2016 Mercedes-Benz GLC-Class Brakes Problems

Raw fuel smell when vehicle is at idle. Breaks are very loud at low temperatures. Very squeaky like metal on metal yet the brakes are like new from Mercedes dealership.

Continuous problem with brakes squealing very loud. Have had brake pads replaced and taken to dealership multiple times to no resolution. It is a huge problem with how loud it is not to mention unsafe and making me feel uneasy about them giving out at any time. This is ongoing from several years ago

BRAKES SCREECH LOUDLY WHEN IN REVERSE CAUSING NOISE DISTURBANCE AND CONCERN ABOUT POSSIBLE SAFETY ISSUE. THIS HAS BEEN AN ON-GOING PROBLEM FOR SEVERAL MONTHS AND IS GETTING PROGRESSIVELY WORSE. APPARENTLY, THIS DEFECT WITH BRAKES IS WELL KNOWN TO MERCEDES-BENZ BUT THEY HAVE NOT ISSUED A PROPER FIX OR RECALL FOR THE PROBLEM. VEHICLE PURCHASED PRE-OWNED FROM MERCEDES-BENZ DEALERSHIP IN WALNUT CREEK IN 2018.

I BOUGHT A NEW 2016 MODEL (FEB. 2016), AROUND NOV 2016, THE ROTORS STARTED MAKING SQUEAKING NOISE WHEN BACKING UP, SO I TOOK TO DEALER TO DIAGNOSE. AT FIRST, THEY COULDN'T FIND THE ISSUE BUT AFTER READING ON THE MERC FORUM, I TOOK THE CAR BACK TO DEALER (JAN. 2017), ASKED TO CHECK THE ROTORS (NOT JUST THE BREAKS), FOUND THE ISSUE AND I PAID FOR THIS REPAIR. FAST FORWARD, JAN 2018, BROUGHT THE CAR BACK BECAUSE THE SAME SQUEAKING SOUND CAME BACK. I CALLED MERC CUSTOMER SERVICE, S/W "IRENE", AND SHE SAID THEY ARE AWARE OF THE ISSUE AND SHE WILL WORK WITH DEALER TO SEE IF THEY CAN FIX W/O FEE. SO LONG STORY SHORT, NEITHER THE DEALER NOR MERC ARE WILLING TO ADMIT THAT THIS IS A KNOWN ISSUE AND WON'T PAY FOR THE REPAIR. THEY ARE WILLING TO GIVE ME "15%" DISCOUNTS. SO, I AM WRITING TO ASK FOR YOUR HELP, PLEASE LET ME KNOW IF OTHER OWNERS HAVE SAME ISSUE, SHOULD THIS BE AN OVERALL RECALL?

PURCHASED THE CAR NEW FROM DEALER IN MARCH 2016. BRAKES SQUEAL IN REVERSE WHEN THERE'S COLD WEATHER. THE DEALER HAS REPLACED BREAK PADS AND ROTORS 3 TIMES BUT STILL THE SAME ISSUE; I'VE BROUGHT IT IN FOR THE SAME PROBLEM OVER 4 TIMES. THE LATEST 'FIX' WAS JANUARY 2018.

TL* THE CONTACT OWNS A 2016 MERCEDES-BENZ GLC300. WHILE DRIVING 5 MPH, THE BRAKES MALFUNCTIONED WITHOUT WARNING. THE CONTACT DEPRESSED THE BRAKE PEDAL AND THE VEHICLE SURGED FORWARD INDEPENDENTLY. AS A RESULT, THE VEHICLE CRASHED INTO THE CONTACT'S BARN. THE AIR BAGS DID NOT DEPLOY. A POLICE REPORT WAS NOT FILED. THE CONTACT SUSTAINED SEVERE WHIPLASH TO THE NECK AND WRIST PAIN FROM THE CRASH. MEDICAL ATTTENTION WAS REQUIRED. THE VEHICLE WAS TOWED TO MERCEDES-BENZ OF FAIRFIELD (2950 AUTO MALL PKWY, FAIRFIELD, CA 94533), BUT THE DEALER COULD NOT DUPLICATE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE BY VOICEMAIL, BUT NEVER CALLED BACK. THE FAILURE MILEAGE WAS APPROXIMATELY 6,000.

