general problems of the 2013 Mercedes Benz ML350

Nhtsa vehicle safety complaint supporting statement vehicle: 2013 mercedes-benz Ml350 I am submitting this complaint regarding a continuing safety concern involving water intrusion and electronic system damage in my 2013 mercedes-benz Ml350. My vehicle was subject to a mercedes-benz recall involving water intrusion and related components. Despite recall-related repairs being performed, moisture and water intrusion concerns remain unresolved. During the diagnostic process, mercedes-benz personnel identified evidence of water and humidity in areas associated with vehicle electronics and control modules. The vehicle has experienced repeated mechanical and electronic issues following discovery of the water intrusion condition. Multiple repair facilities have been involved, and I have incurred significant diagnostic and repair expenses while attempting to determine the full extent of the damage. The primary concern is not ordinary wear and tear. The concern is that water intrusion has affected vehicle systems and that the recall remedy has not resulted in a complete resolution of the condition. I am concerned that moisture exposure may continue to impact vehicle electronics, control modules, sensors, and other safety-related systems. Mercedes-benz USA has been notified and a case has been opened. The dealership has also been involved. However, despite escalation requests and requests for management review, I have not received a meaningful resolution. The dealership continues directing me back to mercedes-benz USA while mercedes-benz USA has not provided a final management response. I respectfully request that NHTSA review whether the recall remedy adequately addressed the water intrusion condition and whether additional investigation is warranted regarding continuing moisture intrusion, electronic system exposure, and potential safety risks associated with this condition. I am prepared to provide repair orders, recall documentation, photographs, diagnostic findin.
