2023 Mercedes-Benz E350

While driving the vehicle in normal road conditions the car suddenly stop and activated the seat belts. This incidents has happened 4 times. The vehicle has been taken to the Mercedez-Benz service and it gas been released with no findings. I am concerned with this safety issue on my leased vehicle and the risk to cause a collision or injury. The last incident occurred on 3/8/2026, while driving the car.

I am a small auto repair shop, in Houston, Texas. The driver's (left) side rear brake caliper bracket appears to be defective. The car came in with the mental to metal break wear on the driver's side, while the passenger's side brake pads still at 50% life. The break wear sensor didn't trigger the light, because there is only one sensor on the passenger side. Upon further investigation found that the inner brake pad was catching on the caliper bracket. Same was true for the new brake pad set as well. Fault appears to be in the caliper bracket. This could be a designed flaw by the manufacture., if so, it is your responsibility to get them.

This is the second report filing about the trunk lid closing without initiating the automatic closure. In order to keep this record accurate, the vehicle was brought into the Mercedes Benz dealer, (where it was purchased), on May 23, 2023. The service advisor came to the car to instruct me on how to use the mechanism. He was unable to operate it correctly either. The car was also brought in for other needed repairs. When the car was returned to me on May30th, this same service advisor reported to me that the dealership was unable to correct the problem with the trunk lid mechanism. On June 12, when I was retrieving some items from my trunk, NOT using the automatic mechanism, the trunk lid unexpectedly crashed down and struck me in the head. I experienced headache and bruise on the back of my head. The salesman and administrative team at the dealership said they declined to return my phone calls, or speak directly with me about this matter, due to fear of being sued.

May 4, 2023 at approximately 5:45 PM, while reaching into the trunk of my car, the trunk lid came crashing down on me. To avoid being struck on the head, I blocked it with me left forearm. The trunk lid caused a large nasty and painful wound. I immediately texted my sales person, and text him a picture of my injury. I also left a voicemail message for him at the dealership. Unfortunately, this is not the first time the issue with the truck lid has happened to me. On another occasion, while reaching into the trunk, I was able to avoid being struck by the trunk lid, when it unexpectedly came crashing down. At approximately 8:50 AM, on May 5, 2023, a follow-up call was made to the dealership since my salesman did not return my call. The male who I spoke to about this serious safety issue assured me that I would receive a return call the same day and listed three male supervisors by name. Since I did not receive this promised return call, I made an appointment with the service department to document this dangerous issue. OF NOTE: my feet were not under the rear pumper to activate the trunk lid, and the obstacle feature failed to stop the lid from crashing down.