I HAVE A VERY LOUD SCREECHING SOUND WHEN I TAKE REVERSE. I REPORTED THIS ISSUE WHEN I TOOK THE CAR FOR THE FIRST SERVICE. I WAS TOLD IT WAS FIXED BUT IT CAME BACK WITHIN A WEEK. THOUGH I OWN A NEW CAR FEELS EMBARRASSING WHEN I REVERSE OUT OF MY GARAGE WHEN THE WHOLE NEIGHBORHOOD COULD HEAR THE SCREECHING NOISE.

PIERCING BRAKE SQUEAL WHEN APPLYING BRAKES UNDER ALL DRIVING CONDITIONS. PROBLEM ARISES AFTER OWNING BRAND NEW GLC300 FOR 8 MONTHS (10,000 MILES). PUBLIC SAFETY ISSUE: DRIVER HESITANT TO APPLY BRAKES TO AVOID UNPLEASANT SOUND AND EMBARRASSMENT - ESPECIALLY IN PUBLIC PLACES, SUCH AS MALL PARKING LOTS, SCHOOL ZONES, CROSSWALKS, INTERSECTIONS, STOP-N-GO TRAFFIC. MERCEDES BENZ DEALERSHIP CHARGING $260 TO DIAGNOSE CAUSE OF PROBLEM. *TR

BRAKES HAVE GONE FROM SQUEAKING TO DEAFENING SQUEAL AND DO NOT SEEM TO STOP AS QUICKLY. VERY SPONGY. DEALER SAYS THEY WONT HAVE REPLACEMENT PARTS FOR MONTHS. CONCERNED WE SHOULDNT BE DRIVING THE CAR AND DONT TRUST THE DEALER TO BE TRUTHFUL

BRAKES STARTED TO SQUEAL WHEN BACKING UP AT SLOW SPEEDS. THIS PROGRESSIVELY GOT WORSE OVER A COUPLE OF MONTHS, UNTIL IT IS NOW EXTREMELY LOUD. IT SEEMS TO BE WORSE WHEN IT IS COLD. 3 MERCEDES-BENZ DEALERS HAVE ALL SAID IT IS A KNOWN ISSUE AND TO STANDBY FOR A PERMANENT FIX. STARTED AT ABOUT 5,000 MILES ON CAR, NOW HAVE ABOUT 6500.

BRAKES AND BRAKE ROTORS SCREECH EXCESSIVELY WHEN MOVING FROM PARK, FORWARD OR BACKWARDS AND WHILE BRAKING AT STOP LIGHTS AND STOP SIGNS. REPORTED TO DEALER AND MERCEDES - NO ACTION. CONCERNED THAT BRAKES MAY FAIL AT A CRITICAL TIME OR THAT ROTORS WILL BE DAMAGED BEYOND REPAIR AND CAUSE FAILURE. *TR

HAVE A 2016 GLC300 WITH UNDER 5,000 MILES AND THE BRAKES SQUEAL IN REVERSE. THE DEALERSHIP REFUSED TO ATTEMPT REPAIRS AS THEY WERE TOLD BY MBUSA THAT THE COMPANY IS AWARE OF THE PROBLEM AND THE ENGINEERS ARE LOOKING FOR A FIX. SAME WAS TOLD TO ME BY MBUSA CUSTOMER SERVICE. RIDICULOUS TO PAY THIS MUCH FOR A CAR THAT HAS A KNOWN PROBLEM WITH NO RESOLUTION IN SIGHT. THEY CLAIM IT IS NOT A SAFETY ISSUE BUT WILL NOT PROVIDE IT IN WRITING AT THE DEALERSHIP.

I PURCHASED THE CAR IN MAY 2016. BY AUGUST 2016 THE BRAKES STARTING SQUEALING VERY LOUDLY WHEN BACKING OUT OF GARAGE, PARKING SPOT, ETC. I TOOK THE CAR TO THE MERCEDES DEALERSHIP IN NOVEMBER 2016 AND WAS TOLD THEY ARE AWARE OF THE PROBLEM BUT THERE IS NOT FIX. I AM AFRAID TO USE THE BRAKES WHEN I BACK UP BECAUSE OF THE HURTFUL NOISE. THERE MUST AT LEAST BE A TEMPORARY FIX?

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

TL* THE CONTACT OWNS A 2016 MERCEDES-BENZ GLC 300. WHILE DRIVING AND DEPRESSING THE BRAKE PEDAL, THE CONTACT HEARD A SQUEALING NOISE COMING FROM THE BRAKES. THE VEHICLE WAS TAKEN TO THE DEALER, BUT WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 6,000.

