4 Battery Dead problem of the 2015 Mercedes Benz C300

Failure Date: 02/05/2015

On 11/1/14 I filed a complaint about safety issues with my new 2015 mercedes, C300 (odi # 10664470) that pertained to debris entering the engine compartment from the top, near the windshield, and other issues with the command "radio", "touch pad" & keyless entry locking systems. I understand these systems are not proprietary to mercedes and so are in many other luxury models. I've rec'd no feedback from the daimler corp or from your office. Now a new issue developed where the keyless go wouldn't allow me to either enter the vehicle or sound the "panic" alarm. The company doesn't know how or why this could happen or how to fix it. I'm especially concerned with the inability to use the panic button, which is there in case of a criminal or medical emergency. What a surprise when you go for it and it doesn't work. There is no back up should the battery fail to work. I believe this is another safety issue with this car and would appreciate it if your office would take me seriously and contact me before someone is injured or killed. . Thank you. .

5 Battery Dead problem of the 2009 Mercedes Benz C300

Failure Date: 04/05/2011

I bought my Mercedes Benz and notice that my tail light and the light on the front of the car will turn on by itself while my car was parked in the morning my car battery will be dead needing a charge. I had a recall from Mercedes Benz dealer and I took the car to the dealership and supposedly they fix it and the car had gotten worse. It had burned the harnesses and fog harness, while I was driving the car was acting like shutting off the radio and ac will start shutting off and turning on at the same time while I was on the highway on my way home from work. Right now my car only have working the high beam. I been getting a lot of recalls for this car but really it seems like I'm loosing my time .
