What 138 owners told NHTSA about the 2016 Mercedes-benz Glc-class Phev

I PURCHASED A BRAND NEW 2016 MERCEDES BENZ GLC300 IN DECEMBER OF 2015. OVER THE PAST 6 MONTHS, THE VEHICLE HAS BEGUN MAKING A TERRIBLE SCREECHING NOISE WHEN I LIGHTLY PRESS THE BRAKES WHILE IN REVERSE. THE NOISE HAS GOTTEN SO LOUD AND PAINFUL TO THE EAR THAT I REFLEXIVELY TAKE MY FOOT OF THE BRAKES CAUSING ME TO ROLL BACKWARDS FASTER THAN NECESSARY. I RECENTLY TOOK THE VEHICLE IN FOR ITS 10,000 MILE SERVICE DURING WHICH I INDICATED THAT THE CAR WAS MAKING A "SCREECHING" NOISE WHILE IN REVERSE WITH THE BRAKES APPLIED LIGHTLY ("FEATHERING"). I WAS TOLD BY THE SERVICE TECHNICIAN THAT MERCEDES WAS AWARE OF THE ISSUE AND WILL ISSUE GUIDANCE SOON. I WAS GIVEN MY VEHICLE BACK WITH NO TEMPORARY SOLUTION WHATSOEVER. SINCE OWNING THE VEHICLE (ABOUT A YEAR WITH 10,000 MILES), I HAVE RECEIVED NO COMMUNICATION FROM MERCEDES ABOUT THE ISSUE ALTHOUGH THEY HAVE BEEN AWARE OF THE "SCREECHING NOISE" FOR QUITE SOME TIME. I WOULD LIKE TO NOTE THAT THE SCREECHING NOISE IS GETTING SO BAD THAT IT IS TRULY PAINFUL TO ANYONE INSIDE THE VEHICLE (ALMOST AS IF I HAD NO BRAKE PADS!). I CALLED MERCEDES TODAY AND THEY AGAIN TOLD ME THAT THEY ARE AWARE OF THE ISSUE. I ASKED THE REP TO NOTE MY COMPLAINT AND ISSUE ME AN EMAIL CONFIRMING MY COMPLAINT FOR MY RECORDS - HE REFUSED. APPARENTLY MERCEDES DOES NOT PROVIDE EMAIL CONFIRMATION OF COMPLAINTS TO CUSTOMERS WHO HAVE ISSUES IN ORDER FOR THE INFORMATION "TO NOT GO PUBLIC." PLEASE SOMEONE AT NHTSA - LOOK INTO THIS. THEY NEED TO BE HELD ACCOUNTABLE. THANK YOU SO MUCH FOR YOUR TIME! *TR

I WAS STOPPED AT A RED LIGHT ON A MAJOR THREE LANE EACH DIRECTION HIGHWAY IN SUBURBAN IL, WHEN I STARTED TO GO AFTER THE LIGHT CHANGE THE CAR STUTTERED AND TURNED OFF. IT WAS RENDERED COMPLETELY INOPERABLE. THE CAR WOULD NOT SHIFT INTO NEUTRAL. THE RADIO AND WINDOWS WORKED, BUT NO OTHER ELECTRICAL COMPONENTS WORKED (E.G. DOOR LOCK/UNLOCK).

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

AT 7:30 AM ON JUNE 10, 2016, WHILE DRIVING NORTH ON RTE. 495 IN DELAWARE IN OUR 5-MONTH-OLD MB - GLC 300, THE PANORAMIC SUNROOF SUDDENLY AND WITHOUT ANY WARNING EXPLODED AND SHATTERED OUTWARD. THE SOUND WAS AS LOUD AS A BOMB. AS SHOWN IN THE PHOTOGRAPHS, NEARLY ALL THE SUNROOF WAS BLOWN OUT, WITH ONLY A LITTLE GLASS REMAINING AROUND THE FRAME. THE SHATTERED GLASS FRAGMENTS EITHER FLEW OFF OR SETTLED ON TOP OF THE SHADE SCREEN. WE WERE DRIVING AT APPROXIMATELY 65 MPH AND THERE WERE NO CARS DIRECTLY IN FRONT OF US OR BEHIND. WE HAD THE AIR CONDITIONING SYSTEM ON WITH THE OUTSIDE TEMPERATURE AT ABOUT 70F. IT WAS A CLEAR MORNING AND THE SUN HAD JUST RISEN. OUR MB DEALER IN GERMANTOWN, MD SAID THEY WERE NOT AWARE OF OTHER INSTANCES OF EXPLODING GLASS SUNROOFS