TL* THE CONTACT OWNS A 2016 MERCEDES-BENZ GLC 300. WHILE THE VEHICLE WAS IN MOTION, THERE WAS AN ABNORMAL NOISE COMING FROM THE FRONT END AND REAR BRAKES. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED, BUT NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 4,500. UPDATED 05/02/17*LJ *CN

LEASED THE CAR WITH 4,000 MILES ON IT (IT WAS A LOANER) AND AFTER DRIVING IT FOR A COUPLE OF WEEKS THE BRAKES STARTED TO SQUEAL WHEN BACKING UP. CALLED SERVICE AND I WAS TOLD THIS WAS "NORMAL" BECAUSE OF THE HUMIDITY IN THE AIR. DEALT WITH IT FOR ANOTHER COUPLE OF WEEKS AND CALLED SERVICE AGAIN. THIS TIME I WAS TOLD THERE WAS A "PROBLEM" WITH THE BRAKE PADS AND THEY WERE WAITING TO GET THEM FROM GERMANY BUT IT WAS "NOT A SAFETY ISSUE". I'M VERY UPSET THAT THEY KNEW ALL ABOUT THIS WHEN I LEASED THE CAR IN SEPTEMBER 2016 AND NEVER SAID A WORD ABOUT IT. EXTREMELY UPSET BY HOW THIS IS BEING HANDLED BY MERCEDES. NEVER DID I EXPECT TO HAVE A PROBLEM LIKE THIS WITH A $50,000 CAR!!!! MERCEDES SHOULD MAKE DUE ON THIS AND LET THE CUSTOMER RETURN THE VEHICLE. WHY SHOULD I BE PAYING FOR THIS VEHICLE EVERY MONTH AND NOT HAVING THIS ISSUE FIXED? THIS HAS DEFINITELY PUT A BAD TASTE IN MY MOUTH ABOUT MERCEDES. *TR

SCREECHING BRAKES WHEN CAR IS PUT IN REVERSE. TYPICALLY OCCURS IN COLD WEATHER. MERCEDES SAID THEY ARE AWARE OF THE ISSUE BUT NO FIX IS AVAILABLE. MERCEDES SAYS OCCURS WHEN VEHICLE HAS APPROXIMATELY 20K MILES ON THEM.

SQUEALING BRAKES! AT AROUND 6K MILES THE BRAKES STARTING SQUEALING. IT WAS VERY LOUD AND EMBARRASSING. WE TOOK IT IN AND THEY REPLACED THE BRAKES, THE ISSUE STILL PERSISTED. WE'VE SINCE BEEN TOLD THE MANUFACTURER ACCIDENTALLY PACKAGED THE DEFECTIVE BRAKES SO OUR DEFECTIVE BRAKES WERE REPLACED WITH ANOTHER SET OF DEFECTIVE BRAKES. THAT WAS SIX MONTHS AGO (4/2017 NOW) AND WE ARE STILL HAVING THE SQUEALING ISSUE AND HAVE NOT BEEN OF MADE AWARE OF WHEN THE MANUFACTURER WILL ACTUALLY HAVE THE CORRECT REPLACEMENT BRAKES. THIS IS COMPLETELY UNACCEPTABLE AND GIVES ME ABSOLUTELY NO CONFIDENCE IN THE MERCEDES BENZ BRAND.

THE BRAKES HAVE A LOUD PIERCING SCREECH WHEN BRAKES ARE APPLIED. IT STARTED OUT AS AN OCCASIONAL NOISE AND NOW IT IS CONSTANT. I HAVE CONTACTED MB CUSTOMER SERVICE AS WELL AS THE DEALERSHIP WHERE I PURCHASED MY VEHICLE. ALL ADMIT THAT MB IS AWARE OF THE ISSUE BUT HAVE NO FIX OR SOLUTION. IT IS WELL DOCUMENTED WITH SEVERAL COMPLAINTS ON ALL OF MB SOCIAL MEDIA SITES. I AM BEING TOLD THIS IS NOT A SAFETY ISSUE AND THE VEHICLE IS " SAFE " TO DRIVE BUT THIS IS UNACCEPTABLE AND I AM AFRAID TO DRIVE MY VEHICLE NOW ESPECIALLY TRAVELING ON THE FREEWAY BECAUSE MY BRAKES SCREAM WHENEVER THEY ARE APPLIED.
