The contact owns a 2024 Mercedes-Benz EQE 350+. The contact stated that while her husband was driving at 75 MPH, the panoramic sunroof suddenly shattered without warning, producing a loud booming sound. The contact's husband pulled over and inspected the vehicle before driving back to the residence. There were no other vehicles or objects nearby to cause external impact. The vehicle was taken to a dealer, where a repair estimate was provided. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 37,000.

Component/system that malfunctioned: The braking and acceleration system, including the collision assistance (driver-assistance/automatic braking) feature. The vehicle is available for inspection upon request. How safety was put at risk: The car lags when braking and at times accelerates unexpectedly. On one occasion, the collision assistance system—which is designed to brake—instead caused the vehicle to accelerate. The most dangerous incident occurred when the car accelerated on its own into an intersection, nearly causing a collision. Reproduced/confirmed by a dealer or service center: The vehicle was taken to the Mercedes-Benz dealer twice regarding this issue. On both visits, the dealer reported that they found no problem. The fault has not been confirmed or reproduced by the dealer. Inspected by manufacturer, police, insurance or others: Inspected by the Mercedes-Benz dealer on two occasions (no fault found). UNKNOWN whether the manufacturer's engineering team, police, or insurance representatives have inspected the vehicle—to my knowledge, they have not. Warning lamps, messages, or symptoms prior to failure: UNKNOWN / none noticed. No warning lamps or dashboard messages were observed before or during these events. The symptoms (braking lag and unexpected acceleration) have been consistently noticed by all three drivers of the vehicle.

The vehicle experienced repeated electrical wiring harness damage in the lighting, tire and connector areas due to exposed and insufficiently protected wiring near socket terminations. On two separate service visits, authorized dealership technicians confirmed that rodents chewed through multiple exposed wires. The affected wiring involves critical electrical systems. The connectors lack adequate shielding, loom, or protective insulation at exposed termination points. The insulation ends before the connector, leaving conductors vulnerable to environmental exposure and rodent access. Warning indicators illuminated on the dashboard, and the vehicle required dealer repair on both occasions. The damaged wiring was inspected and confirmed by certified technicians and is available for inspection upon request. This condition presents a significant safety risk. If a rodent partially damages a wire connected to braking systems, steering systems, high-voltage components, sensors, or engine control systems, failure could occur while the vehicle is in motion. A sudden loss of power, interruption of propulsion, or malfunction of safety systems at highway speeds could increase the risk of a crash. Because this is an electric vehicle, sudden electrical interruption may result in complete loss of propulsion or charging capability. If such failure occurs in remote areas, at night, or in extreme weather conditions, occupants could be left stranded in potentially hazardous situations. This issue has occurred more than once, and no permanent preventive solution has been provided. The design appears to leave critical wiring insufficiently protected from foreseeable environmental and rodent exposure, creating an ongoing safety hazard. I request review of whether the wiring design provides adequate protection for safety-related electrical systems.

Twice, the car has autonomously braked when there was no threat to the car. The first time we were subsequently rear ended, though fortunately at low speed. There was cosmetic damage to the bumpers of both cars and the occupants were shaken up, but not injured. The second time the were driving at about 35mph when the car slammed on the brakes. Fortunately the following vehicle was not close and there was no collision. The occupants were again shaken up, but not injured. The "braking assistance" can be disabled, but only for the current trip. It is automatically reenabled the next time the car is started.

On [XXX] around [XXX] while driving my 2024 Mercedes-Benz EQE350 [XXX] near Santa Clarita, CA, I experienced a flat tire due to a 4 mm puncture in the center tread of the rear driver's side tire. I immediately contacted Mercedes Me customer support , and the representative advised me that my vehicle's run-flat tire system would allow me to continue driving up to 50 miles, as long as I stayed under 50 mph. I followed this guidance very cautiously, driving under 30 mph. Despite this, the tire completely blew out in less than10 miles. The road conditions were normal, the tire was in good condition prior to the incident, and weather was mild. This incident endangered my safety and that of my wife and our toddler, who were in the vehicle with me at the time and was extremely frightened by the sudden blowout. I believe the run-flat system failed to perform as expected and/or the advice I received from Mercedes Me was unsafe and caused more damage to my vehicle and put my family in more danger. I am submitting this report in case other Mercedes EQE owners experience similar failures. I request that the federal safety agency investigate whether this represents a design flaw or safety hazard in the vehicle's tire/run-flat system?
