Owner Complaints for the 2023 MERCEDES-BENZ EQS450

34 complaints have been filed with NHTSA for the 2023 MERCEDES-BENZ EQS450. Below is a breakdown by vehicle component.

Most Recent Complaints

I was stopped at a stop sign and when the light turn green I pressed the accelerator to move forward unfortunately, the vehicle hard braked for no reason. At first, I thought someone hit me from behind since there was no one in front of me but that was not the case. The braking was so violent that it caused my neck to snap back and forth, which caused the back of my head to hit the seat head support. I was going no faster then 10 mph but not slower then 5mph. In turn, the vehicle is available for inspection. My safety was at risk because I had no control or indicator that the braking was going to automatically brake on its own. The problem has not been reproduced or confirmed by the dealer or independent service center because the incident happened today (Sunday) therefore, I plan on making an appointment as soon as possible to see if they can identify any defects. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others since I plan on taking it to the Mercedes dealer where I purchased the vehicle. There were NO warning lamps, messages or other symptoms of the problem prior to failure.

The vehicle pre collision automatically stops the car completely five times with no car or any objects in the front. I took the car to Mercedes dealership to see if they can find the issues, but they can’t. On 04/07/2024 I had my wife record while I’m driving and we got video of the car just completely hard breaking on its own with no cars in the front. I am worry that another vehicle will rear end me at higher speed when it does happen again.

#11573091 | STRUCTURE:BODY | | N/A miles Crash
Please note that back in April 2023 my car was lawfully parked, and other SUV (Mercedes MB) was backing up and touch my front bumper. Because of that impact my front plastic grill got cracked and damaged front camera. The estimate to repair was almost $3000.00. I might assume it was a large impact, but yesterday during carwash when my car was not moving, car in front (another small SUV) suddenly rolled back and simple touched my front bumper. Because of that impact i got similar damage - front plastic grill is cracked and front camera is damaged. please note that other car didn't hit plastic grill as bumper is located further front. Its just of impact to front bumper to force front plastic to crack or poorly design of the components. I have both videos of impacts that i can provide upon request. I uploaded estimate from prior accident
