There are several issue with the 2024 Mercedes EQS. I had the car have a full system failure and stop in the middle of the road with no warning. It could not even be towed. Apparently coolant was leaking without any warning. This caused a complete system failure- car wouldn't power on, couldn't be towed, couldn't be pushed to a safe location- nothing. The next most concerning issue is car automatically locks itself within seconds and with the key inside and with a passenger inside. My baby was trapped in the car. I came out of the driver seat and the key was in my purse. This could've resulted in a fatal incident. I live in [XXX] where we have a lot of heat. What if my key and phone were both in the car and my daughter was trapped. The car has locked automatically with key still in the car on multiple occasions. The car shuts off on its own within 2 minutes while passengers are inside. Again, as a parent this is deeply concerning and can lead to a fatal incident and overheating The lane correction is extremely harsh and many times wrong pulling the car in the wrong direction and with a lot of force INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The electric refrigerant compressor on my 2023 Mercedes-Benz EQS 580 4MATIC SUV failed without warning. On this vehicle, the compressor is a dual-function safety-critical component: it provides cabin air conditioning and, more importantly, active cooling for the high-voltage lithium-ion battery pack. I am filing this complaint because a single-point failure in a component responsible for high-voltage battery cooling should not occur on a vehicle of this age and mileage, and because owners receive inadequate warning of the safety consequences when it does. I request that NHTSA investigate the failure rate of the electric refrigerant compressor on 2022–2024 EQS-platform vehicles and evaluate whether the battery thermal management design provides adequate redundancy and driver warning The vehicle was taken to an authorized Mercedes-Benz dealer, which confirmed the refrigerant compressor failure and replacing the compressor under warranty. Parts are backordered per Mercedes. The vehicle has been off the road for 28 days The dealer did indicate awareness of similar failures on other EQS vehicles.

during car drive on freeway 202 from Queen Creek to Scottsdale in Arizona on 01/03/2026, estimate speed 65 mph, my sunroof was blowup and totally broken on many small glasses w/out any reasons.

My Mercedes EQS SUV has experienced repeated safety-related defects. The brakes have intermittently locked up while driving, creating a serious safety concern. The vehicle also vibrates at highway speeds on the freeway. These issues have occurred on two separate occasions. Despite multiple service visits, the dealership has been unable to diagnose or repair the problems. During the first incident, they reset the software. During the most recent incident, multiple software error warnings appeared simultaneously, indicating system malfunctions (see images for documentation). The vehicle has now been at the Mercedes service center for over two weeks, with required parts on backorder from Mercedes and no estimated repair timeline provided.

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.
