I RECEIVE WARNING AFTER I PASS 5 MPH SPEED IF ANY OF THE PASSENGER DOORS OR TRUNK IS OPEN. THE CAR NEEDS TO NOTIFY ME AS SOON AS IT GOES INTO DRIVE MODE. MANUFACTURERS RESPONSE HAS BEEN QUOTED BELOW. "WE TESTED A C300 HERE. IF THE DRIVER DOOR IS OPEN, THERE IS AN IMMEDIATE MESSAGE WHEN THE VEHICLE IS PUT IN GEAR (FORWARD OR REVERSE). HOWEVER, ALL OTHER DOORS RECEIVE A MESSAGE AT APPROXIMATELY 5 MPH. MERCEDES-BENZ RECOMMENDS THAT THE DRIVER MAKE SURE ALL PASSENGERS ARE IN SEATBELTS AND THE DOORS ARE SECURED. " *TR

## VIN PASSED ## MERCEDESCOLLISION AVOIDANCE DISENGAGED SCREEN POPPED UP, STOPPED VEHICLE AT STOP SIGN, THEN A DELAY IN ACCELERATION HAPPENED LEAVING US SUSPENDED IN THE MIDDLE OF THE ROAD WHERE WE WERE ALMOST HIT BY ANOTHER VEHICLE. GAS WOULD ONLY ENGAGE AFTER 10 SECOND DELAY AFTER I APPLIED CONSTANT PRESSURE. AT THE SAME TIME, THE IGNITION SWITCH IS NOT ENGAGING. I HAD TO PRESS THE START BUTTON FIVE TIMES TO FINALLY START THE VEHICLE ONCE I PULLED OVER AND TURNED OFF THE VEHICLE.

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.. *TR

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.
