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 2022â2024 EQS-platform vehicles and…

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.

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…

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…
