2023 Mercedes-Benz E-Class Reliability Report

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.

I am submitting this complaint regarding serious and repeated electronic failures in my 2023 Mercedes-Benz E 450 that pose a significant safety risk to myself and other drivers on the road. The vehicle has experienced complete dashboard failures on multiple occasions, including the loss of speedometer, fuel gauge, and gear shift indicators. Most critically, the vehicle recently shut down while in motion, displaying a “malfunction” warning and disabling the electronic steering system. I was unable to maneuver the vehicle off the road, creating an extremely dangerous situation. This vehicle has been brought to the dealership three or more times for the same issue, with no permanent resolution. I believe this constitutes a serious safety defect. I respectfully request that the NHTSA investigate this matter as a potential recall issue.

My vehicle is equipped with a camera system which, when in reverse gear, displays objects/people behind the vehicle and, when going forward to park, displays objects/vehicles ahead. For the first 11 months of ownership, the system has worked properly. For the last 6 months the system has worked intermittently. The vehicle, purchased new, is under warranty and has been returned to the dealership 4 times for software updates and and part replacements. Two weeks after the last visit, the camera system was inoperative again. Shortly after I returned home and went out again the camera system worked properly. Several years ago, Mercedes recalled 347,000 vehicles for a similar problem. My vehicle was purchased after the recall and did not fall into the category of vehicles that were recalled but it seems that, with the Mercedes brand, the problem still persists. To the extent the camera system will alert you to the presence of a person when backing up, this is a safety issue which needs to be addressed. Thank you

The fuel pump on my vehicle failed multiple times, including coming off start / stop at traffic lights, as well as when being started. When at a stop light turning from red to green, my car did not respond, putting me in danger of being hit from behind. The vehicle is being repaired under warranty at a manufacturer dealership. It appears this is a known issue under NHTSA recall 23V445000, although my vehicle is not currently included in the recall after a VIN search of the NHTSA check for recalls page. My vehicle exhibited the same signs as others affected by this recall, including flashing "malfunction" when it occurred.
