2023 MERCEDES-BENZ Eqe 350+

My Mercedes-Benz EQE has an intermittent but dangerous brake failure. When braking lightly and then needing to brake harder, the brake pedal becomes soft and fades, sinking further with almost no increase in braking power. The vehicle continues moving forward even when pressing the pedal harder. I must quickly release the pedal and press it again to regain braking. This creates a serious risk of crashing, especially at low speeds or in traffic. The issue is happening more frequently. Mercedes-Benz of Encino told me “everything is good,” but the issue continues. Another dealership (Mercedes Keys European) refused to even inspect the vehicle. A loaner EQE I drove for several days did NOT have this issue, confirming my vehicle’s braking system is not normal. This is a major safety defect, and I am requesting NHTSA to investigate.

September 8th, 2024 @ approximately 3pm My Mercedes EQE 350+ accelerated to a high speed when the front tire touched a curb. The car ran over the curb and into the parking lot. I was able to steer the car but the brakes didn't work. The car kept going through a stop sign and into the intersection. Luckily there were no cars in the intersection and I finally thought to turn the car off. It then stopped. The whole rubber covering over the battery was destroyed from the rocks on the curb. The battery was severely damaged also. The car was at the dealership from Friday Sept 13th until around Oct 9th. They finished their testing and sent the info to corporate Mercedes on Wed Sept. 18th. I finally heard back from Mercedes corporate on Oct 3rd, 2024. They said that they didn't find any malfunctions. During this waiting period I was pressured by the Mercedes dealership to file an Insurance Claim. I said I wasn't filing a claim until I heard back from Mercedes Corporate. There have been several cases online where the same issue has occurred by other Mercedes owners. One was almost exactly the same as mine. The only difference was that the car stopped when the tires were flattened. I have been driving for 50 years and have never experienced anything like this. My nephew was in the car with me and I repeatedly said to him the brakes aren't working. The car was a write off. I had to file an insurance claim.
