My vehicle, a 2015 Mercedes-Benz C300 purchased on 6/6/15 with approximately 1200 miles on the odometer. On Monday morning 7/20/15, at approximately 5:30 am pdt, I was driving on the freeway when the interior lights came on and the drivers door popped open. There was no warning chime or indicator light prior to this happening. It was very frightening, and caught me by surprise. Luckily at the time there were no other cars near me. I was able to slow down and shut the door. I called the dealer and they were concerned and had me drop it off that afternoon. Picked up on Tuesday afternoon 7/21/15 approximately 5:30 pm pdt. I was told they couldn't duplicate the door opening. However, looking at forums on the internet, this exact issue has been reported by others in the us and australia at least. Some were the drivers door others were the passengers door. One reported it happening a second time after the dealer inspected. I am very concerned about this happening again, and possibly triggering an air bag or auto-park. I do not feel safe in this car. I have contacted Mercedes-Benz usa via chat this morning 7/22/15 and they will have a case manager contact me.

Soon after purchasing Mercedes, discovered the following potentially hazardous safety issues (all of these features are standard): 1) new "keyless-go locking system is factory programmed to unlock all doors when key is in owner's possession & rear driver's door handle is touched, allowing intruder(s) to easily enter other side of vehicle. 2) new command/computer/touch pad system, controls various operational functions, like radio, encouraging driver to take eyes off the road to operate. Touchpad requires driver to make "mouse-like" actions on computer pad (located on console) while simultaneously driving. 3) new air flow & vent system, circulates air from grill to windshield, allowing leaves & other debris, incl. Water, to enter engine compartment at the top of hood. Debris lodged here could potentially result in overheating & cause fire or result in damage to wiring and/or other components of the engine. 4) letters (w/pictures) sent to mbusa, CEO, resulted in phone calls from subordinate staff, rejecting outright each complaint but advising that debris in engine area is "normal" & customer's responsibility to remove. Letter to daimler's CEO in germany was referred back to mbusa. 5) asking for your intervention before these problems potentially result in injury or fatality. If this is not the office to investigate & intervene, please forward to the correct Agency & advise accordingly. Can provide additional info. On request. Thank you...
