicle remains unresponsive.

Mercedes-Benz E350 Mild Hybrid was purchased new on XXX. Vehicle had approximately 291 miles and had been owned 25 days, when incident occurred on XXX at approximately 9:30am. Incident occurred during normal interstate driving (I-10 between [XXX] and [XXX]) at approximately the posted speed limit of 60mph. Weather was partly cloudy, not raining. A sudden loud explosive sound occurred, similar to a gunshot. There were no warning lamps, messages, or other symptoms prior to the explosive sound. Neither of 2 occupants in vehicle observed an object strike the vehicle. Sunroof was completely closed at time of incident. Passenger opened inside cover of sun roof and immediately observed shattered panoramic roof glass, with almost half of the sunroof gone. Remainder of sunroof was cracked into very small fragments. Glass appeared to largely disperse outward; interior sunshade prevented glass from entering the passenger compartment, although there were shards of glass lying within the sunshade. Vehicle was safely removed from traffic. No injuries occurred. But half of glass from sunroof was scattered toward other lanes of busy interstate traffic. Passenger safety could've been compromised had the glass torn the soft fabric sunshade. Passenger safety could've been compromised if driver had been distracted by the explosive sound. Glass could've been safety hazard for other vehicles behind mine. Mercedes-Benz denied warranty coverage and refused to provide owner a written engineering explanation of the cause of the accident. Mercedes-Benz field technical rep and dealer service department reviewed the car's damages. Vehicle has since been repaired at owner's expense. Owner has photos of damaged roof prior to repair. Owner plans to sell vehicle on or about XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. Car's computer abruptly shutdown all controls/systems when lightly applying brake to stop at yellow light. Lost Total control of car, steering locked, 4 wheel drive locked all wheels, park brake inoperable, doors locked, windows would not operate, key fob was made inoperable, HVAC was inoperable, no lights worked except for Emerg flashers, wipers activated and went erratic, multiple alarms went off saying what Not to do but gave No advice on "What to do", MB SOS made inoperable. see MB Inv 379224 they determined it was EZS control module. BUT MB gave no diagnostics why the car left driver with control of nothing. 2. My safety was put at high risk. Why? I manually opened driver door, it closed itself car on a slight inclined Rd, manually opened trunk to warn others, returned to car and all doors are locked, plus all retractable handles flush with door body manual key useless. Due to perfect weather day, passenger window down 3in allowing to insert arm to unlatch door manually. Car was in lane 2 of 3 lane traffic light intersection. Very busy major road accessing a 6 lane US Hwy. Luckily Police arrived on their way to work, stressed very dangerous location, stayed until car towed away. 3. MB dealer returned car. Will not confirm they will do a root-cause analysis of the total loss of control when one item (EZS) fails and leaves driver totally unsafe. There must be a software malfunction.....too many alarms. MB cannot assure this E350 or (any other one) will not have this type of shutdown again leaving the driver Unsafe. Reading MB car safety policy this dealer and MB USA Georgia do not comply with the policy. Concerns over Driver safety remain very high despite the replaced EZS, software was not diagnosed 4. Dealer stated on Jun 26, the failed EZS is yet to be analyzed and gave no timeline to do so. I gave 26 days for dealer to comply with MB policy. It is not forthcoming 5. Absolutely No warning lamps, alarms or any operational symptoms prior to total shutdown

I wish to respectfully report a safety concern with my new 2026 Mercedes All-Terrain Wagon. Specifically, at certain sun angles under cloudless skies, flaring occurs on the inside of my front windshield. They would appear to be linked to the Heads-Up Display Unit via reflection. The housing and dash can also reflect patterns on the windshield. Again, this occurs under certain sun angles when the sun is anywhere between 11 o'clock and 4 o’clock. Additionally, the density of a flaring pattern can be dense enough to obscure signs, objects, or other hazards. For this reason, I strongly believe this constitutes a safety hazard as well as something that plagues automobile travel: principally distractions. I do agree that flaring on a small level can occur in connection with HUD’s. Nevertheless, on this vehicle, I contend it is excessive and usually appears every day under bright sun conditions. In shade or cloudy conditions, this is not an issue. This was first noticed sometime after 500 miles in winter, under sunny conditions. I now have 10,500 miles with no resolution from Mercedes national. After documenting this case from the beginning, I was notified today, 06/25/26 by the Service Manager at Chico, California, Mercedes, that the national engineers determined this was normal. In fact, one of these engineers came to Chico to inspect my vehicle. Respectfully, I beg to differ and ask you to open a case to investigate further whether this is an anomaly that constitutes a safety concern and/or a distracting issue, which is another threat to safety. For further information, contact Mercedes Benz of Chico Service 530-345-9444. I wish to add credibility to this case, as I am a retired airline captain with 26,000 hours of flying time, including 10,500 hours on the Boeing 777. You can understand my emphasis on safety: anything that impairs visibility and distracts, in my view, is a red flag. I certainly appreciate the work all of you do, with thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
