HI I CURRENTLY OWN 2015 ML 350 BLUETEC, WAS DRIVING THE ML AND ALL OF SUDDEN THE PANORAMIC ROOF SHATTERED WITH GLASS PIECES RAINING LUCKILY MY KIDS WEREN'T IN THE CAR AND I WAS BY MYSELF. I HAVE DONE SOME RESEARCH ONLINE AND HAVE COME ACROSS THAT THIS IS A COMMON PROBLEM IN THE ABOVE MENTIONED MODEL. PLEASE ADVISE ME IF THERE IS A RECALL OR IF THE ROOF REPAIR IS COVERED BY MERCEDES. SINCERELY [XXX] THE ABOVE MESSAGE WAS SENT TO MERCEDES AND THEY CONTACTED ME BACK TODAY THAT THEY WILL NOT COVER THE FIX AND THEY ARE AWARE OF THE PROBLEM. I WOULD RECOMMEND IF THEY ARE FULLY AWARE OF THE GLASS SHATTERING THEN THERE SHOULD BE A RECALL OUT TO REPLACE THE GLASS WITH LAMINATED ONE, IF IT SHATTERS IT DOESN'T INJURE ANYONE SITTING INSIDE. IT WAS A SUNNY DAY NO RAIN AND I WAS DRIVING THE VEHICLE ON A STRAIGHT ROAD AT 50 KM PER HOUR. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

"PRE SAFE FUNCTIONS LIMITED" MESSAGE APPEARED ON DASHBOARD IN NOV '16. OVER COUPLE MONTHS, AUDITORY BEEP WARNING OF BEING TOO CLOSE TO SOMETHING HAPPENED WITH NO HAZARD NEARBY APPROX 6 TIMES. ON 4/2/17, WHILE DRIVING 35 MPH ON SUNNY DAY, AUDITORY WARNING STARTED (WITH NO HAZARD NEARBY) THEN STOPPED WHEN WE STOPPED AT TRAFFIC LIGHT. BEEPING STARTED AGAIN (WITH NO HAZARD NEARBY) WHEN WE STARTED DRIVING, THEN CAR SELF-BRAKED WHILE DRIVING AT LEAST 20 MPH AND CARS AROUND US STARTED HONKING. STARTED DRIVING AGAIN AND CAR SELF-BRAKED AGAIN. WE PULLED INTO A PARKING LOT AND TURNED OFF THE CAR FOR A FEW MINUTES, CALLED CAR DEALER. SENSORS IN FRONT DID NOT APPEAR DIRTY OR BLOCKED BY ANYTHING. WE WERE ABLE TO DRIVE HOME 10 MIN WITHOUT INCIDENT. NEXT DAY, CAR DEALER REPORTED IT WAS A COMPUTER ISSUE THAT THEY FIXED BY UPDATING SOFTWARE. PAPERWORK READS "PERFORMED REPAIR AS PER BULLETIN." ON 4/4/17, "PRE SAFE FUNCTIONS LIMITED" WARNING APPEARED AGAIN.

THE VEHICLE WAS IN REVERSE WHEN A STRONG SOUND WAS HEARD COMING FROM THE BACK, AFTER STARTING THE CAR, IT DISPLAYS A WARNING MESSAGE LIGHT ON THE DASH; IT BECAME DIFFICULT TO MANEUVER AND A SQUEALING SOUND WAS HEARD COMING FROM THE ENGINE, THIS COULD EASILY HAVE RESULTED IN A LOSS OF CONTROL AND A CRASH WITHOUT ANY WARNING. IMMEDIATELY MBRACE WAS CONTACTED AND THE VEHICLE WAS TOWED AND TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE POWER STEERING CONTROL FAILED AND NEEDED TO BE REPLACED WITHOUT WARRANTY AND AT MY OWN COST. THEY ACCUSED ME THAT THE CAR MUST BE INVOLVED IN AN INCIDENT/ACCIDENT, BUT IT IS TOTALLY IMPOSSIBLE FOR THE CAR TO HAVE SUFFERED A HEAVY BLOW, OR TO HAVE GONE INTO A HOLE, OR TO CLIMB A HIGH SIDEWALK, ETC. WITHOUT A SIGN OF DAMAGE; THE DAMAGE PIECE (STEERING GEAR) IS LOCATED IN A PLACE THAT WOULD BE TOTALLY IMPOSSIBLE TO REACH WITHOUT THE CAR SUFFERING A HEAVY IMPACT, WHICH WOULD HAVE CAUSED AN ADDITIONAL EXTERNAL DAMAGE BELOW, OR IN THE TIRE, BUMPER, RIM, OR ANY OTHER PART, EVEN THE AIR BAGS. THE CAR EXTERNALLY INCLUDING EACH SINGLE PART, IS IN PERFECT CONDITION. THIS DAMAGE WAS NOT CAUSED BY ANYTHING THAT I DID WRONG; MUST BE A DEFECTIVE PART FROM THE MANUFACTURE, AND I CAN'T NOT ASSUME RESPONSIBILITY OF THIS. THE MB USA WAS MADE AWARE OF THE FAILURE, AND THEY INSIST THAT I HAVE TO PAY FOR IT OR MY CAR INSURANCE NEEDS TO BE RESPONSIBLE MONETARILY OF THIS SITUATION, WHICH IS COMPLETELY UNFAIR TO ME AND SHOULD BE COVERED BY THE WARRANTY. IT HAS ONLY 18,000 MILES APPROX. AND I SHOULDN'T HAVE SUCH A SERIOUS PROBLEM WITH THIS BRAND AT SUCH LOW MILEAGE. IF A DEFECTIVE DRIVING PART IN THE STEERING GEAR EXISTS IN THE VEHICLE, THAT CAUSES IT TO BREAK DURING NORMAL VEHICLE TURNING, THE NORMALLY AVAILABLE HYDRAULIC SUPPORT FUNCTION WILL NO LONGER FUNCTION AND STEERING WHEEL OPERATION WILL BE LIMITED. *TR