MESSAGE: DATE: 06/07/2016: RECENTLY, I PURCHASED A 2016 MERCEDES GLC300 AND WAS VERY UNHAPPY WITH THE FACT THAT THE ECO MODE IS THE DEFAULT AND IT HAS TO BE TURNED OFF MANUALLY EACH TIME YOU START THE ENGINE. I CALLED MERCEDES AND THEY SAID THERE IS NO WAY TO TURN IT OFF COMPLETELY. I BELIEVE THIS PRESENTS A HIGH RISK FOR STALLS THAT COULD POSSIBLY RESULT IN SEVERE BODILY HARM AND EVEN DEATH. WHEN THE CAR IS STOPPED THE ENGINE TURNS OFF AND WILL START IF ONE PRESSES THE GAS PEDAL. FOR EXAMPLE; WHEN TURNING LEFT AT AN INTERSECTION IT IS VERY UNCOMFORTABLE TO KNOW THAT THE ENGINE IS TURNED OFF AS YOU START TO PRESS THE GAS PEDAL--WHILE A LARGE TRUCK IS COMING VERY FAST. ONE JUST HOPES THAT THERE IS NO DELAY OR PAUSE WHEN YOU PRESS THE GAS PEDAL. I FIRMLY BELIEVE THAT THIS ECO ALWAYS ON (EXCEPT WHEN YOU REMEMBER TO PRESS A BUTTON TO TURN IT OFF) PRESENTS THE POTENTIAL FOR A VERY SERIOUS ACCIDENT. MERCEDES SHOULD PROVIDE AN OPTION THAT WILL ALLOW THIS ECO MODE TO BE SET TO ALWAYS OFF. THANK YOU!

I GOT MY BRAND NEW MERCEDES BENZ GLC 300 TWO WEEKS AGO. AFTER DRIVING FOR 6 DAYS & LESS THAN 300 MILES IN TOTAL THE SUV STOPPED RESPONDING ABRUPTLY IN THE MIDDLE OF HIGHWAY CRUISING AT A SPEED OF 70 MPH WITH A TRANSMISSION MALFUNCTION ERROR FLASHING. WITH NO POWER IN THE CAR, I WAS LUCKY ENOUGH TO PULL IT FROM THE LEFT MOST LANE TO THE RIGHT CURB BUT IT WAS EXTREMELY SCARY TO EXPERIENCE THE SITUATION OF AN IRRESPONSIVE CAR IN THE MIDDLE OF HIGHWAY WHILE THE CAR IS MOVING. ALL THE LIGHTS ON THE DIAL WERE LIT UP WITH A TRANSMISSION MALFUNCTION ERROR IN RED. TRIED TO SHUT OFF THE CAR USING THE ON/OFF PUSH BUTTON BUT IT DID NOT RESPOND. AFTER OPENING & CLOSING THE DRIVER SIDE DOOR, TRIED TO SHUT DOWN THE CAR AGAIN & THE ENGINE REVVED UP. IT WAS SURPRISING AS THINGS WERE ACTING OPPOSITE. I AM HAVING SAFETY CONCERNS WITH THIS NEW CAR, IF IT STOPS IN THE MIDDLE OF TRAFFIC AGAIN & IF WE WOULD BE LUCKY NEXT TIME TO PULL OVER SAFELY. THE SUV IS AT MY DEALERSHIP FOR THE LAST ONE WEEK. THEY HAVE CITED SOME FAULTY TRANSMISSION PARTS AS THE CAUSE OF THE PROBLEM.
