2023 Mercedes-Benz EQS Reliability Report

I am reporting a serious safety issue with my 2023 Mercedes-Benz EQS SUV. On multiple occasions, the vehicle has suddenly lost power and completely stopped while driving on the freeway without warning. During these incidents, a red warning symbol appeared on the dashboard (a red turtle icon), indicating a critical malfunction. These failures created extremely dangerous situations, as the vehicle lost the ability to maintain normal driving speed in active freeway traffic. At the time of these incidents, my three children were in the vehicle, which significantly increased the risk of a serious accident. This issue has occurred multiple times, suggesting a serious and recurring defect. The sudden loss of power combined with dashboard warning signals presents a major safety hazard and could lead to severe injury or fatal accidents. I no longer feel safe operating this vehicle and request that this issue be investigated as a potential safety defect.

I am submitting this complaint to raise a serious safety concern regarding the Mercedes-Benz EQS 580 SUV. This vehicle is sold and delivered without a spare tire and without run-flat tires. This design choice is dangerous and creates a foreseeable risk of severe harm to motorists. Recently, my wife and I — both senior citizens — suffered a tire failure in a remote area with no cellular service. Because the EQS 580 SUV was equipped with neither a spare nor run-flat tires, we were completely stranded. We were forced to walk miles to find a cell signal to call for help. This was a frightening and potentially life-threatening situation. It is entirely foreseeable that tire failure may occur in remote areas or where cell service is unavailable. A modern vehicle sold in the United States should not leave occupants with no means of mobility or self-rescue in such a situation. This issue poses a heightened danger particularly to: Senior citizens Families with small children Physically disabled individuals Anyone traveling in rural or emergency-prone environments A flat tire in these circumstances can result in individuals being stranded, exposed to the elements, injured, or worse. Someone could easily die in such a situation. In addition, Mercedes-Benz did not disclose at the point of sale that the vehicle lacks both a spare and run-flat tires. Had we been informed, we would not have purchased this vehicle. The manufacturer and dealer have a duty to warn consumers of a safety-critical limitation that eliminates an essential emergency capability. To my knowledge, it is unheard of — for a modern SUV, especially a premium vehicle marketed for safety and long-distance comfort, to be delivered without any means of addressing a tire failure. This is a serious consumer safety issue, and I respectfully urge NHTSA to investigate. A requirement for either a spare tire, run-flats, or clear disclosure at the point of sale is essential to protect the driving public.

Emergency braking system and violent seat belt retraction activated in error with no other vehicle in front of on my car . As I have vertigo and a pacemaker the seat belt retraction snapped my head forward in tightening my body but not my head resulting in severe head movement causing extreme dizziness. Also the rapid seat belt retraction place strong pressure on my pacemaker

I am writing to formally document and express serious concern regarding a lighting issue with my Mercedes-Benz EQS, which presents a significant safety hazard for both me and my family. Since December 2024, I have been facing a recurring problem with a dark shadow or image that appears while driving, particularly noticeable after dark. This shadow often resembles the shape of a person and unexpectedly enlarges or shifts, creating an alarming visual that demands immediate attention while driving. On numerous occasions, I have instinctively applied the brakes suddenly, believing that someone was standing in front of the vehicle, only to realize it was a visual distortion. This is not only disturbing but also dangerous, especially when driving at higher speeds or in traffic. Due to this ongoing issue, I have been unable to use the vehicle for commuting to work and have avoided driving it during family outings after dark. It has affected my daily routine, my family’s comfort, and our overall trust in the vehicle's safety. In the past few months, I have visited multiple authorized Mercedes-Benz dealerships—including San Jose, Stevens Creek, and Fremont—all of which confirmed the presence of the shadow issue. I have also shared the concern with a Mercedes Product Manager, and the email correspondence is attached for reference. Despite their acknowledgment of the issue, all parties have stated that this visual distortion is "as per design" and that they are unable to offer a solution. I was further informed that this issue exists across all Mercedes-Benz EQS vehicles, and therefore, nothing can be done. This is unacceptable. A known design flaw that causes visual confusion and repeated panic braking should not be dismissed. The fact that multiple dealers acknowledge the problem but claim it cannot be fixed raises serious questions about product safety and accountability. Mercedez is not helping at all This is a clear safety defect and needs to be addressed seriously.
